adjustable open-end wrenches that can slip off hard-
ware as it’s being fastened. Never use toothed grip-
ping pliers which may damage hardware and make
removal difficult.
Each safety alert symbol is followed by a “signal word”
that advises you of the relative intensity, or level, of the
hazard the safety alert instructions pertain to.
The following list of signal words is being provided to
help you understand the intensity levels associated with
each signal word used in this manual.
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.
Safe operation of the chipper/shredder unit requires that
all operating and safety instructions be obeyed by every-
one who uses, services, or otherwise handles the unit.
Although the instructions and warnings appearing in this

Safety Rules & Information
Setting Up Continued…
OPERATING LOCATION
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 prop-
erty and equipment.
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 sur-
faces where you could slip and fall toward the chip-
per cone or hopper openings.
2. Never operate the chipper/shredder on asphalt, con-
crete, or other hard or paved surfaces, as material
being ejected out of the discharge chute could rico-
chet, causing injury to you or bystanders in the
immediate area.
9. Never overfill the fuel tank. Fuel may run out of the
tank and contact hot surfaces on the chipper/shred-
der motor and ignite, causing a fire and/or risk of an
explosion. Fill fuel tank to 1/2” below bottom of filler
neck only.
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.
10. Use only an approved container for fuel and always
handle the container with extreme care. Never
smoke while fueling the chipper/shredder or trans-
porting the fuel container.
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.
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.
5. Never operate the chipper/shredder in an area
where sparks from the muffler could ignite surround-
ing brush or flammable materials. See the following
Spark/Fire Hazard Warning.
13. Operators must use extra care in handling gasoline
and other fuels. These fuels are flammable and and
their vapors can explode.
DANGER
SPARK/FIRE HAZARD
GAS ENGINES MAY REQUIRE A
SPARK 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 ser-
vice center for muffler spark arrester options.

Safety Rules & Information
SAFE WEARING APPAREL
OPERATING SAFETY
1. Always wear safety goggles to protect your eyes
from flying debris when operating the chipper/shred-
der. One pair of safety goggles has been provided
with the unit for your immediate use. All others in
and around the immediate area must also wear
approved safety glasses to protect their eyes from
flying debris.
1. Always obey the size limitations for tree limbs and
branches stated in the Waste Materials Guide por-
tion of this manual.
2. Never leave the machine running unattended.
Always turn off the engine, wait for the rotor to come
to a complete stop, and disconnect and secure the
spark plug wire before leaving the area. Always
move the unit to a safe storage area when not in
use.
2. Wear hearing protection when the chipper/ shredder
is to be used for prolonged periods of time, or when-
ever noise reaches an uncomfortable level.
3. Always maintain secure footing and solid balance
while starting or operating the chipper/shredder.
Never lean directly over the machine.
3. When wearing work gloves, only wear properly fitted
leather work gloves to protect your hands from cuts
and scratches caused by tree limbs and branches.
Never wear gloves with pull-ties or straps, as these
could get entangled with branches and draw your
hands into the chipper cone or shredder hopper cut-
ting areas.
4. Always stand to the side of the chipper cone when
feeding tree limbs and branches into the unit, as
tree limbs, branches, and harder woods may whip
around while being chipped.
5. Always keep hands out of the chipper cone and
shredder hopper when feeding materials. Never
wrap fingers tightly around branches as you are
feeding them into the unit, as a sudden inward surge
could pull your hands and arms into the unit.
4. Never wear loose fitting clothing, hanging jewelry,
ties, scarves, or other items that could get caught on
tree limbs, branches, or moving parts, and draw your
body parts into the cutting areas of the chipper cone
and shredder hopper.
6. Always stand clear of the discharge area to avoid
being struck by ricochets or material being ejected
from the machine.
5. Always tie up long hair and prevent it from hanging
down, where it could become tangled in branches or
get caught in rotating parts and pull you into the cut-
ting areas.
7. Never allow material to build up in the discharge
area or shredding chamber, as this may cause new
material being fed into the machine to kickback with
sufficient force to injure you or other bystanders.
6. Even if you are wearing heavy-duty leather work
gloves, never, ever place your hands in the chipper
cone or shredder hopper while the unit is running. If
you must reach in to clear a jam or free up branches,
shut the unit off, disconnect and secure the spark
plug wire at the spark plug, and carefully remove or
clear the jammed material.
8. Never allow material to build up around the engine
during chipper/shredder operation. This could result
in a fire or overheating of the engine.
9. Never attempt to reposition or move the
chipper/shredder unit while it is running. Doing so
could cause the machine to tip over, and reaching to
steady the unit could result in accidental insertion of
your hands into the chipper cone or shredder hopper
areas.
10. Never continue to operate the machine if it starts
making unusual noise or vibration. Shut the engine
off immediately, allow the rotor to stop, disconnect
the spark plug wire from the spark plug, and do the
following:
• Inspect the unit for any signs of damage or foreign
material in the chipping or shredding areas. Remove
any solid material that may be preventing the unit from
operating properly.
• Check for loose parts, and loose or missing hardware,
and repair or replace as required.

