Procedures for clearing obstructions from the suction inlet tube.Prior to removing the intake hose, locate the sweeper in a area conducive to safe work practice. Assure thesweeper is parked with the brakes set and the auxiliary and chassis engine off.

On occasion, suction inlet tube may become clogged with obstructions such as debris and mud (using largeramounts of water in the intake of the sweeping head will assist in removing dirt or mud clogging with removal ofintake tube).

Exercise care when cleaning the inlet tube as sharp objects (hypodermic needles, glass, etc.) orhazardous materials may be present. Wear the appropriate protective equipment.

To Clear an Obstruction:

Remove the flexible intake tube at the bottom end, which is connected to the sweeping head, and clear tubeobstructions from the lower end.

“A” series sweepers will have quick “V” clamp or band clamp enabling the operator to disconnect the bottom of theintake tube from the sweeping head and clear any potential obstructions.

“S” series sweepers will have a removable band clamp enabling the operator to disconnect the bottom of the intaketube from the sweeping head and clear any potential operation.

Reconnect the flexible intake tube to the sweeping head and check for proper operation.

DO NOT raise the hopper and attempt to clean the obstruction from the top of the suction tube as a potential pinchpoint is created between the hopper and the top of the suction tube.

OPERATION SAFETY INSTRUCTIONS AND PRACTICES

Prolonged operation of the Sweeper may cause operator boredom and/or fatigue affectingthe safe operation of the Sweeper. It is recommended that the operator take scheduledwork breaks to help prevent these potentially impaired operating conditions. If possible,completely shut down the Sweeper, exit the cab and move around stretching your arms andlegs. Never operate the Sweeper in a fatigued or bored mental state that impairs properand safe Sweeper operation. (SWD-5)

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSEPERMANENT HEARING LOSS! Sweeper operation can often benoisy enough to cause permanent hearing loss. We recommend thatyou always wear hearing protection if the noise in the Operator’sposition exceeds 80db. Noise over 85db over an extended period oftime will cause severe hearing loss. Noise over 90db adjacent to theOperator over an extended period of time will cause permanent or totalhearing loss. Note: Hearing loss from loud noise [from sweepers,chain saws, radios, and other such sources close to the ear] iscumulative over a lifetime without hope of natural recovery. (SWD-6)

Do not operate, or perform maintenance to, the Sweeper while wearing loose fittingclothing. Entanglement of loose clothing with the rotating elements can result in seriousinjury or death. Stay clear of all rotating elements at all times. (SWD-7)

Use both hands for support when getting on and off the Sweeper. Use handholds andsteps on the Sweeper for support when boarding the Sweeper. Never use the Sweepercontrol levers for support when boarding the sweeper. (SWO-1)

Use available Sweeper handholds and steps to exit the Sweeper. Make sure you havesolid footing before stepping down. Be careful of your step and use extra caution whenmud, ice, snow, or other matter has accumulated on the steps or handrails. Never rush toexit or jump off the Sweeper. (SWO-2)

Do not attempt to mount the Sweeper or Truck while the machine is moving.Never attempt to mount a runaway Sweeper. Serious injury or death mayoccur from being run over by a moving Sweeper. (SWO-3)

BEFORE leaving the Truck’s seat, always engage the parking brake and/or set the Truck’stransmission in parking gear, stop the engine, remove the key, and wait for all moving partsto stop. Never dismount a Truck that is moving or while the Truck and Auxiliary enginesare running. Operate the Sweeper controls from the Truck seat only. (SWO-4)



SAFETYSA

FETY

Always wear a seat belt while driving the Sweeper during operation andtransport. Serious injury or even death could result from falling out of theTruck or from being involved in a collision. (SWO-5)

Start the Truck and Auxiliary engine only when seated and belted in theTruck’s operator seat. Operate the Sweeper controls only while properlyseated with the seat belt secured around you. Inadvertent movement of theTruck and/or Sweeper components may cause serious injury or death to theoperator and passersby. Read the Truck and Auxiliary Engine operator ’smanuals for proper starting instructions. (SWO-6)

Use the right side steering only for sweeping, and never while exceeding 15 MPH. Fortravel, the Sweeper must be driven from the LEFT side ONLY. If the Sweeper is to beoperated from the right hand side, make sure the Sweeper’s mirrors are aligned for visibilityfrom the right hand side steering position. (SWO-37)

Sweep only in conditions where you have clear visibility of the area being swept in daylightor with adequate artificial lighting. Never sweep in darkness of foggy conditions where youcannot clearly see at least 50 feet in front and to the sides of the Sweeper. Make sure thatyou can clearly see and identify passersby, steep slopes, ditches, drop-offs, overheadobstructions, power lines, oversized debris and foreign objects. If you are unable to seethese types of items, discontinue sweeping until visibility improves. (SWO-8)



SAFETYSA

FETY

Transport the Sweeper only at safe speeds. Serious accidents and injuries can result fromdriving this Sweeper at unsafe speeds. Become familiar with the driving characteristics ofthe Truck and how it handles before operating or transporting on streets and highways.Make sure the Truck’s steering, brakes, and wheels are in good condition and operateproperly.

Before transporting the Sweeper determine the safe transport speeds for you and the machine. Make sureyou abide by the following rules:

• Test the Sweeper at a slow speed and increase the speed slowly. Apply the brakes smoothly to determinethe stopping characteristics of the Truck equipped with the Sweeper. As you increase the speed of theTruck, the stopping distance increases. Determine the maximum safe transport speed for you and theSweeper. When driving down a hill or on wet or rain slick roads, the braking distance increases: useextreme care and reduce your speed. Do not operate the Sweeper with weak or faulty brakes.

• Obey all traffic laws and regulations. Never exceed the posted speed limit.

• The Sweeper has a high center of gravity that may be further increased when carrying a loaded hopperand/or a full water tank. Use extreme caution when transporting at highway speeds. Slow down for sharpcorners to avoid tipping or turning the Sweeper over.

• Only transport the Sweeper at the speeds determined as safe and which allow for proper control of themachine while driving and stopping during an emergency.

• When operating in traffic, use the Sweeper’s directional indicator or signal lights to indicate yourmovement. Always use the Sweeper’s flashing signal lights and other equipped warning features to alertmotorist of your presence and slow moving speed when sweeping in traffic. Be Aware of Traffic AroundYou and Watch Out for the Other Guy. (SWO-9)

When transporting the Sweeper between locations, follow all local traffic laws andregulations. Disengage all Sweeper controls, raise all sweeping components, gutterbrooms, sweeper heads, make sure the hopper is completely lowered, and disengage allwarning signals prior to entering vehicle traffic. (SWO-10)

Before starting to sweep, the sweeping components must be engaged and operating at therated speed before moving forward. Sweeping debris before the Sweeper has reached itsrated operation speed may result in debris binding between the sweeping components orobstruction in the suction tubes. (SWO-11)

Do not exceed the rated operating speed for the Truck and Auxiliary engines. Excessiveoperating speeds can cause engine and Sweeper component failures resulting in possibleserious injury or death. (SWO-12)

Sweep at a speed that allows you to safely operate and control the Sweeper. Safesweeping speed depends on street condition and the type and amount of debris beingcollected. Normal ground speed range is between 1 and 3 mph. Slow down for corners,curbs, parked cars, protruding signs and other obstacles. Use slow traveling speedswhen operating on or near steep slopes, ditches, drop-offs, overhead obstructions, powerlines, or when debris and foreign objects are to be avoided. (SWO-13)



SAFETYSA

FETY

KEEP AWAY FROM ROTATING ELEMENTS including the Sweeper gutter brooms andsweeping head to prevent entanglement and possible serious injury or death. Be awarethat rotating elements can pull bystanders into the Sweeper. (SWO-14)

Never reach outside the Truck cab to pick up a foreign item or to clear an obstacle such asa tree limb or road sign impeding passage. Stop the Sweeper, shut down all sweepingcomponents, wait for all moving parts to come to a complete stop, and then exit the cab tohandle objects that are hindering Sweeper operation and passage. (SWO-15)

Do not operate the Sweeper if excessive vibration or noise exists. Shutdown the Sweeping components and the Truck and Auxiliary engines.Inspect the Sweeper to determine the source of the vibration or noise. Ifbrooms are loose, damaged, or missing, replace them immediately. Do notoperate the Sweeper until all necessary repairs have been performed and theSweeper operates smoothly. Operating the Sweeper with excessive vibrationcan result in component failure and broken objects being thrown outward athigh velocities. To reduce the possibility of property damage, serious injury,or even death, never operate the Sweeper with missing or damagedcomponents . (SWO-16)

Never attempt to sweep debris that is too large for the Sweeper to pick up (oversizedobjects such as broken limbs and discarded tires). Such objects may plug the sweepingcomponents and cause serious mechanical damage to the Sweeper. If possible, carefullyplace such objects out of the Sweeper and traffic path until properly removed by anothermeans. (SWO-17)

Objects such as wire, cable, rope, and chain can become entangled in the rotating parts ofthe sweeping components causing mechanical damage. Entangled items caught in thebrooms can sling outward possibly injuring or entangling the operator or passersby. Anyobjects that might become entangled in a sweeping component and those which could plugthe suction tubes should be removed from the area before beginning to sweep. (SWO-18)

Piled debris and water puddles left behind the Sweeper might pose a driving hazard tovehicle traffic colliding with the debris or losing traction on the material. It is recommendedto post warning signs alerting drivers of the Sweeper’s presence and the need to reducevehicle speed. If such hazards are left behind following the Sweeper’s passage, the areashould be swept a second time and any remaining hazards removed by an alternativemethod. (SWO-19)

Air enters the fan housing inlet with great force. Caution should be used when the powermodule is running and the hopper is raised. To avoid being pulled into the fan, do not wearloose clothes or position yourself or allow others near the fan housing inlet. Possible injuryor death could occur from being pulled into the fan. (SWO-21)



SAFETYSA

FETY

KEEP AWAY FROM SUCTION ELEMENTS including the suction head and suction hosesto prevent being drawn into the Sweeper and possible serious injury or death. Keep itemsthat might be drawn into the Sweeper head such as tools and replacement parts clear ofthe Sweeper before starting operation. (SWO-22)

Use extreme caution when dumping contents of the Sweeper. Be aware ofbystanders and animals in the area. Select a dump site on level ground andclear of overhead obstructions that could be hit when raising the hopper.

Serious injury or death to the operator, bystanders and animals could occur if precautions arenot taken when dumping the contents of the hopper.

• When positioning the truck at the dump station, choose an accessible location only on level ground.Raising the hopper on unlevel ground increases the possibility of tipping.

• Make sure the area is clear of ground and overhead obstructions.

• Never raise the hopper bin unless you can clearly see all overhead structures. Make sure you stay clear ofall utility lines.

• Do not dump the hopper over a pit area where the ground may cave in or is unstable.

• Make sure the outriggers contact solid stable ground before raising the hopper.

• Stay in the cab of the sweeper with the windows rolled up when dumping the hopper.

• Use care when positioning the Sweeper to the dump station. Your vision, especially to the side and rear ofthe Sweeper may be reduced by the size of the Sweeper. Use side and rear view mirrors to aid vision. Ifyou cannot see the dump site clearly, stop the Truck and examine the area. If necessary, requestassistance to guide you while backing the Truck into position.

• If the hopper will be in the raised position for more time than is normally required to dump, or if someoneis going to get under the hopper for repair, maintenance, cleaning or any other reason, secure the safetyprop into position.

• Never drive the Sweeper with the hopper in the raised position. Traveling with the hopperin the raised position increases the chances of colliding with overhead obstructions. Inaddition, the center of gravity of the Sweeper is higher with a raised hopper, making theunit more prone to tipping over. (SWO-23)

Use extreme caution when lowering or unfolding the Sweeper’s outriggers. Make sure nobystanders are close by or underneath the outriggers when activated. Allow ampleclearance around the Sweeper when lowering or raising the outriggers. Use extremecaution around obstructions including bystanders, passersby, curbs, buildings, and otherproperty. Use the Truck’s horn to warn of danger when outriggers are being lowered. (SWO-24)



SAFETYSA

FETY

Do not allow the Sweeper to come in contact with potentially dangerous and/or hazardousmaterial. Such hazards may include, but are not exclusively limited to, the following:•Fire Hazards- Fuel spills, burning material,

• Chemical Hazards- Chemical spills, discarded chemical containers, batteries,

• Biological Hazards- Decaying Carcasses, Biomedical Waste,

• Radioactive Hazards-Radioactive Waste, Radioactive Material,

• Cutting Hazards-Broken Glass, Lumber with Protruding Nails,

• Carcinogenic Materials-Asbestos,

• Corrosive Materials-Batteries, Acids and Bases.

