These safety alert symbols identify important safety messages in this manual. When you see these symbols, be alert to the possibility of personal injury and carefully read the message that follows.

Do not allow anyone to operate the Hole Digger without first reading this Operator Manual and becoming familiar with its operation. The manufacturer of this Hole Digger has gone to great extremes to provide the owner(s) and/or operator(s) with the finest equipment available for its intended job function of digging vertical holes in unconsolidated and specific semiconsolidated earth formations. Yet, the possibility exists that the Hole Digger can be utilized in and/or subjected to job applications not perceived and/or anticipated by the manufacturer. Such misuse and/or misapplication of the Hole Digger can lead to the possibility of serious damage, injury or even death. It is the responsibility of the owner(s) and/or operator(s) to determine that the Hole Digger is being utilized and/or operated within the 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 the Hole 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) to determine that no modifications and/or alterations have been made to the Hole Digger.

Modifications and/or alterations can lead to the possibility of serious damage, injury or even death. It is the responsibility of the owner(s) and/or operator(s) to make this Operator Manual available for consultation during all phases of operation. Refer to OSHA 2207 and/or applicable updated revisions which contains all OSHA job safety and health rules and regulations (1926 and 1910) covering construction.

The concept of portable, one and two man, hole digging equipment has been successfully utilized for many 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. Use of a Hole Digger requires strenuous


,


work activity. This type of work activity can be considered to be greater in magnitude than that experienced with the use of many other types of both light construction and lawn and garden related equipment. This type of work activity should only be attempted by operators of adequate physical size and stature, mental awareness and physical strength and condition. The body parts most noticeably affected during the hole digging process are the arms, hands, wrists, shoulders, lower back and legs.

The process can also produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body parts. Back and wrist related pain can be side effects of utilizing a Hole Digger. A potential operator with a chronic back related problem or a history of back and/or other medically related problems should not attempt to utilize the Hole Digger. Use of the Hole Digger may only aggravate this and any other medically related problem. Because of the diverse type of prevailing job applications, job site conditions, operator experience levels and operator physical characteristics, no warranty, guarantee, representation and/or liability is made by the manufacturer as to the absolute correctness or sufficiency of any operational procedure, operational position and/or technique. There is no absolute guarantee that an operator of any given experience level, physical size and/or physical condition will be immune to the possibility of and/or probable physical side effects of the normal use of the Hole Digger. Each potential operator must be made aware of and assume the operational and physical liability described and/or associated with the use of the Hole Digger. Improper use of the Hole Digger can result in property damage and/or personal injury, including death. Each potential operator not willing to assume the operational and physical liability described and/or associated with the use of the Hole Digger, should not operate it. Proper levels of operator experience, skill and common sense are essential for maximizing the safe and efficient operation of the Hole Digger

3) Determine that the Hole Digger is in its original, factory configuration and has not been modified in any manner. Many modifications can result in potentially dangerous configurations that can lead to property damage and/or personal injury. If there are any questions about possible modifications made to the

Hole Digger, contact the Customer Service Department for specific information BEFORE utilization. There is no charge for this service.

INCORRECT USE OF THE HOLE DIGGER CAN

RESULT IN PROPERTY DAMAGE, PERSONAL

INJURY OR EVEN DEATH. TO REDUCE THIS

POSSIBILITY, GIVE COMPLETE AND UNDIVIDED

ATTENTION TO THE JOB AT HAND AND FOLLOW

THESE SAFETY PRECAUTIONS:

4) Minors should never be allowed to operate the Hole

Digger. Bystanders, especially children and animals, should not be allowed in the area where the Hole

Digger is in use. The hole digging process can result in flying particles being emitted at high velocity and striking the operator and/or onlookers. This can lead to the possibility of property damage and/or personal injury. Keep all body parts, loose clothing, foreign objects and onlookers clear of the rotating auger and/or auger extensions.

PREPARATION.

1) The 300 Series Hole Diggers are a specialized type of powered equipment, designed for a specific job function and requires adequate and thorough instruction BEFORE it is operated. The size, power, complexity and operating characteristics of this type of powered equipment would dictate that each operator must receive adequate, professional instruction regarding the proper operation of this Hole Digger before being allowed to utilize it. BEFORE attempting to utilize this Hole Digger, read this Operator's Manual, the

5) Operators must be in proper physical condition, mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Working with the Hole

Digger is strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor BEFORE operating the Hole Digger. Guard against the possibility of back related injuries. Always lift the Hole Digger with leg muscles and not with the back.

Operators must be of adequate height so that for any given operating configuration, the operator handle(s) remain below their shoulder sockets. Do not operate the Hole Digger if this condition is not satisfied. The 300


,


Series hole Diggers require that both operators be of similar height, weight and strength to maximize digging efficiency and minimize the possibility of personal injury. Both operators share the burden associated with the hole digging process.

and related accessories are not classified as being insulated. Contact with buried electrical cables, gas lines and other hazardous items can result in electrocution and/or an explosion.

6) Prolonged use of the Hole Digger (or other, similar machines) exposes the operator to vibrations which may produce Whitefinger Disease (Raynaud's

Phenomenon). This phenomenon reduces the hand's ability to feel and regulate temperature, produces numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.

Antivibration systems do not guarantee that you will not sustain Whitefinger Disease. Therefore, continuous and regular users should closely monitor the condition of their hands and fingers. After each period of use, exercise to restore normal blood circulation. If any of the symptoms immediately.

appear, seek medical advice

7) Clothing must be sturdy and snug fitting, but allow complete freedom of movement. Never wear loose fitting jackets, scarves, neckties, jewelry, flared or cuffed pants or anything that could become caught on controls or moving parts. Wear long pants to protect your legs. Protect your hands with heavy duty, nonslip gloves to improve your grip. Good footing is most important when operating the Hole Digger. Wear sturdy boots with nonslip soles. Steel-toed safety shoes are highly recommended. Keep shoes properly laced.

Never wear tennis shoes or other, similar type shoes which afford little or no protection. Wear an approved safety hard hat to protect the operator'(s') head(s) where there is a danger of head injuries. Noise, generated by the engine of the Hole Digger and the actual process itself, can damage your hearing. Wear approved sound barriers (ear plugs or ear mufflers) to protect your hearing. Continuous and regular operators should have their hearing checked regularly.

10) Know how the controls operate. Know how to stop the engine quickly in an emergency. Always start the engine according to the instructions as outlined in this manual to minimize the possibility of unexpected or uncontrolled auger rotation. Unexpected auger rotation can cause loss of machine control, and the possibility of property damage and/or personal injury.

