4. Always use only the hardware provided with this unit for assembly. Never substitute parts, or mix the proper position of parts during assembly. If a part is missing, contact your local dealer for an exact replacement.

5. Assemble the unit in the sequence indicated in the assembly instructions. Make sure all hardware is properly tightened after assembly is completed and before starting the unit.

6. Make sure all required hardware has been installed. Never attempt to start or operate the unit unless you are sure that all required hardware has been used.

7. Inspect the shredder hopper and chipper cone for any debris, loose hardware, or other material that may have fallen in during unpacking and assembly. Always disconnect the spark plug wire from the spark plug, before removing any objects.

DANGER

SPARK/FIRE HAZARD

GAS ENGINES MAY REQUIRE A

SP ARK ARRESTER FOR SAFE OPERATION

If the engine on this unit is not equipped with a spark arrester and is to be used on any forest, brush, or grass-covered unimproved land, a spark arrester must be added to the muffler before using the engine on such land. The arrester must be maintained in effective working order by the operator. In the State of California, the above is required by law (Section 4442 of the California Public Resources Code.) Other states may have similar laws. Federal laws apply on federal lands. See your authorized engine service center for muffler spark arrester options.

Safety Rules & Information

OPERATING LOCATION

1. Only operate the chipper/shredder outdoors on a firm, level, earthen or grassy area where the unit will be stable and will stay in position. Never attempt to operate the unit on a slope, or on wet or slippery surfaces where you could slip and fall toward the chipper cone or hopper openings.

2. Never operate the chipper/shredder on asphalt, concrete, or other hard or paved surfaces, as material being ejected out of the discharge chute could ricochet, causing injury to you or bystanders in the immediate area.

3. Never operate the chipper/shredder where children, pets, or others who may be unaware of the potential hazards associated with chipping and shredding operations could enter the area unexpectedly and be exposed to these hazards.

4. Never operate the chipper/shredder on rocky or gravel covered surfaces, as this surface debris could enter the unit and cause extensive damage, or be ejected out of the machine with sufficient force to cause a serious injury to you or bystanders.

5. Never operate the chipper/shredder in an area where sparks from the muffler could ignite surrounding brush or flammable materials. See the following Spark/Fire Hazard Warning.

8. Never fill the fuel tank indoors! Gasoline vapors are explosive, and can easily travel unnoticed to sources of ignition, such as pilot lights or open flames on water heaters, furnaces, stoves, or dryers, sparks from electric motors and other electrical appliances, or unattended smoking materials. Contact with these or any other ignition sources will cause an explosion or fire, serious personal injury, and damage to property and equipment.

9. Never overfill the fuel tank. Fuel may run out of the tank and contact hot surfaces on the chipper/shredder motor and ignite, causing a fire and/or risk of an explosion. Fill fuel tank to 1/2” below bottom of filler neck only.

10. Use only an approved container for fuel and always handle the container with extreme care. Never smoke while fueling the chipper/shredder or transporting the fuel container.

11. Never store the fuel container or chipper/shredder indoors where there is a possibility of contact with any ignition source such as a spark, open flame, pilot light, heating element, or smoking materials.

12. Never attempt to operate a unit indoors or in an enclosed area. Engine exhaust contains Carbon Monoxide, an odorless, colorless, and tasteless gas. If inhaled, Carbon Monoxide can cause dizziness, nausea, unconsciousness, and if contact is allowed to continue, brain damage or death.

13. Operators must use extra care in handling gasoline and other fuels. These fuels are flammable and and their vapors can explode.

Controls

& Operation

SITE LOCATION

5. Never operate the chipper/shredder in an area where sparks from the muffler could ignite surrounding brush or flammable materials. See the following Spark/Fire Hazard Warning.

6. Locate the unit near the waste materials to be processed to reduce lifting and carrying.

7. Trim and stack the materials for more efficient and safe operation of the chipper/shredder unit.

8. Provide sufficient room for maneuvering around the chipper/shredder. Never set up the work area so that operators must over-reach or have to step over materials to be processed.

9. Review all operating safety instructions before proceeding.

4. Electric start: Turn the ignition key to the start position. Crank the engine until it starts.

Manual start: Pull recoil starter rope rope out and allow rope to return normally. Repeat until the engine starts.