In most areas, these types of material require special handling requirements for safe collection and properdisposal and should not be collected by the Sweeper, nor can they be disposed of in a general landfill site likemost swept waste. Contact the appropriate authority for the collection and disposal requirements of suchdangerous and/or hazardous material. (SWO-25)

Always wear required OSHA approved Personal Protective Equipment (PPE) when comingin contact with and removing potentially dangerous and hazardous material that has beencollected by the Sweeper or which is obstructing one or more Sweeper components. Payclose attention to dangerous and hazardous material including, but not exclusively limitedto, chemicals, decaying carcasses and sharp objects. (SWO-26)

Never sweep into hot or burning debris. A burning object, even as small as a lit cigarette,has the potential of igniting the collected waste inside the hopper, possibly destroying theSweeper and inflicting serious injury or death to the operator or passersby. (SWO-27)

Verbal communication near a Sweeper is difficult and dangerous. Operating instructionsand sweeping directions should be made prior to starting the Sweeper. Unclear andmisunderstood communication may lead to operator and bystander injury or death andequipment damage. If communication to the bystander by the operator is necessary,completely shutdown and exit the Sweeper. Never allow anyone to approach the Sweeperwhile in operation. (SWO-28)

Never allow children to play on, under, or around the Sweeper nor allow children to operateSweeper controls. Children can slip or fall off the Sweeper and be injured or killed.Children can cause the Sweeper components to shift or fall crushing themselves or others.(SWO-29)

Allow Sweeper passengers only in situations where their presence is involved in thesweeping operation (operator training, supervision, maintenance inspection). Never carrypassengers whose presence distracts from the safe operation or transport of the Sweeper.Passengers must be seated securely and belted in the cab’s passenger seat. Never allowany person to ride on any other location of the Sweeper during operation or transport.(SWO-30)



SAFETYSA

FETY

Extreme caution should be used by the Sweeper operator when operating near passersby.Stop sweeping if anyone comes within 25 feet of the Sweeper to prevent possible passerbyinjury or death from being struck from a thrown object, entanglement with the brooms, orrun over. (SWO-31)

Under certain conditions, the Sweeper’s brooms are capable of propelling objects up to 25feet. Be extremely careful when sweeping large dense objects, such as gravel or brokenglass, that might become propelled and cause bodily injury to passersby or damage toproperty such as windows and vehicles. (SWO-32)

Make sure that no bystander, animal or obstruction such as a vehicle,building, or street sign are behind the Sweeper when backing up. The designof the Sweeper impairs operator rear vision when backing. Use extremecaution to ensure that the Sweeper is not backed into the path of pedestrianor vehicle traffic. Serious injury or death and property damage could resultfrom running into, being crushed by, or run over by a Sweeper. (SWO-33)

Make sure no bystanders or animals are within 25 feet of the Sweeper whendumping contents from or cleaning the hopper. Hopper contents, which mayexceed several thousand pounds, could fall and crush a bystander or ananimal resulting in possible injury or death. (SWO-34)

MAINTENANCE AND SERVICE SAFETY INSTRUCTIONS AND PRACTICES

Use extreme caution when operating the Sweeper in traffic. To alert motorist of theSweeper’s presence, the Sweeper is equipped with warning signals, flashing lights, and abuilt-in arrow board. Optional electrical lights, flashers and a warning bar light, strobe, orbeacon may be positioned on top of the cab. Use all equipped warning signals to alertmotorist and pedestrians of the Sweeper’s presence and relatively slow speed. Seriousinjury or death and property damage may occur if a vehicle collides with the Sweeper. (SWS-3)

Before starting a sweeping operation, make sure all the warning signal lights areconnected, visible and working. Routinely inspect the Sweeper’s headlights, brake lights,backup lights, and turn signal lights for operational condition. Immediately repair non-functioning lighting. Always follow all local traffic regulations while operating the Sweeper.(SWS-4)

Always turn on all safety lights and flashers when you operate the Sweeper. It isrecommended that you preset the beacon/strobe light switches to ON, so lights go onwhenever the auxiliary engine is ON and lights go OFF whenever the auxiliary engine isturned OFF. This presetting action has the additional benefit of alerting the operator if theauxiliary engine is inadvertently left ON. (SWS-5)

Periodically inspect all moving parts for wear and replace whennecessary with authorized service parts. Look for loose fasteners, wornor broken parts, and leaky or loose fittings. Make sure all pins havecotter pins and washers. Serious injury may occur from not maintainingthis Sweeper in good working order. (SWM-1)

Inspect the entire Sweeper before each use. Accidents may occur or damage to theSweeper may result if the Sweeper is not maintained in good mechanical working order.

• Check for loose bolts, worn or broken parts, pinched hydraulic hoses, and leaky or loose fittings.

• Make sure all pins are secure and safety pins equipped.

• Make sure replacement parts (gutter broom heads) are the correct size and properly installed.

• Make sure all fluid levels are full and replenish as necessary.

• Make sure fuel, oil, and coolant caps are replaced and tightened.

• Make sure that the water tank cap is replaced.

• Check tire condition for tread wear and tire pressure at the rated PSI.

• Make sure that all safety shields and guards are attached and in good condition.

• Make sure all scheduled maintenance is up to date. (SWM-2)

The Schwarze A9 Monsoon air sweeper is mounted on a standard production truckchassis, providing the operator with unmatched convenience and comfort. Severaloptions are available, including air conditioning and dual steering.
The sweeper is powered by an auxiliary engine mounted on the sweeper frame to therear of the truck cab. It is fueled from a fuel tank located on the power module. Toprovide power to the sweeper, the engine propels a fan by use of a drive beltconnected to a bearing-mounted drive shaft. The balanced, abrasion-resistant fandraws air from inside the hopper and forces it out of the fan housing. To protect thefan housing from excessive wear, all Schwarze sweeper equipped with a replaceablerubber liner.

The fan draws air from the hopper and forces it down the pressure hose, then through an opening in the top ofthe sweeper head, and into the upper/rear pressure chamber. This air is pushed through the blast orifice, it istransformed into a high velocity stream that blast forward and downward onto the sweeping surface in thesweeping head’s lower/front chamber.

The sheer force of this air loosens debris, then picks it up and pushes it across the lower/front chamber of thesweeping head in a spiraling motion and moves it towards the suction inlet on the vacuum side of the sweepinghead. A series of flexible rubber flaps, called ‘Curtains’, are on the front and back of the sweeping head. Thesecurtains, along with the metal skid plates on each end, contain the hight velocity air within the sweeping head.The vacuum inside the hopper, caused by the fan’s draw of air, pulls the debris up through the suction hoseand into the hopper.

Once inside the hopper, a number of strategically placed water nozzles may be used to decrease the amountof airborne dust. As the dust comes in contact with the water spray, it becomes heavy. The dust and debris-laden air slows down when entering the large volume of the hopper, so heavier objects fall to the hopperbottom. The air is then drawn through a screen and into the dust separator in the front of the hopper. As air ispulled from the dust separator by the fan, it develops a spiraling action and centrifugal force throws theremaining fine dust against the walls of the separator, returning it through slots to the hopper bottom. The fanthen draws the cleaned air from the dust separator back into the fan housing and the cycle begins again.

For you convenience and safety, the sweeper is controlled via a console located in the cab of the truck. Thisconsole allow for remote operation of the hydraulic, dust suppression, and lighting systems, as well as thesweeper’s auxiliary engine. A remote switch panel located on the front of the power module is used to controlthe dumping. This outside panel safely positions the operator away from the rear of the sweeper, and allowadequate viewing of the dump area.

HYDRAULIC SYSTEMThe hydraulic system is comprised of electricalcontrol switches, hydraulic pumps, control valves,hoses, motors and hydraulic cylinders. Energy istransmitted from the sweeper’s auxiliary engine tothe dual output hydraulic pump unit by means of adirect-drive gear. The pump unit circulatespressurized fluid through hoses and control valvesthroughout the system. The hydraulic system iscontrolled by electrical switches mounted on thecontrol panel in the truck’s cab and on the front sideof the power module. Technically, these switchescontrol the hydraulic directional valves mounted themanifold, which route the flow of high pressurehydraulic fluid.

The two 2-stage manifolds are internally configuredwith the directional valves positioned in series. Thedirectional valves control hydraulic functions for thehopper, sweeping head, right gutter broom and leftgutter broom. If the unit is equipped with aMechanical-Pneumatic Powerhood SM or hydraulichand hose, a third single-stage manifold is added.

An auxiliary hydraulic unit, consisting of a 12 volt hydraulic pump and control switches, enables the sweeper’shydraulic devices to function when the power module engine is not operating. The unit is mounted to thesweeper frame just behind the power module and connected to the sweeper’s hydraulic system. It uses thetruck’s 12 volt battery to power the electric motor that drives the auxiliary hydraulic pump. The truck’s enginedoes not have to be running to activate the system. However, because of the electrical load generated by theunit, it is best to run the truck engine whenever possible. This auxiliary system is intended to be used formaintenance applications and in emergency conditions.

The auxiliary hydraulic pump is needed if the power module engine runs out of fuel or when an emergencyshutdown situation occurs. Without it, the sweeper head, brooms and any other device which normally functionwhen the power module engine is running would not operate. The 12-volt auxiliary unit can be used to power

ELECTRICAL SYSTEMThe Schwarze A9 Monsoon employs a standard 12 volt electrical system. The system is protected by an 80ampere. breaker (attached to the battery box) and resettable circuit breakers (in the console box).

LIGHTS, FLASHERS, ALARMTo increase operational safety, the sweeper may beequipped with a number of optional electric lightsand flashers. Spotlights are available for the broomand hopper to enable the driver/operator to see wellwhen operating at night. A flashing warning barlight, strobe or beacon may be positioned on the top

of the cab. These are used to alert motorists andpedestrians of the presence of the relatively slowmoving sweeping machine. An additional rear stoplight is positioned in the center of the hopper backpanel for added safety.

All lights are controlled by toggle switches mountedon the console inside the truck cab. Always keep alllights operating properly.

In addition to other safety features, a backupwarning alarm is standard. The high-pitched backupalarm warns bystanders that the sweeper is movingin reverse.

DUST SUPPRESSION SYSTEMAir sweepers depend on a stream of high pressureair to blow dirt and other objects across the width ofthe sweeper head. This produces dust, which isremoved from the sweeper head by the vacuumsuction hose. To avoid unnecessary wear to theblower fan, ducts, head and hopper, it is necessaryto control the amount of dust forced through thesweeper. This is accomplished by introducing waterspray at various locations on both the inside andthe outside of the sweeper.

The standard Schwarze A9 Monsoon dustsuppression system uses two durable rust-freepolyethylene water tanks with a combined capacityof 250 gallons. Depending on the truck chassis onwhich the unit is mounted, an additional (optional)350 gallon polyethylene tank may be addedbetween the unit and the truck cab to increase theamount of water available to the dust suppressionsystem.

Water exits the bottom of the standard water tank and passes through a ‘Y’ strainer, located beneath the watertray on the right side of the sweeper. The ‘Y’ strainer purifies the water by the removal of debris particles. Theremoval of these particles from the water system reduces the chance of dust suppression system failure due toclogged water nozzles.

After passing through the ‘Y’ strainer, the water ispulled into the water pump. The water pump is a 5stage diaphragm electric pump. The water pump iscapable of 5.8 gpm @ 50 PSI. The system shouldbe set at 70 PSI.

Once the water has reached the water manifold, thesolenoid valves, attached to the manifold, may beelectrically opened from the sweeper’s console tosupply the desired dust suppression systemfunction (i.e., sweeping head, hopper, spray baretc.) with water.

A hose connects one end of the water manifold to aspigot, affixed to the front of the fill hose rack. Thisspigot provides an attachment point for the optionalhigh volume wash down hose as well as a drain forthe manifold.

If the water in the reservoir becomes too low, a sensor, located in the reservoir’s wall, shuts down the waterpump, preventing the water pump from running when dry.

CONSOLEThe central control panel is mounted in a console inthe truck cab. For operator safety and convenience,all controls are within easy reach of the driver/operator, whether operating from the left or rightside position. This console allows remote operationof all hydraulics, dust control water systems andlighting systems, as well as the power moduleengine for the sweeper. These controls are allelectrically operated. All electrical elements in thesystem are protected by resettable circuit breakers.

In addition to the controls on the sweeper’sconsole, there are five extremely important gageswhich must be monitored periodically by the driver/operator. These are the engine’s tachometer, oilpressure gauge, water temperature gauge, hourmeter, and voltmeter.

POWER MODULE ASSEMBLYThe sweeper’s power module assembly consists ofthe welded frame, engine skid, diesel engine, fanand fan housing, hydraulic unit and water tank. Thepower module assembly provides power for thesweeper, and its modular design allows easyaccess to all major parts.

AUXILIARY ENGINEThe sweeper engine, which is diesel-powered, is mounted on an adjustable frame tray called the engine skid,and is normally fueled by the truck’s main fuel tank. Power produced by the engine is transmitted to the fan bya drive belt. For safety and convenience, all controls and gauge for the sweeper engine are located inside thecab on the central console.

For detailed information on the sweeper’s engine, consult the engine’s Owner’s Manual which is attachedseparately.

FAN DRIVE BELTThe fan is connected to the rear of the power module engine by a five-groove drive belt. This belt is loopedaround the drive pulley on the power module engine and the pulley on the fan shaft. For safety, it is protectedby a metal belt guard.

FANThe Schwarze-exclusive WhisperWheel™ is acentrifugal, backward curving fan. This uniquedesign results in reduced fan noise and requiresless auxiliary engine horsepower to operate. Thefan produces the air pressure and vacuum requiredfor the sweeper to operate. It is a balanced,reinforced, abrasion-resistant fan on a bearing-mounted drive shaft. Construction is of heavy steel.The fan is propelled by the power module engine,and is located within the fan housing attached to therear of the power module.

FAN HOUSINGThe fan housing is mounted to the rear of the powermodule. Because of the sand blast effect of theairborne material traveling through the dustseparation chamber and into the fan housing, theinside of the fan housing is protected by a bolt-onreplaceable rubber liner.

A sweeping condition bleeder, located in the fanhousing’s snout, can be used to restrict the flow ofair entering the sweeping head. The bleeder isdamper door operated by an electric actuator. Aswitch on the control panel console mounted in thetruck cab operates the actuator. During normaloperating conditions, the bleeder door is closed andair from the fan is forced into the sweeper head.

In sweeping conditions where there areconcentrations of leaves or other light debris, theforce of the blast orifice air pushing against the rearside of the main curtain prevents light debris from entering the head. By opening the bleeder door, air from thefan is diverted away from the sweeping head’s pressure chamber and exhausted out of the sweeper. The airflow pressure is decreased in the pressure chamber and blast orifice, which relieves pressure against the rearside of the main curtain. This allows light debris to push under the main curtain and into the sweeper head.

SWEEPING HEADThe sweeping head is the actual sweeping component of the air sweeper. It is attached to the underside of theframe by drag arms, tension springs, and two hydraulic cylinders that are mounted on each side of thesweeper head. The hydraulic cylinders and tension springs control the vertical movement of the head. A switchmounted on the control console in the truck cab operates the cylinders.

The sweeping head is connected to the fan housing and hopper by two hoses, one on the pressure side andone on the vacuum side. On the pressure side, the hose runs from the fan housing to the pressure inlet tube onthe head. One end of the vacuum hose is connected to the suction inlet tube on the head, and the other endattaches to a frame transition tube that the hopper intake tube seats against. Both hoses are held in place by ametal band at the top and bottom of each hose.

STANDARD SWEEPING HEADThe standard sweeping head is designed so the airpressure from the fan will produce the maximumcleaning performance. High velocity air from the fanenters the head through a pressure inlet tube, andis channeled into the pressure chamber located inits upper, rear section.

A slot, which is angled across the full width of thehead at the bottom of the chamber, is called the‘blast orifice.’ The air stream is forced forward anddownward, out of the blast orifice and onto thesweeping surface below. This blast of air loosensdebris and pushes it in a spiraling motion towardthe suction inlet on the right hand side of the head.An optional, adjustable blast orifice is available.This sweeping head option uses jack screws tomanipulate a movable blast orifice rear lip, allowingthe air-stream velocity to be set to individualoperator preference.

Skid plates at each end, and a series of flexible rubber flaps in both front and rear, contain the powerful airstream beneath the sweeper head. As the debris-laden air nears the suction inlet, vacuum from the fan drawsthe debris up and out the suction tube.

MECHANI-PNEUMATIC SWEEPING HEADThe Mechani-pneumatic Powerhood™ is a newinnovation in sweeping. Schwarze Industriesinvented the patented concept of positioning thebroom in the front of the sweeping hood (also called‘sweeping head’), rather than at the rear. Thisunique design means the broom scrubs thesweeping surface directly in front of the sweepinghood’s full-width blast orifice. The angled scrollbroom has been specifically engineered to enhanceits windrowing ability. This combination of broomdesign and broom location provides the Schwarze-exclusive Powerhood with the capability oftransferring large amounts of material to the pickupside of the sweeping hood. The Mechani-pneumaticPowerhoodSM also features an adjustable blastorifice, allowing the orifice air-stream velocity to beeasily adjusted according to individual operatorpreference.

