Do not allow anyone to operate the Hole Digger without first reading this Operator Manual and becomingfamiliar with its operation. The manufacturer of this Hole Digger has gone to great extremes to provide theowner(s) and/or operator(s) with the finest equipment available for its intended job function of digging holesin ice and earth formations. Yet, the possibility exists that the Hole Digger can be utilized in and/or subjectedto job applications not perceived and/or anticipated by the manufacturer. Such misuse and/or misapplicationof the Hole Digger can lead to the possibility of serious damage, injury or even death. It is the responsibilityof the owner(s) and/or operator(s) to determine that the Hole Digger is being utilized and/or operated withinthe scope of its intended job function. It is the responsibility of the owner(s) and/or operator(s) to establish,monitor and constantly upgrade all safety programs and/or practices utilized in and for the operation of theHole Digger. The purpose of such programs is to provide for owner(s') and/or operator(s') safety. Operators

must be instructed to recognize and avoid unsafe conditions associated with their work (29 CFR 1926.21(b)(2)) and/or applicable updated revisions. It is the responsibility of the owner(s) and/or operator(s) todetermine that no modifications and/or alterations have been made to the Hole Digger. Modifications and/oralterations can lead to the possibility of serious damage, injury or even death. It is the responsibility of theowner(s) and/or operator(s) to make this Operator Manual available for consultation during all phases ofoperation. Refer to OSHA 2207 which contains all OSHA job safety and health rules and regulations (1926and 1910) covering construction.

The concept of portable, one and two man operated, hole digging equipment has been successfullyutilized for over forty years as a practical solution to many types of hole digging job requirements.The basic concept is proven and well accepted within the associated marketplaces as an alternativemethod to manual labor and/or larger, mounted earth drilling machinery. Use of a Hole Diggerrequires strenuous work activity. This type of work activity can be considered to be greater inmagnitude than that experienced with the use of many other types of both light construction andlawn and garden related equipment. This type of work activity should only be attempted by operatorsof adequate physical size and stature, mental awareness and physical strength and condition. Eachoperator is required to supply a resultant force that counteracts/balances and/or resists the naturaltorque and kickback forces generated during the hole digging process. The body parts mostnoticeably affected during the digging process are the arms, hands, wrists, shoulders, lower backand legs. The hole digging process can also produce excessive stress/strain directly to the backmuscles, spinal vertebrae and many other body parts. Back related pain can be a side effect of thehole digging process. An operator with a chronic back related problem or a history of back and/orother medically related problems should not attempt to utilize the Hole Digger. Use of the HoleDigger may only aggravate this and any other medically related problem. The torque and kickbackforces generated and/or encountered correspond to the natural laws of physics and are inherent tothe hole digging process. They can not be changed or totally eliminated with portable one and twoman operated, hole digging equipment of this design. Proper operating positions and techniques, asoutlined in this manual, can be successfully utilized to minimize the effects of the torque andkickback forces upon the human body. Because of the diverse type of prevailing digging conditions,operator experience levels and operator physical characteristics, no warranty, guarantee,representation and/or liability is made by the factory as to the absolute correctness or sufficiency ofany operational procedure, operational position and/or technique. There is no absolute guaranteethat an operator of any given experience level, physical size and/or physical condition will beimmune to the possibility of and/or probable physical side effects of the normal hole diggingprocess. The normal hole digging process includes the auger striking buried obstructions (roots,rocks, etc.) and the resulting torque and kickback forces created. Each potential operator of the HoleDigger must be made aware of and assume the operational and physical liability described and/orassociated with the hole digging process when utilizing the Hole Digger. Each potential operator notwilling to assume the operational and physical liability described and/or associated with the holedigging process should not operate the Hole Digger. Proper levels of operator experience, skill andcommon sense are essential for maximizing the safe and efficient operation of the Hole Digger.

This can lead tothe possibility of property damage and/or personalinjury. Keep all body parts, loose clothing, foreignobjects and onlookers clear of the rotating augerand/or auger extensions.

5) Operators must be in proper physical condition,mental health and not under the influence of anysubstance (drugs, alcohol, etc.) which might impairvision, dexterity or judgment. Working with the HoleDigger is strenuous. If you have any condition thatmight be aggravated by strenuous work, check withyour doctor BEFORE operating the Hole Digger. Guard

240H ONE MAN HOLE DIGGERFORM GOM14081201, VERSION 1.0 7

against the possibility of back related injuries. Alwayslift the Hole Digger with leg muscles and not with theback. Operators must be of adequate height so that forany given operating configuration, the operatorhandle(s) remain below their shoulder sockets. Do notoperate the Hole Digger if this condition is not satisfied.The 200 Series Hole Diggers require that the operatorbe of proper height, weight and strength to maximizedigging efficiency and minimize the possibility ofpersonal injury.

6) Prolonged use of the Hole Digger (or other, similarmachines) exposes the operator to vibrations whichmay produce Whitefinger Disease (Raynaud'sPhenomenon). This phenomenon reduces the hand'sability to feel and regulate temperature, producesnumbness and burning sensations and may causenerve and circulation damage and tissue necrosis.Antivibration systems do not guarantee that you will notsustain Whitefinger Disease. Therefore, continuous andregular users should closely monitor the condition oftheir hands and fingers. After each period of use,exercise to restore normal blood circulation. If any ofthe symptoms appear, seek medical adviceimmediately.

7) Clothing must be sturdy and snug fitting, but allowcomplete freedom of movement. Never wear loosefitting jackets, scarves, neckties, jewelry, flared orcuffed pants or anything that could become caught oncontrols or moving parts. Wear long pants to protectyour legs. Protect your hands with heavy duty, nonslipgloves to improve your grip. Good footing is mostimportant when operating the Hole Digger. Wear sturdyboots with nonslip soles. Steel-toed safety shoes arehighly recommended. Keep shoes properly laced.Never wear tennis shoes or other, similar type shoeswhich afford little or no protection. Wear an approvedsafety hard hat to protect the operator’s head wherethere is a danger of head injuries.

8) Noise, generated by the engine of the Hole Diggerand the actual process itself, can damage your hearing.The 200 Series Hole Digger operates with a noiseemission greater than 70dBA. Hearing protection isrequired while operating or when near operatingequipment. Continuous and regular operators shouldhave their hearing checked regularly.

9) Flying debris, generated by the hole diggingprocess, can cause eye injury. Eye protection isrequired while operating or when near operatingequipment.

10) Visually inspect the Hole Digger, auger(s), augerextension, and accessories for damaged or worn parts.Inspect each auger for the proper screw bit and blade.Look for loose and/or damaged handle grip areas.Check for loose and/or broken parts. Determine thatoperator controls work freely, all safety devices areoperative and information/safety decals are readable.Check to determine that the Hole Digger and all relatedaccessories are in good mechanical conditionBEFORE utilization.

11) Contact appropriate representatives to determineif/where electrical cables, gas lines and otherhazardous items are buried under the work surfaceBEFORE utilization. The Hole Digger and relatedaccessories are not classified as being insulated.Contact with buried electrical cables, gas lines andother hazardous items can result in electrocutionand/or an explosion.

12) Know how the controls operate. Know how to stopthe engine quickly in an emergency. Always start theengine according to the instructions as outlined in thismanual to minimize the possibility of unexpected oruncontrolled auger rotation. Unexpected auger rotationcan cause loss of machine control, and the possibilityof property damage and/or personal injury.

13) Never exceed the recommended capacities of theHole Digger. Refer to the Specifications section of thismanual for more detailed information. Always utilize thecorrect auger and auger extension series designed foruse with the Hole Digger. Some Hole Diggers canutilize specially designed augers intended for drillingholes through ice. Such an auger will find limitedsuccess when utilized to dig earth. Earth augers arenot designed to drill through ice. Use of an incorrectauger or auger series can result in property damageand/or personal injury.

14) Do not operate the Hole Digger on a jobsitelocation where kickback forces generated during thehole digging process can allow body parts to come indirect contact with a vertical wall, foundation or othersupport type structures in close proximity. Such anoccurrence can result in property damage and/orpersonal injury. Always maintain a safe and reasonabledistance from these types of structures.

15) Breathing Carbon Monoxide fumes while operatingthe Hole Digger can result in property damage and/orpersonal injury. The normal operation of the HoleDigger is outdoors where the potential effects ofCarbon Monoxide to the operator are minimized. If theHole Digger is operated in a closed area (indoors oroutdoors), determine if supplemental ventilation is


required to minimize the potential effects of CarbonMonoxide to the operator. Follow all current OSHAregulations pertaining to ventilation.

OPERATION.

1) Give complete and undivided attention to the job athand. Do not chew gum, smoke and/or use smokelesstobacco while utilizing the Hole Digger. Do not attemptto eat and/or drink while utilizing the Hole Digger.Determine that eyeglasses and/or hearing aid devicesand other medical related devices are properlysecured. Keep shoes properly laced. Use of the HoleDigger is strenuous and causes fatigue. Help preventthe cause of an accident. Plan to take work breaks asrequired to help maintain proper mental and physicalalertness.