11) Never exceed the recommended capacities of the

Hole Digger. Refer to the Specifications section of this manual for more detailed information. Always utilize the correct auger and auger extension series designed for use with the Hole Digger. Some Hole Diggers can utilize specially designed augers intended for drilling holes through ice. Such an auger will find limited success when utilized to dig earth. Earth augers are not designed to drill through ice. Use of an incorrect auger or auger series can result in property damage and/or personal injury.

12) The 300 Series Hole Digger are powered by gasoline engine which produce Carbon Monoxide fumes during the combustion process. Carbon

Monoxide fumes are poisonous. Breathing Carbon

Monoxide fumes while operating the Hole Digger can result in property damage and/or personal injury. The normal operation of the Hole Digger is outdoors where the potential effects of Carbon Monoxide to the operators are minimized. If the Hole Digger is operated in a closed area (indoors or outdoors), determine if supplemental ventilation is required to minimize the potential effects of Carbon Monoxide to the operators.

Follow all current OSHA regulations pertaining to ventilation.

OPERATION.

8) Visually inspect the Hole Digger, auger(s), auger extension(s), and accessories for damaged or worn parts. Inspect each auger for the proper screw bit and teeth. Look for loose and/or damaged handle grips.

Check for loose and/or broken parts. Determine that operator controls work freely, all safety devices are operative and information/safety decals are readable.

Check to determine that the Hole Digger and all related accessories are

BEFORE utilization.

in good mechanical condition

1) Give complete and undivided attention to the job at hand. Do not chew gum, smoke and/or use smokeless tobacco while utilizing the Hole Digger. Do not attempt to eat and/or drink while utilizing the Hole Digger.

Determine that eyeglasses, hearing aid devices and other medical related devices are properly secured.

Keep shoes properly laced. Use of the Hole Digger is strenuous and causes fatigue. Help prevent the cause of an accident. Plan to take work breaks as required to help maintain proper mental and physical alertness.

9) Contact appropriate representatives to determine if/where electrical cables, gas lines and other hazardous items are buried under the work surface

BEFORE utilization. Some Hole Diggers feature operator handles constructed of a non metallic, composite material. Use of this material does not guarantee the operators will be properly insulated from contact with charged electrical cables. The Hole Digger

2) The 300 Series Hole Diggers are not sealed or insulated. Do not operate any Hole Digger in an explosive atmosphere or near combustible materials.

Refer to current OSHA rules and regulations.

3) Gasoline is an extremely flammable fuel. Use extreme caution when handling gasoline or mixing


,


fuel. Always utilize UL®, CSA® OR CE approved containers for the storage and transportation of fuel.

Do not smoke or bring fire or flame near the fuel.

Always shut off the engine and allow it to cool before refueling. Never remove the fuel tank filler cap while the engine is running. Never operate an engine without a fuel tank filler cap. Select bare ground for fueling and move at least 10 feet from the fueling spot before starting the engine. Wipe off any spilled fuel before starting the engine and check for leakage. If a fuel or oil leak is found, do not start or run the engine until the leak is fixed and the spillage has been wiped away. Take care not to get fuel or oil on your clothing.

If this happens, change your clothing immediately.

Before operating the Hole Digger refer to the

Specifications section of this manual for more detailed information regarding fuel and lubrication requirements.

Always hold the operator handles firmly with both hands. Wrap your fingers around the handles, keeping them cradled between your thumbs and fingers. Always determine the operator handles are in good condition and free of moisture, pitch, oil or grease. Wear gloves to improve your grip. Never leave the Hole Digger running unattended.

9) Stop the engine between each hole. Allowing the engine to remain operating between each hole substantially increases the potential for property damage and/or personal injury. Special care must be exercised on slippery conditions and on difficult, uneven surfaces. Watch for cracks, high spots and other, surface irregularities. Keep proper footing and balance at all times. The normal use of this machine is on level surfaces. Other terrains can be dangerous and should be avoided. Only properly trained operators should attempt these techniques.

4) The 300 Series Hole Diggers are designed for use by two operators. Use of the Hole Digger by one or more than two operators can lead to confusion and loss of control, resulting in property damage and/or personal injury. Never operate the Hole Digger with an improper number of operators. Such a configuration can result in property damage and/or personal injury. If it is felt that more than two persons are required to furnish additional "down pressure" to the auger, STOP and contact the Customer Service Department for specific operational and service/maintenance information.

There is no charge for this service.

10) The 300 Series Hole Diggers are designed to be started by both operators in the following manner: the

Crew Chief regulates engine speed (RPM) with the engine throttle control while the Crew Member starts the engine by use of the recoil starter. The Crew Chief is responsible for the necessary verbal commands.

Never operate a 300 Series Hole Digger if it requires one of the operators to operate the engine throttle control, carburetor choke system and the engine recoil starter (or any combination) at the same time. This is not a factory designed operating configuration for the

Hole Digger. Such configuration(s) will result in loss of machine control, property damage and personal injury.

Contact the Customer Service Department for information relative to restoring the Hole Digger to its original configuration BEFORE further utilization. There is no charge for this service.

5) Do not operate the Hole Digger with onlookers close by. Caution all onlookers to stand clear. The hole digging process can result in flying particles being emitted at high velocity and striking the operator and/or onlookers. This can lead to the possibility of property damage and/or personal injury. Keep all body parts, loose clothing and foreign objects clear of the rotating auger.

6) Do not utilize a shovel and/or foreign object to remove loose soil from around the hole area while the

Hole Digger is in use. Such a practice can result in the shovel and/or foreign object to become entrapped by the rotating auger, leading to property damage and/or personal injury.

7) Start the engine according to the instructions as outlined in this manual to minimize the possibility of unexpected auger rotation. Unexpected auger rotation can result in the loss of machine control and the possibility of property damage and/or personal injury.

8) Start and operate the Hole Digger only in a well ventilated area. Carbon Monoxide fumes given off by an engine are poisonous. Breathing these fumes can result in property damage and/or personal injury.

Operate the Hole Digger only when/where visibility and light are adequate for the job at hand. Work carefully.

11) Contact with a hot, engine muffler can cause property damage and/or personal injury. Remain clear of a hot engine muffler. Do not over speed the engine by altering the governor setting or by disconnecting the engine governor. Serious damage to the engine and/or personal injury can result.

12) The 300 Series Hole Digger are powered by gasoline engines which produce Carbon Monoxide fumes during the combustion process. Carbon

Monoxide fumes are poisonous. Breathing Carbon

Monoxide fumes while operating the Hole Digger can result in property damage and/or personal injury. the normal operation of the Hole Digger is outdoors where the potential effects of Carbon Monoxide to the operators are minimized. If the Hole Digger is operated in a closed area (indoors or outdoors), determine if supplemental ventilation is required to minimize the potential effects of Carbon Monoxide to the operators.

