ELECTRICAL SAFETY WARNINGS

DO ensure that the machine is properly grounded through the power supply in accordance with the National Electric Code and local codes. If in doubt, have the receptacle checked by a qualified electrician. DO plug the machine into a GFCI (Ground Fault Current Interrupter) protected outlet, if possible, for maximum safety. DO wear rubber footgear when operating machine. DO immediately replace or repair worn or damaged power cords. DO NOT spray water on the motor, motor starter or any electrical parts. DO NOT operate the machine outside without protection in rain, snow or wet precipitation. DO NOT attempt to service the machine without first disconnecting and locking out the power supply. Only a qualified electrician or technician must do service. DO NOT alter, modify or use the machine with any voltage, phase or hertz other than specified on the machine data plate.

DO NOT stand in water while operating this machine. DO NOT allow machine to operate unattended.

OPERATIONAL SAFETY WARNINGS DO ensure that the trigger gun is properly secured when the unit is in operation to prevent hose whip. DO frequently inspect all connections, fittings and hoses for high-pressure water leaks. Any leaks must be immediately repaired to prevent potential injury. DO immediately replace and pressure hose that shows signs of leaks, damage, excessive wear or if the outer casing is worn through. DO wear eye protection and gloves when using this machine. DO open the trigger gun momentarily after pump is shut down to release trapped pressure. DO NOT attempt to use the machine for anything other than its intended purpose of water pressure cleaning using a hand held gun. DO NOT run any fluid other than water with or without detergent through the machine. DO NOT allow the water stream from the nozzle to contact the skin or any other part of the body. Serious injury or death can result. WARNING: IF A WATER JET OF ANY KIND PENETRATES THE SKIN, SEEK MEDICAL ATTENTION IMMEDIATELY. SERIOUS INJURY OR DEATH CAN RESULT FROM INJECTION OF CHEMICALS THROUGH THE SKIN BY A WATER JET. DO NOT stand directly over the high-pressure hose during operation or while hose is still pressurized. DO NOT attempt to operate the machine at higher than its rated pressure. DO NOT operate the machine if any components are worn or damaged. DO NOT change or modify any components, devices or systems on the machine from the original factory built configuration. When replacing parts, use only factory replacement parts or part certified by a competent authority to be identical in rating, function and fit. DO NOT touch the exhaust stack or place any part of you body over the top of the stack. Serious burns may result.

DO NOT put gasoline or anything other than kerosene, fuel oil or diesel fuel in the fuel tank. DO NOT operate the machine in an explosive atmosphere. DO NOT remove, bypass, alter or otherwise negate the function of protective safety devices. WARNING: NEGATING SAFETY DEVICES, CHANGING THE ORIGINAL FACTORY DESIGN CONFIGURATION OR REPLACING PARTS WITH NON-IDENTICAL PARTS CAN RESULT IN SERIOUS INJURY OR DEATH.

ASSEMBLY AND PREPARATION FOR OPERATION

1. Remove any remaining packing materials, manuals, etc. 2. Connect hose and wand to outlet connection on the machine. 3. Put fuel into the fuel tank. WARNING: DO NOT PUT GASOLINE INTO FUEL

TANK! The preferred fuel is No. 1 or No. 2 fuel oil or diesel fuel and the machine is factory adjusted for diesel. The machine can also use kerosene; however, if kerosene is used, burner air band readjustments will be necessary. Contact Daimer for instructions.

4. All 230-volt and 440-volt models are shipped from the factory without power plugs on the cords due to the many different receptacle types and configurations. It will be necessary to install a power plug on the cord to match the type of receptacle in your facility.

INSTALLATION CONSIDERATIONS

This machine is mounted on 10” rubber tired wheels and can be moved easily about from place to place as needed. The area of machine use should be free of combustible materials and explosive atmosphere (solvent vapors, etc.) with sufficient ventilation to supply combustion air and to remove exhaust gases. CAUTION: COMBUSTION WITH INADEQUATE OXYGEN PRODUCES DANGEROUS CARBON MONOXIDE.

Ensure that there is at least a four-foot clearance directly above the stack to the ceiling or other part of the building structure. Avoid placing the machine directly under sprinkler heads or near combustible materials. Ensure that adequate means for water disposal exists in the cleaning area.

OPERATION

TO OPERATE

1. Plug in electrical extension cord to suitable power supply. 2. Connect 5/8” heavy-duty water hose to a hose bib (spigot) and connect the male

end to the water inlet swivel fitting on the machine. 3. Open valve on water supply to the machine (spigot) and wait until water is free

flowing with a steady stream exiting the nozzle. 4. If detergent chemicals are to be used in the cleaning process, put the end of the

chemical siphon pickup tube into a container of chemical. Ensure that the chemical valve on the machine control panel is fully closed. WARNING: THE PANEL SOAP VALVE MUST BE CLOSED AT ALL TIMES UNLESS THE END OF THE SIPHON PICKUP TUBE IS SUBMERGED IN LIQUID DETERGENT OR WATER. FAILURE TO DO SO WILL RESULT IN SEVERE PUMP DAMAGE.