2) The 200 Series Hole Diggers are not sealed orinsulated. Do not operate any Hole Digger in anexplosive atmosphere or near combustible materials.Refer to current OSHA rules and regulations.

3) Gasoline is an extremely flammable fuel. Useextreme caution when handling gasoline or mixing fuel.Always utilize UL®, CSA or CE approved containers forthe storage and/or transportation of fuel. Do not smokeor bring any fire or flame near the fuel. Always shut offthe engine and allow it to cool before refueling. Neverremove the fuel tank filler cap while the engine isrunning. Never operate an engine without a fuel tankfiller cap. Select bare ground for fueling and move atleast 10 feet from the fueling spot before starting theengine. Wipe off any spilled fuel before starting theengine and check for leakage. If a fuel or oil leak isfound, do not start or run the engine until the leak isfixed and the spillage has been wiped away. Take carenot to get fuel or oil on your clothing. If this happens,change your clothing immediately. Some 200 SeriesHole Diggers utilize a 2 Stroke gasoline engine. TwoStroke engines require the addition of oil mixed with thegasoline for lubrication. The 240 Series Hole Diggerutilizes a Four Stroke engine and does not require oil tobe mixed with gasoline. Before operating the HoleDigger, refer to the Specifications section of thismanual for more detailed information regardinggasoline and lubrication requirements.

4) The 200 Series Hole Diggers are designed for useby one operator. Use of a one man Hole Digger bymore than one operator can lead to confusion and loss

of control, resulting in damage and/or personal injury.Never operate the Hole Digger with an impropernumber of operators. Such a configuration can result inproperty damage and/or personal injury. If it is felt thata greater number of operators is required to furnishadditional "down pressure" to the auger, STOP andcontact the Customer Service Department for specificoperational and service/maintenance information.There is no charge for this service.

5) Do not operate the Hole Digger with onlookers closeby. Caution all onlookers to stand clear. The holedigging process can result in flying particles beingemitted at high velocity and striking the operator and/oronlookers, This can lead to the possibility of propertydamage and/or personal injury. Wear proper safetyeyewear. Keep all body parts, loose clothing andforeign objects clear of the rotating auger.

6) Do not utilize a shovel and/or foreign object toremove the loose soil from a hole area while the HoleDigger is in use. Such a practice can result in theshovel and/or foreign object to become entrapped bythe rotating auger, leading to the possibility of propertydamage and/or personal injury.

7) Start the engine according to the instructions asoutlined in this manual to minimize the possibility ofunexpected auger rotation. Unexpected auger rotationcan result in the loss of machine control and thepossibility of property damage and/or personal injury.The 240 Hole Digger is designed for the engine to bestarted by the operator’s left hand only. The operator’sright hand controls the twist grip throttle and enginespeed. Reversing the process by starting the enginewith the right hand will position the hot engine mufflerin close proximity to the operator’s body. This is not anapproved configuration because it can result in injuryfrom the hot muffler and/or breathing Carbon Monoxidefumes during operation. If you have any questionsregarding proper starting procedures, contact theCustomer Service Department BEFORE utilization.There is no charge for this service.

8) Start and operate the Hole Digger only in a wellventilated area. Carbon Monoxide fumes given off byan engine are poisonous. Breathing these fumes canresult in property damage and/or personal injury.Operate the Hole Digger only when/where visibility andlight are adequate for the job at hand. Work carefully.Always hold the Hole Digger firmly with both hands.


Wrap your fingers around the handle grips/grippingareas, keeping the grips/gripping areas cradledbetween your thumbs and forefingers. Alwaysdetermine the operator handle and grips/gripping areasare in good condition and free of moisture, pitch, oil orgrease. Wear gloves to improve your grip. Never leavethe Hole Digger running unattended.

9) Stop the engine between each hole. Allowing theengine to remain operating between each holesubstantially increases the potential for propertydamage and/or personal injury. Special care must beexercised in slippery conditions and on difficult, unevensurfaces. Watch for cracks, high spots and othersurface irregularities. Keep proper footing and balanceat all times. The normal use of the Hole Digger is onlevel ground. Other digging terrains can be dangerousand should be avoided. Only properly trained operatorsshould attempt these techniques.

10) Contact with a hot engine muffler can causeproperty damage and/or personal injury. Remain clearof a hot, engine muffler at all times. Do not overspeedthe engine by altering the governor setting or bydisconnecting the engine governor (if so equipped).Serious damage to the engine and/or personal injurycan result.

11) The 200 Series Hole Diggers are powered bygasoline engines which produce Carbon Monoxidefumes during the combustion process. CarbonMonoxide fumes are poisonous. Breathing CarbonMonoxide fumes while operating the Hole Digger canresult in property damage and/or personal injury. Thenormal operation of the Hole Digger is outdoors wherethe potential effects of Carbon Monoxide to theoperator are minimized. If the Hole Digger is operatedin a closed area (indoors or outdoors), determine ifsupplemental ventilation is required to minimize thepotential effects of Carbon Monoxide to the operator.Follow all current OSHA regulations pertaining toventilation.

12) Because this Hole Digger is classified as a lowcost, hand held, low horsepower, portable typemachine, it is limited in the number of practical and/orsuitable job applications for this type of equipment. Aparticular job site, actual soil conditions, jobspecifications and operator experience/skill/commonsense may dictate that a different type of machine (with

characteristics of higher purchase cost, being mountedto a carrier vehicle, with greater horsepower and lessmobility), method and/or process be utilized to properlycomplete the job with the degree of efficiency andsafety required. Contact the Customer ServiceDepartment for specific information regarding suitablejob applications, job sites, soil conditions and operatorexperience/skill/common sense recommendations forthis Hole Digger BEFORE utilization. There is nocharge for this service.

MAINTENANCE REPAIR AND STORAGE.

1) Use only genuine, approved replacement parts formaintenance and repair. Use of parts manufactured byothers can result in property damage and/or personalinjury.

2) Follow the Service instructions as outlined in theappropriate section of the Operator Manual.

3) Always stop the engine and disconnect the sparkplug wire BEFORE checking or working on the HoleDigger.

4) Always properly maintain the Hole Digger.Frequently check all fasteners and individual parts.Built in safety features are effective only if they aremaintained in good working condition. Replace anyquestionable part or assembly with a genuine,approved replacement part. Do not forsake propermaintenance for the price of a few replacement parts.Proper maintenance does not cost---it actually paysdividends. Do not attempt any maintenance or repairwork not described in the Operator Manual. Have suchwork performed at your dealer's servicing shop.

5) Determine the engine throttle control and throttlecable assemblies are not damaged and allow forcomplete freedom of movement. This is necessary toallow them to perform their intended job functions. Donot operate the Hole Digger with a damaged or wornthrottle control and/or throttle cable assembly.

6) A worn or damaged engine muffler is a fire hazardand may cause loss of hearing. Check to see that themuffler is in good condition. If the muffler is equippedwith a spark arresting device, determine that it is inproper working condition at regular service intervals.Replace the spark arresting device with an approved


replacement if there is any question of its integrity. It isthe responsibility of the owner(s) and/or operator(s) toprovide for and properly maintain a USDA approved,spark arresting muffler in an area where specified bylaw. Check with appropriate governing agencies formore specific information. The Hole Digger must notbe operated if the muffler is faulty or has beenremoved. Contact with a hot muffler can cause propertydamage and/or personal injury. Remain clear of a hotengine muffler.

7) Maintain all safety and operation decals in propercondition. If any decal becomes damaged and/orunreadable, replace with a genuine, factory approved,replacement part only.

8) The Hole Digger may utilize locking type hexagonnuts to minimize the effects of vibration. Replace all selflocking hardware with genuine, factory approved,replacement parts only.

9) Consult the material supplied by the enginemanufacturer for specific information relative to properoperational, lubrication and storage requirements.

10) Replace the auger teeth/blade and screw bit whensigns of excessive wear are seen. When such parts arenot replaced at proper intervals, undo wear will occur atthe boring head and auger flighting. The end result isan inverted cone configuration for the auger, whichusually requires complete replacement. FIGURE 1.Digging with equipment that is past its useful servicelife or that have not been properly maintained canresult in substandard productivity, excessive propertydamage and/or personal injury. Auger service life canbe greatly extended with constant auger wear partmaintenance.

FIGURE 1

11) At the conclusion of the useful service life of theHole Digger, drain and properly dispose of all fluids perlocal requirements. Disassemble engine andtransmission components. Wear appropriate safetyapparel during the disassembly process. Recyclealuminum, steel and nonmetallic components properlyper local requirements.

Before Starting the Engine

FILLING THE ENGINE CRANKCASE WITH OIL.

Tools Required:

1 each, small, clean funnel with a flexible extensionspout.

Filling the engine crankcase with oil will require a levelworking platform of sufficient size and appropriateheight. As an alternative, the transmission driveshaftcan be securely mounted in a suitable bench vice.

1) Wipe any dust or dirt from the crankcasedipstick/filler plug area. Remove the dipstick/filler plug.