Follow all current OSHA regulations pertaining to ventilation.

13) Because this Hole Digger is classified as a low


,


cost, hand held, low horsepower, portable type machine, it is limited in the number of practical and/or suitable job applications. A particular job site, actual surface conditions, job specifications and operator skill/common sense may dictate that a different type of machine (with characteristics of higher purchase cost, being mounted to a carrier vehicle, with greater horsepower and less mobility), method and/or process be utilized to properly complete the job with the degree of efficiency and safety required. Contact the Customer

Service Department for specific information regarding suitable job applications, job site surface conditions and operator experience/skill/common sense recommendations for the Hole Digger BEFORE utilization. There is no charge for this service.

MAINTENANCE, REPAIR AND STORAGE.

1) Use only genuine, approved replacement parts and accessories for maintenance and repair. Use of parts and accessories manufactured by others can result in property damage and/or personal injury.

2) Follow the Service instructions as outlined in the appropriate section of this manual.

operated if the muffler is faulty or has been removed.

Contact with a hot engine muffler can cause property damage and/or personal injury.

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

8) The Hole Digger may utilize self locking type hexagon head nuts to minimize the effects of vibration.

Replace all self locking hardware with genuine, factory approved, replacement parts only.

9) Consult the material supplied by the engine manufacturer for specific information relative to proper operational, lubrication and storage requirements.

10) Replace the auger teeth and screw bit when signs of excessive wear are seen. When such components are not replaced at proper intervals, excessive wear will occur at the boring head and auger flighting. The end result is an inverted cone configuration for the auger which usually requires complete replacement. FIGURE

1. Digging with augers that are past their useful service life or that have not been properly maintained can result in substandard productivity, excessive property damage and/or personal injury. Auger service life can be greatly extended with a consistent auger maintenance program.

3) Always stop the engine and disconnect the spark plug wire BEFORE checking or working on the Hole

Digger.

4) Always properly maintain the Hole Digger.

Frequently check all fasteners and individual parts.

Built in safety features are effective only if they are maintained in good working condition. Replace any questionable part or assembly with a genuine, factory approved, replacement part. Do not forsake proper maintenance for the price of a few replacement parts.

Proper maintenance does not cost...it actually pays dividends. Do not attempt any maintenance repair work not described in this manual. Have such work performed at your dealer's service facility.

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

6) A worn or damaged engine muffler is a fire hazard and may cause loss of hearing. Check to see that the muffler is in good condition. If the muffler is equipped with a spark arresting device, determine that it is in proper working condition at regular service intervals.

Replace the spark arresting device with an approved replacement if there is any question of its integrity. It is the responsibility of the owner(s) and/or operator(s) to provide for and properly maintain a USDA approved, spark arresting muffler in an operating area specified by law. Check with appropriate governing agencies for more specific information. The Hole Digger must not be

SAFETY

AND/OR

AND

PERSONAL

1) The Honda GXV140 engine incorporates a multipurposed carburetor/throttle arm design that allows it to be utilized with both Bowden (push) and braided wire (pull) type configurations. For simplicity, productivity and service reasons, the Hole Digger incorporates a braided wire (pull) type configuration. A magura® twist grip throttle control is utilized as the engine speed control device. The Magura® throttle control has proven to be a rugged, dependable device that delivers exceptional service while requiring only minimal service.

10) Rotate the throttle control counterclockwise (the maximum speed position) to determine that the inner wire pulls the throttle lever of the carburetor forward, against its stop. Improper adjustment will not allow the engine to operate at its maximum, no load, governed speed and affect the overall digging performance of the

Hole Digger. Adjust the swivel assembly and throttle cable attach bracket as necessary to allow for

2) The GXV140 engine utilizes one or two spring loaded screws as stops for the carburetor throttle arm.

a) If equipped, the shorter (inner) screw is non functional for this application.


,


b) The longer (outer) screw is factory set to prevent the engine from operating in an overspeed configuration.

As set at the factory, the GXV140 engine will operate at approximately 3800/3900 RPM no load. In a no load configuration the engine is operating at maximum governed speed without an earth auger attached to the transmission driveshaft.

Do not alter the position of the spring loaded screw that regulates maximum engine speed.

An improper setting can result in excessive engine speed leading to damage, substandard digging performance and loss of operator control that can result in property damage and/or personal injury.

3) The GXV140 engine may utilize a forced idle type governor spring to provide the proper engine idle speed. With the spring system in proper operation, the engine will normally idle at 1500/1600 RPM. An improper spring system or use of an applicable engine without the spring properly attached will not allow the engine to operate at the specified idle speed. FIGURE

General Equipment Company transmission and Engine

Oil, PN 999-11, or a high grade, SAE 30 Detergent or

10W30 motor oil into th transmission though the oil filler/level plug opening. Use only an oil marked with an engine service classification SF, SG, or SH/CD. As a general rule, the transmission is usually filled with the same oil type and weight that is utilized in the applicable 4-Cycle engine crankcase. FIGURE 34.

Filling the engine crankcase with oil will require a level working platform of sufficient size and appropriate height. As an alternative, the transmission driveshaft can be securely in a suitable bench vise.

1) Wipe any dust or dirt from the crankcase

3) The transmission oil level is to be maintained at the bottom of the oil filler/level plug hole. Allow any excess


,


oil to drain out of the transmission. This procedure determines the correct oil level for the transmission.

Correct oil level is important to insure proper centrifugal clutch operation. Maintaining the oil level too high will cause excessive centrifugal clutch slippage and result in high oil temperature. Excessive slippage and high oil temperature will significantly reduce the service life of the clutch assembly and affect the overall performance of the Hole Digger.

4) Inspect the oil filler/level plug gasket for proper security. If necessary, replace the gasket with a factory approved replacement part only. Reinstall the oil filler/level plug. Tighten securely with the adjustable wrench. Wipe off any excess oil spilled on the transmission. Properly dispose of the spilled oil.

INFORMATION RELATIVE TO COMPOSITE

MATERIAL OPERATOR HANDLES


.

The Hole Digger may utilize operator handles constructed of a specially designed, composite material intended to reduce machine weight and help absorb the shock loads transmitted to the operators during the digging process. This material has shown to be very durable and will offer a very acceptable service life. However, it will not tolerate the same amount of external damage as steel tubing without some sacrifice of its appearance and/or physical strength properties. Protect the handles from external sources of damage. Do not allow the handles to come in contact with augers, shovels, or other sharp and abrasive objects during transit. Do not stack or throw similar objects on the handles during storage. Keep the handles clean and free of dirt, moisture, grease, oil and other, foreign material accumulations.

