OPERATION

 Never place your hands, feet, or any part of your body in the shredder hopper, chipper chute, discharge

opening, or near or under any moving part while the shredder/chipper is running. Keep clear of the discharge
opening at all times. If it becomes necessary to push material into the shredder hopper or chipper chute, use a
small diameter stick, NOT YOUR HANDS.

 Keep your face and body back from the shredder hopper and chipper chute to avoid accidental bounce back of

any material.

 The machine should only be operated on a level surface. Never operate your unit on a slippery, wet, muddy, or

icy surface.

 Exercise caution to avoid slipping or falling.
 Stay alert for hidden hazards or traffic. Do not carry passengers.
 If the cutting mechanism strikes a foreign object or if your machine should start making an unusual noise or

vibration, immediately stop the engine, remove the spark plug wire(s) and wait for all moving parts to come to a
complete stop. After the machine has come to a complete stop proceed as follows:

 Inspect for any damage.
 Repair or replace any damaged parts before restarting and operating the machine.

 If the machine should start to vibrate abnormally, immediately stop the engine, remove the spark plug wire(s)

and wait for all moving parts to come to a complete stop and inspect for the cause. Vibration is generally a
warning sign of trouble.

 Stop the engine when leaving the operating position, and when making any repairs, adjustments and

inspections.

 Take all possible precautions as recommended by the manufacturer when leaving the machine unattended.

Stop the engine and remove the key if so equipped.

 Before cleaning, repairing, or inspecting, shut off the engine and make certain the flywheel and all moving parts

have come to a complete stop. Disconnect the spark plug wire and keep the wire away from spark plug to
prevent accidental starting. Do not use flammable solutions to clean air filter.

 Never run this machine in an enclosed area as the exhaust from the engine contains carbon monoxide, which

is an odorless, tasteless, and deadly poisonous gas.

 Keep all guards and safety devices in place and operating properly. Do not operate the machine if all safety

guards are not in place.

 Do not use the unit with the shredder hopper or chipper hopper removed.
 The muffler and engine become hot and can cause a severe burn. Do not touch.

objects are not included. Personal injury or damage to the machine could result.

7

 Keep area of discharge clear of people, animals, buildings, glass or anything else that will obstruct clear

discharge, cause injury or damage. Wind can also change discharge direction, so be aware.

 Do not allow an accumulation of processed material to build up in the discharge area as this will prevent proper

discharge and can result in kickback from the shredder hopper or chipper chute.

 Do not allow any part of the engine, especially around the cooling fans and muffler, to become clogged with

processed material, leaves, oil, grease or any other combustible material.

 Do not operate engine if air cleaner or cover over carburetor air-intake is removed, except for adjustment.

Removal of such parts could create a fire hazard.

TOWING – HIGHWAY TOWABLE MODEL

 Obey all state and local regulations when towing on public roads and highways.
 Before towing, be certain the shredder chipper is correctly and securely attached to the towing vehicle and the

safety chains are in place. Leave slack in the chains to allow for turning.

 Do not allow anyone to sit or ride on the shredder/chipper. This can cause serious injury.
 Stay alert for hidden hazards or traffic. Do not carry passengers.
 Never carry any cargo or wood on your shredder/chipper. It may fall off and endanger following vehicles.
 Allow for added length when turning, parking, and crossing intersections and in all driving situations.
 Be care when backing up, you. You can easily jackknife your shredder/chipper.
 Adjust towing speed for terrain and conditions. Do not exceed 45 MPH when towing.
 Because there is no suspension on the shredder/chipper, it will tend to bounce more on rough roads. Be extra

cautious when towing over bumpy or rough terrain including railroad crossings.

MAINTENANCE AND STORAGE

 Keep machine, attachments and accessories in safe working condition.
 Check engine mounting bolts and other hardware at frequent intervals for proper tightness. Never operate your

shredder/chipper in poor mechanical condition or when in need of repair. Be sure all safety guards and shields
are in proper position. These safety devices are for your protection.

 Never store machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot

water and space heaters, clothes dryers and the like. Allow the engine to cool before storing in any enclosure.

 Always refer to the operator’s manual for important details if the machine is to be stored for an extended period.
 If the fuel tank is to be drained, do this outdoors.
 Follow the manufacturer’s recommendations for safe loading, unloading and storage of machine.
 If it is necessary for any reason to unclog the feed intake or discharge openings or to inspect or repair the

machine where a moving part can come in contact with your body or clothing, shut the machine off, allow all
moving parts to come to a complete stop and disconnect spark plug wire(s) before attempting to unclog, inspect
or repair.