HopperThe sweeper’s hopper is designed to contain thematerials collected during the sweeping operation.It is constructed of heavy gauge steel and shapedto distribute the load evenly and centrally over therear axle. A welded frame mounted on the truckchassis supports the hopper, as well as thehydraulic cylinders which enable it to dump directlybehind the rear wheels. Access doors on both sidesof the hopper allow objects too large to be pickedup by the sweeper head to be placed directly intothe hopper. These side access doors also provide aclean, convenient means of washing out thehopper. The hopper assembly incorporates a waterspray system, steel screen filter and a dustseparator to remove airborne debris.

Gutter BroomThe Schwarze A9 Monsoon may be equipped withone or two rotating hydraulic brooms to complementthe air sweeper system. They are designed to digdebris loose from the gutter, or similar areas, anddirect

it across into the path of the sweeping head.

Brooms may be mounted on both the left and rightsides of the sweeper under the chassis, to the rearof the cab. They are suspended from the frame onhydraulically controlled arms, and are operatedfrom the control console within the truck cab. Thehydraulic motors which turn the broom heads aremounted inside a disc on the end of each arm.

When not in use, the brooms are hydraulically held and locked in position under the sweeper and off thepavement. This unique design enables the sweeper to have a minimum width and yet provide the maximumground clearance possible when the brooms are in the traveling position.

GUTTER BROOM POWER TILTThe Schwarze A9 Monsoon gutter broom employsa small turnbuckle within the broom arm todetermine the gutter broom disc’s side-to-side tilt.Tilt, a key element in setting the gutter broompattern, is crucial in determining where debris sweptby the gutter brooms will be thrown. The power tiltoption replaces the standard gutter broom arm tiltturnbuckle with an hydraulic cylinder. By toggling anin-cab console control panel switch, the hydrauliccylinder may be extended or retracted to changethe attitude of the gutter broom disc. This option isespecially useful in areas where gutter depth variessignificantly. The power tilt allows the operator toadjust the gutter broom disc tilt on the run, ratherthan having to stop, exit the cab and manuallyadjust the tilt. NOTE: The gutter brooms must beon the ground running in order to actuate the gutterbroom tilt.

GUTTER BROOM EXTENSION OVERRIDE (GEO)The gutter broom extension override system allowsthe operator to switch from normal gutter extension(for wide sweeping or curb-line work) to an inboardoperation of one or both gutter brooms. All controlsare located in the cab. In this mode, the gutterbrooms are pulled inward by actuators from theirstandard sweeping position to operate on thesurface immediately in front of the sweeping head.The result is an advantageous digging agitation ofany stuck-down material prior to the sweeping headpassing over.

CAMERA SYSTEMThe optional camera system may be used to increase an operator’s field of vision. A camera is mounted belowthe right water reservoir just behind the gutter broom. The camera is mounted to point forward and down. Thisangle allows observation of the gutter broom’s operation as well as provides a view of approaching curb lineobstacles. A second camera, mounted at the rear of the hopper, views what is directly to the rear of thesweeper. When the sweeper is shifted into reverse, the picture on the dash-mounted monitor automaticallyswitches to the rear view. Both cameras provide a wide field of vision.

HAND HOSEA hand hose designed to clean areas inaccessibleto the sweeper head, such as shallow catch basins,highway medians, railings, etc., may be attached tothe rear of the sweeper. It operates from fan-produced vacuum within the hopper. The handhose is a piece of flexible tubing that is 12-1/2 feetlong and 8 inches in diameter. One end is mountedto a transition plate, which pivots across a hole inthe rear of the hopper. The free end is fitted with a52-inch aluminum nozzle.

A hinged boom suspends the weight of the hose,providing the operator with greater control. Asuction inlet block-off plate, stored on the side of the

power module, is used to increase suction when avery heavy concentration of debris must beremoved.

MAGNETA magnet may be mounted to the front of the sweeper to remove objects that may damage truck tires andcause down time for the sweeper. Two types of magnets are available:

• A bar magnet, which is raised and lowered using an electric actuator. Objects picked up by this type of magnet must be removed manually.

• An encased magnet, which uses actuators to raise and lower as well as dump objects from the bottom of the magnet.

HIGH VOLUME WASHDOWNAn optional, high volume washdown hose and spray nozzle are available. The hose taps into the sweeper’swater system via the water spigot located on the front of the fill hose rack. The spray nozzle may be set from awide spray to a narrow, high pressure stream. The washdown allows the operator to clean the sweeper while inthe field regardless of water source availability.

ADDITIONAL WATER TANKIn addition to the Schwarze A9 Monsoon’s standard250 gallon water tanks, an additional, optional 350gallon water tank may be installed to the watersystem on your sweeper. If this option was chosen,it will double the dust suppression system’s waterreserve. That will provide extended time sweepingand less time lost filling the water tank. If youchoose to do so in the future, the second water tankmay be added as a retrofit. The additional watertank is not available on conventional chassis.

FRONT SPRAY BARA front spray bar is available and may be added tothe sweeper’s dust suppression system to increasedramatically the amount of water that may beapplied to the sweeping surface. The spray bar,mounted to the front bumper, employs 7 spraynozzles whose overlapping patterns are used tothoroughly and evenly dampen the area in front ofthe sweeper to reduce airborne dust. The spray baris operated by a switch located on the in-cabconsole.

HOPPER DELUGEA tube protruding from the outer skin of the reardump door is connected to two large water nozzlespositioned inside the hopper. A 2-1/2” fire hose,supplied with the hopper deluge system, may beattached to both the tube and a fire hydrant. Whenthe hydrant is opened, the inside of the hopper iswashed with a massive amount of pressurizedwater. This ‘deluge’ blasts free most dirt andstubborn grime adhering to the inside of the hopperand hopper screen, simplifying and shortening thesweeper’s cleanup.

HOPPER DRAINAlthough certain instances may require that liquidpicked up by the sweeper be removed to aspecified dump site. Often, it would be preferable toreturn any unwanted liquid, such as rain water, tothe sweeping surface to reduce load weight/massand permit longer dumping intervals. An optionaldrain located in the rear door offers the capability ofdraining liquid from the hopper while the sweeper isoperating. This allows the sweeper to be operatedin a business-as-usual fashion even during wetweather.

Most sweeper devices requiring simple activation and deactivation are operated with 2-position ON and OFFswitches. These devices perform the following functions:

• Safety features (warning lights and safety flashers)

• Dust Suppression

Other devices require a 3-position switch. These switches are used for components which employ extensionand retraction or direction reversal. In many instances, one or both of the activation positions are momentaryON, meaning the switch will stay in that position only as long as it is manually held there. When released, theswitch will automatically return to the center OFF position. On the following page is a table which lists thesweeper functions and their switch positions.

3.2 Auxiliary Engine Start-UpSTARTING THE ENGINE

Before starting the engine is a confined area, verify that proper outlet exhaust ventilationequipment is installed. Always use safety approved fuel storage and piping.

Perform all pre-starting checks in the Start-Up Checklist

1. Turn the key switch clockwise to crank the engine.

A buzzer will sound until the auxiliary engine reaches operational oil pressure.

2. When the engine starts, release the key so that it returns to the ON position.

NOTE: The sweeper is equipped with a shutdown system that requires a 10 second delay before attempting torestart the auxiliary engine.

To prevent possible damage to the starter and/or flywheel: If you release the key switchBEFORE the engine starts, you MUST wait until the starter and engine come to a completestop before attempting to restart the auxiliary engine.

3. Activate the electric throttle.

4. Check all gauges for normal engine operation. If operation is not normal, stop the engine and try todetermine the cause of the problem.

WARMING THE ENGINE

To assure proper lubrication, warm the engine by operating it at 1200 RPM with NO LOADfor 1 to 2 minutes. When operating at temperatures below freezing, extend this period to 2 to4 minutes.

1. Check the oil-pressure gauge as soon as the engine starts. If the gauge needle does NOT rise above the minimum oil-pressure specification of 103 kPa (1.03 bar; 15 PSI) within 5 seconds, stop the engine and try to determine the cause of the insufficient oil pressure.

2. Normal engine oil pressure is 380 ± 103 kPa (3.80 bar ± 1.03 bar; 55 ± 15 PSI) at rated full-load speed (1800-2500 RPM) with oil at the normal operating temperature of 105° C (220°F).

3. Watch the coolant temperature gauge. Do NOT place the engine under full load until it is properly warmed up. The normal engine coolant temperature range is 82°-94°C (180°-202°F).

NOTE: We advise operating the engine under a lighter load and at lower speeds than normal for the first fewminutes after start-up.

IDLING THE ENGINE

Avoid unnecessary engine idling and NEVER allow the engine to idle longer than 5 minutes. Prolonged idlingcould cause the engine coolant to fall below its normal range, in turn causing the following conditions:

• Crankcase oil dilution due to incomplete fuel combustion

• Formation of gummy deposits on valves, pistons and piston rings.

• Rapid accumulation of engine sludge and unburned fuel in the exhaust system

Slow idle for this engine is set at 850 RPM at the factory. If you must leave the engine running more than 3 or 4minutes, make sure the engine speed is at 1200 RPM.

DPF INDICATOR GAUGE

Exhaust Filter Cleaning ProcedureAutomatic (Auto) Exhaust Filter Cleaning:

Leave Cleaning Control switch in the middle position to allow for automatic cleaning of DPF. The automaticcleaning mode is recommended because it normally provides the best fuel economy and machine up-time.

• Exhaust filter cleaning will occur automatically based on need and opportunity.

• Exhaust temperature management and HC closing will be active, as needed.

• Elevated idle speed (return to) may be active.

Manual Cleaning:

The exhaust filter symbol must be present to request cleaning. This indicates the soot level is high enough toconduct a Manual Cleaning (PMC).

To request cleaning:

• The engine must be at idle speed.

• The DPF Interlock switch must be turned on.

• The Cleaning Control switch must be pressed up and held for three seconds continuously.



OPERATIONO

PER

ATIO

N

The ECU (Engine Control Unit) will acknowledge this request by illuminating the EFI indicator on the DPFindicator gauge.

During manual cleaning, engine speed will be increased by the ECU to 1800 rpm. This is different than theelevated return to idle during automatic cleaning. The operator must remain “Hands Off” or manual cleaningwill abort. Change in state of any interlock or throttle will result in an aborted manual cleaning.

Service Cleaning

Service Cleaning is not a normal operating mode It is not the same as Stationary Cleaning. Reaching soot level5 is a strong indication that something is wrong with the system or inhibit has been left on and warnings havebeen ignored. Service Cleaning can take several hours to complete and must be followed by a stationarycleaning. An authorized John Deere dealer must be contacted if a Service Cleaning is necessary.

3.4 Dual Steering OperationIf the sweeper is to be operated from the right hand side, realign the sweepers mirror’s forvisibility from the right hand side steering position.

In all sweepers containing the dual steering option, a switch must be toggled to designate the steering positionthat is to be empowered. Depending upon the truck model, this switch may be located in either the truck’s dashor sweeper console.

For travel, the sweeper must be driven from the left side only.

3.5 Sweeping Head OperationSTANDARD SWEEPING HEAD

The standard sweeping head is controlled by a control panel switch on the cab console. The switch is identifiedby the legend symbol shown below.

NOTE: The auxiliary engine must be running, or the ignition switch turned on and the auxiliary pump switchheld in the ‘ON’ position, before operating the sweeping head switch.

1. Push the switch so that the sweeping head lowers. Continue to hold the switch until the sweeping headrests fully on the sweeping surface. When the switch is released, it will return to the center, neutralposition.

2. To raise the sweeping head, push the switch in the opposite direction, continuing to hold the switch whilethe sweeping head raises. When the sweeping head bottoms against the upstops, release the switch.Again, it will return to the center, neutral position.

MECHANI-PNEUMATIC POWERHOOD

The powerhood is controlled by a cab console control panel switch. The switch is identified by the legendsymbol shown below.

NOTE: The auxiliary engine must be running or the ignition switch turned on and the auxiliary pump switchheld in the ‘ON’ position, before operating the sweeping head switch.

1. Push the cab console control panel switch DOWN so that the sweeping head lowers. The sweeping headlowers and the scroll broom within begins to rotate. Any time the scroll broom is in the raised position withinthe Powerhood, toggle the cab console control panel switch to the up position for one second to stop therotation of the scroll broom.

Never run the scroll broom when it is in the raised position within the Powerhood.

2. To raise the sweeping head, push the cab console control panel switch UP, continuing to hold the switchwhile the sweeping head raises. When the sweeping head bottoms against the upstops, release theswitch. It will return to the center neutral position.

NOTE: To raise or lower the broom within the Powerhood, only the igniting switch must be turned on. However,to raise and lower the Powerhood for the scroll broom to rotate, the auxiliary engine must be running or theauxiliary pump must be engaged.

NOTE: For normal debris pickup, use the Powerhood with engaging the scroll broom. However, when areas ofdeep dirt or sand are encountered, the scroll broom should be lowered to the sweeping surface. Once removalof the material form the problem area has been accomplished, the scroll broom should be raised until neededagain. In this way, by using the scroll broom only on an as-needed basis, the life of the broom may beextended.

The Powerhood’s scroll broom is controlled by a cab console panel switch. The switch is identified by thelegend symbol shown below.

1. To engage the scroll broom, push its cab console control panel switch DOWN to lower the broom. When the switch is released, it will return to the center neutral position.

2. To raise the broom, push the cab console control panel switch UP. Again, when released, it will return to the neutral position.

3.6 Bleeder Door OperationThe bleeder door is controlled by a control panel switch on the cab console. The switch is identified by thelegend symbol shown below.

The control panel switch controls an actuator that opens and closes a damper door located in the exhaust ofthe fan housing. This damper door, also known as the bleeder door, is normally closed. Only in instances oflight debris or leaves is the bleeder door opened.

NOTE: To open or close the bleeder door, only the auxiliary engine’s ignition switch must be turned on.

1. Push the switch to the UP position. Continue to hold the switch while the actuator opens the bleeder door.When the switch is released, it will return to its center neutral position.

NOTE: It requires approximately eight seconds for the bleeder door to reach its fully open position. However,the door may be positioned at any point between fully open or closed.

2. To close the bleeder door, push the switch to the DOWN position and, again, continue to hold the switch until the desired bleeder door positioning has been achieved.

NOTE: Using excess water to dampen leaves and other light debris tends to make them stick to the sweepingsurface. Sometimes neither the blast force nor the vacuum suction can remove lightweight debris in thiscondition.

3.7 Gutter Broom OperationThe gutter brooms are activated by a control panel switch (or switches) located on the cab console. Eachswitch is identified by the corresponding legend symbol shown below.