2) Using the funnel, add oil to the engine crankcase.For proper classifications and/or amount, consult thematerial supplied by the engine manufacturer forspecific information.

3) Replace the dipstick/filler plug and tighten. Wipe offany excess spilled oil. Properly dispose of the spilledoil.

4) Consult the material supplied by the enginemanufacturer for other service related informationincluding oil change interval.

Do not operate the Hole Digger unless proper oillevel is maintained. Improper oil level can result inproperty damage and/or personal injury. Consultthe material supplied by the engine manufacturerfor information relative to proper maintenanceprocedures.


FILLING THE HOLE DIGGER TRANSMISSION WITHGREASE.

Application: All 200 Series models.

The transmission is filled at the factory with 8 fluidounces (224g) of high temperature transmissiongrease and should not require additional service whenplacing the Hole Digger into initial service. The factoryutilizes the Fisk Brothers (Lubriplate Brand) GR132grease which features an EP additive. The EP (extremepressure) additive allows the grease to properly cling tothe gear teeth and provide lubrication at high rotationalspeeds. Without the addition of and EP additive,normal grease will not cling to the teeth, resulting inabnormal wear and reduced service life. With normalusage, the transmission grease should not requirefurther replacement until the centrifugal clutchassembly is replaced. For further information, refer tothe Repair section of this manual for additionalinformation.

Do not fill the Hole Digger transmission with oil.The transmission does not incorporate seals toprevent the oil from draining from the bearings andshafts. Such an occurrence will allow the oil todrain with the potential for property damage.

FILLING THE ENGINE FUEL TANK.


Tools Required:

1 each, small, clean funnel.

The 240 Hole Digger utilizes an all-position, FourStroke, gasoline engine. While this engine mayhave the same physical appearance of aconventional Two Stroke engine, the lubricationsystems are completely different. The Honda GX35engine does not require oil to be mixed withgasoline. The crankcase oil does not function as areservoir for an oil injection system.

1) Carefully clean the filler cap and surrounding area toinsure that no dirt or debris falls into the fuel tank.

2) Fill the fuel tank with fresh, clean, unleadedautomotive gasoline. Leaded "regular" grade gasolineis an acceptable substitute. DO NOT USE GASOLINECONTAINING METHANOL (WOOD ALCOHOL).Gasoline containing a maximum of 10 per cent ethanolor grain alcohol (sometimes referred to as Gasohol)may be used but requires special care when the engineis stored for extended periods.

3) Use of a properly blended gasoline for operationduring the intended season will result in easier enginestarting. Do not use gasoline left over from the previousseason of operation.

4) Never fill the fuel tank completely full. Instead, fill thefuel tank to within 1/4 to 1/2 inch of the top of the tankto provide space for fuel expansion. Always wipe anyfuel spillage from the engine and the Hole Diggerbefore starting the engine.

DO NOT SMOKE NEAR THE FUEL TANK. DO NOTFILL THE FUEL TANK WITH THE ENGINE RUNNINGOR IF IT IS HOT. ALLOW AMPLE TIME BETWEENEACH REFUELING FOR THE ENGINE TO COOL. ANIGNITION SOURCE IN CLOSE PROXIMITY TO THEFUEL TANK CAN BE THE SOURCE OF ANEXPLOSION, RESULTING IN PROPERTY DAMAGEAND/OR PERSONAL INJURY. CONSULT THEM AT E R I A L S U P P L I E D B Y T H E E N G I N EMANUFACTURER FOR INFORMATION RELATIVETO PROPER FUELING PROCEDURES.

SET UP FOR DIGGING.


1) The Hole Digger is designed for one operator totransport it by the operator handle to, while on, andfrom the job site. Connect the auger to the Hole Diggerwith the correct, factory-supplied auger pin. All 200Series Hole Diggers utilize the 3/8 inch (9.5 mm)diameter pin, PN 2121 Auger Pin to connect to roundsection of shaft. FIGURE 2.


FIGURE 2

The auger pin supplied with the Hole Digger isdesigned to withstand the high stress encounteredwhile digging. Use of any other connecting device,including cap screws, bolts, pins, etc., can result indamage to the Hole Digger driveshaft and/or augerdrive hub. Improper connecting devices can causeproperty damage and/or personal injury.

DO NOT CONNECT THE AUGER TO THE HOLEDIGGER WITH THE ENGINE RUNNING. A SUDDENCHANGE IN THE ENGINE SPEED WILL RESULT INHOLE DIGGER DAMAGE AND/OR PERSONALINJURY.

THE 240 HOLE DIGGER IS DESIGNED FOR ONEMAN OPERATION. USE BY MORE THAN ONEOPERATOR WILL LEAD TO CONFUSION ANDLOSS OF CONTROL, RESULTING IN HOLE DIGGERDAMAGE AND/OR PERSONAL INJURY.

THE CONTROLS ARE DESIGNED FOR THEOPERATOR TO CHOKE AND START THE ENGINEWITH THE LEFT HAND WHILE OPERATING THETHROTTLE CONTROL WITH THE RIGHT HAND.WITH THIS INTENDED OPERATING POSITION, THEENGINE EXHAUST MUFFLER WILL FACEOPPOSITE THAT OF THE OPERATOR. THERESULTING FUMES AND HEAT WILL BEDIRECTED AWAY FROM THE OPERATOR. DO NOTOPERATE THE HOLE DIGGER WITH THE ENGINEEXHAUST MUFFLER/SHIELD FACING TOWARDTHE OPERATOR. THIS OPERATION POSITION WILLALLOW THE OPERATOR TO COME IN CONTACTWITH THE HOT SURFACE OF THE ENGINEMUFFLER/SHIELD AND RESULT IN PROPERTYDAMAGE AND/OR PERSONAL INJURY. IT WILLALSO ALLOW THE OPERATOR TO INHALE HIGHLEVELS OF CARBON MONOXIDE THAT CANRESULT IN PERSONAL INJURY.

STARTING THE ENGINE WITH THE AUGERCONNECTED TO THE TRANSMISSIONDRIVESHAFT.

Application: 240H Hole Digger powered by theHonda GX35 engine.

1) Grass and other overgrowth conditions will hamperthe digging characteristics of any earth auger bybecoming "clogged" around the auger blade and screwbit. Removal of such obstructions from the holelocation will increase digging efficiency and overallproductivity.

2) Place the Hole Digger on the desired hole location.The engine throttle is intended to be controlled by theoperator's right hand. The engine is intended to bestarted by the operator’s left hand. Do not operate theHole Digger with the engine throttle control beingcontrolled by the operator's left hand. The operatorshould position himself on firm footing. FIGURE 3.


FIGURE 3

3) Turn the engine ON/OFF ignition switch to the ONposition. The switch is located near the underside ofthe engine fuel tank. FIGURE 4.

FIGURE 4

4) Depress the engine primer system bulb repeatedlyto feed fuel directly into the carburetor until it can beseen in the clear plastic fuel return line. FIGURE 5.

FIGURE 5

5) If the engine is cold or the ambient temperature islow, move the choke control lever to the left/closedposition (away from the fuel tank) to deploy the enginechoke mechanism. A warm (previously run) enginemay not require choking. FIGURE 6.

Proper operation of the choke lever moves it in asideways movement as viewed by the operator. Donot attempt to move the choke lever in a fore andaft direction. Such action can result in damage tothe choke control mechanism.

FIGURE 6

6) It is not necessary to open the engine carburetorwith the throttle control to start the engine. Grip thethrottle control with the right hand. This procedure is tobe followed regardless of the ambient temperature.


7) Using the left hand, pull the engine starter handleslowly, until resistance is felt. This is the compressionpoint. Return the starter handle to its original positionand pull swiftly. Do not pull the rope out to its maximum,extended length. Repeat as necessary for the engineto start. Allow the starter handle to retract slowly. If theengine does not start after five pulls, stop and consult the material supplied by the enginemanufacturer.

8) Allow the engine to properly "warm up" and operatewithout the requirement for engine choke. As theengine warms up, move the choke lever up to theright/open position (toward the fuel tank). In coldweather, initial starting will require more pulls becausean extremely rich fuel/air mixture is required. Check forproper centrifugal clutch operation, excessivetransmission noise and/or vibration.

9) Stopping the Hole Digger is accomplished byreleasing the twist grip throttle control to its maximum,closed (engine idle speed) position and then turningthe engine ON/OFF ignition switch to the OFF position.The switch is located under the fuel tank.

If the Hole Digger and/or an individualcomponent/accessory does not appear to befunctioning properly, STOP and do not furtheroperate the Hole Digger until the corrective actionhas been completed. If there are any questionsregarding the proper operation of the Hole Digger,contact the dealer or the Customer ServiceDepartment for assistance BEFORE furtherutilization. There is no charge for this service.

OPERATING THE HOLE DIGGER.


1) Do not attempt to begin digging with the Hole Diggeruntil the operator is ready to begin the process and isin full control of the machine.

2) Rotate the twist grip throttle controlcounterclockwise to increase the engine speed. Theauger will begin to rotate when the engine speedreaches the centrifugal clutch initial engagement

speed.