 Check the knife mounting screws at frequent intervals for proper tightness. Also visually inspect the knife for

wear or damage. Replace the knife with parts that meet original equipment specifications.

 Knives should be checked for sharpness and the bolts attaching them to the flywheel for tightness every 8-10

hours of operation.

 Check the gap between the knife and wear plate every time you sharpen or replace the knife, or every 8-10

hours of operation.

 Never tamper with safety devices. Check their proper operation regularly.
 Inspect the belt each time you use the unit. Look for damage, worn areas or tears. Do not use the unit if this

condition exists.

 Do not tamper with the engine’s governor setting. The governor controls the maximum safe operation speed

and protects the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to
the other moving parts of the machine. See your authorized dealer for engine governor adjustment

SECTION III - LUBRICATION & ENGINE START UP

FOR INFORMATION ABOUT:

 OIL
 FUEL
 STARTING
 STOPPING
 RECOMMENDED MAINTENANCE
 SERVICE
 STORAGE
 ENGINE WARRANTY INFORMATION

REFER TO THE ENGINE OWNER’S MANUAL.

THE ENGINE ON YOUR CHIPPER SHREDDER HAS BEEN SHIPPED DRY.

BE SURE TO SERVICE THE ENGINE ACCORDING TO THE ENGINE

OWNER’S MANUAL PRIOR TO STARTING.

FAILURE TO DO SO CAN RESULT IN DAMAGE NOT WARRANTIED BY THE

ENGINE MANUFACTUROR.

WARNING: Do not fill closer than ½” from the top of the fuel tank to prevent spills and to allow for

fuel expansion. If gasoline is accidentally spilled, move the machine away from the area of the spill.

Avoid creating any source of ignition until gasoline vapors have disappeared.

CAUTION: Experience indicates that alcohol blended fuels (gasohol, ethanol, methanol) can attract moisture which
leads to separation and formation of acids during storage. Acidic gas can damage the fuel system or an entire
engine while in storage. To avoid engine problems, the fuel system should be empty before storage for periods
over 30 days. For more information, refer to the engine owner’s manual. Use fresh fuel each season. Never use
engine or carburetor cleaner products in the fuel tank or permanent damage may result.

ALWAYS CHECK OIL LEVEL PRIOR TO

STARTING THE CHIPPER SHREDDER.

16

SECTION IV – SHREDDING & CHIPPING

THIS SHREDDER/CHIPPER WAS DESIGNED FOR SHREDDING LEAFY GARDEN OR

ORGANIC MATERIAL AND CHIPPING LIMBS OR BRANCHES. NEVER USE THIS

MACHINE FOR ANY OTHER PURPOSE AS IT COULD CAUSE SERIOUS INJURY.

CONTACT WITH INTERNAL ROTATING HAMMERS WILL CAUSE SERIOUS PERSONAL

INJURY. DO NOT PUT HANDS, FACE, FEET OR CLOTHING INTO THE SHREDDER

HOPPER, CHIPPER CHUTE, DISCHARGE OPENING OR NEAR THE DISCHARGE AREA AT

ANY TIME.

MAINTENANCE AND SERVICE SHOULD ONLY BE PERFORMED AFTER THE ENGINE IS

OFF AND ALL MOVING PARTS HAVE COME TO A COMPLETE STOP. USE ONLY A

WOODEN STICK TO CLEAR JAMMED MATERIAL AFTER ALL MOVING PARTS HAVE

STOPPED COMPLETELY.

SAFETY FIRST

 Always wear protective gloves and safety glasses during operation of the

shredder/chipper.

 Never allow your hands or any part of your body or clothing inside the feed hoppers or

discharge area of the shredder/chipper.

 Keep all protective guards and warning labels on the machine and in good working

condition.

 Always stand clear of the discharge area when the shredder/chipper is running.
 Keep your face and body back from the feed hoppers to avoid being struck by any

material that may bounce back.

 Keep proper balance and footing while operating the shredder/chipper.
 If it becomes necessary to push material into the feed hoppers, only use a wood stick,

never your hands or anything steel.

 Never assume you know where the chipper knife is. You do not know where it is.
 Keep area of discharge clear of people, animals, buildings, glass or anything else that will

obstruct clear discharge, cause injury or damage. Wind can also change discharge
direction, so be aware.