5. Leave the throttle in the fast position for chipping and shredding.

NOTE: Because engines function differently under different conditions, the engine may need to be primed more or less than 1 time. You must determine what procedure works best for your conditions.

SHUTTING DOWN

When you’re done using the chipper/shredder, following these simple but worthwhile steps will help you shut down the unit properly so that your next use will be trouble-free.

1. When you have completed processing the materials to be chipped or shredded, shut the engine off and allow the rotor to come to a complete stop before proceeding.

2. Remove the spark plug wire from the spark plug to prevent the possibility of inadvertent starting.

3. Inspect the following areas for any remaining materials that may have built up or become caught during the final chipping and shredding operations:

• Shredder Hopper

• Chipper Cone

• Discharge Chute

• Engine Recoil Starter Area

ENGINE CONTROLS

A. Ignition Switch — has three positions: START,

RUN, and OFF. START cranks the engine for starting. RUN disengages the starter and allows the unit to run or be started with the recoil starter. OFF stops the engine.

B. Primer — assists in starting the engine by injecting

fuel directly into the venturi of the carburetor.

C. Throttle/Stop Switch — controls the engine speed

and has three positions: FAST, IDLE, and STOP. FAST runs the engine at maximum speed. This is the setting used while chipping and shredding. IDLE runs the engine at its slowest speed. Use idle to reduce stress on the engine when chipping or shredding is not being performed. STOP stops the engine.

D. Recoil Starter — is used to pull the engine over by

hand for manual starting.

GENERAL FUNCTIONS

Your Chipper/Shredder is a multi-use tool for chipping tree limbs, shredding brush and leaves, and vacuuming up leaves and small organic materials. Learning how and when to use each function will increase the value of the Chipper/Shredder in your gardening tasks.

Figure 9. Chipping of Tree Limbs

Using Your

Chipper/Shredder

WARNING

NEVER allow anyone to operate the unit or remain in the immediate area UNLESS they are wearing approved safety goggles.

Chipper

The chipper is designed to handle tree limbs and branches up to 3" (7.5 cm) in diameter. It can also process organic matter such as corn stalks and berry canes.

Tree limbs and branches should be inserted “butt end” first into the chipper cone. The cone feeds the branches into the two rotor mounted chipper knives. Because of the angle of the blades the chipper will, to an extent, feed itself. The chips of material then pass through a slot in the rotor behind the chipper knives, where discharge air flow moves them through the fan chamber and out of the discharge chute.

Shredder

The shredder is designed to shred light brush, leaves, and other soft but bulky organic waste.

As this material is loaded into the shredder hopper, it is pulled into the path of swinging triangular hammers by “J” shaped shredding hammers. The hammers cut and grind the waste into progressively smaller pieces, and air flow then forces the reduced waste through scallops and out of the discharge chute.

Rotor Vacuum Blades

In addition to the shredding hammers and chipping knives, the rotor has four integrated fan blades. When the rotor spins, a vacuum action is created, which pulls waste down into the shredder hopper and into the grinding chamber. These spinning fan blades also create a blowing force that ejects shredded or chipped material out of the discharge chute, making room for more material to be pulled in and processed.

Discharge Bag

The discharge bag allows discharged materials to be collected. Before emptying the bag, be sure to shut off the engine, allow the rotor to stop completely, and remove and secure the spark plug wire. (See

Attaching the

Discharge Bag

on page 10.)

Optional Vacuum Kit

The vacuum force created by the design of the fan blades and rotor makes it possible to equip your chipper/shredder with an optional vacuum attachment that

Figure 10. Shredding of Brush and Leaves

greatly simplifies the processing of leaves and other loose waste. The vacuum kit attaches directly to the back of the grinder. A cover is placed over the shredder hopper diverting the chipper/shredders vacuum force to the vacuum attachment.

The vacuum kit allows leaves to be raked directly into the leaf tray, where vacuum action draws the material into the shredding chamber.

For hard-to-reach places, a nozzle and handle assembly can be used to vacuum material up much like a vacuum cleaner. The strength of the vacuum can be adjusted for different situations by turning the sleeve on the nozzle assembly.