3) Normal operating procedure for the Hole Digger is todig with the engine operating at full speed. This willallow the centrifugal clutch to become more firmlyengaged. This procedure will transmit more usablepower to the auger, resulting in greater productivity andless component wear.

When digging in areas filled with known buriedobstructions such as tree roots, rocks and otherdebris, operate the Hole Digger at less than full (anintermediate) speed to insure a more rapid releaseof the centrifugal clutch when an obstruction isencountered. This is an industry wide operatingprocedure.

4) The Hole Digger is equipped with a centrifugal clutchassembly within the transmission, designed to slipwhenever overloaded or if the auger comes in contactwith a buried obstruction. Newton’s Laws of Physicsallow the centrifugal clutch assembly to ALWAYS slipwhenever overloaded or if the auger comes in directcontact with a buried obstruction. The term slippage isnot intended to infer that the centrifugal clutchassembly becomes fully disengaged with nohorsepower and torque being transmitted to the auger.In the slipping mode, a centrifugal clutch still transmitsa specific amount of horsepower and torque to theauger. This specific amount of horsepower and torqueis directly proportional to many factors including: themechanical condition of the centrifugal clutchassembly and the rotational speed of the centrifugalclutch assembly when the initial slippage occurs. Theresponse time for the centrifugal clutch assembly toreact to an overload condition is directly proportional toits rotational speed. The higher the rotational speed(RPM) of the centrifugal clutch at the time of overload,the greater amount of time it requires to react andactually slip. This phenomenon is inherent with allcentrifugal clutch assemblies. It is also inherent with allpowered equipment incorporating such a device.


STRIKING BURIED OBSTRUCTIONS SUCH ASTREE ROOTS, ROCKS AND OTHER DEBRIS ATANY SPECIFIC ENGINE OPERATING SPEED CANCAUSE THE HOLE DIGGER TO TRANSMITREACTIONARY TYPE "IMPACT" LOADS TO THEOPERATOR. THESE TYPES OF LOADS ARECHARACTERIZED BY A SHARP, PULSATINGMOVEMENT OF THE HOLE DIGGER IN ACOUNTERCLOCKWISE DIRECTION (AS VIEWEDBY THE OPERATOR). SUCH LOADS CAN LEAD TOTHE LOSS OF OPERATOR CONTROL AND RESULTIN PERSONAL INJURY. THE OPERATIONALEFFECTS ARE ALIKE TO THAT OF UTILIZING ACOMMON ELECTRIC DRILL AND OTHER,ROTATION TYPE, POWERED EQUIPMENT. THERELATED PHENOMENON IS INHERENT WITH ALLSUCH TYPES OF ROTATION TYPE, POWEREDEQUIPMENT AND IS TERMED AS KICKBACK.

UNDERSTANDING KICKBACK.


The operation of the Hole Digger involves enginetorque being transmitted and multiplied by thetransmission to the auger. The energy is then used todig holes. But to every force (action), there is always areaction force in the opposite direction. Thus, if theauger contacts a buried obstruction, the operator willfeel the left side of the handle of the Hole Digger being"thrusted" toward him. This "thrusting" forceexperienced by the operator is called kickback. Thespeed that the handle moves (and magnitude of theresulting impact force) is directly proportional to theamount/speed of the kickback force experienced by theoperator. The torque and kickback generated by thedigging process is inherent with a portable, one manHole Digger of this type. The operational effects arealike to that of utilizing a common, electric drill andother, rotation type, powered tools.

BACK CARE/PROPER LIFTING INFORMATION


In addition to kickback forces encountered during thehole digging process, the operator will be required to liftthe Hole Digger and auger/auger extension withnumerous repetition, as demanded by the specific jobapplication. Utilizing proper lifting techniques will

minimize fatigue and back-related injuries whileincreasing overall productivity rates.

ANATOMY

The human body is supported by the spinal column.The spinal column consists of thirty separate bonescalled vertebrae, all linked and supported by a series oftiny muscles. Small pads called discs are situatedbetween each vertebrae and act like shock absorbersto cushion the pressure created from external forces.The spinal column is wrapped by a system of nervesand has three natural curves:

Cervical: from the base of the neck to the brain.Thoracic: situated from the middle to the lower back.Lumbar: located from the lower back to the buttocksarea.

These three curves need to be kept in naturalalignment in order to prevent discomfort.

PREVENTATIVE MEASURES

Most occupational physicians agree on several“universal” preventative measures that an operatorshould follow to help lower the risk of back-relatedinjuries:

1) Maintain proper body weight.

2) Maintain good posture while walking or sitting.

3) Be conscious of how you twist and bend your bodywhile digging. Twisting and bending the wrong way canexert too much pressure on one side of your vertebrae.

4) Always use proper lifting techniques as describedbelow.

5) Develop a consistent exercise routine.

6) Eliminate or reduce your use of tobacco. Smokingreduces the supply of oxygen and nutrients to the discsthat cushion the vertebrae.PROPER LIFTING PROCEDURES

The following are guidelines for properly lifting the HoleDigger and auger/auger extension from the hole and


are not intended to be all inclusive. Plan your path andmake sure there are no obstructions or trippinghazards. Consider how you will set the load. The spinalcolumn is a very sensitive mechanism. At any giventime, improper lifting procedures can cause damagethat can lead to injury.

1) Position your feet at a comfortable distance(shoulder width) to help provide the necessarybalance.

2) Tighten your stomach muscles by pulling in yourstomach. Keep your back as straight as possible tokeep the spine, back muscles and ligaments in correctalignment.

3) Remember to bend at the hips and knees as muchas possible.

4) Start lifting the Hole Digger with a thrust of your feetwhile lifting as much as possible with your leg muscles.Use smooth movements.

5) Once you lift the Hole Digger, keep it close aspossible to the body. Avoid turning at the waist. To turn,pivot your entire body.

6) Keep your shoulders, hips and feet pointed in thesame direction.

7) Keep your footing firm and make sure that yourintended path is clear before attempting to carry theHole Digger.

MINIMIZING KICKBACK FROM AN OPERATIONALSTANDPOINT.


The operator should keep the left side of the handle asclose to his body (left hip and leg areas) as possible tominimize machine "kickback" when a buriedobstruction is encountered by the auger. Assumeoperating positions that allow exercising reactive "bodyenglish" against the torque sensation created by thedigging process. Keep upper arms as close to theupper body as possible to maximize mechanicalleverage. An operator should position his back asvertical as possible by bending the legs as requiredduring the digging process. Positioning the left footahead of the right foot at a comfortable distance willenhance proper body position. Maintaining proper

operating position is one of the most IMPORTANT andEFFECTIVE procedures for controlling kickback.Improper operating positions only aggravate the effectsof kickback upon the operator. FIGURE 7 depicts aproper operator position. FIGURE 8 depicts animproper operator position.

FIGURE 7

FIGURE 8Keep a firm, but steady, grip on the operator handle.Wrap your fingers around the handle and handle gripareas, keeping them cradled between the thumbs andforefingers. REMEMBER- PROPER OPERATOR


POSITIONS ENHANCE THE CONTROL OF THEHOLE DIGGER, REDUCE OPERATOR FATIGUE,AND INCREASE OVERALL PRODUCTIVITY.

Maintain the operator handle and throttle controlhandle grip areas in good condition and free ofmoisture, pitch, oil or grease. Wear gloves toimprove your grip. Bent and damaged handles, athrottle control with a damaged/no grip or handleswithout the gripping area material (PVC coating)aggravate the effects of kickback upon theoperator by limiting control and comfort. Do notoperate the Hole Digger until such damage hasbeen repaired and/or replaced. Damage to propertyand/or personal injury can result.

Always assume that any digging site can includesome form of buried obstruction. Always beprepared for unexpected auger contact with buriedtree roots, rocks, etc. Under certain operatingconditions, striking a buried obstruction canproduce a severe and/or sudden kickback force tothe hip and/or leg areas. It is possible that thiskickback force can have the magnitude to "throw"the operator from the Hole Digger. The operatormust maintain physical and mental alertness andbe prepared to accommodate this phenomenon.Failure to properly accommodate this phenomenoncan result in property damage and/or personalinjury.

IF, DURING THE HOLE DIGGING PROCESS, THEOPERATOR LOOSES FULL CONTROL OF THEHOLE DIGGER FOR ANY REASON, THEFOLLOWING PROCEDURE IS SUGGESTED:

AS A GENERAL RULE, AS SOON AS THEOPERATOR REALIZES HE IS IN THE PROCESS OFLOOSING FULL CONTROL OF THE HOLE DIGGER,HE SHOULD "PUSH" HIMSELF FREE AND CLEARFROM THE OPERATOR HANDLE. THE

PROCEDURE REQUIRES THE OPERATOR TOFULLY COMPREHEND THAT HE IS LOOSINGCONTROL OF THE HOLE DIGGER AND TO REACTACCORDINGLY WITH APPROPRIATE BODYMOVEMENT. IMPROPER REACTIONS TO THISPHENOMENON CAN RESULT IN PROPERTYDAMAGE AND/OR PERSONAL INJURY.