fuel could contact a hot surface and ignite, causing
fire or explosion. Turn off the engine, and allow the
engine to cool before attempting refilling.
2. If the unit must be tilted for transporting, consult the
engine manual for required preparation. Normally,
fuel and oil must be drained to prevent dangerous
fuel leakage, and unwanted transfer of the sump oil
into the cylinder head area.
13. Never attempt to perform any maintenance, repairs,
or attachment of accessories while the unit is run-
ning. Always shut the unit off, allow the rotor to
come to a complete stop, and disconnect and secure
the spark plug wire from the spark plug before begin-
ning these activities.
3. Always refill the engine with the recommended oil
before attempting to use the unit again after it has
been drained for transportation.
4. Always observe safe refueling and fuel handling
practices when refueling the unit after transportation
or storage.
14. Never remove guards, deflectors, or warning labels
from the unit. If any of these are found to be miss-
ing, take the unit out of service until the appropriate
repairs can be made. Tag the machine so others do
not mistakenly attempt to use it while awaiting parts
or repairs.
5. Always follow the engine manual instructions for
storage preparations before storing the unit for pro-
longed periods.
6. Always follow the engine manual instructions for
proper start-up procedures when returning the unit to
service.
15. Always make sure that the shredding chamber,
shredder hopper, and chipper cone are empty before
restarting the unit after it has been idle. Attempting
to start the unit with material in these areas could
cause the engine starting cord to stop suddenly,
injuring your hand and fingers, or toppling the unit
over.
SERVICE AND MAINTENANCE
1. Before performing any service or repair, shut the
engine off, wait for all moving parts to stop, then dis-
connect and secure the spark plug wire.
16. Never tamper with any engine controls to alter or
increase maximum unit running speed. An over

Using Your
Chipper/Shredder
GENERAL FUNCTIONS
WARNING
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.
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 branch-
es 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
Figure 9. Chipping of Tree Limbs
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 grind-
ing 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 materi-
al to be pulled in and processed.
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 hop-
per diverting the chipper/shredders vacuum force to the
vacuum attachment.
Discharge Bag
The discharge bag allows discharged materials to be col-
lected. 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.)
The vacuum kit allows leaves to be raked directly into the
leaf tray, where vacuum action draws the material into the
shredding chamber.
Optional Vacuum Kit
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 sit-
uations by turning the sleeve on the nozzle assembly.
The vacuum force created by the design of the fan
blades and rotor makes it possible to equip your chip-
per/shredder with an optional vacuum attachment that

Using your Chipper/Shredder
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 kick-
backs 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 con-
trol 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.
Figure 11. Correct Chipping Stance
DON’Ts
TIPS FOR BETTER CHIPPING
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 immedi-
ately and set it aside. The material may not be suit-
able for chipping or you may need to sharpen the
chipper blades to process the material. If normal
chipping operation begins to require additional feed-
ing 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 ser-
vice.
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 alternate-
ly 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 pre-
vent 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 materi-
als into the cone.
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-treat-
ed wood products such as landscape timbers, fence-
posts, or other outdoor building or landscaping lum-
ber products.
4. Group bunches of smaller branches together for easi-
er feeding.
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.