Exercising proper preventative maintenance for the handles will result in an extended service life.

1) Operator handles are constructed from a composite material with a demonstrated high dielectric constant.

This insulating characteristic alone does not guarantee that contact with a buried electrical cable will not allow energy to be transmitted directly to the operators. Other factors reducing the insulating characteristics of the operator handle configuration include, but are not limited to: a) Throttle cable. The throttle cable connects directly to the engine according to the design offered by the specific engine manufacture. The throttle cable is manufactured from conductive type materials for strength and durability purposes. This allows energy to flow from the auger through the engine and directly to the Magura throttle control.

b) Throttle control. The Magura throttle control is fabricated from aluminum and plastic. There is no guarantee the design configuration will eliminate energy being transmitted from the throttle cable, through the throttle control and directly to the operator.

c) External condition of the operator handles.

Accumulation of moisture, dirt, pitch and other foreign substance can provide a conductive pathway for energy to be transmitted from the exterior of the operator handle and directly to the operator. It is recommended that operator handles be maintained in a clean, dry condition and free of all foreign materials.

2) The composite material is formulated by its manufacturer with an inhibitor to reduce (but not eliminate) the long term effects of ultra violet radiation from the sun. However, it is still recommended the composite material operator handles be protected from ultra violet radiation whenever possible to extend their service life.

3) Composite material operator handles are coated with a clear, polyurethane finish to help protect from external damage and abuse. When performing preventative maintenance on the Hole Digger, the protective covering can be restored by lightly sanding the handle surface with 240 grit sandpaper and then applying two thin coats of clear polyurethane.

ELSEWHERE IN THIS OPERATOR MANUAL.

Wear all appropriate safety apparel and equipment when utilizing the sandpaper and clear polyurethane spray.

Follow all appropriate safety precautions for the use of these materials.


,


4) A composite material operator handle with a cut or abrasion greater than 0.125 inch (3.2 mm) deep must be removed from service and replaced with a factory approved replacement part only.

5) Do not operate the Hole Digger without the proper handle reinforcement properly transmission case sockets.

Handle reinforcements provide proper structural integrity. Use of the Hole Digger without the proper operator handle reinforcement can result in property damage and/or personal injury.

6) Do not utilize chains or slings wrapped around the composite material operator handles to help remove a

Hole Digger which has become stuck in the ground.

GENERAL TRANSPORTATION INFORMATION.

Application: All models.

When transporting the Hole Digger in/on a motor vehicle, the gasoline tank breather vent (if so equipped) must be completely closed to eliminate the accidental seepage of fuel and resulting potential fire hazard. In order to minimize the possibility of damage to the Hole Digger, always transport it to the job site with the auger disconnected. Failure to properly transport the Hole Digger can cause transmission oil to become entrapped in the centrifugal clutch assembly.

Such an occurrance can cause excessive clutch slippage until the oil properly drains. All equipment must be secured in/on vehicles with suitable strapping or tie downs. Personnel should not be transported in the same compartment as equipment and fuel supplies. Consult applicable OSHA regulations.

1) The Hole Digger is designed for two operators to transport it by the operator handles to, while on, and from the job site. Connect the auger to the Hole Digger with the correct factory supplied auger pin. Depending upon the specific model, a variance in auger pin part number and design configuration exists. Models 310,

310F, 330, 330B, 330H, 356F, 357H, 330T and 357T utilize the 3/8 inch (9.5mm) diameter, PNG 2121 auger pin. Models 324F, 343B, 343H and 343T each utilize the 5/16 inch (7.9mm) diameter, PNG 2021 auger pin.

FIGURE 36.

The factory supplied auger pin is designed to withstand the high stresses encountered while digging. Use of any other connecting device, including cap screws, bolts, pins, etc., can result in damage to the Hole Digger driveshaft and/or auger drive hub. Improper connecting devices can cause property damage and/or personal injury.

When installing the auger and auger pin, always place the Hole Digger with the engine spark plug in the upward position to minimize the potential for gravity to allow oil and/or gasoline to enter into the combustion chamber and create a hydraulic lock up. Such an occurrence can result in property damage and/or personnel injury.

1) Grass and other overgrowth conditions will hamper the digging characteristics of any earth auger by becoming "clogged" around the auger teeth and screw bit. Removal of such obstructions from the hole location before attempting to dig will increase digging efficiency and overall productivity.

2) Place the Hole Digger in a vertical orientation on the desired hole location. The operators should position themselves on firm footing.

Then, he gives a fast, short, steady pull. Allow the starter rope to retract slowly. If the engine does not start after three pulls, stop and consult the information supplied by the engine manufacturer for specific information. As the engine warms up, the Crew Member moves the choke lever to the full open position.

7) Normally an engine that has not been run for some time requires three to five pulls before it will fire. On the other hand, a recently run engine will usually start on the first or second pull. In cold weather, initial starting will require additional pulls because an extremely rich fuel/air mixture is required.

8) Allow the engine to properly "warm up" and operate without the requirement for engine choke. Check for proper centrifugal clutch operation, excessive transmission noise and/or vibration.

9) Stopping the Hole Digger is accomplished by rotating the twist grip throttle control clockwise to its maximum, closed (engine idle speed) position. The

Crew Member then turns the ignition ON/OFF switch to the OFF position. The Crew Chief turns the fuel value to the OFF position. FIGURE 39.

OPERATING THE HOLE DIGGER.


1) Do not attempt to begin digging with the Hole Digger until both the Crew Chief and Crew Member have acknowledged to each other that they are ready and are in full control of the machine.

2) The Crew Chief rotates the throttle control counterclockwise to increase the engine speed. The auger will begin to rotate when the engine speed reaches the centrifugal clutch initial engagement speed.

3) Normal operating procedure for the Hole Digger is to dig with the engine operating at full, governed speed to allow the centrifugal clutch to become more firmly engaged. This procedure will transmit more usable power to the auger, resulting in greater productivity and less component wear.


,


When digging in areas filled with known, b u r i e d o b s t r u c t i o n s s u c h a s t r e e r o o t s , rocks and other debris, operate the Hole

T h i s i s a n industry wide operating procedure.

4) The Hole Digger is equipped with a centrifugal clutch assembly within the transmission. Newton's Law of

Physics allow the centrifugal clutch assembly to

ALWAYS slip whenever overloaded or if the auger comes in contact with a buried obstruction. The response time for the centrifugal clutch assembly to react to an overload condition is directly proportional to its 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 and actually slip. This phenomenon is inherent with all centrifugal clutch assemblies. It is inherent with all powered equipment incorporating such a device.

