one using the chipper/shredder unit must also always fol-
low safe work practices while operating, servicing, or
handling the chipper/shredder unit under any conditions
not specifically covered in this manual.
SETTING UP
All Models
1. Although most assembly has been done at the facto-
ry, your chipper/shredder unit requires minor assem-
bly and the addition of engine oil before it can be
used. Never attempt to start or operate the unit
unless the chipper cone and shredder. hopper have
been properly installed and engine oil has been
added.
2. Perform the required assembly in an area where the
-chipper/shredder can be handled comfortably. Never
attempt to assemble the unit uniess the engine/base
assembly can be held or securely positioned for
assembly needs.
3. Use proper hand tools for assembling the
chipper/shredder. Never use tools such as
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.
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 (gas engine)
or power cord (electric) before removing any objects.
Model 2/10
1. Always use an extension cord approved for outdoor
use by the cord manufacturer. Never use indoor type
Ae ee
extension cords as these are suitable for use only
with lamps or other small appliances.
2. Always use a cord approved for handling the voltage
and amperage as stated on your chipper/shredder
motor identification plate.
3. An Underwriters Laboratories listed ground fault cir-
cuit interrupter is highly recommended, and may be
required for outdoor power receptacles by your local
electrical code. Check with your local code authority
for more information on this important safety device.
4, Always use a power receptacle and electrical circuit
with adequate capacity to handle the requirements of
your chipper/shredder model. Never install a larger
fuse or circuit breaker to compensate for greater cur-
rent demand unless you have also upgraded the cir-
cuit wiring accordingly. |
5. Frequent overloads and circuit interruptions can over-
heat house wiring and cause a fire. If this occurs, dis-
continue chipper/shredder use until appropriate cir-
cuit improvements can be made.
Models 3/10 & 5/10
1. 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 оп
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.
2. 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. 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.
4. 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.
5. Never attempt to operate a unit indoors or in an
enclosed area. Engine exhaust contains Carbon
Monoxide, an odorless, colorless, and tasteless gas.
lf inhaled, Carbon Monoxide can cause dizziness,
nausea, unconsciousness, and brain damage or
death if contact is allowed to continue.
safety Rules
OPERATING LOCATION

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, 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 imme-
diate 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 grav-
el 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.
Model 2/10
Never operate the unit in damp or wet locations. A shock
hazard to the operator and others who might touch the
unit exists under these conditions, and severe shock,
personal injury from electrical burns, or electrocution
could result.
Models 3/10 & 5/10
Never operate the chipper/shredder in an area where
sparks from the muffler could ignite surrounding brush or
flammable materials. See the following Fire Hazard
warning.
A 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.

DESCRIPTION
General
Your new chipper/shredder is designed to permit years
of trouble-free operation while handling a wide range of
chipping and shredding needs.
To help you get the most out of your investment, as well
as to help you understand how the unit works, this section
explains the basic operation of the chipper/ shredder.
Chipper Operation
Models 2/10 & 3/10 are designed to handle tree limbs
and branches up to 2" in diameter while the Model 5/10
can handle limbs and branches up to 3” in diameter. The
powerful motor and durable chipping knives also permit
the processing of tough organic matter such as corn
stalks and berry canes.
Tree limbs and branches are inserted “butt end” first into
the chipper cone, and are fed into the chipper block,
where two chipper knives mounted on a heavy duty rotor
rotate at 3600 rpm. The sharp cutting edges and angle
of the blades actually pulls the tree limbs and branches
into the chipper block, cutting the wood into small chips,
and promoting rapid material processing.
The chips of material then pass through a slot in the rotor
behind the chipper knives, where they are shredded until
the material is reduced in size and passes through the
discharge screen and out of the discharge chute.
Shredder Operation
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 patented swinging triangular and “J” shaped
shredding hammers.
The hammers cut and grind the waste into progressively
smaller pieces, and air flow then conveys the reduced
waste out of the discharge chute.
Because of this unique swinging hammer design and tri-
angular shape, the chipper/shredder has 300% more
shredding power than conventional rectangular shred-
ding hammers used by others.
The Vacuum Action
In addition to the shredding hammers and chipping
knives, the rotor has four fan blades integrated into its
design. When the rotor is spinning, a vacuum action is
created, which pulls waste down into the shredder hop-
per and into the grinding chamber.
These spinning fan blades also create a blowing force
that ejects the shredded or chipped material out of the
discharge chute, making room for more material to be
pulled in and processed.
Optional Vacuum Attachment
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
greatly simplifies the processing of leaves and other
loose waste. The vacuum kit attaches directly to the back
of the grinder, and after a cover is placed over the shred-
der hopper, the vacuum action is diverted 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
12
different situations by turning a sleeve on the assembly.
SITE LOCATION
1. Select an area with firm, level ground, covered by dirt
or grass. Do not operate on wet, slick surfaces, or in
areas with heavy pedestrian traffic.
2. Locate the unit near the waste materials to be
processed to reduce lifting and carrying.
3. Trim and stack the materials for more efficient and
safe operation of the chipper/shredder unit.
4. 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 mate-
rials to be processed. |
5.. Review all operating safety instructions before pro-
ceeding.
À DANGER
internal combustion engines produce Carbon
Monoxide, a colorless, odorless, and tasteless
gas that can cause dizziness, nausea, uncon-
sciousness, and even brain damage or death if
inhaled for prolonged periods.
Operate the chipper/shredder outdoors in a well
ventilated location only.
Keep children, pets, and bystanders away from
the operating and discharge areas.
Failure to follow these instructions may result in
serious injury or death to you or bystanders.