TIPS FOR BETTER CHIPPING

DO’s

1. Prune tree limbs and large branches to limit their size to the maximum diameter allowed. Pruning tree limbs and branches close to the main portion of the limb or branch will make feeding into the chipper cone easier, and will help you maintain control as the material is drawn into the chipper block.

2. Manually rotate large, hard, or dried-out tree limbs that tend to resist chipping. Rotating as well as alternately inserting and retracting large, hard, or dried-out limbs allows the chipper knives to “take smaller bites” out the of material being chipped.

3. Always maintain adequate control of the tree limbs and branches being fed into the chipper cone to prevent them from whipping around and causing injury to you or damage to the cone. Larger limbs and branches may have a tendency to kick back toward the operator, so always be alert as you feed materials into the cone.

4. Group bunches of smaller branches together for easier feeding.

PROPER TECHNIQUE FOR CHIPPING

Always maintain a stable, well-balanced stance to one side of the unit when operating the chipper/ shredder. Never stand directly in front of the chipper cone when performing chipping operations, since occasional kickbacks may occur, and result in you being struck by the tree limb or branch being kicked back.

Hold tree limbs and branches carefully to maintain control as they are being fed into the chipper cone, letting the self-feeding action of the unit pull the material in.

Never wrap your fingers around tree limbs and branches so tightly that you can’t let go quickly if the tree limb or branch is suddenly pulled into the chipper block.

Using your Chipper/Shredder

Figure 11. Correct Chipping Stance

DON’Ts

1. If the material being chipped does not easily feed into the chipper, do not force it into the chipper. If the material to be chipped is extremely hard, kicks back forcefully, or cannot be easily controlled while it is being fed into the unit, remove the material immediately and set it aside. The material may not be suitable for chipping or you may need to sharpen the chipper blades to process the material. If normal chipping operation begins to require additional feeding force to process material, the chipper knives may be in need of routine sharpening. Consult the maintenance and service section of this manual for sharpening instructions, or take your unit to an authorized service center for prompt, reliable service.

2. Never use the chipper/shredder to chip very hard, dry materials such as kiln-dried dimensional lumber (2x4’s, 1x2’s, etc.), or other building and lumber yard materials.

3. Never use the chipper/shredder to chip pressure-treated wood products such as landscape timbers, fenceposts, or other outdoor building or landscaping lumber products.

4. Avoid chipping long pieces (over 6') because the outer end can whip in a circular motion and strike you or bystanders, causing personal injuries.

5. Never place your hands in the chipper cone to feed short lengths of material. As the material is chipped, short lengths may be pushed into the chipper with another tree limb.

PROPER TECHNIQUES FOR SHREDDING

Leaves and Lightweight Organic Matter

Place material to be shredded directly into the shredder hopper. Avoid large amounts of moist material that can cause shredded matter to build up in the discharge chute and prevent proper discharge. Alternate the processing of dry and moist materials to help prevent clogging of the discharge chute. When time permits, let wet material dry out for a few days prior to shredding.

Figure 12. Feeding Leaves and Lightweight Material

Figure 13. Feeding Brush and Longer Shreddables

Figure 14. Vacuum Attachment (Optional)

A. Cover C. Nozzle and Handle B. Leaf Tray D. Vacuum Adjuster

Using the Optional Vacuum Kit

The vacuum kit attaches directly to the back of the grinder. A cover is placed over the shredder hopper diverting the chipper/shredders vacuum force to the vacuum attachment.

The vacuum kit allows leaves to be raked directly into the leaf tray, where vacuum action draws the material into the shredding chamber.

For hard-to-reach places, a nozzle and handle assembly can be used to vacuum material up much like a vacuum cleaner. The strength of the nozzle vacuum can be adjusted for different situations by turning the sleeve on the nozzle assembly.

Properly Technique For Feeding Longer Materials

When processing brush, small branches, or other long types of organic matter, feed the materials to be shredded into the shredder hopper lengthwise, butt end first, to prevent clogging of the hopper.

If brush gets tangled and clogged as it’s being fed into the hopper, never reach into the hopper to clear it while the unit is running. Shut the engine off, let the rotor come to a complete stop, and disconnect and secure the spark plug wire before attempting to clear the hopper.