A HOLE DIGGER WITH AN IMPROPERLYMAINTAINED ENGINE THROTTLE CONTROL WILL"SPIN" ABOUT ITS AXIS WHEN THE OPERATORLOOSES FULL CONTROL. IN THE EVENT OF THISOCCURRENCE, DO NOT ATTEMPT TO STOP THEENGINE BY GRASPING THE ROTATINGOPERATOR HANDLE. DO NOT INTRODUCE ANYFOREIGN OBJECT IN AN ATTEMPT TO STOPAND/OR BLOCK THE ROTATING HANDLE.INSTEAD, ALLOW THE ENGINE TO EXHAUST ITSFUEL SUPPLY. DETERMINE THAT ALLCOMPONENTS OF THE ENGINE THROTTLECONTROL ASSEMBLY ALLOW FOR PROPERFUNCTION BEFORE ATTEMPTING TO FURTHERUTILIZE THE HOLE DIGGER.

MINIMIZING KICKBACK FROM A DESIGNSTANDPOINT.


1) The 240H Hole Digger features the widest operatorhandle of any machine in its class. The handle isbiomechanically positioned to enhance control byallowing the operator to exert "body english" againstthe torque and kickback generated by the diggingprocess.

2) The Hole Digger utilizes an antivibration material(PVC coating) that is applied to the operator handleduring the manufacturing process. This material isintended to enhance control and help dampen thetorque and kickback experienced by the operatorduring the digging process.

3) The Hole Digger utilizes a twist grip throttle control.This type of throttle control device was selected overother configurations (for the operator handleconfiguration utilized and specific digging power)


because it allows the operator to wrap his thumbaround the forefinger and effectively maximize thestrength in his right hand. This design feature affordsthe operator greater control of the machine whencounteracting the effects of torque and kickback duringthe digging process.

4) The Hole Digger is designed to utilize the GeneralEquipment Company PN 2121 Auger Pin to retain theearth auger to the transmission driveshaft. This pin isnot intended to shear and absorb kickback relatedforces when the earth auger comes in sudden contactwith a buried object. The pins are utilized for thefollowing reasons:

a) Such an occurrence (pin shear) would result inextensive physical damage to the driveshaft and augerdrive hub.

b) Even if the physical damage to the Hole Diggercould be eliminated and/or minimized from the actualprocess, it could require an unknown (and potentiallylarge) number of auger pins to complete the diggingprocess for any specific hole.

c) Even if the cost of replacement auger pins is not afactor, the resulting productivity produced by the actualprocess would not be deemed acceptable by industryand/or social standards for the Hole Digger.

d) Given the infinite number of soil conditions whichcould be encountered during the actual process, it isimpossible to design and supply a specific auger pin toshear at a specific torque value which would produceacceptable operational results for the Hole Digger.

e) Given the infinite number of potential operators andtheir methods utilized during the actual process, it isimpossible to design and supply a specific auger pin toshear at a specific torque value which would produceacceptable operational results for the Hole Digger.

f) Given the infinite number of combinations of soilconditions, auger diameters, auger boring headconditions, digging depths, mechanical operatingconditions, operators and operator methodsencountered during the actual process, it is impossibleto design and supply a specific auger pin to shear at aspecific torque value which would produce acceptableoperational results for the Hole Digger.

5) For comparison purposes, it is interesting to notethat portable electric drills do not utilize any torquelimiting or clutch device to allow the drill bit to slip atany specific torque value for drilling purposes. As witha Hole Digger, such a device would make the drill auseless tool because of the infinite number of potentialoperating configurations and the inability to designspecific components to meet the requirements of eachoperating configuration.

6) Many portable electric screwdrivers incorporate atorque limiting or clutch device which allows theoperator to preset the torque output of the tool to aspecific value. This is especially useful and desirablewhen hardware can be secured to specific torquevalues according to industry published standards.

7) Portable electric drills and screwdrivers are twoseparate tools designed for different and specific jobapplications. The drilling process has differentrequirements than the fastening process offered byscrewdrivers. The operational characteristics ofportable electric screwdrivers can not be confusedand/or substituted for the operational characteristics ofthe Hole Digger.

OPERATING THE HOLE DIGGER CONTINUED.


5) Auger boring heads are designed for digging in awide variety of soil types and/or conditions. Eachboring head design represents a compromise in overalldigging efficiency, productivity and service life for anygiven soil condition. As a general rule, pressing downon the operator handle is not required to initiate and/orsustain the digging process. In most soils of moderateProctor Densities, augers will dig at rates that will notcause the centrifugal clutch to overload and slip. Inmost soft soils of low Proctor Densities (sandy, etc.), itmay be necessary to hold up on the operator handle toreduce the digging rate of the auger. The naturaltendency of any auger design, in low Proctor Densitysoil conditions, is to dig at a rate which causes thecentrifugal clutch to overload and slip. In most hardsoils of high Proctor Densities (hard clay, etc.), it maybe necessary to press down on the operator handle toestablish and maintain acceptable digging rates.Proper digging procedure for any given soil condition isthe accumulation of actual experience, skill and


common sense. For any given soil condition, allow theauger to dig at the rate most comfortable to theoperator, yet not causing the centrifugal clutch tooverload and slip.

An improper operating procedure can allow theauger to "bind" and/or "bury" itself in the hole. Thisis usually the result of allowing the auger to feed atan excessive rate. This phenomenon is alsocharacteristic of digging with smaller (2 to 4 inch)diameter augers. In this operating condition, theHole Digger is not capable of transmitting amplepower to "free" the auger. Do not continue tooverload and slip the centrifugal clutch assembly.

Damage to property and/or personal injury canresult if the operator looses partial and/or fullcontrol of the Hole Digger while in thisconfiguration. STOP the Hole Digger anddisconnect it from the buried auger. The buriedauger can then be retrieved by various, industryaccepted methods. Contact the Customer ServiceDepartment for specific information. There is nocharge for this service.

6) Some soil conditions may require more power to digthe hole than the Hole Digger is capable of deliveringfor a given auger diameter. This problem is morenoticeable in areas of semiconsolidated soils orcompacted soils having high Proctor Densities.Examples of such soil types include: soft shale, hardpan and cliche. The power required to dig a hole isdirectly proportional to the soil resistance encounteredby the auger and the square of the auger diameter. Forexample: an 8 inch diameter auger requires almost 2times the power than that of a 6 inch diameter, givenidentical soil conditions. This problem is best minimizedby the addition of suitable down force by the operatorand by utilizing augers equipped with new,replacement screw bits and teeth. The manufacturermakes no guarantee that the Hole Digger is capable ofdigging a hole of specific diameter in any given soilcondition. Contact the Customer Service Departmentfor information relative to your specific requirements.There is no charge for this service.

IT IS A MISCONCEPTION THAT A LARGERDIAMETER HOLE CAN BE OBTAINED BY FIRSTDIGGING AN INITIAL HOLE WITH A SMALLER"PILOT" AUGER AND THEN UTILIZING A LARGERDIAMETER AUGER TO "REAM" THE HOLE TO THEDESIRED SIZE. THIS METHOD WILL NOT ALLOWTHE AUGER SCREW BIT TO PRODUCESUFFICIENT DIRECTIONAL STABILITY FOR THELARGER DIAMETER AUGER DURING THE"REAMING" PROCESS. THIS METHOD WILLRESULT IN PROPERTY DAMAGE, LOSS OFOPERATOR CONTROL AND/OR PERSONALINJURY.

7) When digging in areas filled with tree roots, smallrocks or other, buried obstructions, allow the augerblade to "chip away" at the obstruction until the augercan pass by (by working the object loose) or go throughit (as in the case of penetrating tree roots). Thistechnique usually involves holding up on the operatorhandle and establishing a minimal feed rate for theauger. Proper operator position will minimize theeffects of kickback being generated by the auger bladecontacting the object. As with any hole diggingprocedure, the mechanics of this technique require theaccumulation of actual experience and common senseto maximize its effectiveness. Many times the size andnature of the buried object will simply prevent the augerfrom passing by or going through it. Continued use ofthe Hole Digger will only contribute to equipmentdamage and/or personal injury. Instead, remove theburied object with a shovel or other suitable tool andproceed to dig the hole with the Hole Digger to thedesired depth.

Some job applications may encounter buriedobstructions on the job site that are too large insize to allow the usage of a machine such as and/orwith the operating limitations of the Hole Digger.Utilization of the Hole Digger on these job sites cancause property damage and/or personal injury.Exercise proper common sense by selecting theproper size and/or type of equipment for theintended job application.


Some job applications may encounter soilclassifications that are too compacted toallow the usage of a machine the sizeand/or with the operating limitations of theHole Digger. Utilization of the Hole Diggeron these work sites can cause propertydamage and/or personal injury. Exerciseproper common sense by selecting theproper size and/or type of equipment forthe job application.

8) In most soil conditions, the auger will retract withless effort if allowed to rotate at a slow speed. Thisprocedure, however, will leave more loose soil at thebottom of the hole. To minimize the amount of loose soilthat remains at the bottom of the hole, stop the rotationbefore retracting the auger. Proper procedure forobtaining the cleanest, most usable hole for any givensoil condition requires the accumulation of actual skill,experience and common sense.