 Always keep hands out of the feed hoppers.
 Never operate the shredder/chipper without the hoppers in place.
 Do not transport the shredder/chipper with the engine running.

PROCESSING MATERIAL

 Your shredder/chipper can process dry or green material.
 Green material will process quicker and easier than dry material.
 Soft wood processes easier the hard wood.
 Your operator experience will teach you how different materials shred and chip.
 Your operator experience will teach you how fast you can process different materials.
 Most materials process well with the standard screen provided with the unit.

17

 When chipping branches, sometimes a tail will be left at the end of a branch. To avoid

this, rotate the branch as it is fed into the chute.

 Rotating the branch as you feed it into the machine will improve chipping performance.
 An optional screen is available for greater reduction of the material being processed

through the shredder hopper.

USING THE SHREDDER HOPPER

 The shredder hopper is located on the top of the unit and is the opening into which all materials to be shredded

should be fed. Most organic materials can be shredded. A flex guard, or blowback shield is secured to the
hopper. Material must be pushed past this flap using a wooden stick in order to enter the main shredding
chamber where revolving steel hammers do the shredding. The blowback shield is an important feature. It

prevents kickback of materials! Do not use your machine unless the blowback shield is securely
fastened in place.

 Due to the wide variety of materials that can be shredded, and their very different physical characteristics, only

feed limited quantities of any material into the hopper at first. The amount and length of material can be
increased if you find that the material is being processed without any difficulty. Your judgment and operator
experience are very important. Be sure not to overload the machine by feeding too much material into the
hopper at one time. If you hear the RPM’s of the engine decreasing, stop feeding material into the machine at
once. Do not resume feeding the machine until it has returned to full speed.

 The maximum diameter of material that can be shredded is 1”. Any larger material should be fed through the

chipper-hopper. Material larger than 1” can cause serious damage to any of the internal parts of the shredding
chamber. The unit should be inspected after every use for bent hammers, missing spacers, damage to the
screen or any other obvious problems. If damage occurs, the rotor assembly can become unbalanced causing
excessive vibration. If used in this state, damage can occur. Do not use the machine if vibration is present.
Vibration is generally a warning sign of trouble.

 Several small branches can be fed into the shredder-hopper at once providing their combined diameter is less

than 1”. Branches longer than three feet should be cut to make them more manageable. Green materials
should be allowed to dry, or processed in small batches with dry materials to avoid winding around the rotor
assembly.

 Wet materials will clog the machine easily. For best results, allow wet materials to dry for 7 to 10 days before

processing. If clogging occurs, you can remove the screen and process material without, but the reduction will
not be as great. Slowing your rate of feeding material into the machine will also reduce the chance of clogging.

MATERIALS BEST SUITED FOR SHREDDING

 Leaves
 Roots
 Grass clippings
 Straw
 Hay
 Small branches

 Flowers
 Soil
 Garden debris
 Hedge clippings
 Kitchen Waste
 Manure

 Corn Stalks
 Palm frond tops
 Potato vines
 Tomato vines
 Paper

NOTE - The hammers within the shredding chamber can tug suddenly at material being

fed into the shredder-hopper. Do not hold on tightly to branches and vines, and don’t

feed material straight down into the hopper with your arm pointing downward toward

the opening. Instead, keep your arms parallel to the ground and several inches above

the top edge of the hopper.

18

USING THE CHIPPER HOPPER

 This chipper-hopper is mounted on the side of the machine and is designed to chip the larger, heavier materials that

the shredder-hopper isn’t designed to handle. Branches fed into the chute are turned into “chips” by the revolving
chipper knife mounted on a flywheel. The chipper-hopper can chip branches and vines ranging in size from 1” to 4”
in diameter. Cut your materials into manageable lengths before feeding them into the chipper.
Note: The chipper hopper must be securely bolted to the side of your equipment before using the machine!

 Do not force material into the chipper. If the machine does not chip well, the chipper knives need replaced or

sharpened or the gap between the knife and the wear plate needs adjusting.

 Extremely hard knots will not process very well. Short stubs that have not self-fed through the chipper can be

pushed through with the next branch to be chipped. DO NOT THROW REMAINING STUBS OR UNCHIPPABLE
KNOTS INTO THE SHREDDER-HOPPER. DAMAGE WILL RESULT.