Never wrap your fingers around branches so tightly that you can’t let go quickly if the branch is suddenly pulled into the shredder hopper.

TIPS FOR BETTER SHREDDING

DO’s

1. Process materials at a feeding rate that allows the rotor to keep turning at a consistently high rate of speed.

2. Alternate wet and dry material to prevent the discharge chute from becoming plugged. Dry and moist organic material including leaves, plants, flowers, fruits, and vegetables can all be shredded so long as dry and moist materials are alternated to help clear the shredder. Dry waste is more easily processed than moist waste.

3. Allow wet material to dry out for a few days prior to shredding if time permits.

If using the vacuum attachment:

4. Use the vacuum to collect light, loose, dry waste such as leaves, grass clippings, and light shavings, or sawdust.

Using your Chipper/Shredder

DON’Ts

1. Do not overload the shredder hopper by dumping large volumes of material into the hopper opening. If the engine speed slows down dramatically, you are overloading the shredder.

2. Do not feed branches and twigs larger than 1/2” in diameter, or longer than 18”, into the shredder.

3. Never use any object to force material into the shredder chamber. It could get caught in the shredding hammers and damage the unit, reducing shredder hammer effectiveness.

If using the vacuum attachment:

4. Do not overload the vacuum hose. Twigs, wet leaves, and other bulky materials will clog the hose and prevent shredding. The vacuum is engineered for small, loose waste and for cleaning around decorative landscaping and flower beds.

5. Avoid vacuum operation on areas where hard, nonorganic materials such as gravel, dirt clumps, or other hard objects could get vacuumed into the shredder chamber.

Waste Materials Guide

Using Your Chipper/Shredder

Your chipper/shredder is designed to efficiently process a wide variety of organic yard and garden waste materials. To obtain consistent performance, extend the life of your unit, and help ensure safe operation, do not attempt to process non-organic materials. If you are unsure about processing a material not covered below, contact your local authorized dealer.

If you encounter any difficulties while processing any of these recommended materials, consult the troubleshooting section of this manual for guidance and recommended corrective action.

Type Of Waste Size Limitations Method to Use Notes

Model 6/14E - 6' As the material is chipped, short lengths (2 Meters) may be pushed into the chipper with

another tree limb or batch of branches.

Never place hands in chipper cone to feed short lengths of material.

Avoid long pieces (over 6') as the outer end can whip in a circular motion and strike you or bystanders, causing personal injuries.

Never use the chipper/shredder to chip very hard, dry materials such as kilndried dimensional lumber (2x4’s, 1x2’s, etc.), or other building and lumber yard materials.

Never use the chipper/shredder to chip pressure-treated wood products such as landscape timbers, fence posts, or other outdoor building or landscaping lumber products.

NOTE: Any unusual noise or vibration, decreased performance, or engine odor, requires immediate attention.

General

The following information will help you make the necessary checks and perform the procedures required to follow the normal care recommendations made for your chipper/shredder unit.

Your local authorized dealer can make these checks and perform the required procedures for you.

CHECK FOR LOSE PARTS AND HARDWARE

Check the following areas, and tighten as required:

1. Chipper Cone & Cone Mounting

2. Shredder Hopper

3. Rotor Housing

4. Deflector Shield

OIL LEVEL

1. Oil level must be full. Check the oil level by removing and checking the engine dip-stick (Figure 15). The oil level should be up to the full mark on the dip-stick.

2. Add the recommended oil a little at a time so as not to overfill.

3. Do not overfill the engine oil! Excess oil can be detrimental to the engine.

4. After the proper oil level is reached, replace the dipstick and clean surrounding area of any spilled oil to prevent the sticking of debris that could fall into engine during the next oil check.

CHANGING OIL

Effective lubrication of the engine is critical to the life expectancy of internal engine components. Because of this, engine oil should be changed yearly when the chipper/shredder is used only occasionally, and more frequently depending on the amount of time the chipper/shredder is in use.

1. Drain engine oil by unscrewing drain plug (Figure 16) in the engine base and letting oil drain into a suitable container.

2. Dispose of the used oil by returning it to an oil recycling center or service station with a oil recycling tank.

3. After all old oil has been drained, screw drain plug in securely, and add oil as instructed in the "Oil Level” section, or see the engine manufacturer’s manual for complete details and oil specifications.