9) The twist grip throttle controls the digging process byregulating the engine speed. Keep a firm grip on it at alltimes. As with any safety device, it requires constantand proper maintenance to function as intended.

10) Attempting to restart the Hole Digger's engine withthe auger in a partially or completely dug hole requiresextra caution. In this configuration, the throttle controlcan be advanced beyond the idle speed position beforethe operator can exercise proper control of the HoleDigger. The more accepted procedure (when notutilizing the nonflighted auger extension) is to firstremove the unit from the hole and restart the engineaccording to the described method. Return the unit tothe hole with the engine running at idle speed (theauger should not be rotating) and proceed to dig thehole to the desired depth.

Restarting the engine with the auger in a partiallyor completely dug hole requires a higher degree ofoperator experience, skill and common sense overthat of an introductory or novice level of expertise.The manufacturer is aware that many operatorselect to restart the Hole Digger's engine with the

auger in a partially or completely dug hole on aregular basis while in the field. The manufactureralso realizes that this procedure must be utilizedwhen the nonflighted auger extension is utilized toextend the digging depth. The manufacturer has nocontrol over the experience, skill and commonsense levels of each operator of the Hole Digger.The manufacturer has no control over each job siteor specific job application for the Hole Digger.

Individual operator experience, skill, commonsense, job site location and specific job applicationmust affect the final decision on specific operatingprocedures for the Hole Digger. Each operatormust decide if he possesses adequate/properexperience, skill and common sense for operatingthe Hole Digger for any given and/or specific jobapplication.

11) Both the auger blade and screw bit must bereplaced when signs of excessive wear are visible. Aregularly scheduled maintenance program willincrease the service life of the auger and increaseoverall productivity by substantially reducing operatorfatigue. An auger that requires discarding because ofexcessive wear to the blade and screw bit is depictedin FIGURE 9.

Do not utilize an auger with the blade and screw bitworn past their specific service limits. Excessivewear to the blade and screw bit will allow the augerflighting to wear in a tapered or inverted coneconfiguration. The work boring head may actuallybe only capable of digging a hole 60 to 75 percentof the nominal diameter of the auger. Thisconfiguration will allow the auger flighting to“bind” within the hole and substantially reduceoperator control and productivity.


FIGURE 9

12) Avoid placing serious stress to the back and lowerbody members. Always lift in a straight line with yourlegs. Maintain the back in a vertical position as muchas allowed by the digging process. Proper wristposition during the digging process can minimizeand/or reduce stress and strain related damagepotential to this body area. Operator control can beenhanced and fatigue reduced by attempting to keepwrists as perpendicular to the operator handle asfeasible during the digging process. See BACKCARE/PROPER LIFTING PROCEDURES. FIGURE10.

FIGURE 10

13) Stop the engine between each hole to minimize thepossibility of personal injury. Special care must beexercised in slippery conditions and in difficult,overgrown terrain. Store the Hole Digger on the job siteby digging a shallow hole or by disconnecting it fromthe auger and/or nonflighted auger extension. Close

the gasoline tank breather vent (if so equipped) when the Hole Digger is not in use.

STOPPING THE HOLE DIGGER.


Stopping the Hole Digger is accomplished by rotatingthe twist grip throttle control to its maximum, closedposition and allowing the engine to return to its idlespeed. Turn the engine ON/OFF ignition switch to theOFF position. With the throttle control functioningproperly, the engine can be brought to idle speed andthe auger rotation stopped when the throttle controllever is fully closed or suddenly released. If this is notoccurring, check the throttle control, throttle cable,carburetor lever, and engine idle speed for bindingand/or improper adjustment.

TEMPORARY STORAGE FOR THE HOLE DIGGERWHILE ON THE JOB SITE.


The Hole Digger can be temporarily stored on the jobsite by one of three acceptable methods. The chosenmethod is to be determined by the operator basedupon personal preference and/or job site conditions:

a) Digging a shallow hole and leaving the Hole Diggerconnected to the auger with the engine not running.FIGURE 11.


FIGURE 11

b) Disconnecting the Hole Digger from the augerand/or auger extension and storing it in a levelconfiguration. FIGURE 12.

FIGURE 12

c) Storing the Hole Digger while connected only to alead auger with the engine spark plug facing upward.This configuration minimizes the potential for the hotmuffler and/or muffler heat shied area igniting grass orother combustible materials. FIGURE 13.

FIGURE 13

DO NOT STORE THE HOLE DIGGER WITH THEENGINE OPERATING. IMPROPER STORAGEMETHODS CAN RESULT IN PROPERTY DAMAGEAND/OR PERSONAL INJURY.

DO NOT ALLOW THE HOLE DIGGER TO DROPAND IMPACT AGAINST THE GROUND. SUCHACTION CAN RESULT IN DAMAGE TO THE TWISTGRIP THROTTLE CONTROL AND ENGINE. ATHROTTLE CONTROL THAT DOES NOT OPERATEPROPERLY CAN RESULT IN PROPERTY DAMAGEAND/OR PERSONAL INJURY.

ADDING AND REMOVING THE NONFLIGHTEDAUGER EXTENSION.


Many digging jobs require a hole deeper than thatprovided by standard length augers. For many suchrequirements, a nonflighted auger extension isavailable. The nonflighted auger extension extends thedigging depth by an additional 15 inches (381 mm).


Utilization of the nonflighted auger extensionrequires additional operator experience, skill andcommon sense over that of an introductory ornovice level of expertise. The manufacturer has nocontrol over the experience, skill and commonsense levels of each operator of the Hole Digger.Each operator must decide if his experience, skilland common sense level is sufficient to allow himto proceed with the utilization of the nonflightedauger extension for any given and/or specific jobapplication.

Follow this accepted procedure for utilizing thenonflighted auger extension to extend the diggingdepth:

1) Dig to the approximate full depth of the augerutilizing the described operating instructions. Removeas much loose soil from the hole as possible utilizingthe described operating instructions.

2) STOP the engine and remove the auger from thehole. Disconnect the spark plug wire to preventaccidental engine starting. Close the gasoline tankbreather vent (if so equipped).

3) Disconnect and remove the Hole Digger from theauger. Place the auger in the hole. Attach the augerextension to the auger and secure with an auger pin.The Hole Digger can now be connected to the augerextension and secured with an auger pin. Reconnectthe spark plug wire.

4) Follow the instructions outlined for starting andoperating the Hole Digger. Use extra caution whenstarting the Hole Digger's engine with the auger in thehole. Proceed to dig to the desired depth or to the fulldepth of the auger extension.

NEVER UTILIZE MORE THAN ONE NONFLIGHTEDAUGER EXTENSION TO INCREASE THE DIGGINGDEPTH OF THE AUGER. THIS EXTENSION IS NOTEQUIPPED WITH AUGER FLIGHTING TO ELEVATETHE LOOSE BORINGS FROM THE HOLE.CONSEQUENTLY, MULTIPLE USE OFNONFLIGHTED AUGER EXTENSIONS WILL ALLOWTHE AUGER TO "BURY" ITSELF IN THE HOLE.SUCH USE CAN LEAD TO THE LOSS OFOPERATOR CONTROL AND/OR PERSONALINJURY.

After the desired digging depth has been achieved, thenonflighted auger extension is removed by utilizing thisaccepted procedure:

1) Remove as much loose soil from the hole aspossible with the auger rotating at an intermediatespeed. STOP the engine and disconnect the spark plugwire to prevent accidental engine starting. Close thegasoline tank breather vent (if so equipped).

2) Lift the auger extension and the Hole Digger up farenough out of the hole so that the auger extension isclear. Block the remaining auger with an auger fork toprevent it from falling back into the hole. Disconnect theHole Digger from the auger extension. Remove theauger extension and auger from the hole. FIGURE 13.

3) Reconnect the engine spark plug wire.