Gutter Broom Extension

Use the following procedure to operate the gutter broom under normal conditions in which street gutters areaccessible. The gutter brooms are designed to be full-floating. If you encounter an obstruction on the surface,the broom automatically lifts to go over it. As broom bristles wear away, the broom lowers to maintain contactwith the surface.

1. Start the auxiliary engine by following the procedures outlined in Section, ‘AUXILIARY ENGINE START-UP.’

2. Push the gutter broom switch(es) down to the RUN position. The gutter broom is lowered to the ground,begins to run, and extends to its normal operating position for sweeping.



OPERATIONO

PERATIO

N

Optional Gutter Broom Extension Override (GEO)

The next part of the procedure concerns use of an optional feature that allows you to adjust a gutter broomfrom its normal operating position inward, toward the centerline of the truck, so it can scrub the area thesweeping head will sweep. This feature is helpful if you encounter stubborn debris stuck to the surface in thepath of the sweeping head. The gutter broom GEO’s are controlled by a control panel switch located on the cabconsole. The switch is identified by the legend symbol shown below.

3. Toggle the gutter broom GEO switch up for retracting the gutter broom. The gutter broom will retractinward, toward the centerline of the truck, where it can pre-scrub material stuck to the surface in the path ofthe sweeping head.

4. To return a gutter broom to its normal operating position, toggle the gutter broom GEO switch down. Thiswill extend the broom. The gutter broom extends outward to its normal operating position for sweeping.

Optional Gutter Broom Tilt Cylinder

The next part of the procedure concerns an optional feature – the gutter broom tilt cylinder. Control panelswitches on the cab console activate cylinders on a gutter broom arm. If this sweeper has this feature, theoperator is able to control the angle of broom-disc tilt via these switches. If your sweeper does not include thisfeature, proceed to ‘GUTTER BROOM RETRACTION.’

The gutter broom remote tilt is controlled by a control panel switch located on the cab console. The switch isidentified by the legend symbol shown below. Note: The gutter broom must be down and running to activatethe tilt function.

5. Toggle the gutter broom tilt switch to the UP position, and hold the switch in that position until the broom istilted to the desired angle. Release the gutter broom tilt switch. When you release the switch it returns tothe center, neutral, OFF position.

6. Resume sweeping operations.

7. After the curb is scrubbed, toggle the gutter broom tilt switch in the opposite direction and hold the switch inthat position until the broom is correctly tilted for its normal sweeping pattern.

8. Release the gutter broom tilt switch. When you release the switch it returns to the center neutral OFFposition.

NOTE: The gutter brooms must be on the ground running to actuate gutter broom tilt.

NOTE: For optimum travel clearance, always return the broom tilt to normal tilt before retracting the broom.

10. On the cab console control panel, toggle the gutter broom switch to the UP position. Hold the switch in theUP position until the broom is fully retracted.

3.8 Hopper Operation Two sets of controls – one located on the control panel inside the cab and one mounted to the front of thepower module – are provided for hopper operation. When dumping, always use the outside set of controls. Bybeing out of the cab and to the side of the sweeper, the operator is provided a better view of the dumpingoperation.

The in-cab hopper control consists of a single dump switch. This switch is for maintenance convenience andmust only be used to raise or lower the hopper.

In-Cab Hopper Controls

The hopper may be raised and lowered by a control panel switch located on the cab console. The switch isidentified by the legend symbol shown below.

The auxiliary engine must be running, or the ignition switch turned on and the auxiliary pumpswitch held in the ON position, before operating the hopper dump switch. Due to theelectrical load generated when using the auxiliary pump, it is best to run the auxiliary enginewhenever possible.

This switch should only be used to raise or lower the hopper for maintenance purposes,never to dump the hopper.

1. Push the cab console control panel switch to the UP position. After a momentary pause the hopper willbegin to raise. Continue to hold the switch in the UP position until the hopper has been raised. When theswitch is released, it will return to the center neutral position.

NOTE: If the safety prop has been lowered into place, it must be returned to its travel position beforeattempting to lower the hopper.

2. To lower the hopper, push the cab console control panel switch in the DOWN position. Continue to hold theswitch to the DOWN position until the hopper has firmly seated itself against the intake and fan seals.

Outside Hopper Controls (Optional)

NOTE: The auxiliary engine must be running, or the ignition switch turned on and the auxiliary pump switchheld in the ON position, before operating the hopper dump switch. Due to the electrical load generated whenusing the auxiliary pump, it is best to run the auxiliary engine whenever possible.

1. Start the auxiliary engine following the procedures outlined in Section, AUXILIARY ENGINE START-UP.

2. Locate the outside hopper control panel and note the three switches labeled ‘DUMP’, ‘DOOR’ and‘LIGHTS.’

NOTE: The rear dump door must be opened first, and closed last in the dump procedure.

3. Toggle the ‘LIGHTS’ switch to the ON position.

4. Push the ‘DOOR’ switch to the UP position. Continue to hold the switch in the UP position until the reardoor is fully raised. When the switch is released, it will return to the center neutral position.

To ensure safe dumping, always use the outside hopper dump controls.



OPERATIONO

PERATIO

5. Push the ‘DUMP’ switch to the UP position. Continue to hold the switch in the UP position until the hopperis fully raised. When the switch is released, it will return to the center neutral position.

If you open the rear door or raise the hopper for more time than is normally required todump, or you are going to get under the hopper for any reason, always secure the safetyprops into position.

The hopper’s safety prop is accessible when the hopper is completely raised. It is located in the left fender well.It is designed to unhook from its retainer on the hopper frame and swing down into a stop on the frame. Ahandle is provided to aid the operator in positioning the prop into the stop.

3.9 Magnet OperationThe magnet is controlled by a control panel switch located on the cab console. The switch is identified by thelegend symbol shown below.

NOTE: If the magnet is to be lowered or raised, the ignition switch must be turned to the ‘ON’ position.

1. Push the cab console control switch to the DOWN position. Continue to hold the switch in the DOWNposition, holding it in place for a few moments to be sure the magnet has fully lowered. The magnet willautomatically stop when it reaches the proper distance from the ground. When the switch is released, it willreturn to the center, neutral, position.

1. Begin sweeping

2. When the magnet is not longer required, push the cab console control switch to the UP position, holding itin place until the magnet is fully raised.

If the unit is equipped with an encased magnet, material on the bottom of the magnet may be dumped byoperating a control panel switch located on the cab console. The switch is identified by the legend symbolshown below.

This switch controls an actuator which lifts the inner magnet from the bottom of the outer case, releasing anyobjects which have been attracted there. If the unit is equipped with one of the bar type magnets, objects mustbe manually removed.

3.10 Hand Hose OperationThe hand hose is a piece of flexible tubing with an aluminum nozzle, and is mounted on a spring or hydrauliccylinder boom hinged to the rear of the hopper. The hose operates via suction with the hopper.

1. Release the rubber straps that hold the hose and aluminum nozzle to the back door of the hopper.



OPERATIONO

PER

ATIO

N

NOTE: If the boom is hydraulic, the auxiliary engine ignition switch must be on to power the hydraulics.

2. To release the hand hose boom from its catch, choose on:

• If the boom contains a spring, pull down on the hose and swing the boom free.

• If the boom contains an hydraulic cylinder, use the toggle switch located in the hand hose handle to extendthe cylinder. Lower the end of the boom, allowing it to swing free of its catch.

3. Locate the hopper transition cover plate in the upper right corner of the rear door.

4. Pull down on the handle latches on either side of the hopper transition cover plate. Swing it open and to thefar right.

5. Now swing the hose suction transition plate to cover the hole in the hopper door.

6. Secure the hose suction transition plate in place, using the handle latches.

Never point the hand hose nozzle toward another person. Serious injury could result.

When a very heavy concentration of debris must be removed, installation of the block-off plate may be needed.The plate is used to block off the hopper’s intake tube, resulting in an increase in hand hose suction. The plateis stored on the right side of the power module.

7. Locate the block-off plate inside the toolbox at rear of truck.

8. Remove the block-off plate from the toolbox.

Never insert the block-off plate while the engine is running at high RPMs. Keep hands awayfrom dangerous pinch area.

9. Raise the hopper (See Introduction Section, ‘HOPPER OUTSIDE CONTROLS’) just enough to insert theblock-off plate onto the top of the frame’s transition.

When using the hand hose in or around water, never hold the end of the nozzle completely under the water’ssurface. Doing so will draw water up into the nozzle until the water pressure is equal to the suction within thehopper. When this occurs, the blower fan cannot draw air through the fan inlet and all suction is lost. Positionthe nozzle to where both liquid and air are vacuumed.

3.11 Lights and Flashers OperationNOTE: We recommend that you preset the beacon/strobe light switches to ON, so lights go on whenever theauxiliary engine is ON and lights go off whenever the auxiliary engine is turned OFF. This presetting action hasthe additional benefit of alerting you if the auxiliary engine is inadvertently left ON.

Always turn on all safety lights and flashers when you operate the sweeper.

1. Locate the labeled warning light and/or flasher switch(es) on the cab console control panel.

2. Toggle the switch(es) to ON.

3. Complete the sweeping operation.

4. On the cab console control panel, toggle the warning light and/or flasher switch(es) to OFF.

3.12 Dust Suppression System OperationFor filling procedures of the dust suppression system’s water reservoir(s), please refer to Section, ‘WATERRESERVOIR REFILL.’

Electrical switches in the console operate the following nozzle locations for the dust-suppression system:

• Spray nozzles on the intake tube of the hopper

• Spray nozzles on the sweeping head

• A dual-body spray nozzle on each gutter broom

• An optional front spray bar

• An optional hopper spray bar

Depending upon where dust suppression is needed during a sweeping operation, the operator can direct waterto nozzles in any or all of these locations.

To operate the dust suppression system:

1. Start the auxiliary engine following the procedures outlined in Section, ‘AUXILIARY ENGINE START-UP.’

2. Turn on the water-pump electric drive motor by toggling its cab console control panel switch to ON. Theswitch is identified by the legend symbol shown below.

3. On the cab console control panel, locate the switch(es) for the nozzle(s) needed for spraying in hisoperation. Toggle the dust suppression switch(es) to ON.

4. Begin the sweeping operation.

5. When the sweeping operation is complete, toggle the dust suppression system switches to OFF.

NOTE: If certain nozzles are regularly used in sweeping operations, leave those nozzles ON when you turn offthe water system (by toggling the water-pump switch to OFF).

6. Toggle OFF the switch for the water-pump electric drive motor.

Use the right side steering only for sweeping, and never for travel exceeding 15 MPH.

4. SWEEPINGThe following assumes that this sweeper is equipped with dual steering, and is being used for a standardapplication, i.e., pavement and street cleaning. When driving to or from a job site, the driver should operate thetruck from the left side. It is both safer and easier to operate at highway speeds from the left side; right sideoperation should be reserved only for sweeping operations.

1. Stop the truck in a safe area and set the parking brake.

2. Take the truck transmission out of gear (putting it in neutral).



OPERATIONO

PER

ATIO

3. From the cab console control panel, toggle the warning light and safety flasher switches to the ON position.

4. Temporarily exit the cab to attach the ‘Slow Moving Vehicle’ emblem to the rear of the sweeper.

5. Realign the sweeper’s mirror for the right hand steering position.

6. Switch driving positions, being sure to toggle the dual steering switch so that the right steering position isempowered.

7. Begin sweeping operations.

Slow down for corners, parked cars, and when near protruding posts and other solidobstacles that could cause damage to the sweeper or truck.

Objects which are too large to be drawn up through the vacuum tube should be avoided or picked up by hand.Unless they are very large, these items can be deposited into the hopper through the side access door.

Sweeping through standing water or over wet pavement will not damage the sweeper. An advantage of thissweeper is that it will rapidly sweep up large amounts of water. This adds even more versatility to the machine.Under conditions where there is a large amount of water on the pavement, the hopper will need to be emptiedmore frequently.

5. DUMPINGGetting to the Dumpsite

Use the right side steering only for sweeping, never for travel exceeding 15 MPH.

If you are operating the sweeper from the right side and the dump site is NOT at the sweeping site, do thefollowing:

1. Stop the truck in a safe area and set the parking brake.


3. From the cab console panel, toggle the warning light and safety flasher switches to OFF.

4. Temporarily exit the cab to remove the ‘Slow Moving Vehicle’ emblem.

5. Realign the sweeper’s mirrors for the left hand steering position.

6. Switch driving positions, being sure to toggle the dual steering switch so that the left steering position isempowered.

Dump Operation Sequence

Check the overhead clearances before lifting the hopper. Never move the sweeper with thehopper in the raised position.

1. Drive to a firm level surface at the dumping site.

2. Set the parking brake.


4. If the auxiliary engine has been shut down for travel, restart the auxiliary engine following the proceduresoutlined in Section, ‘AUXILIARY ENGINE START-UP’.

Occasional Maintenance

The following table tells you where to look in the manual to find procedures for specific occasional maintenancetasks:

3. CLEANINGCleaning is an important part of any maintenance program because it extends the life of the sweeper byreducing rust and abrasion.

Additionally this gives the opportunity to inspect for any damaged or worn parts needing service orreplacement.

For a general description of cleaning procedures see Operation Section of Manual, ‘END OF SHIFT CLEAN-UP/MAINTENANCE.’

4. SWEEPER FLUID MAINTENANCEAuxiliary Engine Oil

Refer to your auxiliary engine Owner’s Manual for the manufacturer’s suggested oil type and oil changeschedule. To drain the engine oil pan, use the engine oil drain hose. This hose, which resembles the hydraulichoses, runs from the center of the oil pan, out the right side of the engine skid and is usually looped around tothe front of the engine skid for storage. By unscrewing and removing the JIC plug in the end of the hose, the oilmay be drained into a container. Be sure to dispose of the used oil properly, recycling it if possible.

NOTE: The small orifice of the hose will make the drain process slow. Make sure to allow plenty of time for thetask.

Hydraulic System

The hydraulic oil level should be maintained suchthat it is kept at the full mark as measured with thehopper down. Check by using the sight level gauge,which is located on the left side of the reservoir.Change the hydraulic oil and filter after the first 500hours of operation, then every 2000 hoursthereafter.

If the hydraulic fluid becomes cloudy, water hascontaminated the system and the hydraulic fluidneeds to be changed (after determining the sourceof the water contamination and correcting it). If thesweeping unit is operated in particularly dustyconditions, the hydraulic filters will need to bechanged more often.

For detailed maintenance procedures of thehydraulic system, See Maintenance Section‘HYDRAULIC SYSTEM MAINTENANCE.’

6. FILTERSBecause of the dusty conditions under which a sweeper operates, filters are considered a priority maintenanceitem. Failure to properly follow filter change schedules may result in poor performance or costly componentreplacement.

Auxiliary Engine Filters

The auxiliary engine has three filters: a fuel filter, anoil filter and a dual element air filter. At a minimum,all filters should be changed according to the enginemanufacturer’s warranty recommendations. Werecommend that the oil filter be changed more oftenif the sweeper is operated under unusually dustycircumstances.