UNDERSTANDING KICKBACK.

APPLICATIONS: ALL MODELS.

operating positions that allow each to exercise reactive

"body english" against the torque sensation created by the digging process. Keep upper arms as close to the upper body as possible to maximize mechanical leverage. Operators should position their backs as vertical as possible by bending the legs as required during the digging process. Positioning the left foot ahead of the right foot will enhance proper body position. Maintaining proper operating positions is one of the most IMPORTANT and EFFECTIVE procedures for controlling kickback. Improper operating positions only aggravate the effects of kickback upon the operators. FIGURE 49 depicts proper operator positions that enhance machine control. FIGURE 50,

FIGURE 51 and FIGURE 52 depict improper operator positions that reduce machine control .

The operation of the Hole Digger involves engine torque being transmitted and multiplied by the transmission to the auger. The energy is then used to dig holes. But to every force (action), there is always a reaction force in the opposite direction. Thus, if the auger contacts a buried obstruction, the operators will feel the left side handles of the Hole Digger being

"thrusted" towards them. This "thrusting" force experienced by the operators is called kickback. The speed (and magnitude of the resulting impact force) at which the auger strikes the buried object is directly proportional to the amount/speed of the kickback force experienced by the operators. The torque and kickback generated by the digging process is inherent with a portable, two man Hole Digger and can not be eliminated by any operation and/or design characteristic The operational effects are alike to that of utilizing a common, electric drill and other, rotation type, powered tools.

MINIMIZING KICKBACK FROM AN OPERATIONAL

STANDPOINT.

FIGURE 49


FIGURE 50

Both operators should keep the left side handle as close to their body (left hip and leg areas) as possible to minimize machine "kickback" when a buried obstruction is encountered by the auger. Assume


,


Handle grips should be repaired and/or replaced when they become worn and/or damaged from use. Do not operate the Hole

Digger until such handles are repaired and/or replaced. Damage to property and/or personal injury can result.

FIGURE 51

Always assume that every digging site can include some form of buried obstruction.

Always be prepared for unexpected auger contact with buried tree roots, rocks, etc.

Under certain operating conditions, striking a buried obstruction can produce a severe and/or sudden kickback force to the hip and/or leg areas. Operators must maintain physical and mental alertness and be prepared to accommodate this phenomenon.

Failure to properly accommodate this phenomenon can result in property damage and/or personal injury.

DESIGN MINIMIZING KICKBACK FROM A

STANDPOINT.


1) The Hole Digger features the longest operator handles of any machine of its type and/or class. These handles are biomechanically positioned to enhance control by allowing the operators to exert "body english" against the torque and kickback forces generated by the digging process.

2) The Hole Digger utilizes antivibration handle grips on the operator handles to enhance control and help dampen the torque and kickback experienced by the operators during the digging process.

FIGURE 52

Keep a firm, but steady, grip on the operator handles.

Wrap your fingers around the handle grips, keeping the grips cradled between the thumbs and forefingers.

REMEMBER PROPER OPERATOR POSITIONS

REDUCE OPERATOR FATIGUE AND INCREASE

OVERALL PRODUCTIVITY.

Maintain the operator handles and grips in good condition and free of moisture, pitch oil or grease. Wear gloves to improve your grip.

Bent or damaged handles, or handles with damaged and worn and/or without grips aggravate the effects of kickback upon the operators by limiting control and comfort.

Do not operate the Hole Digger if the handle grips are worn and/or damaged from use.

Replace the handle grips with factory approved replacement parts only.

3) The Hole Digger features operator handles constructed of a non metallic, composite material. The physical characteristics of this material allow it to help dampen the torque and kickback experienced by the operators during the digging process.

4) The Hole Digger utilizes a twist grip throttle control.


,


This type of throttle control device was selected over other configurations (for the operator handle configuration utilized and specific digging power) because it allows the operator to wrap his thumb around the forefinger and effectively maximize the strength in his right hand. This design feature affords the operator greater control of the machine when counteracting the effects of torque and kickback forces during the digging process.

5) The Hole Digger is designed to utilize the General

Equipment Company part number 2121 pin to retain the earth auger to the transmission driveshaft. This pin is not intended to shear when the auger comes in sudden contact with a buried object.

operating configurations and the inability to design specific components to meet the requirements of each operating configuration.

7) Many portable electric screwdrivers incorporate a torque limiting or clutch device which allows the operator to preset the torque output of the tool to a specific value. This is especially useful and desirable when hardware can be secured to specific torque values according to industry published standards.

8) Portable electric drill and screwdrivers are two separate tools designed for different and specific job applications. The drilling process has different requirements than the fastening process offered by screwdrivers. The operational characteristics of portable electric screwdrivers can not be confused and/or substituted for the operational characteristics of the Hole Digger.

The pins are utilized for the follwoing reasons: a) Such an occurrence (pin shear) would result in extensive physical damage to the driveshaft and auger drive hub.

OPERATING THE HOLE DIGGER CONTINUED.


b) Even if the physical damage to the Hole Digger could be eliminate and/or minimized from the actual processes, it could require an unknown (and potentially large) number of auger pins to complete the digging process for any specific hole.

c) Even if the cost of the replacement auger pins is not a factor, the resulting productivity produced by the actual process would not be deemed acceptable by industry and/or social standards for the Hole Digger.

d) Given the infinite number of soil conditions which could be encountered during the actual process, it is impossible to design and supply a specific auger pin to shear at a specific torque value which would produce acceptable operational results for the Hole Digger.

e) Given the infinite number of operators and their methods utilized during the actual process, it is impossible to design and supply a specific auger pin to shear at a specific torque value which would produce acceptable operational results for the Hole Digger.

f) Given the infinite number of combinations of soil conditions, auger diameter, auger boring head condition, digging depth, mechanical operating condition, operators and operator methods encountered during the actual process, it is impossible to design and supply a specific torque value which would produce acceptable operational results for the

Hole Digger.