 Cut chipping material into manageable lengths of no more than five or six feet long before chipping them.
 If branches are larger than 1” in diameter, feed only one branch at a time through the chipper hopper.
 Branches smaller than 1” in diameter can be bundled together and fed through the chipper hopper at one time.
 Overloading the shredder/chipper will cause the rotor speed to decrease. If you hear the RPM’s decreasing, stop

feeding material into the machine until the machine has returned to full speed.

MATERIALS BEST SUITED FOR CHIPPING.

 Branches, vines or stalks from 1” to 4” in diameter.

USE COMMON SENSE WHEN USING YOUR SHREDDER/CHIPPER.

 LEARN TO RECOGNIZE THE CHANGE IN THE SOUND OF YOUR MACHINE WHEN IT IS

OVERLOADED.

 BECOME FAMILIAR WITH SUCCESSFUL OPERATING CONDITIONS AND AVOID THOSE THAT

CAN OVERLOAD AND DAMAGE THE MACHINE.

 IF THE MACHINE BECOMES JAMMED BY OVERLOADING OR ANY OTHER CAUSE, STOP THE MACHINE

IMMEDIATELY.

 IF YOU JAM THE MACHINE AND DO NOT STOP THE ENGINE, IT CAN DAMAGE THE MACHINE. THIS

DAMAGE CAN BE COSTLY AND IT MAY NOT BE COVERED UNDER WARRANTY. FOR THIS REASON, IT
IS IMPORTANT THAT YOU IMMEDIATELY STOP THE ENGINE IF THE MACHINE BECOMES JAMMED.

 ONLY YOUR OPERATOR EXPERIENCE WILL TELL YOU HOW FAST TO FEED MATERIAL TO BE

PROCESSED.

 CHECK TO SEE THAT THE FLYWHEEL WILL TURN FREELY BEFORE YOU START THE

SHREDDER/CHIPPER.

 VISUALLY CHECK CHIPPER KNIFE FOR DAMAGE EACH TIME YOU USE YOUR SHREDDER/CHIPPER.

 CHECK KNIFE CONDITION, WEAR PLATE CONDITION, GAP SETTING AND THE NUTS AND BOLTS THAT

HOLD THE KNIFE IN PLACE FOR TIGHTNESS EVERY 8-10 HOURS OF OPERATION.

 DO NOT ALLOW PROCESSED MATERIAL TO BUILD UP WITHIN 3” OF DISCHARGE CHUTE OPENING.

TURN THE MACHINE BEFORE MOVING THE SHREDDER/CHIPPER OR PILE AS NEEDED. FAILURE TO DO
THIS COULD RESULT IN UNNECESSARY JAMMING OF THE MACHINE.

 TO MOVE PILE OF PROCESSED MATERIAL, TURN THE MACHINE OFF AND USE A SPADE, RAKE, OR

LONG HANDLE TOOL. NEVER USE YOUR HANDS OR FEET!

19

SECTION V – MAINTENANCE & STORAGE

IMPORTANT: The knife should be checked for sharpness and the bolts attaching them to the flywheel for
tightness every 8-10 hours of operation.

IMPORTANT: Every time you perform maintenance or any kind of service or check on the knife, be sure to check
the gap between the knife and wear plate for proper setting.

NOTE: A knife gauge has been provided with your machine. It is 1/16th” thick and should be used to set the
correct gap between the knife and wear plate.

If the cutting mechanism strikes any foreign object or if your machine should start making an unusual noise or is
vibrating, stop the engine, disconnect the spark plug wire(s) from the spark plug(s). Allow the engine to cool before
you:

a. Inspect and examine for damage.
b. Check for loose nuts, bolts or parts.

1. When not in use, your shredder/chipper should be stored out of the reach of children. Be sure that there are no
gasoline fumes in the storage area. For long periods of storage (over the winter), refer to the engine owner’s manual.

2. After every 8 hours of operation, lubricate the chipper side bearing. To do this, wipe all dirt, etc., from the grease
fittings with a clean cloth, then apply no more than 3 shots of quality general-purpose grease with a hand-pumped
grease gun. Over lubrication can also damage bearings. Also, check the bearing collar set screws regularly to be
sure they are tight. If they are loose, reset them with Loctite 243, obtainable at any hardware store.

3. You will find information included referring to operation and maintenance of the engine. Look it over carefully. BE
CERTAIN TO ADD OIL BEFORE STARTING IT.

4. When the steel chipping knife needs replacing or sharpening, refer to the section on removal, sharpening and re­installation.