CHECKS BEFORE STARTING
All Models
_ 1. Inspect the chipper cone and shredder hopper for
debris and other objects that may have fallen into the
machine while the unit was idle, and remove them
before starting the unit. Before reaching into the
openings, always disconnect the spark plug wire or
power cord.
2. Inspect the chipper cone and shredder hopper, and
make sure that they are firmly attached to the hous-
ing.
3. Check all parts to ensure that they are properly
attached and that all fasteners are properly tightened.
4. Make sure the discharge chute deflector pivots freely,
allowing mulch to be discharged freely. If the deflec-
tor does not pivot, loosen the mounting screw slightly
to reduce tension on the pivot point.
5. Before attempting to start the unit, make sure:
+ all hardware and parts are properly secured;
° no foreign objects are in chipper cone or shredder
hopper;
¢ your clothing is not excessively loose or hanging
down, and you are not wearing jewelry or other
articles that could get caught in the machinery.
Model 3/10 8 5/10
1. Make sure oil level in engine is full.
2. Be sure that no fuel has spilled onto engine or sur-
rounding components.
START-UP
Model 2/10 —
The model 2/10 chipper/shredder requires no special
adjustments to be started. Turn the motor on, allow the
rotor to attain full speed then commence normal chipping
and shredding operation.
- Models 3/10 € 5/10
The controls required to start and run the chipper/
shredder are located on the engine and are marked
“Choke” and “Throttle”.
A more detailed description of engine operation and all
related precautions and procedures can be found in the
engine manufacturer's manual that accompanies each
chipper/shredder.
COLD STARTS
1. Move choke lever to full choke position.
Operation
2. Move throttle lever to “start”.
3. Place foot on front support leg to hold unit firmly in
place, and adopt a stable stance.
4. Pull starting rope out slowly one time and allow to
return normally.
5. Pull starting rope out rapidly, and allow rope to return
normally.
6. When engine starts, gradually move choke lever to
“no choke” position and increase throttle speed.
7. Adjust throttle speed to “high” for best chipper/shred-
der action. |
RESTARTING A WARM ENGINE
Restarting an engine that is already warm from previous
running does not normally require use of the choke.
1. Move throttle lever to “start” position.
2. Place foot on front support leg to hold unit firmly in
place, and adopt a stable stance.
3. Pull starting rope out rapidly until engine starts. Allow
rope to return normally.
4. Adjust throttle speed to “high” for best chipper/shred-
der action.
IDLE SPEED
Use the “low” position on the throttle lever to reduce
stress on the engine when chipping or shredding is not
being performed. Lowering the engine speed to “idle”
the engine will help extend the life of the motor, as well
as conserve fuel and reduce the noise level of the equip-
ment.
: OPERATING SPEED
For normal chipping, shredding, and vacuuming opera-
tion, set the throttle lever to “fast”.
OPERATING INSTRUCTIONS
General
Your Chipper/Shredder is easy to set up and operate,
but requires simple precautions that are very important,
but easy to foilow.
Please review the following instructions and illustrations
carefully. Always comply with these and all other safety
and operating instructions in this manual, and on warning
labels on the chipper shredder unit, whenever handling
or operating this machinery.
Always wear safety goggles when operating the chip-
per/shredder. Never allow anyone to operate the unit or
remain in the immediate area unless they are wearing
approved safety goggles.
Operation
*2573
Figure 8. Proper Stance for Chipping
Proper Stance 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 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 or shred-
der hopper area. |
Leaves and other lightweight organic matter can be
quickly shredded in your chipper/ shredder and reduced
to 1/20th of their original volume. Place material to be
shredded into the shredder hopper. Avoid large amounts
of wet material that can cause shredded matter to build
up in the discharge chute and prevent proper discharge.
Alternate the processing of dry and wet materials to help
prevent clogging of the discharge chute. When time per-
mits, let wet material dry out for a few days prior to.
shredding.
Properly Feeding Longer Materials
For Shredding — |
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 the spark plug before attempting to