CAUTION

Do not change the engine oil if the engine has just been run. Hot oil causes burns.

CHANGING THE SPARK PLUG

An annual spark plug change is an inexpensive preventive measure that can help keep your unit running properly throughout the year.

Only replace the spark plug with the same model plug or equivalent. See the engine manual or authorized dealer for more information.

1. Disconnect and secure the spark plug wire from the spark plug.

2. Clean the area around the spark plug to remove debris that could fall into the engine when the plug is removed.

3. Using a spark plug socket and appropriate wrench, unscrew the spark plug from the engine.

4. After first setting the proper gap on the replacement spark plug (see Engine Operator’s Manual for proper gap setting for your engine), screw the new plug in and tighten. Don’t over tighten, as this could damage the cylinder head.

CLEAN ENGINE FINS & AIR INTAKE AREA

The engine that powers this chipper/shredder is aircooled and requires unobstructed air flow into and around the engine. For proper engine cooling, the cooling fins on the engine cylinder and cylinder head area must be kept clear of debris deposits and any other build-up that could prevent heat from radiating away from the engine.

To clean the air intake area, remove any debris build-up, and then blow out the area using a stream of compressed air. If a compressor is not available, use a stiff

bristle parts brush, which is available at most auto parts supply stores.

To clean the cooling fins, brush the area between the fins with a stiff bristle parts brush, and blow out any remaining debris with a stream of compressed air. If the cooling fins are caked with an oily build-up of chipper/shredder debris, using a commercially available engine cleaning aerosol may help loosen and remove the deposits.

Figure 18. Areas to clean after use

Clean Around Area

CAUTION

Compressed air can spray debris into your eyes causing permanent damage. Always wear safety glasses when using compressed air.

Never use compressed air to clean your hands or skin.

Clean Around Area

If you use such a cleaning product, you must follow all safety and use instructions to prevent damage to the engine components and personal injury to you.

NOTE: DO NOT clean the engine with a stream of water because this could contaminate the electrical and fuel systems.

AIR FILTER REPLACEMENT/SERVICE

The engine air filter element filters and removes airborne dirt, dust, and other work site debris from the air before it can enter the carburetor and damage sensitive fuel passages.

Depending on the type of air filter element installed on your chipper/shredder engine, you should periodically perform one of the following steps:

Oil Foam Element:

• Clean the element in a safe solvent (not gasoline because it is flammable) and dry with a paper towel

• Moisten the element with clean engine oil

• Ring out the excess oil with a paper towel

Paper Element

• Shake/blow out any debris caught in the element

• Inspect the element and replace if it is dirty or discolored, clean and oil the air filter (foam filter only),

Note: Consult the engine manufacturer’s manual for additional recommendations.

If you have any doubts about what type of filter element you have, consult you local authorized dealer for help.

INSPECT STARTER ROPE & HANDLE

The recoil starter rope and handle should be inspected for signs of abrasion or wear that could result in breakage. It is much easier to replace a frayed rope than a broken one.

Regular Maintenance

Figure 19. Air Filter and Recoil Starter Location

Air Filter

INSPECT BATTERY & ELECTRICAL CONNECTIONS

The battery should be inspected and cleaned every 100 hours of service or as needed. Check the electrolyte level and fill with distilled water if necessary. Fill the cells up to the bottom of the inside split ring. Clean and inspect the battery cables and terminals. Replace if corroded.

Figure 20. Battery and Cables

A. Battery B. Cables

Recoil Starter

LUBE STARTER DRIVE GEAR

The starter drive gear should be lubricated once a year or every 100 hours, or as needed. Lubricate the drive gear with a light weight oil.

Regular Maintenance

Lubrication Points

Hopper

Cone

Lubricate Both Sides

LUBRICATE WHEEL AXLES

To lubricate, squirt 3-5 drops of engine oil on each wheel axle. Wipe up any run-off and spin wheels briefly to work oil around entire axle.

INSPECT CHIPPER CONE & SHREDDER HOPPER

The chipper cone and shredder hopper are made of a highly durable polyethylene material that can withstand repeated abrasion and impact from normal chipper/shredder waste material processing.