5) Auger boring heads are designed for digging in a wide variety of soil types and/or conditions. Each boring head design represents a compromise in overall digging efficiency, productivity and service life for any given soil condition. As a general rule, pressing down on the operator handles is not required to initiate and/or sustain the digging process. In most soils of moderate Proctor Densities, augers will dig at rates that will not cause the centrifugal clutch to overload and slip. In most soft soils of low Proctor Densities

(sandy, etc.), it may be necessary to hold up on the operator handles to reduce the digging rate of the auger. The natural tendency of any auger design, in low

Proctor Density soil conditions, is to dig at a rate which causes the centrifugal clutch to overload and slip. In most hard soils of high Proctor Densities (hard clay, etc.), it may be necessary to press down on the operator handles to establish and maintain acceptable digging rates. Proper digging procedure for any given soil condition is the accumulation of actual experience, skill and common sense. For any given soil condition, allow the auger to dig at the rate most comfortable to the operators (exercising correct operating positions), yet not causing the centrifugal clutch to overload and slip.

6) For comparison purposes, it is interesting to note that portable electric drills do not utilize any torque limiting or clutch device to allow the drill bit to slip at an specific torque value for drilling purposes. As with a

An improper operating procedure can allow the auger to "bind" and/or "bury" itself in the hole. This is usually the result of allowing the auger to feed at an excessive rate. This phenomenon is also characteristic of digging with smaller diameter (2 to 4 inch) augers. In this condition, the Hole Digger is not capable of transmitting ample power to free

the auger. Do not continue to overload and slip the centrifugal clutch assembly. Excessive heat can be created by the slippage resulting in clutch component failure.

6) Some soil conditions may require more power to dig the hole than the Hole Digger is capable of delivering for a given auger diameter. This problem is more noticeable in areas of semiconsolidated soils or compacted soils having high Proctor Densities.

Examples of such soil types include: soft shale, hard pan and caliche. The power required to dig a hole is directly proportional to the soil resistance encountered by the auger and the square of the auger diameter. For example: a 12 inch diameter auger requires 4 times the power than that of a 6 inch diameter, given identical soil conditions. This problem is best minimized (but not eliminated) by the addition of suitable down force by the operators and by utilizing augers equipped with new, replacement screw bits and teeth. Contact the

Customer Service Department for information relative to your specific requirements. There is no charge for this service.

7) When digging in areas filled with small tree roots, small rocks or other buried obstructions, allow the auger teeth to "chip away" at the obstruction until the auger can pass by (by working the object loose) or go through it (as in the case of penetrating tree roots).

This technique usually involves holding up on the operator handles and establishing a minimal feed rate for the auger. Proper operator position will minimize the effects of kickback being generated by the auger teeth contacting the object. As with any hole digging procedure, the mechanics of this technique require the accumulation of actual experience and common sense to maximize its effectiveness. Many times the size and nature of a buried object will simply prevent the auger from passing by or going through it. Continued digging with the Hole Digger will only contribute to equipment damage operator fatigue and/or injury. Instead, remove the buried object with a shovel or other suitable tool and proceed to dig the hole with the Hole Digger to the desired depth.

8) In most soil conditions, the auger will retract with less effort if allowed to rotate at a slow speed. This procedure, however, will leave more loose soil at the bottom of the hole. To minimize the amount of loose soil that remains at the bottom of the hole, stop the


,


rotation before retracting the auger. Proper procedure for obtaining the cleanest, most usable hole for any given soil condition requires the accumulation of actual skill, experience and common sense.

9) The twist grip throttle controls the digging process by regulating the engine speed. Keep a firm grip on it at all times. As with any safety device, it requires constant and proper maintenance to function as intended.

10) Attempting to restart the engine with the auger in a partially or completely dug hole requires extra caution.

In this configuration, the throttle control can be advanced beyond the idle speed position before the two operators can exercise proper control of the Hole

Digger. The more accepted procedure (when not utilizing both nonflighted and/or full flighted auger extensions) is to first remove the unit from the hole and restart the engine according to the described method.

Return the unit to the hole with the engine running at idle speed and proceed to complete the hole to the desired depth.

Do not utilize an auger with the auger teeth a n d s c r e w b i t w o r n p a s t t h e i r s p e c i f i c service limits. Excessive wear to the auger teeth and screw bit will allow the auger flighting to wear in a tapered or inverted cone configuration. The worn boring head may actually be only capable of digging a hole 60 to 75 percent the nominal diameter of the auger This configuration will allow the auger to "bind" within the hole and substantially reduce operator control and productivity.

12) Avoid placing serious stress to the back and other lower body members. Always lift in a straight line with your legs. Maintain the back in a vertical position as allowed by the digging process. Proper wrist position during the digging process can minimize and/or reduce stress and strain related damage potential to this body area. Operator control can be enhanced and fatigue reduced by attempting to keep wrists as perpendicular to the operator handles as feasible during the digging process. FIGURE 54

Tools Required:

1 each, small, adjustable wrench

1 each, small, clean funnel with a flexible extension spout

Changing the transmission oil will require a level working platform of sufficient size and appropriate height. As an alternative, the transmission driveshaft can be securely mounted in a suitable bench vise.


,


1) Change the transmission oil every 25 hours of operation, or more often as necessary, if the Hole

Digger is operated in extremely dusty or dirty conditions.

2) Wipe any dust or dirt from the oil filler/level plug and oil drain plug areas of the transmission. The oil filler/level plug is located on the side of the transmission and is appropriately marked. The oil drain plug is located under the transmission. Remove both plugs with the adjustable wrench and allow the oil to completely drain from the transmission into a suitable container. Replace the oil drain plug and tighten securely with the adjustable wrench. Dispose of the used oil per accepted procedures.

component should be replaced with a factory approved replacement part only. FIGURE 60.

2) Normal use will produce a wear pattern by the braided inner cable into the idler pulley. Maximum allowable groove depth wear created by the throttle cable is 0.045 inch (1 mm). A wear depth in excess of this limit will require the replacement of the idler pulley.

3) Inspect the braided inner cable on a regular basis for excessive wear and fraying in the area in direct contact with the idler pulley. Abnormal wear or fraying will require the replacement of the throttle cable.

3) Using the funnel, pour 1 US quart (0.94 lit) of

General Equipment Company Transmission and

Engine Oil, PNG 999-11, or a high grade, SAE 30

Detergent or 10W30 motor oil into the transmission through the oil filler/level plug opening. Use only an oil marked with an engine service classification SF, SG or

SH/CD. The oil level in the transmission is to be maintained at the bottom of the oil filler/level plug hole.

Allow any excess oil to drain out of the transmission.

This procedure determines the correct oil level for the transmission. Correct oil level is important to ensure proper centrifugal clutch operation. Maintaining the oil level too high will cause excessive clutch slippage and result in high oil temperatures. Excessive slippage and high oil temperatures will significantly reduce the service life of the clutch assembly and affect the overall performance of the Hole Digger.

4) Replace the oil filter/level plug. Tighten securely with the adjustable wrench. Wipe off any excess oil spilled on the transmission. Dispose of the used oil properly.