5. Care must be exercised when sharpening the knife to maintain the correct bevel and a straight edge. Refer to
sharpening directions. When you install a knife, the clearance between the knife and wear plate must be checked and
set. This clearance or gap should be set to 1/16” (see figure 1).

6. To adjust this clearance, loosen the three ¼” nuts and bolts
holding the wear plate in place. The wear plate can be slid up
or down (in or out) to achieve the correct gap setting.

7. Take the knife gauge and slide between the knife and wear
plate. If the gap is set correctly, the knife gauge will lightly
touch both the knife and wear plate. If the gap is too small, you
will not be able to get the gauge between the knife and wear
plate. If the gap is too large, there will be excess room between
the knife gauge, knife and wear plate. Tighten the nuts and
bolts when the wear plate is in the correct position. Be certain
the flywheel rotates without hitting anything before starting the
chipper.

8. If the gap between the wear plate and the knife is not set
correctly, you will have excessive vibration when chipping and
the blade will seem to be dull. This should be checked every 8­10 hours of operation.

9. If at any time it becomes necessary to disassemble the chipper
for repairs, the chipper disk must be re-installed in exactly the
same position on the rotor shaft.

c. Repair or replace any damaged parts before restarting and operating the machine.

NOTE: Proper gap setting is critical to the proper operation of your machine.

REMOVAL, SHARPENING AND RE-INSTALLATION OF CHIPPER KNIFE

HOW TO REMOVE THE KNIFE

 Stop the engine.
 Remove spark plug wire(s) and keep away from spark plug(s).
 Disconnect battery at negative terminal.
 Open the access cover on the chipper basic machine.
 Rotate the chipper disk until the three countersunk screws attaching the knife to the flywheel are visible through

the access door.

 Clean out the heads of the allen screws with an awl or sharp tool.
 Insert a 3/16” allen wrench into the heads of the screws.
 While applying pressure with the allen wrench, apply heat from a propane torch to the screws to break loose the

Loctite on the screws.

 Remove the heat once the screws have loosened.
 Remove all three allen screws in this manner.

KNIFE SHARPENING

 You should never attempt to sharpen the chipper knife freehand.
 It is extremely important that the 45-degree angle be maintained consistently for proper performance.
 The chipper knife should be taken to a machine shop for proper sharpening.
 Excessive heat generated during the sharpening process will damage knives and weaken the metal. Be sure the

knife is not overheated.

KNIFE INFORMATION

 The chipper knife should be checked routinely for sharpness.
 Using a dull knife will decrease performance and cause excessive vibration that will cause damage to the

shredder/chipper.

 How many times a knife can be sharpened is determined by how much material needs to be taken off to sharpen

or to compensate for dents or gouges.

 A new chipper knife has 5/16” measurement between the short side bevel edge and the knife mounting holes.

See figure 2.

Figure 2

21

 The knife should never be sharpened to the extent that more than 3/32” is taken off this measurement.
 Once this measurement is below 7/32” (see figure 3) the knife should be replaced.
 If you are unable to remove dents or gouges with these guidelines, replace the knife.

Figure 3

KNIFE INSTALLATION

 Clean chipper disk where knife is going to be attached.
 Visually inspect the chipper disk slot and knife mounting area and be sure they are clean and that the knife will be

able to mount flush against the chipper disk.

 Visually inspect and clean the knife.
 Apply Loctite 243 to the socket head cap screws that hold the knife in place.
 Hand tighten the knife to the chipper disk. If you are installing a new knife, use the new hardware that comes with

the knife when attaching it to the chipper disk.

 Tighten the center bolt.
 Tighten the outer bolt.
 Tighten the inner bolt.
 Double-check all three for tightness one more time.

WEAR PLATE

 The wear plate should have a square edge and be free of dents or gouges.
 The wear plate can be sharpened by hand, but as with the knife, do not overheat during the sharpening process.

This will change the characteristics of the steel and it should be replaced.

 Check the gap between the knife and wear plate every time any adjustments are done to either piece, or every 8-

10 hours of operation.

22

AFTER ANY BLADE OR WEAR PLATE MAINTENANCE OR ADJUSTMENT, ROTATE THE

CHIPPER DISK BY HAND. WATCH AND LISTEN CAREFULLY FOR ANY UNUSUAL NOISES,

CLICKING OR VIBRATION. IF ANY OF THESE ARE DETECTED, INSPECT THE MACHINE FOR

DAMAGE. REPAIR OR REPLACE ANY DAMAGED PARTS AND CHECK FOR ANY LOOSE

PARTS AND RETIGHTEN.