Check these parts to make sure that they haven’t been damaged or worn excessively by constant use, and replace them if they are cracked, worn out, or no longer fit securely on the chipper/shredder unit.

Contact your local authorized dealer for replacement parts.

Cracks, worn areas, and loose attachment points can cause material to jam or clog when feeding it into the machine, and may result in kick-back or other hazard to the operator.

Contact your local dealer for replacement parts if your unit shows any evidence of these problems, and discontinue use of the unit until the appropriate repairs can be made.

Never try to make temporary repairs yourself, as the repairs could give way during chipper/shredder operation, and expose you and bystanders in the area to risk of injury.

Never attempt to install non-factory parts on your chipper/shredder unit. These parts could appear to fit, but could cause operating and safety problems that might lead to equipment damage and/or injury.

Figure 21. Starter Drive Gear Location

Lubricate Starter Gear

INSPECT HOPPER GUARDS

The hopper guards are made of a tough, flexible material that permits easy loading of the hopper, while preventing shredded pieces from being ejected out toward the operator.

The hopper guards must always be intact and properly installed to provide protection from ejected pieces.

If a hopper guard becomes damaged in use, do not operate the chipper/shredder until the hopper guard can be replaced.

Contact your local authorized dealer for replacement parts.

Regular Maintenance

STORAGE

Temporary Storage (30 Days Or Less)

Never store the chipper/ shredder indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the chipper/shredder in any structure used for human or animal habitation.

Here’s a quick checklist of things to do when storing your chipper/shredder temporarily, or between uses:

• Store the unit in a location where there’s no danger of overhead objects falling into the chipper cone or shredder hopper.

• Keep the unit in an area away from where children may come into contact with it. If there’s any chance of unauthorized use disconnect and secure the spark plug wire. Also remove the ignition key and put it in a safe place.

• Never put the unit away while the engine is still hot from running. Let the engine cool down first to prevent the chance of fire.

• Never try to lift or position the unit in the storage area by holding the fuel tank. Always let the engine and muffler cool completely before allowing yourself to contact these parts.

Regular Maintenance

• If the unit can’t be stored on a reasonably level surface, use a block of wood to block the wheels. Never store the Chipper/Shredder where it could tip over.

• Never tip the unit more than 75° from vertical, and never lay the unit down on its side, as this could cause fuel leakage and undesirable oil transfer into the cylinder head. Excessive oil in the cylinder head will prevent unit from starting properly and cause engine smoking.

• Overhead objects that fall into shredder hopper may cause damage to the unit or serious injury to user and others if not detected before unit is started.

Long Term Storage (Longer Than 30 Days)

For storage longer than 30 days, follow the steps outlined in Short Term Storage in addition to the following steps.

Your chipper/shredder can be safely stored during offseasons by following these simple storage instructions:

• Clean the external surfaces of the engine and cooling fan.

• Remove the spark plug, and squirt 1 ounce of engine oil into spark plug hole. Cover the spark plug hole and pull starter cord slowly to distribute oil evenly in cylinder head area. Reinstall spark plug.

• Drain fuel system completely following engine manufacturer’s instructions or add fuel stabilizer to prevent fuel from gumming up during an extended storage period.

• Transport unit to a suitable storage location. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing explosion and fire.

TROUBLESHOOTING

While normal care and regular maintenance will extend the life of your chipper/shredder, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly.

The troubleshooting guide below lists the most common problems, their causes and remedies.

See the repair information on the following pages for instructions on how to perform most of these minor repairs yourself. If you prefer, all of these procedures can be performed for you by your local authorized dealer.

Troubleshooting & Repair

WARNING

Never attempt to perform any of these procedures while the engine is running.

Always turn the engine off, let the rotor come to a complete stop, and disconnect the spark plug wire from the spark plug before attempting to correct any problems.

REPAIR

SHREDDING HAMMERS

The cutting edges of the shredding hammers may eventually wear out, requiring rotation of the hammers, or complete replacement if all cutting edges have been used.

Triangular hammers can be rotated five times after the first edge dulls, then flipped over once and rotated again for a total of six cutting edges. J hammers can be flipped over once (Model 5/14 only), for a total of two cutting edges. Shredding hammers need to be rotated when shredding performance becomes sluggish, or when the edges of the hammers wear down, as shown in Figure

24. To inspect and service the shredding hammers, follow

these steps:

1. Turn engine off, allow rotor to stop completely, remove the key, disconnect the battery, and disconnect and secure spark plug wire.