Using your Chipper/Shredder
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
Properly Technique For Feeding Longer
Materials
When processing brush, small branches, or other long
types of organic matter, feed the materials to be shred-
ded 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.
Figure 13. Feeding Brush and Longer Shreddables
Using the Optional Vacuum Kit

Using your Chipper/Shredder
DON’Ts
TIPS FOR BETTER SHREDDING
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.
DO’s
1. Process materials at a feeding rate that allows the
rotor to keep turning at a consistently high rate of
speed.
2. Do not feed branches and twigs larger than 1/2” in
diameter, or longer than 18”, into the shredder.
2. Alternate wet and dry material to prevent the dis-
charge chute from becoming plugged. Dry and
moist organic material including leaves, plants, flow-
ers, 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. Never use any object to force material into the
shredder chamber. It could get caught in the shred-
ding hammers and damage the unit, reducing shred-
der 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 deco-
rative landscaping and flower beds.
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.
5. Avoid vacuum operation on areas where hard, non-
organic materials such as gravel, dirt clumps, or
other hard objects could get vacuumed into the
shredder chamber.

Waste Materials Guide
Your chipper/shredder is designed to efficiently process
a wide variety of organic yard and garden waste materi-
als. 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 troubleshoot-
ing section of this manual for guidance and recommend-
ed corrective action.

Bulky tree limbs and branches may need
to be pruned close to the main stem to
pass through the chipper cone properly.
As the material is chipped, short lengths
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.
(2 Meters)
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 kiln-
dried dimensional lumber (2x4’s, 1x2’s,
etc.), or other building and lumber yard
materials.
Never use the chipper/shredder to chip

material, including leaves,
plants, flowers, fruits,
vegetables.
Branches and twigs
up to 1/2" diameter
and 18" long.
Shredding
Alternately chip or shred moist, green waste
with dry waste to avoid plugging of
discharge chute. If time permits, allow wet
material to dry out for a few days prior to
shredding.
Light, loose, dry waste, such
as leaves, grass clippings,
and light shavings, or
sawdust.
Small materials that
will not obstruct the
vacuum hose as it’s
being vacuumed.
Vacuum/
Shredding
(Optional)
The vacuum is engineered for small, loose
waste and for cleaning around decorative
landscaping and flower beds. Twigs, moist
leaves, and other bulky materials will clog
the hose and prevent shredding.
Dry waste is more easily processed than
moist waste. Process at a feeding rate that
allows the engine to keep turning
at a consistently high rate
of speed.
Avoid vacuum operation on areas where
hard, non-organic materials such as gravel,
dirt clumps, or other hard objects could
get vacuumed into the shredder chamber.

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.
Figure 15. Oil Dip Stick Location
3. Do not overfill the engine oil! Excess oil can be detri-
mental to the engine.
4. After the proper oil level is reached, replace the dip-
stick and clean surrounding area of any spilled oil to
prevent the sticking of debris that could fall into
engine during the next oil check.
*2556
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 chip-
per/shredder is used only occasionally, and more fre-
quently 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 recy-
cling center or service station with a oil recycling
tank.
Figure 16. Engine Oil Drain Plug
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.