KNIVES MUST BE CHECKED AND MAINTAINED!

THE KNIFE MUST BE SHARP!

BE SURE TO REINSTALL THE KNIFE CORRECTLY AND DOUBLE CHECK FOR

TIGHTNESS!

HAMMERS

When the hard steel hammers of the rotor assembly become dull or round on the cutting edge, they
may be rotated or reversed. These hammers have four cutting edges that may be used before
replacement is necessary. To reverse the hammers proceed as follows.

 Remove belt guard.
 Remove round cover plate from behind belt guard.
 Remove the top plate.
 Remove shredder hopper.
 Turn rotor assembly until hammer rod is facing up.
 Turn hammer rod until end of pin is facing up.
 Drive the roll pin from the hammer rod with a punch.
 Remove hammer rod through access hole on side of machine.
 Reverse hammers and reinstall with spacers on hammer rod.
 Replace old roll pin with new roll pin if necessary.

NOTE: Be sure the hammers and spacers are reinstalled in exactly the order in which they were removed. Refer
to the rotor assembly drawing for the correct order.

23

INSTRUCTIONS FOR ADJUSTING OR REPLACING BELT

BELT ADJUSTMENT

The belt on your chipper should deflect 3/8” under three pounds of pressure as shown in figure 1
below. If it doesn’t, adjust per the following directions.

Figure 1

 Remove belt guard.
 Loosen engine bolts.
 Tighten or loosen the nut on the belt tensioner until you have the correct tension as shown in

figure 1.

 Retighten engine bolts.
 Check alignment of the clutch with the drive pulley by placing a straightedge across both faces

as shown in figure 2. If adjustment is necessary, correct alignment by moving rotor pulley in or
out on the rotor shaft. Do not make adjustment by moving the clutch on the engine shaft.

 Replace belt guard.

Figure 2

BELT REPLACEMENT

 To replace the belt, follow the above belt adjustment directions.
 After you have loosened the engine bolts, remove the old belt and replace it with a new one.
 Set belt tension and alignment per above directions.

NOTE: Check and re-tighten belts after initial break-in period, one hour of use.

CENTRIFUGAL CLUTCH TECH TIPS

CLUTCH PART NO. 030-0202

THE SHOES AND SPRINGS ON THE CLUTCH ARE NORMAL WEAR ITEMS. IF YOU NOTICE

DECREASED PERFORMANCE OF THE CLUTCH THEY SHOULD BE CHECKED AND

REPLACED IF NECESSARY.

The clutch on your machine is designed for rugged, dependable service, however, it is
important to understand the limitations of a clutch. A clutch is designed to provide load free
starting of the engine, and slippage under excessive overloading of the driven application.
These features help protect the engine from damages such as broken crankshafts and
starters.

The clutch obtains its power from engine RPM’s. The lower the engagement speed, and the
higher the maintained engine speed, the more torque the clutch can transfer to the driven unit.

Do not operate at less than full RPM’s.

 At engine start-up, the engine of your chipper operates under no load until approximately

1000-1200 RPM’S at which speed the centrifugal clutch engages and begins driving the rotor.

 Proper rotor speed is 2400 RPM +/- 200 RPM.
 Do not tamper with the engine’s governor setting. The governor controls the maximum safe

operation speed and protects the engine. Over-speeding the engine is dangerous and will
cause damage to the engine and to the other moving parts of the machine. See your
authorized dealer for engine governor adjustments.

 Become familiar with successful operating conditions and avoid those that can

overload and damage the machine.

 Do not overload or attempt to chip material beyond manufacturers recommendation. Personal

injury or damage to the machine could result.

 Learn to recognize the sound of the machine when it is overloaded.
 If the machine becomes jammed by overloading or any other cause, stop the machine

immediately.

 If you jam the machine and do not stop the engine, it can:

 Burn the belt.
 Ruin the clutch.

 Only your operator experience will tell you how fast you can successfully feed limbs into the

machine.

 Clutch damage can be costly and it may not be covered under warranty. For this

reason, it is important that you immediately shut off the machine if it becomes jammed.

25

CLUTCH MAINTENANCE

The centrifugal clutch on this machine is permanently lubricated and does not require oil or
grease. More lubricant can be added to the bushing. Any standard motor oil is recommended.