clear the hopper. |
NOTE: Be sure to shut off the unit and allow the rotor to
stop completely before emptying the bag.
Operation
MATERIAL PROCESSING
General
Most materials to be processed can be handled more
efficiently by observing the following chipper/shredder
operating tips: |
Shredding
1. Don't overioad the shredder hopper by dumping large
volumes of material into the hopper opening.
2. Alternate wet and dry material to prevent the dis-
charge chute from becoming plugged.
3. Never use any object to force material into the shred-
der chamber. It could get caught in the shredding
hammers and damage the unit, reducing shredder
hammer effectiveness.
Chipping
1. Prune tree limbs and large branches to limit 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 easi-
er, and will help you maintain control as the material
is drawn into the chipper block.
2. Large, hard, or dried-out tree limbs that tend to resist
chipping can be processed by rotating them manually
as you alternately insert and retract them in the chip-
per cone. |
3. If the material to be chipped is extremely hard and kicks
back forcefully, or cannot be easily controlled while it is
being fed into the unit, remove the material immediately
and set it aside. You may need to sharpen the chipper
blades to process the material. Consult the mainte-
nance and service section of this manual for sharpen-
ing instructions, or take your unit to an authorized ser-
vice center for prompt, reliable service.
4, If normal chipping operation begins to require additional
feeding force to process material, the chipper knives
may be in need of routine sharpening. See the mainte-
nance and service section of this manual for sharpen-
ing instructions, or take your unit to an authorized ser-
vice center for prompt, reliable service.
. Always try to maintain adequate control of the tree o
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.
Cut any left-over material into 1" pieces and process
them through the shredder hopper.
Bagging
The bag attachment provides an efficient method for col-
lecting discharged material. To install the bag, use the
following procedure.
1.
2.
Disconnect the spark plug wire or power cord.
Put the bag over the discharge deflector and chute.
Lift the deflector up and secure the bag cinch.
Check the discharge deflector for proper movement.
Lay the bag fiat on the ground, perpendicular to the
unit for best collection of material.
À WARNING
Never attach, remove or adjust the bag while the
unit is running. Always shut the unit off, allow
the rotor to come to a complete stop, and dis-
connect the spark plug wire or power cord.
Failure to obey these instructions may result in
serious injury.
15
Operation
SHUTTING DOWN
À DANGER
Gasoline engine and surrounding parts become
extremely hot during normal use, and will cause
serious burn injuries if touched before the
engine has cooled.
Allow engine to cool completely before touching
these hot surfaces.
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 trou-
ble-free.
1. When you have completed processing the materials
to be chipped or shredded, shut the unit off and allow
the rotor to come to a complete stop before proceed-
ing. |
2. On gasoline powered models, remove the spark plug
wire from the spark plug to prevent the possibility of
inadvertent starting. On electric models, unplug the
power cord.
3. Inspect the following areas for any remaining materi-
als that may have built up or become caught during
the final chipping and shredding operations:
SHREDDER HOPPER
Visually inspect inside of shredder hopper, and
remove any material remaining inside.
CHIPPER CONE
Visually inspect chipper cone to ensure that there
are no pieces of tree limbs, branches, or any other
debris remaining inside. Remove and discard any
debris.
DISCHARGE CHUTE
Lift the discharge deflector, inspect the chute for
clogs or other build up, and remove as required.
This area is most likely to require clean out if wet
or green organic materials have been shredded.
MOTOR COOLING VENTS - MODEL 2/10
The curved slots in the motor housing allow air
cooling of the motor. Remove any build up of
debris or shredded material that may block air flow
around the motor.
ENGINE RECOIL STARTER AREA - MODELS
3/10 & 5/10
This area of the engine is also the intake for the
motor's air cooling fans. Remove any build-up of
grass or shredded material that may have accu-
mulated around the intake openings. Use care to
prevent build-up from being pushed into the intake
area during cleaning.