Regular Maintenance
CHANGING THE SPARK PLUG
An annual spark plug change is an inexpensive preven-
tive measure that can help keep your unit running prop-
erly throughout the year.
Electrodes
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.
Figure 17. Spark Plug Gap Setting
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 dam-
age the cylinder head.
CLEAN ENGINE FINS

Area
The engine that powers this chipper/shredder is air-
cooled and requires unobstructed air flow into and
around the engine. For proper engine cooling, the cool-
ing 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 com-
pressed air. If a compressor is not available, use a stiff

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

Regular Maintenance
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 pas-
sages.
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:

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 discon-
tinue use of the unit until the appropriate repairs can be
made.
Lubricate Both Sides
Figure 22. Cone, Hopper Location and Wheel Axle

Never try to make temporary repairs yourself, as the
repairs could give way during chipper/shredder opera-
tion, and expose you and bystanders in the area to risk
of injury.
Never attempt to install non-factory parts on your chip-
per/shredder unit. These parts could appear to fit, but
could cause operating and safety problems that might
lead to equipment damage and/or injury.

Regular Maintenance
INSPECT HOPPER GUARDS
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 oper-
ator.
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 oper-
ate the chipper/shredder until the hopper guard can be
replaced.
Contact your local authorized dealer for replacement
parts.

Regular Maintenance
• If the unit can’t be stored on a reasonably level sur-
face, use a block of wood to block the wheels.
Never store the Chipper/Shredder where it could tip
over.
CHECK SAFETY LABELS
Safety warning decals are placed at strategic locations
on the chipper/shredder as a constant reminder to the
operator of the most important safety precautions. All
Warning, Danger, Caution, and instructional messages
on your chipper.shredder should be carefully read and
obeyed.
• 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.
If any of these decals are lost or damaged, replace them
at once. They can be purchased from your dealer. A list
of these decals is located at the end of the “Safety Rules
and Information” section of this manual.
• 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.
STORAGE
Long Term Storage (Longer Than 30 Days)
For storage longer than 30 days, follow the steps out-
lined in Short Term Storage in addition to the following
steps.
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 ani-
mal habitation.
Your chipper/shredder can be safely stored during off-
seasons by following these simple storage instructions:
• Clean the external surfaces of the engine and cool-
ing 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.
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.
• Drain fuel system completely following engine manu-
facturer’s instructions or add fuel stabilizer to prevent
fuel from gumming up during an extended storage
period.
• 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.
• 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 dis-
tant sources of ignition and ignite, causing explosion
and fire.
• Never put the unit away while the engine is still hot
from running. Let the engine cool down first to pre-
vent 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.

SHREDDING HAMMERS
The cutting edges of the shredding hammers may even-
tually 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:
Figure 26. Removing Shredder Hopper
1. Turn engine off, allow rotor to stop completely,
remove the key, disconnect the battery, and discon-
nect and secure spark plug wire.
2. Detach the shredder hopper from the rotor housing,

4. Using leather work gloves to protect your hands from
sharp edges, carefully rotate the rotor counterclock-
wise until the first worn hammer is at the top posi-
tion.
The J Hammer (G) on
the opposite side of the
rotor faces outward for
balanced rotation.
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, shred-
ding efficiency, and safety. See Figure 28 for correct
position of parts.

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 discon-
nect 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.
Figure 30. Removing Shredder 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
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.

CAUTION
The chipper blades have sharp edges. Wear
leather work gloves and remove the blades care-
fully.
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.
Figure 32. Removing Chipper Knife Through Front
Opening
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.

Min.
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 rein-
stalling 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.

8. Reattach the shredder hopper and chipper cone
using the hardware removed during disassembly.
Replace any hardware that appears to be damaged
or worn excessively.
9. Check all hardware for tightness and correct assem-
bly before attempting to start your unit. Do not
attempt to start the unit if extra hardware is left over
after reassembly is complete. Check for proper chip-
per knife assembly before proceeding.
10. Test the unit before attempting to use it to perform
chipping. Start the unit, and check for unusual noise
or vibration.

• Shut the unit off immediately if either situation occurs
and reinspect chipping knives to confirm correct
positioning and assembly.
• If assembly is correct, the blades may not have been
sharpened evenly--causing an imbalance. Remove
the blades and sharpen the evenly.
• Recheck the unit. If problem persists, contact your
local dealer for assistance.