The air filter has a built-in air restriction indicator.When the air filter becomes clogged and needsservice, a window on the air restriction indicatorchanges color. Depending upon the type of airrestriction indicator used, this color change may befrom clear to red, clear to yellow or yellow to red.The air restriction indicator is normally located on ornear the auxiliary engine’s air filter canister oroptionally by remote in the truck cab on the console.

Do not clean air filter with high pressure air.

Clean or change the air filter only when the air restriction indictor’s ‘Need to Service’ windowhas changed colors. Serious engine damage can occur as a result of air cleaner over-servicing.

For air filter change and service information, please see the Owner’s Manual for the auxiliary engine.

Hydraulic Tank Filters

The hydraulic tank employs two filters, a suction and a return, to remove foreign particles from the hydraulic oilthat might cause failure in the hydraulic system’s components. For detailed maintenance procedures on thesetwo filters, See Section, ‘IDYLLIC SUCTION STRAINER CLEANING/REPLACEMENT’ and Section,‘HYDRAULIC RETURN FILTER.’

Dust Suppression System Filter

Water filter maintenance is an important part in keeping the sweeper’s water system functioning properly. TheY strainer should be emptied and its strainer screen flushed and cleaned daily. However, the frequency of filtercleaning varies and largely depends on the purity of the fill source’s water.

For detailed maintenance procedures on the ‘Y’ strainer filter, See Section, ‘Y STRAINER CLEANING/REPLACEMENT.’

7. SealsIt is important that the sweeper’s seals on the fanhousing be kept in the best condition possible.These include the seals on the suction hose inlet,around the hopper’s inspection door opening andon the rear door. Pickup power is vacuum-dependent, so a tight seal can make a significantdifference in pickup ability. Maintain resilience bykeeping the seals well lubricated with a good gradeof petroleum-based jelly or grease.

Lubrication of the side inspection door seals isunnecessary.

For longer seal life, when the sweeper is parked foran extended period of time, leave the dump doorand all inspection doors open and raise the hopperseveral inches so their seals can regain their shape.

Eventually the seals will become worn or non-resilient and must be replaced.

Replacement:

1. Use a gasket scraper, putty knife orscrewdriver to remove the seal from itssweeper component. Get the metal surface asclean as possible. Be sure it is free of all dirt,old glue, and seal material.

2. Liberally apply a coat of weather-strip-typeadhesive onto the new seal and bodycomponent. Allow the adhesive to set up forseveral minutes (follow the adhesivemanufacturer’s instructions) and then put thenew seal in place.

8. HOPPERThe hopper is one of the central components of the A9 Monsoon sweeper. To ensure the longest possibleuseful lifetime, it is extremely important to clean it after each shift and to let it air dry with the hopper upwhenever possible.

8.1 Dump Door Latch AdjustmentThe hydraulic cylinders that operate the hopper dumpdoor and dump door latch mechanism are part of thesame hydraulic circuit. The circuit is designed tooperate the cylinders in sequence. When opening thedump door, first the latch cylinder retracts, openingthe latch fingers that secure the door shut, then thedump door cylinder retracts to open the dump door.When closing the dump door, the sequence isreversed; the dump door cylinder fully extends beforethe latch cylinder operates.

If for some reason, the extension/retraction sequenceof the two cylinders becomes reversed, a simpleadjustment to a flow control valve located on the latchcylinder can be made and will normally correct theproblem.

Adjustment:

1. Locate the latch cylinder behind the left rearmegaflop and attached to the bottom of thehopper floor.

2. Attached to the rear port of the cylinder is a flowcontrol valve. The flow control valve’sadjustment knob is locked in position by anAllen head set screw located on the side of theknob. Loosen the set screw so the knob may beturned.

NOTE: The needle valve may be used to restrict hydraulic fluid flow to the latch cylinder when closing thedump door. Hydraulic fluid, following the path of least resistance, extends the nonrestricted dump door cylinder.

3. Turn the knob clockwise 1/4 turn. This restricts fluid flow through the flow valve.4. Have a helper open and close the dump door while you watch. If, when the dump door closes, the

cylinders are still out of sequence (i.e., the latch cylinder extends before the dump door cylinder), repeatStep 3.

5. Once the proper setting has been achieved, tighten the se screw on the flow control valve’s adjustmentknob.

9. AUXILIARY ENGINEFor detailed information on the power module (auxiliary) engine, consult its Owner’s Manual. Engine parts forthe auxiliary engine must be purchased through your industrial engine dealer.

NOTE: Because of the nature and operation of a sweeping machine, it is recommended that servicing of thefilters, changing oil and other routine preventive maintenance functions be performed somewhat morefrequently than recommended by the manufacturer of the engine.

9.1 Auxiliary Engine Stub Shaft ReplacementThough instances of stub shaft failure are rare, as with any component, the stub shaft may, at some point, needto be replaced. Causes for stub shaft failure include; too much side-load created by a too tight drive belt,grooving or warping of the stub shaft by a failed bearing and stub shaft cracking or warping due to torquecreated by the sudden stop of the fan’s drive train. In addition, we suggest that the stub shaft be replacedwhenever the auxiliary engine is changed.

Replacement:

1. Remove the sweeper engine’s keys and/ordisconnect the battery cable to prevent the sweeperengine from being started accidentally.2. Follow the procedures outlined in steps 1 - 4 inSection ‘DRIVE BELT TENSION ADJUSTMENT’.3. Turn the jackscrew nuts so the engine skid ispushed toward the fan shaft.4. As the engine skid moves toward the fan shaft,the drive belt will become loose enough to be slippedfrom its pulleys.5. Remove the three 3/8” bolts and lockwashersfrom the stub shaft pulley bushing.6. Insert two of the 3/8” bolts into the two tappedholes of the stub shaft pulley bushing.7. Tighten the bolts evenly, alternating from one tothe other. This will push the pulley off the stub shaftpulley bushing.8. Remove the pulley and its bushing from the stubshaft.9. Remove the bearing plate from the end of theauxiliary engine bell housing. Inspect the plate forirregularities. If none are found, the bearing platemay be used again.10. Remove the old stub shaft from the end of theauxiliary engine.11. Clean the flywheel and replacement stub shaftusing lacquer thinner.12. Fasten the replacement stub shaft to the auxiliary engine using 60 ft. lbs. of torque on each bolt.13. Use a dial indicator and ensure that the stub shaft is in-line with the crankshaft. The stub shaft must be nomore than .008” off-center.NOTE: If the stub is more than .008” off-center, it should be replaced.

14. Place the replacement bearing onto the end of the shaft. Using a piece of pipe placed over the stub shaft’send, drive the bearing down the stub shaft until it rests against its seat.15. Slip the bearing plate down the stub shaft and onto the bearing.16. Bolt the bearing plate too the auxiliary engine.17. Slide the stub shaft pulley and its taper-lock bushing onto the end of the stub shaft.18. Insert the bolts through the taper-lock bushing onto the end of the stub shaft.

19. Check the alignment of the pulleys, using a string or straight edge, from the face of one pulley to the face ofthe other to determine whether the pulleys are in line with each other.20. If the pulleys are misaligned, back the stub shaft pulley off its bushing, move both in the proper direction foralignment, them retighten the bushing/pulley bolts.21. Inspect the drive belt for wear and replace it with a new one if needed.22. Slide the drive belt onto the stub shaft and fan shaft pulleys.23. Adjust the drive belt tension as outlined in Section, ‘DRIVE BELT TENSION ADJUSTMENT.’24. Replace the belt guard.

10. DRIVETRAIN COMPONENT MAINTENANCEThe following sections deal with adjustments, replacement and lubrication of mechanical portions of thedrivetrain.

10.1 DRIVE BELT TENSION ADJUSTMENOn the rear of the auxiliary engine is the belt whichdrives the fan shaft. Check the belt tensionperiodically. This is accomplished by pressing downon the belt halfway between the two pulleys. With 50-75 lbs. of pressure (the approximate equivalent ofvery firm pressure from on it from your thumb), thebelt should deflect about 1/4” - 3/8”. An average belt,over the course of its life, will stretch slightly and thebelt will need adjustment. This will be especially trueduring the first 50-75 hours of operation.

Adjustment:

The auxiliary engine, along with its engine skid, canbe moved in the direction of the fan shaft (to loosenor remove the belt) or away from the fan shaft (totighten the belt).

1. Remove the belt guard.2. Loosen (Do Not Remove) the bolt which holds each of the four outer corners of the engine skid to the top of

the power module platform.3. Locate the threaded rods known as jackscrews.NOTE: Before adjusting the jackscrews, it is always a good idea to mark the present position of the engineskid, both at the front and rear, on the power module platform. This will allow you to determine how far theengine skid has been moved and whether the center line of the auxiliary engine is still parallel with the fanshaft.

4. Loosen the jackscrews’ jam nuts.5. By running the adjustment nuts in or out, the engine skid may be moved toward or away from the shaft.

Alternate adjusting the jackscrew nuts front to rear so that movement of the engine skid is even and theengine skid does not become misaligned. If you turn the front jackscrew three revolutions, then turn therear jackscrew three revolutions.

6. When proper belt tension is achieved, re-thread the loose adjustment nuts tightly against their powermodule platform tabs. (If you’re adjusting the engine away from the fan shaft, these would be the inner

adjustment nuts; toward the fan shaft, these would be the outer adjustment nuts.) Tighten any loose jamnuts back against their respective adjustment nuts.

7. Tighten the four tie-down bolts at the corners of the engine skid.8. Start the sweeper engine. Squealing or abnormal vibrations indicate low belt drive tension. Adjust as

needed.9. Re-bolt the belt guard back into position.

10.2 Drive Belt ReplacementWith normal use, the drive belt will become worn. It is advisable to replace the drive belt when it shows signs ofwear, rather than waiting for it to break. This practice will help to ensure optimum sweeper performance andavoid downtime.

To replace the drive belt, reposition the sweeper engine. This can be accomplished by loosening the mountingbolts and jackscrews attached to the engine skid, as described in Section ‘DRIVE BELT TENSIONADJUSTMENT.’ Be sure to read the ‘DRIVE BELT TENSION ADJUSTMENT’ section before following theremoval/replacement outline in this section.

Before installing a new drive belt, always inspect the belt pulleys for nicks, burrs or excessive wear. Replacethe pulleys if such irregularities are found.

Removal:

1. Remove the sweeper engine’s keys and/ordisconnect the battery cable to prevent thesweeper engine from being started accidentally.

2. Follow the procedures outlined in steps 1-4 inSection ‘DRIVE BELT TENSION ADJUSTMENT.’

3. Turn the jackscrew nuts so the engine skid ispushed toward the fan shaft.

4. As the engine skid moves toward the fan shaft,the drive belt will become loose enough to beslipped from its pulleys.

Replacement:

1. Inspect the pulley grooves for burrs and other irregularities that may cause abnormal belt wear. Correct asrequired.

2. Slip the replacement belt into position.3. Tighten the jackscrew nuts so the engine skid is pulled away from the fan shaft.4. Continue to tighten until the belt has 1/2” deflection between the pulleys using 30 lbs. of pressure (roughly

the equivalent of pressing down on the belt with your thumb).5. Check the alignment of the pulleys, using a string or straight edge, from the face of one pulley to the face of

the other. This will allow you to determine whether the pulleys are in line with each other.NOTE: For slight misalignment, the pulleys may be repositioned on their respective shafts. If greateradjustment is needed than pulley repositioning can achieve, the entire engine/engine skid assembly must bemoved to obtain alignment. The slotted tie-down holes of the engine skid allow a limited amount of forward-back movement.

6. Once proper pulley alignment is achieved, run the jam nuts back against their respective jackscrew nuts.7. Tighten the four tie-down bolts at the corners of the engine skid.8. Start the sweeper engine. Squealing or abnormal vibrations indicate low belt drive tension. Adjust as

needed.9. Re-bolt the belt guard back into position.

10.3 FAN SHAFT BEARING LUBRICATIONThe two pre-lubricated bearings on the fan shaft should be re-lubricated after 250 hours of operation (check thesweeper engine’s hour meter and the lubrication chart). Use a lithium-based grease conforming to NLGINumber 2 consistency. It must be free from chemical impurities such as free acid and free alkali, as well asphysical impurities such as dust, rust, metal and other abrasive particles. This light-viscosity, low-torque greaseis selected because of its water-insoluble rust inhibitors and operating temperatures that make it chemicallyand mechanically stable. Its normal operating temperature range of -30° to +200° Fahrenheit is ideal forsweeper operations. However, it can operate intermittently at temperatures of up to +250° Fahrenheit,providing maximum bearing protection.

Always use a hand-operated grease gun to grease the bearing. Use only one pump of grease or until a smallbead forms around the bearing seal. This bead acts as an indicator of adequate lubrication and provides aprotective seal which prevents foreign material from entering the bearing where it would damage the races.There is generally a slight rise in operating temperature (10-30° Fahrenheit) after re-lubricating the bearing.This temperature rise will continue until the grease stabilizes in the bearing chamber.

Lubrication:

Do NOT get loose clothing, jewelry, etc., caught in rotating equipment.

1. Prior to lubricating, run the auxiliary engine in order to heat up the old grease. When the bearing grease haswarmed, turn the auxiliary engine off and remove the keys.

2. Using a hand-operated grease gun, slowly apply one pump of grease to the bearing (equivalent toapproximately 1/4 ounce of grease) or until a slight bead forms around the bearing seals.

NOTE: Never use more than one pump of grease, and do not grease the bearings more often than every 250hours of operation. Over-greasing the bearing will cause the bearing to overheat and fail.

Lubrication should never differ from the prescribed procedure or schedule. Bearing life is shortened by over-lubrication - either by greasing too frequently or too excessively.

10.4 Fan Shaft Bearing ReplacementWith proper lubrication, and under normal operating conditions, the bearings should last approximately 2500hours (check the auxiliary engine’s hour meter). Premature bearing failure is often due to improper lubricationprocedures. If bearing replacement is occurring more frequently than normal, you should review the bearinglubrication procedure outlined in this manual.

Bearing failure is accompanied by abnormal noise, vibration and/or the slinging of grease caused by rupturedbearing seals. Worn bearings should be replaced immediately to prevent damage to other sweepercomponents. The severing of the fan shaft, during the fan shaft bearing removal procedures necessitates areplacement fan shaft. Usually, accompanying drive belts, pulleys and bushings are also replaced. Thisensures proper performance and eliminates repetitive maintenance and downtime.

manual.19.Swing the hopper safety prop back into its travel position.20.Reconnect the engine’s battery cable, lower the hopper and check the operation of the sweeper.

11. FAN HOUSINGThe fan housing directs the flow of air from the fanto the sweeping head. To provide the maximumperformance from the fan, the fan housing and drivecomponents should be checked for wear regularly.When signs of wear occur on a component, replaceit as soon as possible.