FIGURE 60

4) Inspect the barrel end of the braided inner cable for proper retention on a regular basis. A properly retained barrel end will have no relative movement between it and the inner cable. Any relative movement will require the replacement of the throttle cable. FIGURE 61.

5) Inspect the Hole Digger for loose, worn or damaged parts. Replace any questionable part or assembly with a genuine, approved factory replacement part only. Do not attempt any maintenance or repair work not described in the Operator Manual. Have such work performed at your dealer's servicing shop.

THROTTLE CONTROL MAINTENANCE

PROGRAM.


The Magura twist grip throttle controls engine speed during the actual hole digging process. It has proven to be a rugged, dependable device that delivers exceptional service life while requiring only minimal maintenance. Every 8 hours of actual operation and whenever the throttle cable is replaced, the following maintenance program is to be followed:

1) Remove the aluminum cover to properly inspect the internal components.

Any worn or damaged

FIGURE 61


,


5) Inspect the receptacle area of the throttle control which retains the barrel end of the braided inner cable on a regular basis. A properly fitted barrel fitting should have complete freedom of movement with no binding restrictions or excessive play due to wear. A barrel fitting which is binding within the receptacle should be discarded in favor of a replacement throttle cable.

Excessive receptacle wear will require replacement of the specific component assembly. FIGURE 62.

A grip which fits loose on the throttle control or has become worn or torn from use should be replaced with a factory approved replacement part only.

AUGER MAINTENANCE PROGRAM.


All General 300 Series Hole Diggers utilize earth augers incorporating the Pengo® type boring head configuration. This design has been field proven for several decades to provide unequaled digging performance in a wide range of unconsolidated and semiconsolidated soil formations. As with any ground engaging tool, the service life of the wear components will have limits directly affected by soil classification, soil moisture content and general operating procedures. A consistent auger maintenance program will provide maximum digging performance and investment return.

REPLACING A WORN AUGER SCREW BIT.

Applications: All augers.

Tools Required:

2 each, 1/2 inch wrenches.

Parts Required:

1 each, PN SB25 Screw Bit (for use with all augers with the exception of the 3 and 4 inch nominal diameter augers).

1 each, PN SB35 Screw Bit (for use with 3 inch nominal diameter earth auger).

1 each, PN SB45 Screw Bit (for use with 4 inch nominal diameter earth auger).

Note: Tungsten Carbide hardfaced versions (SB25C,

SB35C and SB45C) of each applicable screw bit are available. A screw bit hardfaced with Tungsten Carbide will not increase the overall productivity rates of a specific auger equipped with the standard screw bit.

The Tungsten Carbide hardfacing will substantially increase the anticipated service life of a screw bit.

1) The replacement of the auger screw bit will require a level working platform of sufficient size and appropriate height.

2) Inspect the auger for worn or broken components.

Check to determine that the auger does not have a bent or damaged axle. A bent or damaged axle will cause the auger to "wobble" during use. Maximum allowable auger wobble is 0.25 inch (7 mm) total indicated runout (TIR). An auger with a total indicated runout wobble in excess of this value should be removed from service and scrapped.

BASIC INFORMATION.


The 300 Series Hole Diggers utilize a fully enclosed, double reduction transmission for multiplying and transmitting engine torque to the auger. The principle involves engine horsepower and torque being transmitted through a centrifugal clutch and two sets of gear reductions into a final driveshaft. Oil is provided for lubrication and heat dissipation for the bearings, gears and clutch assembly.

The principal variance which exists between specific models occurs in five areas:

1) Engine configuration (2 or 4 Cycle).

2) Transmission cover configuration (2 or 4 Cycle).

3) Centrifugal clutch configuration (designed for either

2 or 4 Cycle engines).

4) Driveshaft configuration (General, Ground Hog or

Stihl).

5) Primary gear configuration (2 or 4 Cycle). FIGURE

66.

FIGURE 66

Other major components are equally shared between all 300 Series Hole Diggers, including operator handles, throttle control, transmission case and bearings.

A pressure relief valve, PN 5677, is located on the top surface of the transmission cover to relieve any excess pressure created in the transmission due to heat rise.

Should this valve become plugged, the following problems can occur:

1) The final driveshaft oil seal can push out of its housing, causing a loss of transmission oil.

2) The gasket that separates the two sections of the transmission can push out, causing a loss of transmission oil.

The potential for these problems can be minimized by cleaning the pressure relief valve at regular intervals.

Oil leakage between the final driveshaft and the oil seal is the result of the following problems:

1) The oil seal is worn due to extended operation.

2) The inner sealing lip of the oil seal is cut or nicked due to the admission of foreign material or some sharp, abrasive object.

3) A replacement oil seal was incorrectly installed in the transmission.

In all cases, a replacement oil seal must be correctly installed to prevent loss of transmission oil. The oil seal, a NATIONAL® PN 471820, is an industry interchange standard and can usually be obtained from local supply sources to help reduce downtime.

HANDLING GASOLINE. DO NOT SMOKE OR

BRING FIRE OR FLAME NEAR THE FUEL.

3) Using the plastic hammer, split and separate the transmission cover and case. Exercise caution not to damage the alignment dowel pins. Place the engine and transmission cover assembly in an upright position in a suitable area. Do not damage the throttle cable.

Remove the primary gear and pinion gear assembly.

4) Clean the transmission case with an appropriate solvent.

Observe all applicable safety precautions for the solvent.

5) Remove the self-locking nut, PN 19100001 (if powered by a Subaru, Briggs & Stratton or Tecumseh engine) or PN 19160001 (if powered by a Honda engine), and flat washer, PN 17100000 (if powered by a Subaru, Briggs & Stratton or Tecumseh engine) or

PNG 17160000 (if powered by a Honda engine).

6) Using the gear puller, remove the secondary gear,

PNG 345-0350 from the driveshaft. Remove the

Woodruff key, PN 15, and the Nilos ring, PN

08125/08231B-AV.

7) Using the shop press and suitable blocking, support the driveshaft housing area of the transmission case to prevent deformation damage. Press the driveshaft out of the transmission. The oil seal should also press out at this time. FIGURE 67.

FIGURE 67

Wear safety glasses and other appropriate s a f e t y e q u i p m e n t w h e n p r e s s i n g t h e driveshaft assembly. Caution all onlookers about the possibility of flying debris and the potential for personal injury.

8) Remove the bearing cone, PNG 08125, from the shaft. Inspect the driveshaft for chipping or cracking around the Woodruff key area.

If any damage is evident, replace the driveshaft.