5. Turn the rotary switch to the PUMP position. Before proceeding further, ensure that a steady stream of water is flowing from the nozzle with no pressure surges. Pressure surges are caused by air in the water hose, machine heating coils and sometimes the building water piping. 30 to 60 seconds is usually required to clear all air from the system on initial start up. The machine is now ready for operation in the cold-water high-pressure cleaning mode if desired.

6. Turn the rotary switch to the BURNER position. Wait 60 seconds for temperature and pressure build up and proceed with cleaning in the hot high-pressure mode.

7. If the machine is equipped with optional steam cleaning capability, the machine may be switched to steam as follows:

a. Turn rotary switch to the OFF position. b. Remove the pressure wash nozzle from end of wand and install steam

nozzle. c. Turn rotary switch to the BURNER position.

8. If cleaning solution is to be used, open the SOAP valve on the machine control panel to draw chemical into the system. Adjust the chemical flow rate to obtain the most effective cleaning action. When shutting down after use, flush the chemical injection system with clear water by placing the siphon pick up tube into a container of water, partially open the SOAP valve and run the machine in cold water mode for approximately 30 seconds with water exiting the nozzle. Failure to flush the chemical injector after each use will result in injector clogging.

9. After the machine is turned on in either hot high-pressure mode or steam mode, wait 60 seconds for temperature and pressure build up and then proceed with cleaning.

10. When the rotary switch is turned to the BURNER position, the burner will not start until the trigger gun is opened and high-pressure water flow begins.

11. The burner will cycle on and off automatically each time that the trigger gun is operated. Do not rapidly trigger the gun on and off as this will cause excessive wear and tear to the machine control components.

12. Do not run the machine for more than 2 or 3 minutes in bypass mode (pump running, gun off) to prevent pump damage due to heat build up. For longer intervals, shut off the pump.

CLEANING PROCEDURE

1. Direct steam and /or hot water onto surface to be cleaned at 30º to 45º angle with the surface. Vary the distance from the nozzle to the surface according to the severity of the cleaning required. Twelve (12) inches is about average.

2. Open SOAP valve by turning knob approximately ½ turn counterclockwise. Observe the cleaning action at the nozzle and increase or decrease the cleaning solution flow with the valve to get optimum cleaning effect.

3. When cleaning has been completed, completely close the SOAP valve on the unit and rinse all detergent residues from the surface.

4. Use only a concentrated liquid chemical in the solution system (no powders). Do not use corrosive (acids or PH greater than 12.5 in the concentrated form). Do not mix two or more chemicals together.

SHUT DOWN

1. Turn the rotary switch to the PUMP position. 2. Flush chemical systems by placing the end of the chemical pickup tube in clear water for

thirty seconds with chemical valve partially open. 3. Run the machine in the cold-water mode for at least one minute to get all of the heat out

of the coil. 4. Turn the rotary switch to the OFF position. 5. Turn off water supply to the machine. 6. Disconnect power supply to the machine. 7. If the machine will be subjected to freezing conditions, steps must be taken for freeze

protection. See next section.

FREEZE PROTECTION Mix one gallon of suitable alcohol anti-freeze with water in the proper ratio to protect against the lowest anticipated temperature. Determine the mixing ratio from the anti-freeze container instructions. IMPORTANT: DO NOT USE ETHYLENE GLYCOL AUTOMOTIVE ANTI-FREEZE. USE AUTOMOTIVE WINDSHIELD WASHER FLUID.

For all SUPER MAX™ 12800 Series models use the following procedure:

Pour the anti-freeze solution into a suitable container, such as a 5-gallon bucket. Connect a 2-foot to 3-foot length of hose to unit and insert other end into the anti-freeze. Connect electrical power and turn on pump switch and allow unit to fill with anti-freeze. If there is water in unit, allow pump to run until anti-freeze may be seen exiting the nozzle. Allow the anti-freeze to flow into a 5-gallon bucket to save anti-freeze. Turn off pump.

Machine is now ready for storage. When system is to be operated again, connect garden hose to water supply and turn water on. Let anti-freeze drain back into 5-gallon bucket. This procedure must be done after each usage of the steam cleaner until freezing conditions no longer exist. Damage to heat exchanger coils will result if machine is stored at 32º or lower temperature without anti-freeze protection. The coils are not self-draining! If difficulty is encountered in getting pump to pick up suction of the anti-freeze from the bucket, do one of two things:

1. Reconnect a water hose to the machine water inlet, turn on the water supply and run pump for a few seconds. This will prime the pump. Disconnect the water hose,

connect anti-freeze hose to fill hose and pump housing. When full, drop the hose into the anti-freeze bucket and proceed as above.

2. With anti-freeze hose connected, lift end of hose to level above the pump and pour water or anti-freeze in the hose and pump housing. When full, drop the hose into the anti-freeze bucket and proceed as above.