FAN HOUSING



MAINTENANCEM

AIN

TENA

NC

E

11.1 Fan Housing CheckWhen air is drawn from the hopper into the fan housing, a small amount of fine dust is also pulled into the fanchamber. This fine dust wears the fan blades, fan housing liner, and the heads of the fan housing liner bolts.Over a period of time, the sandblasting effect of this dust will cause enough wear to these components thatthey must be replaced. Failure to replace them is dangerous and can be very costly, since a worn fan blade canbreak and damage the inside of the fan housing. Worn liner bolts may allow the fan housing liner to sag andcause damage to the fan as well as to its shaft and bearings. A worn liner permits the abrasive effect of theairstream to reach the walls of the fan housing, which is an expensive replacement item.

Inspection:

1. Raise the hopper and lower the safety prop into position.2. Remove the sweeper engine’s keys and disconnect the battery cable to prevent the engine from accidently 3. Remove the back plate.starting.4. Using a flashlight, inspect the fan blades, fan bushing, fan housing liner bolts and the fan housing liner for

wear.5. If no excess wear or abnormal wear is evident, replace the back plate, swing the hopper’s safety prop back

into its stored travel position and reconnect the battery cables.

11.2 Fan ReplacementIf a worn fan is causing reduced sweeping efficiency, it should be replaced promptly. The fan shaft bearingshave a life expectancy of roughly 2500 hours. When a fan replacement becomes necessary near the end of thebearing’s life expectancy, the bearings should likewise be replaced. Replacing both components will eliminatethe need to perform two, identical labor operations, and avoid downtime in close succession.

Exceptions to fan/bearing replacement:

• If you sweep in extremely sandy conditions, or do not use the sweeper’s water system, you may have to replace fans more often than bearings.

• If the proper bearing lubrication procedures aren’t followed, you may have to replace bearings more often than fans.

Disassembly:

1. Raise the hopper and lower the safety prop intoposition.


3. Remove the 3/8” bolts and washers from aroundthe back cover plate and lift it off.

4. Remove the 3/8” bolts and lock washers fromthe fan’s bushing.

5. Reinsert two 3/8” bolts into the tapped holes ofthe bushing. Tighten these bolts evenly. This willpush the fan off the bushing.

6. Use a gear puller to remove the bushing fromthe fan shaft.

7. Remove the fan from the fan shaft and fanhousing.

8. While the fan is out, check the rubber liner inside the fan housing. If signs of excessive wear are apparent,replace the liner by following the steps outlined in Section, ‘FAN HOUSING LINER REPLACEMENT.’Failure to replace the relatively inexpensive liner could result in having to replace the more expensive fanhousing later.

Replacement:

1. Inspect the end of the fan shaft. Remove anyburrs or rust from the shaft end with sandpaper.

2. Place the fan on the fan shaft and push it backinto the fan housing.

3. Inspect the bushing. If the bushing is notcracked or otherwise damaged, the originalbushing may be reused.

4. Apply an anti-seize agent to the tapered area ofthe bushing.

5. Slip the key into the bushing/fan shaft keyway.6. Position the fan bushing onto the fan shaft while

aligning it with the shaft key as well as the fan.Spread the bushing apart if necessary -remember, it will crack if it is overspread.

7. Drive the fan bushing onto the fan shaft untilapproximately 1/4” of the shaft extends from theface of the bushing. (Use a rubber hammer or awooden block and metal hammer to drive thebushing on.)

8. Insert the three 3/8” bolts with lock washers through the untapped bushing holes and into the tapped holesof the fan. Finger tighten the bolts. Do not tighten the bolts so as to secure the fan to the fan shaft.

9. Apply strip caulk, or a similar sealing agent, to the face of the fan housing.10.Install the back cover plate (it may be necessary to move the fan and its bushing further into the fan housing

before the back cover plate can be mounted). Before tightening the bolts, pull the fan back until it contactsthe back cover plate’s inlet ring. Using the available slack, center the cover plate’s inlet ring in the fan’sorifice. Feel around the perimeter of the inlet ring to confirm an even gap or fit. Tighten the cover plate bolts.

11. Move the fan back onto the fan shaft. A gap distance will have to be determined (see illustration). The idealgap distance is 1/4” from the cover plate orifice to the narrowest part of the fan’s orifice

12.Position the fan on the fan shaft, taking into consideration that, as the fan is tightened onto its bushing, it willtravel roughly 1/4” toward the cover plate’s orifice.

13.While holding the fan in position on the fan shaft, tap the fan bushing along the fan shaft and into the fan’shub.

14.When the fan bushing is snug inside thefan’s hub, insert the 3/8” bolts and tighten the fan onto the fanbushing. As the bolts are tightened and the fan is drawn onto the bushing, the fan should move 1/4” towardthe cover plate.

15.Turn the fan to determine if the two orifices rub as the fan rotates. If the orifices touch, mark the bushing’s present position on the fan shaft (so it may later be used as areference point). Remove the fan from its bushing and follow steps 12-16 to remount the fan further into thefan house.

If the orifices do not touch, proceed on to Step 16.

16.When the fan is properly mounted, swing the hopper safety prop into its stowed position and lower thehopper. Start the auxiliary engine and, again, listen for sounds of contact between the cover plate orifice andfan orifice. If none are audible, the unit is ready to sweep. If, however, sounds are detected, the hoppershould be raised and the fan readjusted.

11.3 Fan Housing Liner ReplacementTo prevent damage due to air-blast from the fan, a rubber liner is attached to the inside of the fan housing.Check the liner regularly for holes, tears or pitted areas, as well as for worn liner bolts. If the fan housing isexposed to direct wear because of a worn liner, the liner should be replaced. The rubber liner is relativelyinexpensive compared to replacing the fan housing.

12. SWEEPING HEADThe sweeping head is dependent upon forced airand vacuum to achieve debris pickup. Withoutproper maintenance and replacement of parts dueto normal wear, the sweeping head cannot providethe desired sweeping results.

The Schwarze A9 Monsoon may be equipped witha standard sweeping head or the optional Mechani-pneumatic Powerhood (for a detailed description ofeach sweeping head, please refer to IntroductionSection, ‘SWEEPING HEAD’). Many of themaintenance procedures outlined in the followingsections apply to both types of sweeping heads. Ininstances where procedures differ, the sections aredivided into ‘STANDARD’ and ‘MECHANI-PNEUMATIC POWERHOOD.’

12.1 Skid Plate Adjustment/ReplacementThe skid plate on the Schwarze A9 Monsoon’ssweeping head is designed for durability and lowmaintenance Tungsten carbide inserts in therunners ensure a long life to a part that must, by thenature of its job, endure extreme punishment.Replace the skid plate when its runner is 80% wornthrough.

Removal/Replacement:

1. Locate the skid plates on either side of thesweeping head. Note that studs, welded to thesweeping head, protrude through slots in theskid plates. The skid plates are held in placeagainst the head by the nuts and washers onthese studs.

2. With the sweeping head raised, remove the skidplate’s nuts and washers and set them aside forlater use.

3. Pull the old skid from the side of the sweeping head and replace it with the new skid plate.4. Remount the nuts and washers that were removed earlier. Screw them down against the skid plate, but do

not tighten them until the new skid plate is in the proper position.Remember: Whenever skid plate adjustment is necessary, the blast orifice must remain 2” to 2-1/2” from thesweeping surface. Less than 2”, and the air stream becomes choked down. More than 2-1/2” and the blastvelocity of the air striking the sweeping surface is lost.

Never adjust the skid plates to extend the life of the flaps. When the flaps can no longer maintain a satisfactoryseal, they should be replaced. Adjusting the skid plates may affect the sweeping efficiency due to the change inblast orifice-to-ground distance.

STANDARD SWEEPING HEAD SKID PLATE



MAINTENANCEM

AIN

TENA

E

Adjustment:

Do not adjust the skid plates so far up that the head’s blast orifice is less than 2” from thesweeping surface.

1. Raise the sweeping head and locate the skid plates on either side.2. Loosen the 5/8” nuts on each of the sweeping head skid plates.3. Slide each skid plate up or down its slots to achieve the required blast orifice-to-sweeping surface distance.4. Retighten the 5/8” nuts on each sweeping head skid plate.5. Lower the sweeping head and make sure that the skids are riding flat on the sweeping surface. Adjust as

needed.NOTE: Always adjust the exhaust with reference: The Intake Side.

Standard Sweeping Head Seasonal Adjustments

The sweeping head’s orientation to the sweeping surface may be manipulated by using some creative skidplate adjustments designed to maximize performance in various seasonal conditions. By adjusting the leadingends of the skid plates further up than their trailing ends, the pickup head can be set to minimize frontal area.This is often preferable during heavy cleanup periods, such as in the Spring cleanup season. Adjustment in thismanner provides a faster channel of air/debris mixture and less distance that the debris must move.

Just as making the frontal area shorter increases heavy sweeping performance, making the frontal area tallerincreases sweeping performance in lighter debris. This adjustment may be accomplished by performing theopposite of the above procedure, i.e., adjust the skid plates’ trailing ends up more than their leading ends. Thisis especially helpful during the Fall when leaves must be swept.

Please note that these adjustments should be made only under extreme conditions. In all other times, thenormally recommended adjustments will usually suffice. Prolonged usage with the above adjustments willrequire flap replacement when readjustment to normal conditions is made.

12.2 Sweeping Head Tension Spring AdjustmentNear the four corners of the sweeping head are thesweeper head tension springs. These help thesweeping head ‘float’ by relieving some of its weightfrom the sweeping surface. If the springs areadjusted correctly, by grasping the front corner ofthe sweeping head with your hand, you should beable to move it slightly with roughly 40 lbs. ofupward lift. Although operator preference varies,this is normally the optimal setting. Less tensionshortens runner life. More tension creates apossibility that the head may bounce on irregularsurfaces, which will break the suction seal.

Fine Adjustment:

1. Locate the eye bolt that connects the head spring to the frame.2. Loosen or tighten the nut on the end of each eye bolt to raise or lower the head.Coarse Adjustment:

1. Raise the sweeping head.2. Unhook the chains from the springs or remove the 5/16” bolts that hold the spring chains to each side of the

head.3. Increase or decrease the number of chain links between the head retainers and the ends of the head

springs as needed.NOTE: If adjusting the head spring tension does not correct the problem of excessive runner wear, the problemmay be caused by bent or uneven drag arms.

12.3 Sweeping Head Flap Check/ReplacementInspection:

The sweeping head is dependent upon forced air movement to provide proper sweeping results. The flapsunderneath the sweeping head must maintain the air stream as it moves across the head to the vacuum tube.

When new, the sweeping head flaps will extend past the bottom of the skid plate. With use, they will wear untilthey hang straight down and lose contact with the ground. When this occurs, it is time to replace the flaps.

Do not attempt to extend the life of the flaps by adjusting the skid plates. The head’s blastorifice must never be less than 2” from the sweeping surface.

Standard Sweeping Head Only Sweeping Head Removal:

1. With the sweeping head raised, unhook the chains from the springs or remove the 5/16” bolts that hold thespring chains to each side of the head.

2. Lower the sweeping head and loosen the lower hose clamps on each side of the sweeping head.3. Remove the lower ends of the intake and exhaust hoses.4. Remove the 3/8” bolts that hold the sweeping head lift cylinder chains to each side of the sweeping head.5. Disconnect the water hoses which run down the drag arm from the hose barb of the first in-line spray nozzle

on the sweeping head, and the hose barb of the intake tube.6. Remove the 7/8” drag arm bolts.7. Unbolt the gutter brooms’ center drag flap from the front of the head.8. Slide the sweeping head out from underneath the truck and flip it over.

Flap Replacement:

On the underside of the head, there are four flaps ofdiffering sizes. The positioning of each flap isdesigned to produce the maximum performancefrom the sweeping head. To ensure proper flapplacement, replace one flap at a time.

1. Remove the 1/4” bolts which hold the metalbacking strips and the flap to the sweeping head.

2. Use the worn flap as a template by placing it ontop of its proper replacement and mark the endsand holes with spray paint.

NOTE: Schwarze Industries OEM replacementflaps are pre-punched. The small intake flap willneed replacing less often than the other sweepinghead flaps. However, when replacing it, follow thesame flap replacement procedures.

Check the rubber flaps that are corded, and be surethey are not turned front-to-back. The cords shouldbe on the rear side of the flap.

3. Cut the new flap to length with a utility knife, and drill or punch the mounting holes.4. Install the new flap and metal strips using the original hardware.While the sweeping head is upside down, check the blast orifice for objects or blockage in the opening andclean as needed. Check the blast orifice opening for damage or deformity from impact of objects on thesweeping surface. The blast orifice opening should be approximately” 1/8” - 1-1/4”.

Reinstalling The Sweeping Head:

Turn the sweeping head upright and replace it under the truck in the reverse order used in the ‘Sweeping HeadRemoval’ section outlined previously. With the sweeping head raised, the skid plates may be adjusted (SeeSection, ‘SKID PLATE ADJUSTMENT/REPLACEMENT’) to provide the proper blast orifice-to sweepingsurface distance of 2” to 2-1/4”. Even with the sweeping head adjusted to the proper height, the new flaps willstill hang below the bottom of the runners on the skid plates. Lower the sweeping head onto a level surface andcheck the skid plate adjustment. If the skid plate adjustment seems correct, start the sweeper and check thehead flaps for proper sealing and adequate pickup.

Mechani-Pneumatic Powerhood Only Sweeping Head Removal:

1. With the sweeping head raised, unhook the chains from the springs or remove the 5/16” bolts that hold thespring chains to each side of the head.

2. Lower the sweeping head and loosen the lower hose clamps on each side of the sweeping head.3. Remove the lower ends of the intake and exhaust hoses.4. Disconnect the wires powering the actuator which raises and lowers the scroll broom. This may be done by

detaching the plug roughly 10” from the actuator.NOTE: Locate the hydraulic hoses that run down to the left top of the sweeping head. Note the two fittingswhere the hoses enter the top of the sweeping head. These are quick disconnect fittings.

5. Lift the collars of each fitting to release the quick disconnects of the scroll broom’s hydraulic hoses.6. Remove the 3/8” bolts that hold the sweeping head lift cylinder chains to each side of the sweeping head.7.

12.4 Setting The Blast OrificeStandard Sweeping Head with Optional Adjustable Blast Orifice

The standard sweeping head is equipped with anadjustable blast orifice. This feature allows the widthof the blast orifice to be set to operator preference.The blast orifice is set at the factory at a width of 1-1/8”. However, some operators prefer it a little wider(creating less blast force) or narrower (creatingmore blast force). It should be noted that too muchvariance from the standard 1” width will reducesweeping efficiency either by reducing the blastforce striking the sweeping surface or by restrictingthe flow of air in the regenerative sweeper’s closedloop.