FIGURE 13


THE PROCEDURE OUTLINED FOR THE USE OFTHE NONFLIGHTED AUGER EXTENSION OFFERSTHE MOST ADAPTABLE METHOD OF EXTENDINGTHE DIGGING DEPTH FOR THE WIDEST CROSSSECTION OF PROBABLE OPERATORS. THISPROCEDURE TAKES INTO ACCOUNTANTICIPATED OPERATOR EXPERIENCE, SKILLAND COMMON SENSE. THE MANUFACTURER ISAWARE THAT NOT ALL OPERATORS WILL ELECTTO FOLLOW THIS PROCEDURE. THEMANUFACTURER HAS NO CONTROL OVERINDIVIDUAL OPERATION PROCEDURES AND/ORDECISIONS. MANY OPERATORS MAY ELECT TOUTILIZE THE NONFLIGHTED AUGER EXTENSIONCONNECTED DIRECTLY TO THE AUGER ANDBYPASS THE LONGER, MORE TIME CONSUMINGPROCEDURE OUTLINED ABOVE. INDIVIDUALOPERATORS MAY ELECT TO CHOOSE OTHERPROCEDURES IN AN EFFORT TO REDUCE THEASSOCIATED PRODUCTION COSTS. THERESULTING MACHINE CONFIGURATIONS CANPLACE THE HANDLE ALMOST LEVEL WITH (OREVEN ABOVE) THE SHOULDERS OF THEOPERATOR. AT THIS HEIGHT LEVEL, THE HOLEDIGGER IS DIFFICULT TO CONTROL AGAINSTPOSSIBLE KICKBACK FORCES. THIS IS NOT AMANUFACTURER APPROVED PROCEDUREBECAUSE IT REQUIRES EACH POTENTIALOPERATOR TO HAVE EXCEPTIONAL HEIGHT ANDEXPERT WORK EXPERIENCE, SKILL ANDCOMMON SENSE. UNFORTUNATELY, THERE ISSTILL NO REAL ASSURANCE THAT EACH ANDEVERY OPERATOR WITH EXCEPTIONAL HEIGHTAND EXPERIENCE, SKILL AND COMMON SENSECAN ALWAYS EXERCISE ADEQUATE CONTROLOF THE HOLE DIGGER TO GUARANTEEPERSONAL SAFETY. PERSONAL SAFETY CANNEVER BE GUARANTEED FOR ANY GIVENAND/OR SPECIFIC JOB APPLICATION FOR ANYTYPE OF POWERED EQUIPMENT. THE ACCEPTEDPROCEDURE, AS OUTLINED IN THIS OPERATOR'SMANUAL, IS STRONGLY RECOMMENDED. THEMANUFACTURER CAN NOT CONDONE AND/ORAPPROVE ANY OTHER PROCEDURE.

CHANGING THE HOLE DIGGER TRANSMISSIONLUBRICANT.


Tools Required:

1 each, 7/16 inch wrench1 each, #2 Phillips head screwdriver1 each, torque wrench, 120 inch pounds (13.5 N.m.)

capacity with 7/16 inch socket1 each, rubber hammer

Parts Required:

1 each, PN 240-0100 gasket.1 each, PN 210-0720 grease packet or 8 ounces(224g) of high temperature transmission or marine-grade, wheel bearing grease classified for extremepressure (EP) applications. Fisk Brothers (Lubriplatebrand) GR132 is an approved lubricant.

The 240 Hole Digger utilizes a fully enclosed, doublereduction transmission for multiplying and transmittingengine torque to the auger. The principle involvesengine horsepower and torque being transmittedthrough a centrifugal clutch and two sets of gearreductions into a final driveshaft. Grease is provided forlubrication and heat dissipation for the bearings, gearsand clutch assembly.

A pressure relief valve, PN 5677, is located on the topsurface of the transmission cover to relieve any excesspressure created in the transmission due to heat rise.Should this valve become plugged, the followingproblems can occur:


a) Lubrication grease can be forced out between thebearings and the final driveshaft.

b) The gasket that separates the two halves of thetransmission can push out, causing a loss of lubricationgrease.

The potential for these problems can be minimized bycleaning the pressure relief valve at regular intervalswith an approved safety solvent. The transmission isshipped from the factory filled with approximately 8ounces (224g) of high temperature lubricant. Thislubricant contains an extreme pressure additive whichis designed to cling to the gear teeth at high rotationalspeeds.

1) Change the transmission lubricant every 50 hours ofoperation, or more often as necessary, if the HoleDigger is operated in extremely dusty or dirtyconditions.

2) Drain the fuel from the fuel tank into a UL® approvedcontainer. Wipe any excess spilled fuel and dispose ofproperly. Refer to the Service section for more detailedinformation.

3) Position the Hole Digger on a suitable work benchwith the operator handle level with the ground. As analternative, the transmission driveshaft can be securelymounted in a suitable bench vice. Wipe any dust or dirtfrom the area where the transmission separates.

GASOLINE IS AN EXTREMELY FLAMMABLE FUEL.USE EXTREME CAUTION WHEN HANDLINGGASOLINE. DO NOT SMOKE OR BRING FIRE ORFLAME NEAR THE FUEL.

4) Loosen and remove the six capscrews that fastenthe transmission together. Using the rubber hammer,split and separate the transmission cover and case.Exercise caution not to damage the dowel pins locatedon opposite ends of the transmission.

5) If the bearing journals of the secondary pinion, PN210-0310, are difficult to remove from the ball bearings,the transmission cover and case will separate withgreater difficulty. It maybe necessary to provide asupplemental force to the pinion journals to assist the

removal process. Remove the PN 37040200 Screwfrom both bearing housings. Insert a 1/4-20 UNCcapscrew of one inch minimum length into the housing.Using the wrench, turn the capscrew in a clockwisedirection. This will provide thrust against the pinionbearing journal until it clears the pinion gear supportbearing. Repeat the process with the remaining piniongear bearing journal if necessary. FIGURE 14. Removethe PN 210-0100 gasket. Remove the primary gearand pinion assembly, PN 210-0340 and PN 210-0310.NOTE: THIS PROCESS IS ONLY NECESSARY IFTHE FIT BETWEEN THE PINION GEAR JOURNALSAND THE BALL BEARINGS DO NOT ALLOWDISASSEMBLY OF THE TRANSMISSION COVERAND CASE.

FIGURE 14

6) Clean the interior surfaces of the transmission coverand case with an approved safety solvent.

7) Clean each gear with an approved safety solvent.Inspect the teeth for excess wear, cracks or fatigue.Replace each component as necessary.

Observe all applicable safety precautions for thesolvent. Dispose of the used transmissionlubricant according to all applicable laws andregulations.

8) If necessary, reinstall PN 37040200 Screw into thebearing housings. Properly secure with the providedhardware.


9) Fill the transmission cover and case with 8 ounces(224g) of high temperature transmission greasecontaining an extreme pressure additive. Part Number210-0720 lubrication grease or Fisk Brothers GR-132is an approved lubricant. FIGURE 15. If the FiskBrothers lubricant can not be readily sourced, anacceptable alternative is a marine-grade wheel bearinggrease that contains an EP (denoting extremepressure) additive. Distribute the grease equally aroundall gear teeth. Do not utilize standard lithium basedgreases intended for common lubrication purposes.These types of grease are not formulated to operate atthe higher operating temperatures encountered duringthe hole digging process. Such greases also do notcontain an extreme pressure additive for use withgears.

FIGURE 15

10) Reinstall the primary gear and pinion assembly.Distribute the grease equally around all gear teeth.Replace the old transmission gasket with a new gasket,PN 240-0100. Align the transmission dowel pins whenreinstalling the cover. Reinstall the fasteners with thehexagon nuts on the cover side of the transmission.Torque all fasteners to 96 in lbs (12 N.m.) in an “X"sequence.

11) Rotate the final driveshaft and check for excessivenoise and/or binding. If excessive noise and/or bindingis evident, disassemble the transmission andinvestigate for probable causes. Reassemble andretorque to the specified amount. Recheck forexcessive noise and/or binding.

12) Inspect the Hole Digger for loose, worn ordamaged parts. Replace any questionable part orassembly with a genuine, approved replacement part.

Do not attempt any maintenance or repair work notdescribed in the Operator Manual. Have such workperformed at your dealer's servicing shop.

MAGURA® THROTTLE CONTROL MAINTENANCEPROGRAM.

Applications: All 200 Series models.

The Magura twist grip throttle controls engine speedduring the actual hole digging process. It has proven tobe a rugged, dependable device that deliversexceptional service life while requiring only minimalmaintenance. Every 8 hours of actual operation andwhenever the throttle cable is replaced, the followingmaintenance program is to be followed:

1) Remove the plastic cover to properly inspect theinternal components. Any worn or damagedcomponent should be replaced with a factory approvedreplacement part only. FIGURE 16.

2) Normal use will produce a wear pattern by thebraided inner cable into the idler pulley. Maximumallowable groove depth wear created by the throttlecable is 0.045 inch (1 mm). A wear depth in excess ofthis limit will require the replacement of the idler pulley.

3) Inspect the braided inner cable on a regular basis forexcessive wear and fraying in the area in direct contactwith the idler pulley. Abnormal wear or fraying willrequire the replacement of the throttle cable.

FIGURE 16

4) Inspect the barrel end of the braided inner cable forproper retention on a regular basis. A properly retainedbarrel end will have no relative movement between itand the inner cable. Any relative movement will requirethe replacement of the throttle cable. FIGURE 17.


FIGURE 17

5) Inspect the receptacle area of the throttle controlwhich retains the barrel end of the braided inner cableon a regular basis. A properly fitted barrel fitting shouldhave complete freedom of movement with no bindingrestrictions or excessive play due to wear. A barrelfitting which is binding within the receptacle should bediscarded in favor of a replacement throttle cable.Excessive receptacle wear will require replacement ofthe specific component assembly. FIGURE 18.

FIGURE 18

6) The rubber boot assembly is designed to protect theinternal components of the throttle control fromexcessive foreign material accumulations. The servicelife of the boot assembly can be extended with theapplication of an appropriate preservative on a regularbasis.