9) Inspect the area where the oil seal rotates about the driveshaft for scratches, chips or other imperfections which can cause oil to leak past the oil seal. Unless the inner sealing member of the replacement oil seal turns on a concentric, smooth surface, it also will continue to leak oil. If the depth of the groove cut into the final driveshaft is greater than .010 inch (0.25 mm), the driveshaft must be replaced.

10) Inspect the replacement oil seal for cuts or other imperfections around the sealing members. Pack the cavity between the inner and outer sealing members with a Barium or Lithium based lubricating grease.

LUBRIPLATE 105 is an approved lubricant. This precautionary measure minimizes the possibility of a dry oil seal rotating on a dry shaft during the first few minutes of operation. FIGURE 68.

FIGURE 68

11) Slide the oil seal over the circular spacer of the driveshaft with a circular, twisting motion. The crimped side of the oil seal, marked "NATIONAL 471820 USA" faces away and opposite the threaded end of the driveshaft. Use caution not to cut or nick the sealing lips when installing the oil seal.

12) Clean and inspect both bearing cones. Replace if excessive wear is evident. Repack both bearings with a suitable wheel bearing grease. Reinstall the lower bearing cone on the driveshaft against the spacer.

13) Clean and inspect the transmission oil seal housing for damage. If the housing shows signs of "galling" damage or elongation, coat the outside diameter of the oil seal with a bearing locking grade of anaerobic adhesive/sealant to help retain it in position.

14) Position the transmission case on the shop press with the driveshaft housing face up. Determine that the transmission case is not being supported by the alignment dowel pins. Use Service Tool PNG 345-

7010, to press the oil seal/driveshaft assembly into the transmission until the oil seal is firmly seated against the machined shoulder. Cocking the seal in the housing contributes to oil seal failure. The tool is approximately

2.431 inches (61.7 mm) outside diameter. The inside diameter of the tool is approximately 2-1/4 inches.

Apply the face of the service tool to the crimped bead of the oil seal, inasmuch as pressure too close to the center of the seal will distort or damage it. FIGURE 69.

Check to determine the flat washer is tight against the secondary gear and it, in turn, is seated against the Nilos ring. If not fully seated, use a thin, wooden block and a plastic hammer to tap the gear down into place.

UNDER NO

CIRCUMSTANCES SHOULD THE SECONDARY

GEAR RECEIVE DIRECT BLOWS FROM A STEEL

HAMMER. Tap both ends of the driveshaft with a plastic hammer to help set the bearings. Loosen the

5/8 inch (if equipped), self-locking nut and retorque to

25 foot pounds (34 N.m.). Loosen the 1-1/4 inch selflocking nut (if equipped) and retorque to 60 foot pounds

(81 N.m.). Again check to determine the flat washer is tight against the secondary gear. Tap both ends of the driveshaft with a plastic hammer to help set the bearings.

17) Attach the torque wrench and 15/16 inch socket to the 5/8 inch self-locking nut (if equipped) and rotate slowly.

Attach the torque wrench and 1-7/16 inch socket to the 1-1/4 inch (if equipped) self-locking nut and rotate slowly. A MAXIMUM bearing drag of 30

INCH POUNDS (3.4 N.m.) is permitted. This value should allow a MAXIMUM of .003 inch (0.076 mm) freeplay in the bearings. A greater amount of bearing drag will significantly decrease the load capacity of the bearings and contribute to premature bearing failure.

Adjust the torque value of the self-locking nut to yield a bearing drag within the allowable limit. THE FLAT

WASHER MUST BE TIGHT AGAINST THE

SECONDARY GEAR AND THE GEAR TIGHT

AGAINST THE NILOS RING TO PREVENT

DRIVESHAFT FREEPLAY THAT EXCEEDS THE

ALLOWABLE LIMIT. If the bearing drag value is less than or greater than the 30 inch pound (3.4 N.m) figure readjust the self-locking nut torque value accordingly to help produce the desired value. FIGURE 71.

FIGURE 70

15) Reinstall the upper bearing cone, Nilos ring and

Woodruff key on the final driveshaft. Coat the Woodruff key area of the driveshaft with light oil or with the

Barium or Lithium based lubricant. Reinstall the secondary gear and flat washer.

(0.076 mm), relative to the crankshaft itself. Replace the crankshaft assembly if it is not within this established limit.

8) Clean the surface of the crankshaft with an appropriate solvent.

FIGURE 76

11) Install the washer, PN 200682, on the transmission driveshaft. Apply a small amount of high temperature, anti-seize compound to the pinion gear journal area of the driveshaft. Install the replacement PN 3516 clutch drum and pinion assembly on the driveshaft.

12) Reinstall the primary gear and pinion assembly. If the existing transmission gasket is damaged, replace with PN 310-0101 gasket. Align the transmission dowel pins when reinstalling the cover. Torque all fasteners to

20 foot pounds (27 N.m.) in an "X" sequence.


14) Fill the transmission with oil. Refer to the Service section for the correct amount and type.


9) Install the replacement PN 330-0170 clutch rotor and shoe assembly on the engine crankshaft with the hub, including the two set screws, toward the crankcase. Tighten with the 1/8 inch Allen wrench.

FIGURE 75. The end of the crankshaft fits flush against the edge of the clutch rotor and shoe assembly. FIGURE 76.

10) Using the 3/16 inch Allen wrench, replace the Allen type access screw into the side of the transmission cover. Apply a wicking grade of anaerobic adhesive to the Allen screw. This will eliminate the screw from moving during operation of the Hole Digger.

Storage


Proper procedure for long term storage of the Hole

Digger will protect it against the affects of corrosion and damage. If the Hole Digger is not to be operated for a period of 30 days or more, proceed to store as follows:

1) Clean all accumulated dirt and grease from the Hole

Digger utilizing an appropriate solvent.


,



2) Follow the procedure as outlined in the material supplied by the engine manufacturer detailing long term storage of the engine.

3) Drain the transmission and refill with clean oil that is suitable for use when the Hole Digger will be next utilized.

4) Check all visible parts for wear, breakage or damage. Order any part required to make the necessary repair. This will avoid a needless delay when operating the Hole Digger at next use.

5) Apply a light coat of protective grease to the transmission driveshaft to prevent the formation of rust.

6) Do not store the Hole Digger connected to an auger.

Always store the Hole Digger with the operator handles level with the ground. By not storing the Hole Digger in this configuration, transmission oil may drain from the breather vent and damage the surrounding environment.

If the Hole Digger is powered by a 4

Cycle gasoline engine, this configuration will minimize the potential for crankcase oil entering the combustion chamber and creating a hydraulic lock up.