1. Locate the two jackscrews along the rear edgeof the sweeping head.

2. To adjust the blast orifice width, turn the hexhead of the jackscrews clockwise to open theorifice and counterclockwise to narrow it.

Mechani-Pneumatic Powerhood

The adjustable blast orifice is standard on the Mechani-pneumatic Powerhood SM and is set at the factory to awidth of 1-1/4”. However, some operators prefer it a little wider (creating less blast force) or narrower (creatingmore blast force). It should be noted that too great a variance from the standard 1” width will reduce sweepingefficiency either by reducing the blast force striking the sweeping surface or by restricting the flow of air in theregenerative sweeper’s ‘closed loop.’

1. Locate the two knobs on either side of the rear of the sweeping head.2. By turning the knobs clockwise, the blast orifice is widened. By turning them counterclockwise, the blast

orifice becomes narrower.

12.5 Scroll Broom Pattern CheckMechani-Pneumatic Powerhood Only

The bristle-to-sweeping surface strike pattern of thePowerhood’s scroll broom should be 1” to 1-1/2”wide.

1. Drive the sweeper to a flat area of payment.2. Lower and run the Powerhood and its scroll

broom following the procedures outlined inSection 3.2.4, ‘Sweeping Head Operation.’ Allowthe broom to run in the same spot forapproximately 1 minute.

3. Raise the Powerhood and drive the sweeperclear of the test pattern area.

4. Inspect the wear pattern of the broom on thepavement. If the pattern is less than 1” or morethan 1-1/2”, the scroll broom should be adjusted.



MAINTENANCEM

12.6 Scroll Broom AdjustmentMechani-Pneumatic Powerhood Only

The scroll broom pattern may be adjusted by the manipulating the actuator that raises and lowers the scrollbroom.

1. Locate the actuator tower on the top left side of the sweeping head.2. Note that the actuator, within the actuator tower, passes through a pipe sleeve whose base contains a

jackscrew.3. By turning the jackscrew, the actuator may be raised or lowered. Lowering the actuator creates a wider

scroll broom strike pattern. Raising the actuator narrows the strike pattern.

12.7 Scroll Broom ReplacementMechani-Pneumatic Powerhood Only

Eventually the scroll broom will wear until the bristles are 2-1/2” to 3” long at which time the broom must bereplaced. The broom may be replaced from beneath the sweeper without removal of the Powerhood.

NOTE: Before beginning scroll broom replacement, be sure the Powerhood is raised against the upstops andthe scroll broom, within the hood, has been lowered.

1. Remove the access door from the top right of the Powerhood. This will allow you access into the chamberlocated beneath it. Within the chamber lies another access door held in place by five knobs.

2. Unscrew the knobs and remove the L-shaped access door.3. The removal of the L-shaped access door exposes the right end of the scroll broom and its lift arm.

Thoroughly wash both the scroll broom and its lift arm.4. Locate the bolts that holds the right side bearing and idler arbor in place.5. Remove the bolts to release the bearing and idler arbor. 6. Pull the bearing and idler arbor from the end of the scroll broom.7. Pull the scroll broom toward the right side of the sweeping head to detach it from the hydraulic motor hub

inserted into the scroll broom’s left end.8. Slide the scroll broom out the front of the sweeping head.9. Reverse the procedure to install the replacement scroll broom.

12.8 Sweeping Head Hose Replacement1. Unscrew the band clamps at the top and bottom of the hose to be removed.NOTE: If the hose has been on for an extended period, it may take some manual wiggling to get it loose.Insertion of a screwdriver between the hose and the housing will help.

2. Once loose, slide off the hose, and replace it with a new one.3. Put the band clamps back in place and tighten them.

12.9 Sweeping Head Hose RotationThe high pressure air stream will wear the insides of the sweeping head’s hoses. To extend the life of the intakeand exhaust hoses, periodically (3 or 4 times a year) rotate each hose 1/4 turn. A torn intake or exhaust hosewill cause a decrease of vacuum power. Torn hoses may be temporarily repaired with duct tape untilreplacements can be installed.

1. Loosen the hose clamp on both ends of the hose.2. Turn the hose 1/4 turn and retighten the clamps.

13. Gutter BroomThe following sections deal with adjustments and replacement of mechanical portions of the gutter broom. Forthe gutter broom hydraulic system maintenance, follow the procedures outlined for the gutter broom in Section‘MAINTENANCE SCHEDULES’ and in Section, ‘SWEEPER FLUID MAINTENANCE.’

13.1 Gutter Broom Pattern CheckA broom pattern is the pattern of marks left on asweeping surface after the sweeper has passedover it. You should check this pattern to verify thefollowing conditions:

• That the broom is reaching the sweeping surface

• That the left-broom pattern is a 9-to-1 o’clock contact

• That the right-broom patter is an 11-to-3 o’clock contact.

Before you begin this procedure, you shouldunderstand how 3-position toggle switches areoperated from the cab console. See Section‘CONSOLE CONTROLS.

Inspection:

1. Move the sweeper to a flat asphalt or concretesweeping surface and start the auxiliary engine.

2. On the cab console control panel, toggle thegutter broom switch to RUN.

3. Allow the broom to run in contact with thesweeping surface for a minute or so.

4. On the cab console control panel, toggle thegutter broom switch to OFF.

5. On the cab console control panel, toggle thegutter broom switch to UP.

6. Reverse the sweeper several feet to expose thesurface just swept.

7. Turn off the truck engine and set the parkingbrake.

8. Get out of the cab and inspect the broom pattern (the worn area on the sweeping surface). The left-broompattern should be a 9-to-1 o’clock contact with the surface. The right-broom pattern should be a 11-to-3o’clock contact with the surface. If either pattern is irregular, the corresponding gutter broom needsadjustment. Follow the procedures outlined in Section, ‘GUTTER BROOM TILT ADJUSTMENT’ and/orSection, ‘GUTTER BROOM DOWN PRESSURE ADJUSTMENT.’

13.2 Gutter Broom Tilt AdjustmentA gutter may be so deep that the broom cannot reach the surface. In this case, broom-to-surface contact canbe improved by adjusting one or both axis (the side-to-side and forward/rearward tilt) of the gutter broom.

If the gutter broom is not throwing debris into the sweeping head path, broom pattern can be improved byadjusting one or both axis (the side-to-side and forward/rearward tilt) of the gutter broom.



MAINTENANCEM

AIN

NOTE: To prevent gaps in the overall broompattern, through which debris can pass, always besure the gutter broom pattern overlaps the path ofthe head.

CAUTION: Do not adjust the skid plates so far upthat the head’s blast orifice is less than 2” from thesweeping surface.

Forward / Rearward Tilt

Forward/rearward tilt is controlled by a turnbuckle running between the broom arm mounting bracket and thetop of the broom motor mount.l This turnbuckle must be adjusted manually.

Adjustment:

1. With the auxiliary engine stopped, turn the auxiliary engine key switch to ON, but do NOT start the engine.Toggle the gutter broom cab console control switch to RUN.

2. Locate the large turnbuckle located between the gutter broom mounting bracket and the gutter broom motormount.

3. Loosen the jam nut on the turnbuckle.4. Insert a large screwdriver or wrench into the center of the turnbuckle to use as leverage.5. Choose one:• To lower the nose of the gutter broom disc, lengthen the turnbuckle by turning the center clockwise.• To raise the nose of the gutter broom disc, shorten the turnbuckle by turning the center counterclockwise.6. Run the jam nuts tight against the turnbuckle to lock the readjustment.

Side-To-Side Tilt

Side-to-side tilt is controlled by the broom arm’s small turnbuckle running between the pivot (connecting thebroom arm to one side of the broom motor mount) and the rear of the broom arm. This turnbuckle must beadjusted manually.

The gutter broom should be extended to its normal operating position and stopped beforeperforming the side-to-side tilt adjustment. NEVER adjust the gutter broom while its disc isrotating.

Adjustment:

1. Start the auxiliary engine by following the procedures outlined in Introduction Section, ‘AUXILIARY ENGINESTART-UP.’

2. Run the gutter broom to its extended sweeping position following the procedures outlined in IntroductionSection, ‘Gutter-Broom Operation.’

3. Toggle the gutter broom switch to the center neutral position to stop gutter broom disc rotation.4. Locate the small turnbuckle located in the gutter broom arm.5. Loosen the jam nut on the turnbuckle.6. Insert a large screw driver or wrench into the center of the turnbuckle to use as leverage.

7. Choose one:• To increase the tilt of the gutter broom disc, lengthen the turnbuckle by turning the center clockwise.• To decrease the tilt of the gutter broom disc, shorten the turnbuckle by turning the center counterclockwise.8. Run the jam nuts tight against the turnbuckle to lock the readjustment.

NOTE: An optional feature, the broom-tilt-actuator, allows control of the gutter broom disc angle with a switch-activated cylinder that replaces the small turnbuckle.

Extension or retraction of the cylinder on the gutter broom arm causes the broom disc to tilt.

13.3 Gutter Broom Down-Pressure AdjustmentGutter broom down-pressure can be defined as the total weight of the following:

• The large hydraulic broom motor• The heavy plate metal used to construct the broom, disc, hydraulic-motor mount and broom armsThe maximum amount of down-pressure cannot exceed the total amount of broom weight resting on the broombristles.

Optimum down-pressure yields good sweeping performance appropriate to the current surface. Lighter debrisrequires less down-pressure; heavier material, such as soil or millings, require more digging pressure from thebroom.

Never adjust the gutter broom when the gutter broom is running.

Adjustment:

1. With the broom in the up position, locate the nut holding the eyebolt to the motor-mount angle bracket.2. Thread the nut all the way out to the end of the eyebolt. 3. Remove or add chain links as desired between the eyebolt and spring.4. Screw the eyebolt nut about 1-1/2 inches up the eyebolt. 5. Start the auxiliary engine.6. Lower and run the gutter broom.7. As the broom runs, observe the bend in the broom bristles to determine whether down-pressure should be

increased or decreased. 8. Stop the broom.9. Turn the auxiliary engine OFF.10.Choose one:• If down-pressure should be INCREASED, loosen the eyebolt nut by threading it further down the eyebolt.• If down-pressure should be DECREASED, tighten the eyebolt nut by threading it further up the eyebolt.

13.4 Gutter Broom Extension Spring AdjustmentThe gutter broom extension spring controls the gutter broom arm extension speed and travel. Located to theoutside of the gutter broom arm, this spring is connected to the gutter broom mounting bracket by a chain atone end. The spring’s other end is attached to a large eyebolt fastened to the gutter broom motor mount. Tostart a sweeping operation, the extension spring extends the broom to its working position. When the broom isretracted, however, the tightening spring works in combination with the upward and inward pull of the cylinderto raise the gutter broom arm off the sweeping surface.

The gutter broom extension spring may need adjustment when:

• The broom doesn’t fully extend during operation• Travel speed is too slowYou control the gutter broom arm extension speed and travel by adjusting:

• Extension spring tension• Attitude of the chain

Never adjust the extension spring when the gutter broom is running.

Adjustment:

1. With the broom in the up position, locate the extension spring.2. Locate the row of slots in the gutter broom mounting bracket’s outer plate.3. Perform one of the following to change the attitude of the chain:• To DECREASE chain attitude, move the chain to a slot closer to the outer plate.• To INCREASE chain attitude, move the chain to a slot further away from the outer plate. 4. Perform on of the following to adjust extension spring tension:• To INCREASE tension, remove links from the chain and/or adjust the eyebolt on the gutter broom motor

mount.• To DECREASE tension, add links to the chain and/or adjust the eyebolt on the gutter broom motor mount.

13.5 Gutter Broom Hydraulic AdjustmentThe only hydraulic adjustment that may be necessary concerns return speed. Return speed is controlled by aflow control cartridge valve on a small valve block, fastened to the main valve.

You open or close this flow control cartridge valve to adjust hydraulic return speed, turning it clockwise to slowthe return speed and counterclockwise to increase the return speed.

Gutter broom hydraulic speed may need adjustment when the gutter broom:

• Does not retract.• Retracts too fast.• Retracts too slowly.

Adjustment:

1. Start the sweeper and run the gutter broom for about 5 minutes.2. Check the sight gauge on the hydraulic tank. 3. Choose one:• If hydraulic-fluid temperature has reached 80° degrees, turn off the sweeper and the gutter broom.• If hydraulic-fluid temperature has NOT reached 80° degrees, continue to run the sweeper and gutter broom

until it does, then shut them off.4. Locate the flow control cartridge valve on the small valve block fastened to the gutter broom mounting

bracket. The flow control cartridge valve protrudes from the bottom of the valve block.5. Loosen the jam nut that secures the stem of the flow control cartridge valve.6. Restart the sweeper and broom.7. Run the broom at normal RPM. 8. Observe the return speed as you lower and raise the gutter broom.



MAINTENANCEM

AIN

TENA

NOTE: Return speed should be between 1-1/2 and 3 seconds. A slight turn of the flow control cartridge valvewill result in a great change in the retraction speed.

NEVER adjust the flow control cartridge valve when the gutter broom is turning. Always stopor retract the gutter broom before attempting to adjust the control flow cartridge valve.

9. Choose one:• If return speed is too fast, decrease the flow by inserting an Allen wrench into the end if the valve’s stem

and turning clockwise.• If return speed is too slow, increase the flow by inserting an Allen wrench into the end if the valve’s stem

and turning counterclockwise.10.When return speed is between 1-1/2 and 3 seconds, run the jam nut back against the valve’s main body to

secure the valve stem in place.11.Turn off the sweeper and broom.

13.6 Gutter Broom Cylinder Adjustment/ReplacementNOTE: Do not attempt to adjust or replace the gutter broom cylinder while the broom is running.

5. Disconnect the two hoses from the cylinder.

Replacement

1. Connect the two hoses to the replacement cylinder.2. Use the two bolts (previously set aside) to install the replacement cylinder.

13.9 Gutter Broom Bristles ReplacementGutter broom bristles should be replaced when they are worn to approximately 8 inches in length. When gutterbroom bristles are allowed to wear shorter then 8 inches, the bristles gradually become too stiff and loose theirability to flick debris.

Gutter broom bristle replacement options vary. Bristle segment bases may be fabricated from wood, aluminum,or plastic; their bristles, available in a variety of different gauges and lengths, may be fabricated from metal orplastic.

1. With the gutter broom in the raised position, locate the most accessible gutter broom bristle segments.2. Remove the three bolts that hold the first gutter broom bristle segment to the gutter broom disc, and set

them aside.3. Depending upon the type of replacement gutter broom bristle segment you use, choose one of the following

to secure the segment to the gutter broom disc:• Position the first replacement gutter broom bristle segment and replace the three bolts holding it to the

gutter broom disc.• Press all attachment nuts into place on the bottom the gutter broom-bristle segment base. Position it under

the gutter broom disc, then bolt it in place.4. Repeat steps 2 and 3 for other accessible gutter broom bristle segments.5. Start the auxiliary engine.6. On the cab console control panel, toggle the gutter broom switch to RUN.7. Stop and raise the disc when other gutter broom bristle segments are accessible for replacement.8. Repeat steps 2 through 6 to expose and replace all gutter broom bristle segments needing replacement.