Do not operate the Hole Digger without a rubberboot assembly in proper condition mounted inposition on the Magura throttle control. Without theuse of a proper rubber boot assembly, foreignmaterials can accumulate within the throttle controlassembly. Such an occurrence can restrict themovement of the internal components, reducingoperator control of the Hole Digger and result inproperty damage and/or personal injury.

7) If a regular inspection of the throttle controldetermines the carburetor return spring does notproperly return the throttle control to the idle position,remove the throttle tube from the operator handle.Further inspect the tube and the operator handlesurface area for an accumulation of foreign material,including dirt, moisture, etc. Remove any accumulationand clean as necessary. It is not necessary to providean external lubrication to this area during thereassembly process. FIGURE 18

8) Inspect the handle grip on a regular basis todetermine it is properly secured to the throttle control.A grip which fits loose on the throttle control or hasbecome worn or torn from use should be replaced witha factory approved replacement part only.

AUGER MAINTENANCE PROGRAM.


All General 200 Series Hole Diggers utilize earthaugers incorporating a boring head configurationfeaturing the E-Series, knife-type blades. This designhas been field proven for several decades to provideunequaled digging performance in a wide rangeof unconsolidated and semiconsolidated soilformations. As with any ground engaging tool, theservice life of the wear components will have limitsdirectly affected by soil classification, soil moisturecontent and general operating procedures. Aconsistent auger maintenance program will providemaximum digging performance and investmentreturn.

CENTRIFUGAL CLUTCH ROTOR AND SHOEASSEMBLY REMOVAL AND INSTALLATION.


The 240 Hole Digger utilizes an all metal centrifugalclutch rotor and shoe assembly that expands withengine RPM to engage the clutch drum and transfertorque. The centrifugal clutch rotor and shoe assemblyis mounted to and operates concentrically about theengine crankshaft. Symptoms for replacement of theclutch assembly include the following:

1) Excessive clutch slippage and auger stalling at fullengine speed.

2) Partial clutch engagement (and resulting augerrotation) at the specified engine idle speed.


To replace the clutch rotor and shoe assembly, proceedas follows:

Tools required:

1 each, 7/16 inch wrench.1 each, 17 mm socket with impact wrench1 each, container of Locktite 609 or equivalent 1 each, torque wrench, 120 inch pounds (13.4 N.m.)capacity and 17 mm socket.

Parts Required:

1 each, PN 240 0100 transmission gasket (if required)1 each, PN 240-0160 drum and pinion shaft assembly(if required)1each, PN 240-0170 rotor and shoe assembly

Centrifugal clutch removal and installation will require alevel working platform of sufficient size and appropriateheight. As an alternative, the transmission driveshaftassembly can be securely mounted in a suitable benchvice.

The transmission is designed to allow removal of aworn centrifugal clutch rotor and shoe assemblywithout requiring the transmission cover and case to bedisturbed. Upon inspection, if the centrifugal clutchdrum and pinion shaft requirement replacement, thetransmission case and cover will then require furtherdisassembly.

1) Drain the fuel from the fuel tank and oil from theengine into UL® approved containers. Wipe any excessspilled liquids and dispose of properly. Refer to theService section for more detailed information.

GASOLINE IS AN EXTREMELY FLAMMABLE FUEL.USE EXTREME CAUTION WHEN HANDLINGGASOLINE. DO NOT SMOKE OR BRING ANY FIREOR FLAME NEAR THE FUEL.

2) Using the 7/16 inch wrench, remove the four K-locktype nuts that retain the engine to the transmission.Separate the engine from the transmission.

3) Position the engine with the rotor and shoe assemblyfacing up and properly secured.

4) Using the impact wrench and 17 mm socket, removethe two retaining capscrews. Threads are right handed.Remove the rotor and shoe assembly from the engineflywheel.

5) Clean the engine flywheel and clutch drum areaswith an appropriate solvent.

Observe all applicable safety precautions for thesolvent.

6) Inspect the engine flywheel, crankcase castings,mounting studs and clutch drum for cracks and othersigns of visible of damage. Any damaged componentwill require immediate replacement with a suitable,factory-replacement part.

7) If the clutch drum shows signs of severe wear and/ordamage, it will also require immediate replacement.Refer to CENTRIFUGAL CLUTCH DRUM ANDPINION SHAFT REMOVAL AND INSTALLATION.Severe wear is defined as:

a) Deep grooves cut into the walls of the drum thatmeasure greater than 3.140 inches (79.76 mm).

b) A deep, dark blue color that might indicate sustainedoperation at high temperatures while slipping.Extended and sustained operation can potentiallyweaken the structural integrity of the brazed connectionbetween the drum and pinion shaft.

8) Clean and inspect the hardware that retains the rotorand shoe assembly to the engine flywheel. Replaceany component with a factory approved replacementpart if cracks and other signs of visible damage arepresent.

9) Apply Locktite 609 or equivalent to the shoulder boltthreads.

10) Locate the replacement clutch rotor and shoeassembly and thrust washers on the engine flywheel withthe direction arrow pointing in a counter-clockwisedirection. FIGURE 19. This orientation properly maximizesthe torque transmitting capabilities of the clutch.


FIGURE 19

Improper orientation will result in increasedslippage, reduced digging capacity with increasedclutch wear.

11) Install the retaining shoulder bolts. Torque theshoulder bolts to 5.4-7.2 ft. lbs. (7.5-10 N.m.). Whenproperly installed and torqued, the shoulder boltsshould not thrust directly against the washers and thusapply a direct force against the clutch shoes. Such anoccurrence will restrict the proper movement of theclutch shoes.

Improper shoulder bolt clearance will limit propermovement of the clutch shoes and overalloperation. Such an occurrence can result inproperty damage and/or personal injury.

12) Reinstall the engine to the transmission with thecorrect orientation to the operator handle.

IMPROPER ENGINE MOUNTING ORIENTATION TOTHE OPERATOR HANDLE CAN REDUCE MACHINECONTROL DURING THE HOLE DIGGINGPROCESS. SUCH OCCURRENCE CAN RESULT INPROPERTY DAMAGE AND/OR PERSONALINJURY.

13) Using the wrench, tighten the 1/4 inch K-lock typenuts. There is not adequate space to allow the use of aconventional torque wrench. Tighten the nuts toapproximate a 90 inch pound (10 N.m.) value. Anapproximate value will place the nut flush with the endof the mounting studs.

14) Rotate the final driveshaft and check for excessivenoise and/or binding. If excessive noise and/or bindingis evident, disassemble the engine from thetransmission and investigate for probable causes.Reassemble and retorque to the specified values.Recheck again for excessive noise and/or binding.

15) Refill the engine fuel tank and crankcase with theappropriate fluids as required.

16) If placing the machine back in service, follow theprocedures as outlined in this manual for starting theengine. Refer to STARTING THE ENGINE WITH THEAUGER CONNECTED TO THE TRANSMISSIONDRIVESHAFT.

8) Inspect the support bearings for excessive wear.Replace as necessary. Install the replacement drumand shaft assembly in the transmission cover.Determine the drum fits tight against the bearings.

9) Apply a suitable amount of tread anti-seize materialto the exterior threads of the drum shaft. Reinstall thepinion gear, PN 210-0320 to the drum shaft. Thread byhand. If additional torque is required, the pinion gearcan be assembled to the shaft utilizing the impactwrench and the 12 point, 25/32 inch socket. Thread thepinion gear on the shaft until it fits tight against thebearing. A thrust force that places an excessive preloadagainst the bearing is not necessary and can actuallyreduce bearing service life.

10) Reinstall the primary gear and pinion assembly.Determine there is sufficient grease equally spreadaround all gear teeth. Replace the old transmissiongasket with a new gasket, PN 240-0100. Align thetransmission dowel pins when reinstalling the cover.Reinstall the fasteners with the hexagon huts on thecover side of the transmission. Torque all fasteners to96 inch lbs (12 N.m.) in an “X” sequence.

11) If necessary, reinstall PN 37040200 Screw into thebearing housings. Properly secure with the providedhardware.

12) Rotate the final driveshaft and check for excessivenoise and/or binding. If excessive noise and/or bindingis evident, disassemble the transmission andinvestigate for probable causes. Reassemble andretorque to the specified value. Recheck for excessivenoise and/or binding.

13) Inspect the centrifugal clutch assembly forexcessive wear and/or damage. If it is determined thecentrifugal clutch rotor and shoe assembly requiresreplacement, refer to CENTRIFUGAL CLUTCHROTOR AND SHOE ASSEMBLY REMOVAL ANDINSTALLATION in the Service section of this manualfor additional information.

14) Reinstall the engine and operator handle to thetransmission. Torque the fasteners to 90 inch lbs (10N.m.) in an “X” sequence.

15) Refill the engine crankcase with the correct amountand type of grease. Refer to FILLING THE ENGINECRANKCASE WITH OIL in the Before Starting theEngine section of this manual for additionalinformation.

16) Determine that the disassembly process has notaffected the proper operation of the twist grip throttlecontrol. If improper operation is detected, determinethe probable cause(s). Replace any suspectcomponent with a factory approved replacement partonly.