2. Detach the shredder hopper from the rotor housing, leaving the liner and handle in place on the hopper. See Figure 26.

3. Remove the rotor housing by unscrewing the 5/16–18 hex nuts that hold it to the fan housing. See Figure 27.

4. Using leather work gloves to protect your hands from sharp edges, carefully rotate the rotor counterclockwise until the first worn hammer is at the top position.

5. Before proceeding, note the assembly sequence of the hammer, spacer, spacer tube, and hardware. Hammers and spacers must be reassembled in the same order to ensure proper rotor balance, shredding efficiency, and safety. See Figure 28 for correct position of parts.

6. Using a 5/16” Allen wrench, remove the socket head cap screw (A, Figure 28), lockwasher (B), flat washer (C), and spacer tube (D), being careful to catch the parts as the cap screw is removed.

7. Wipe the hammer and spacer tube clean, and inspect for excessive wear.

•If the spacer tube has light grooves worn into it, the tube may be reused by flipping its position over when reinstalling it.

•If the spacer tube has deep grooves worn into it, do not reuse the part - replace it using an exact factory replacement part only.

•Rotate or flip the hammer to provide a new cutting edge, or install a new hammer if worn out or damaged.

•Reassemble the hammer and related parts and hardware, observing the correct assembly sequence as shown in Figures 28 and 29.

8. Tighten the cap screw (A, Figure 28) securely. For proper assembly, torque to 30-35 ft. lbs.

9. Rotate rotor to expose next shredding hammer, and repeat steps 6 - 8. When replacing “J” hammers, observe the correct placement of the blade toward the inside or outside of the rotor assembly.

10. If chipping knives are to be inspected or serviced, go to the following section on chipping knives. If service is to be done on shredding hammers only, proceed to next step below.

11. Reassemble the rotor housing using the 5/16-18 hex nuts removed earlier.

12. Reattach the shredder hopper, repeating the assembly sequence used when the unit was first assembled.

13. Check all hardware for tightness and correct assembly before attempting to start unit. Do not attempt to start unit if extra hardware is left over after reassembly is complete. Check all hammer assemblies before proceeding.

CHIPPING KNIVES

Chipping knives should be resharpened or replaced when tree limbs and branches require extra force to feed completely into the chipper block.

Chipping knives may be resharpened until the distance between the mounting holes and the top corner of the blade bevel is 1/16” apart. (See Figure 33 on page 29).

To inspect and service the cutting knives, follow these steps:

1. Turn engine off, allow rotor to stop completely, remove the key, disconnect the battery, and disconnect and secure spark plug wire.

2. See Figure 30. Detach the shredder hopper from the rotor housing to gain access to the chipper knife socket head cap screws. Leave the liner and handle in place on the hopper.

3. Using an allen wrench on the bolt head inside the cone, and a 7/16” wrench or socket on the nut (see Figure 31) remove the chipper cone to expose the oval chipping block and one chipping knife.

Troubleshooting & Repair

Chipping Knives.

4. Using a 1/4” hex wrench, loosen and remove the two socket head cap screws holding the chipper knife in place (access the screw heads from the rear of the unit), and remove the chipper knife.

5. See Figure 32. Remove both knives through the opening in the front of the chipper/shredder, and sharpen equally or replace both blades to ensure proper balancing and correct chipping action.

NOTE: Slow-speed water-cooled grinding is suggested to help maintain blade temper and a long-lasting sharp edge. Rapid grinding and heating of blades will soften the edges, making repeated sharpening necessary.

Chipper knives require a 30° bevel on the cutting edge (as shown in Figure 33) for efficient chipping action.

Contact your local dealer or blade sharpening service if you prefer not to sharpen the blades yourself.

6. Clean the chipper knife mounting areas before reinstalling the blades to ensure a flat mounting surface.

7. Install the new chipper knives using the two socket head cap screws, and two new lockwashers, torque to 18-20 ft. lbs. Never reinstall chipper knives

with used lockwashers, as used lockwashers may not hold the knives adequately.