14. HYDRAULIC SYSTEM MAINTENANCENOTE: The tank may be isolated from the rest of the system by use of a valve, located next to the hydraulictank in the system supply line. If, for some reason, the hydraulic system needs to be opened, the valve may beclosed and the draining of the tank for system maintenance purposes will be unnecessary.

We recommend the maintenance listed in the following table.

14.1 Hydraulic Tank Fill-UpFill-Up:

1. Locate the hydraulic tank on the left side of the sweeper between the power module uprights.2. Examine the hydraulic fluid sight-level gauge located on the side of the tank. The hydraulic fluid within the

glass face of the gauge allows you to determine whether the tank needs filling.

NOTE: The fluid level should register at or about the high mark.

3. If the tank needs filling, locate the fill opening on top of the hydraulic tank.4. Remove the cap.5. Use a funnel to fill the hydraulic reservoir to the desired level with one of the following:• Shell Tellus 68 hydraulic fluid• Citgo 68 hydraulic fluid• An equivalent 22-weight (SAE) fluid

NOTE: 30-weight (SAE) fluid is required for any system operating with an ambient fluid temperature greaterthan 100ºF.

6. Replace the cap.

14.2 Draining the Hydraulic TankTank Draining:

1. Locate the drain hose attached to the bottom of the hydraulic tank. This drain hose exits the bottom of thetank, and is usually stored between the uprights and engine, or run down the back of the power modulebeside the fan house.

2. Place a 25 gallon capacity container on the ground, positioning it below the drain.3. Remove the JIC plug from the end of the drain hose.

14.3 Hydraulic Fluid ChangeHydraulic Fluid Should Be Changed When:

• Maintenance records show that the new sweeper has completed its first 500 hours of operation• Thereafter, maintenance records should show that the sweeper has been operated 2,000 hours since its

last hydraulic fluid change. • If the hydraulic fluid becomes cloudy, water has contaminated the system. It should be changed and

flushed.

NOTE: If the hydraulic oil contains water, be sure to determine the source of the water contamination beforechanging and flushing the hydraulic oil.

Fluid Change:

1. Drain the hydraulic tank by following the procedures outlined in Section, ‘DRAINING THE HYDRAULICTANK.’

2. Refill the hydraulic tank with one of the following;• Shell Tellus 68 hydraulic fluid• Citgo 68 hydraulic fluid• An equivalent 20-weight (SAE) fluid.

NOTE: 30-weight (SAE) fluid is required for any system operating with an ambient fluid temperature greaterthan 100ºF.

3. Choose one:• If you intend to reuse the hydraulic fluid just drained, filter it.• If you do not intend to reuse the hydraulic fluid just drained, transfer it to a closed container approved by

local, state and federal environmental agencies and deliver it to the appropriate disposal site.

14.4 Hydraulic Suction StrainerNOTE: Replace or clean the suction filter after the first 500 hours of operation, then every 2000 hoursthereafter.

Replacement:

1. Drain the hydraulic tank following the procedures outlined in Section, ‘DRAINING THE HYDRAULIC TANK.’2. Locate the suction filter. Its large bushing-like head may be seen protruding from the suction line’s tank

flange located near the bottom of the hydraulic tank. 3. Remove the suction hose and its fittings from the center of the strainer.4. Unscrew the strainer from the hydraulic tank.5. Examine the suction strainer.6. Choose one:• If the strainer is clogged, clean it with an approved cleaning solvent.• If the strainer is damaged, replace it with an S-5 strainer.7. Screw the cleaned or replacement strainer into the tank.8. Reattach the hose and its fittings to the center of the strainer.

14.5 Hydraulic Return FilterNOTE: Change the return filter after the first 500 hours of operation, then every 2000 hours thereafter.

Replacement:

1. Locate the return filter.2. Unscrew the old canister from the filter head.3. Fasten the replacement filter canister to the filter head.

14.6 Hydraulic System Pressure Check/AdjustmentThe hydraulic system runs at a MAXIMUM relief hydraulic pressure of 2500 PSI. Only when the hydraulicsystem is under maximum load, such as when the head is against the upstops and continues to be raised, willthe system reach this PSI. Normally, the operating hydraulic pressure falls well below this.

Hydraulic Pump Pressure Check

When hydraulic cylinders and hydraulic motors will not function properly, there may be a hydraulic pumppressure problem. Before making any adjustments, always check the electric and hydraulic systems for looseconnections. Check the hydraulic fittings and hoses for leaks. Also, check the fluid for contamination andproper fill level. Increasing the pump pressure due to loose fittings, leaking hoses, contaminated fluid or aclogged filter can cause damage to the pump and other sweeper components. If, after making all possiblehydraulic checks, you still believe there is a problem with low fluid pressure from the pump, two people caneasily verify the pump’s fluid pressure. The procedure is as follows:

Pressure Verification:

1. Use a gauge to check the pump’s outputpressure. A convenient test nipple, located onthe pressure port fittings of the hydraulicmanifold, has been provided for easy pressuretesting. Attach a pressure gauge (able tomeasure at least 3000PSI) to the test nipple.

If the unit is equipped with the Mechani-PneumaticPowerhood, SM there will be a test nipple on thepressure port fittings of both manifolds.

2. Start the auxiliary engine and throttle up toapproximately 2000 RPMs.

3. Have a helper hold the gutter broom switch inthe ‘raise’ position and continue to hold theswitch in this position even after the gutterbroom is fully raised.

If the unit is equipped with the Mechani-PneumaticPowerhood,SM test the pressure of the single stagemanifold by holding the sweeping head in the ‘raise’position and continue to hold the switch in thisposition even after the sweeping head is fullyraised.

4. Check the pressure gauge; it should read 2500 PSI while the switch is being held on. When the switch isreleased, the pressure gauge reading should change to about 800 PSI.

5. If the pressure gauge reading is considerably different, you may need to adjust the manifold’s pressurerelief valve.

Pressure Relief Valve Adjustment

1. Locate the relief valve. It is screwed into the face of the manifold block.If the unit is equipped with the Mechani-Pneumatic Powerhood, SM a relief valve will also be protruding fromthe bottom of the separate single stage manifold block.

2. Loosen the relief valve stem’s jam nut. Screw the relief valve stem in to increase the fluid pressure, and outto decrease it.

NOTE: Turn the adjustment stem no more than 1/8 of a complete revolution at a time.

14.7 Directional Valve OverrideIn the hydraulic system, fluid flow direction is used to control the various hydraulic functions. It is the task of thedirectional valve to determine flow direction. If the directional valve is faulty and unable to reverse the hydraulicfluid flow, the directional valve’s hydraulic function cannot operate properly.

Override Check:

1. Locate the directional valve attached to the manifold block on the top left side of the power module.

NOTE: Two plugs attach electrical wires to the solenoid at either end of the directional valve. Each plugcontains a small light that illuminates whenever that solenoid is electrically activated.

2. With the auxiliary engine running, toggle the in-cab console control panel switch that controls the hydraulicfunction for that particular directional valve. One of the two lights should illuminate, indicating power is being supplied to that side of the directionalvalve. If neither light operates, the directional valve is not receiving power and the problem is electrical.

If the directional valve lights operate when the incab console control panel switch is toggled, the problemmay be within the directional valve.

3. On either end of the directional valve is a small hole, usually about 1/8” in diameter. With the auxiliaryengine running, insert a small nail or small Phillips screwdriver to insert into the holes (one at a time) ateither end of the directional valve to manually override the directional valve. There is an initial easy push ofthe plunger, then a greater amount of pressure must be used to overcome the spring. If this procedurecorrects the hydraulic function problem, then the directional valve is faulty and should be repaired orreplaced.

15. DUST SUPPRESSION SYSTEM MAINTENANCEFor dust suppression during sweeping operations, water flows from the water reservoirs and through the ‘Y’strainer and the hydraulically-driven water pump. Then, it goes through the water manifold and hoses to thespray nozzles.

Depending upon where dust suppression is needed, water may be directed from the sweeper console to any orall of the following:

• The nozzles in the front spray bar• Gutter broom dual-body spray nozzles• Hopper nozzles on the intake tube• Nozzles placed at the four corners of the head

Water being drawn from the water reservoir to the water pump passes through the Y strainer screen, trappingand preventing debris from reaching the rest of the dust suppression system. Because the Y strainer trapsdebris that could clog spray nozzles, it must be cleaned daily.

We recommend the maintenance listed in the following table:

15.1 Water Reservoir RefillTo refill the water reservoir, use the 25-foot hose, stowed in the tool box on the sweeper.

Replacement:

1. Turn on the hydrant and allow the water to run for a short interval so any rust and/or sediment trapped in thewater line can be cleared.

An uncleared water line can introduce debris to the sweeper’s water system, necessitatingfurther cleaning and exposing the sweeper to possible damage.

2. Remove the 2-1/2” hydrant hose from its storage rack beneath the right side of the water reservoir tray andattach its end to the hydrant. The opposing hose end is attached to the pipe feeding the air-gapped fillopening of the reservoir.

3. Allow the reservoir to fill until water gushes from its overflow.

15.2 Water Manifold Solenoid CleaningThe water manifold solenoid should be cleaned when one of the following conditions exists:

• Water leaks (perhaps even sprays weakly) from nozzles for that solenoid, indicating that the solenoid does not fully close.

• Little or no water flows from the nozzles for that solenoid, indicating that the solenoid does not fully open.Before you use the following procedures, thoroughly check the following:

• Electrical circuit related to the faulty valve• Possible clogged nozzles

Never use ANY type of cleaning fluid to clean the solenoid valve plunger assembly or seals.

Make sure all electrical current and pressures are OFF before you begin this procedure.

Cleaning:

1. Shut OFF all electrical current and pressure.2. Remove the nut at the top of the solenoid valve.3. Remove the name plate, coil and housing from

the body.4. Choose one:• If the valve is NOT leaking from the seat and

the plunger does NOT stick in the energized position, the problem is electrical.

• If the valve IS leaking from the seat or the plunger DOES stick in the energized position, proceed to the next step.

5. Use the Peter Paul wrench (attached to the 3-ring binder for this manual) to remove the sleeveassembly.

6. Examine the soft inserts in the plunger forevidence of dirt and/or wear.

7. Examine the inside of the sleeve assembly forevidence of dirt and/or debris.

8. Choose one:• If the inserts show excessive wear, you must

replace the plunger.• If the valve emits a loud buzzing noise, examine

both the inside of the sleeve and upper portion of the plunger and remove all foreign matter.

Be very careful not to damage the sleeve seat or plunger face. If you mar either surface, youmust replace the entire sleeve and plunder assembly.

If you must remove the entire valve assembly from the line, be very careful that no foreignmatter gets into the valve. During reconnection, pipe-thread chips in either the seat or thesoft inserts will cause valve malfunction.

Order replacement parts bearing the valve number, voltage, and frequency specified on thename plate.

9. After cleaning or replacing parts, verify that both the flange seal and the return spring are in place.10.Loosely screw the sleeve assembly into the body.

Do NOT connect the valve to the electrical circuit.

11. Before you tighten the sleeve assembly to the body, choose one:• If the valve has a sleeve port, cap the port and apply pressure to the port leading to the body chamber.• If the media is air or gas, apply water to the joint and watch for air bubbles.12.Reattach the name plate, coil, and housing to the body.13.Carefully tighten the nut at the top of the solenoid valve.

Excessive tightening of the nut can cause unnecessary strain on either the sleeve assemblyor the coil under the housing.

14.Restart electrical current and pressure.

15.3 ‘Y’ Strainer Cleaning/ReplacementThe dust suppression system ‘Y’ strainer should be replaced when you notice damage during strainer cleaning.

Cleaning/Replacement:

NOTE: Cleaning the ‘Y’ strainer requires opening the ‘Y’ strainer housing. This procedure should be done atthe end of the work shift when the reservoir’s water level will be at its lowest.

1. Turn off SHUT-OFF ball valve.2. Unscrew the bottom of the ‘Y’ strainer.3. Remove the screen from inside the ‘Y’ strainer housing and examine.4. Choose one:• Remove any debris inside the ‘Y’ strainer and rinse the cylindrical screen.• If the strainer is damaged, replace it.5. Slip the screen back into position6. Reassemble the ‘Y’ strainer housing.

15.4 Water Pump MaintenanceThe water pump is a 5-stage diaphragm with a 3.4 (GPM) output at 50 PSI. Because the pump is mountedbelow the reservoir, it does not need priming.

The only maintenance required is a monthly check of the water pump pressure to ensure proper dustsuppression and water pump life.

Turn OFF the auxiliary engine before you work on the water pump.

15.5 Water Pump Pressure CheckPressure Verification:

1. Use a gauge to check the pump’s output pressure. Attach a pressure gauge (able to measure at least 500PSI) to the boiler drain on the front of the fill hose storage rack.

2. Open the boiler drain.3. Turn the console control panel switch, which operates the water pump, to the ON position.4. Be sure all the console control panel switches operating the sweeper’s water functions are in the OFF

position.5. Read the gauge and choose one:• If the gauge reads roughly 50 PSI, no adjustment is needed.• If the pressure gauge reading is considerably different from 50 PSI, you may need to adjust the water

pump’s relief valve. Pressure that is jet too high can cause premature water pump failure.6. Locate the relief valve in the group of fittings attached to the pressure port of the pump.7. Screw the jam nut away from the relief valve’s body.8. Turn the hexed stem of the relief valve to adjust the water system pressure.9. When the water pressure is roughly 50 PSI, run the jam nut back against the body of the relief valve.

15.6 Water Nozzle Cleaning/ReplacementA dust suppression system nozzle needs cleaning when it is clogged and water flow is restricted.

Due to dusty conditions encountered during sweeping operations, dirt and debris particles entering the dustsuppression system are sometimes small enough to pass through the ‘Y’ strainer. These particles can build upwithin a nozzle’s openings, restricting water flow. When this occurs, the nozzle must be cleaned or replaced.

Cleaning/Replacement:

1. Unscrew the nozzle retainer cap and set it aside.2. Remove the spray tip and strainer.3. Wash the strainer and examine it.4. Choose one:• If washing the strainer has removed all particles

or debris, set aside the (now clean) strainer.• If the strainer can no longer be thoroughly

cleaned, it needs to be replaced.5. Wash the spray tip and examine it.6. Choose one:• If the spray-tip opening is clogged, insert a

small-gauge wire into the spray-tip opening to clear any debris lodged inside.

• If the spray tip is damaged, it needs to be replaced.

7. Reassemble the nozzle, replacing any damagedparts as necessary.

8. Unscrew the bottom of the ‘Y’ strainer housing todrain the water reservoir(s).

9. After the water flow stops, reassemble the ‘Y’strainer housing.