MAINTENANCE

BURNER AND AIR BAND ADJUSTMENT The high efficiency flame retention oil burner used on the SUPER MAX™ 12800 series are capable of using a wide range of oils including kerosene, No. 1 oil, No. 2 oil or diesel fuel. The preferred fuel is diesel and the machines are factory adjusted for diesel. If kerosene is to be used in the machine it will be necessary to readjust the fuel/air ratio at the burner by slightly opening the air bands. Contact Daimer for instructions. GENERAL BURNER MAINTENANCE The burner electrodes should not be tampered with unless burner malfunction occurs. If necessary to adjust or replace electrodes, follow the steps in the burner maintenance instruction written by burner manufacturer. The in line fuel filter must be replaced periodically to prevent burner operational problems. The frequency will vary greatly depending on fuel contamination, but once every 3 months is a reasonable average. Being careful to use clean fuel and minimizing contamination during the fuel tank filling process can minimize fuel filter contamination. PUMP MAINTENANCE All SUPER MAX™ 12800 Series machines are equipped with top quality oil bath ceramic plunger triplex pumps with rebuildable wet ends. The biggest enemy of this type of pump is cavitation cause by inadequate water supply. An inadequate water supply can result from dirty filters or filter screens on the suction side, inadequately sized or extra long (over 25-foot) supply hoses, negative suction pressure and other causes. It is recommended that if you have an unusual or difficult water supply situation, that you call Daimer Industries, Inc. at (800) 471-7157 for advice. It is recommended that the pump oil be changed after the first 50 hours of operation and thereafter at intervals of 500 hours. Use the following types of oil:

All SUPER MAX™ 12800 models SAE-30 Non-Detergent Motor Oil

Valves and seals on high-pressure pumps are wear parts similar to tires on an automobile. As they wear over time there will be a gradual degradation of output pressure. The pumps can be rebuilt to original operating specifications with the addition of seal kits and valve kits. Contact Daimer for assistance. High-pressure pumps are limited to a maximum of 160ºF incoming water temperature (water is heated after the pump in the pressure washer). Inlet water temperatures above 160ºF can cause severe pump damage and will invalidate the warranty. It is best to use only cold incoming water to the pressure washer, but if hot water must be used, the burner firing rate must be lowered by using a small burner fuel tip or the machine must

be equipped with thermostat control to cycle the burner off and on to maintain proper temperature control. BELT MAINTENANCE On models equipped with belt drive it is essential that belt tension be checked frequently and adjusted as needed. Pressure washers that are regularly used on a daily basis should have belt tension checked quarterly. To check belt tension, disconnect power to the machine and remove belt guard. Depress each belt halfway between the pulleys using your fingers. If the deflection is more than 1/2" at the midpoint, the belt must be re-tensioned. All belts in a set must be tensioned the same. When belts are replaced is is best to replace them as a set. Replace belt guard after checking or adjusting belt tension. CAUTION: NEVER OPERATE THE MACHINE WITHOUT BELT GUARD INSTALLED. UNLOADER VALVE ADJUSTMENT All SUPER MAX™ 12800 Series models are equipped with a sophisticated regulator/unloader valve. This valve regulates pressure in the system and bypasses water when the trigger gun is closed. Unloaders on various models may differ slightly in appearance, but they all have a spring (some are hidden inside the valve housing) that is compressed by a nut on a threaded rod. The system pressure can be increased by tightening the spring and decreased by loosening the spring. Some models are equipped with a knob that can be used to increase or decrease spring tension. Always adjust the unloader with trigger gun off. Adjust in small steps checking each time by triggering the gun and observing pressure on a test gage. Never adjust the pressure to setting higher than the machine rating. Never forcibly tighten a spring beyond the stop on the adjustment mechanism. When an unloader is over-tightened, the device will not properly function to relieve pressure when the gun is shut off. This can result in dangerously high pressures within the systems that can damage the equipment severely and cause injury. NOTE: A gradual reduction in system pressure as the pressure washer is being used over time is an indication of nozzle wear, rather than need for unloader adjustment. You will not be able to restore pressure loss caused by nozzle wear by adjusting the unloader. A sudden loss of pressure is an indication of a dirt clogged nozzle rather than the need for unloader adjustment. Unloader adjustment is a delicate procedure and should be done only when absolutely necessary. For operational purposes, system pressure can best be changed, if needed, by changing size of the nozzle tip. For more information or assistance, contact Daimer. HOSE MAINTENANCE High-pressure hoses on a pressure washer are subject to wear and tear during normal use and, like tires on an automobile, must be frequently monitored for wear and/or damage. When problems are found they must be promptly corrected. It is recommended that high-pressure hoses be inspected at least monthly if the pressure washer is frequently used. Problems to look for are; severe wear or abrasions on the outer cover, cuts or splits, or leaks near the hose ends. If hose ends are replaced, they must be replaced with the proper size and type of fitting and must be crimped on a clean-cut hose end (prepared with an abrasive cut off saw) with hydraulic crimper. This should be done by a hydraulic hose specialist or by Daimer.