Models 3/10 & 5/10
OIL LEVEL
1. Oil level must be full. The engine is equipped with an
oil dipstick. Oil level should be between the “Full” and
“Add” mark on the dipstick. See figure 11.
2. Add SAE 30 oil (5W30 for winter Use) as necessary,
and check level by wiping fill plug-dipstick clean,
screwing it all the way in, then removing it completely.
3. Do not overfill the oil sump! Excess oil will result in
frothing of oil, reducing the effectiveness of the oil
and shortening engine life. |
À WARNING
Never drain oil immediately after running the
chipper/shredder, as it will be hot and could
cause burns if allowed to splash onto your
hands or body.
4. After the proper oil level is reached, screw the fill plug
in tightly. Clean surrounding area of any spillage to
prevent sticking of debris that could fall into engine
during 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 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 in engine
base and letting oil drain into a suitable container.
2. Dispose of 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.
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.

Normal Care
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, screw the new plug in and tighten. Don’t
over tighten, as this could crack the porcelain insula-
tor and ruin the plug.
CLEAN ENGINE FINS/AIR INTAKE 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 head area must also be
kept clear of chipper/shredder deposits, as well as any
other build-up of debris that could prevent heat from radi-
ating away from the engine.
To clean the air intake area, remove any chipper/shred-
der 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 aut
parts supply stores. Ä
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 cleaner aerosol may help loosen and remove the
deposits. If you use such a product, you must follow all
safety and use instructions to prevent damage to the
engine components and personal injury to you.
Using a stream of water to clean the engine requires
immediate drying of engine components to prevent rust-
ing and possible malfunctioning of the electrical system.
CLEAN/OIL/REPLACE AIR FILTER ELEMENT
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:
* clean and oil the air filter (foam filter only),
* only clean the air filter (Type “A” filter),
* or replace the filter every year or 100 hours of opera-
_ tion (paper filter element).
Consult the engine manufacturer's manual provided with
your chipper/shredder for the specific instructions that
apply to your unit. |
If you have any doubts about what type of filter element
you have, consult you local authorized dealer for help in
replacing or ordering the correct element.

INSPECT STARTER ROPE/HANDLE
The recoil starter rope and handle should be inspected for
signs of abrasion or wear that could result in breakage.
Don’t use worn out parts, since they could break while
tension is applied to the rope, throwing you off balance.
Contact your local authorized dealer for replacement if
these parts need to be replaced.

INSPECT/ROTATE SHREDDING HAMMERS
The patented shredding hammers on this line of chip-
per/shredders can be easily rotated to provide new cut-
ting surfaces as required. —
Triangular hammers can be rotated twice, then flipped
over for a total of six sharp, new leading edges. “J” ham-
mers on the Model 5/14 can be flipped over once, for a
total of two sharp, new leading edges. |
lf the shredding action of the unit seems sluggish, or you
notice that shredded material is not shredded as thor-
oughly as when the unit was new, the shredding ham-
mers may need to be rotated or replaced.
Rotating the shredder hammers requires the following
major steps:
1. Removal of the shredder hopper
2. Removal of the rotor housing
3. Removal, rotation, and/or replacement of the shred-
der hammers
4. Replacement of the rotor housing
5. Replacement of the shredder hopper

Your local authorized dealer can provide this service to
you if you do not wish to disassemble the unit and
inspect/repair it yourself.
INSPECT/SHARPEN CHIPPING KNIVES
This unit's high-quality chipping knives are manufactured
from a high-quality precision tempered steel, and are
designed to provide positive feeding of tree limbs and
branches, as well as exceptionally long service life.
Normal chipping operations will gradually wear the cut-
ting edges of these blades, but the rugged design and
tough material used allows them to be quickly and easily
resharpened for long-lasting, like-new performance.
When tree limbs and branches begin to require addition-
al pressure to feed into the chipping knives, it may be
time to sharpen the cutting edges to return them to their
original performance.
Sharpening the cutting knives requires the following
major steps:
Removal of the shredder hopper.
Removal of the chipper cone.
Removal of an access plug.
Removal of the cutting knives.
Careful, low-speed, wet grinding of a new edge.
Reassembly of the cutting knives to the oval chipping
block.

per to the unit.
Consult the Troubleshooting and Repair Section of this
manual for complete disassembly, inspection, and
replacement instructions.
Your local authorized dealer can provide this service to
you if you do not wish to disassemble the unit and
inspect/repair it yourself.
LUBRICATE WHEEL AXLES |
The low profile and excellent balance of the unit makes
transporting it easy, but constant exposure to dirt, debris,
and chipper/shredder materials requires routine lubrica-
tion of the wheels.
To lubricate, squirt 3-5 drops of SAE 30 oil on each
wheel axle. Wipe up any run-off and spin wheels briefly
to work oil around entire axle. |
CHECK SAFETY LABELS
The safety labels located in various positions on the
chipper/shredder have been placed to help remind you of
important safety rules while you are running the chip-
per/shredder unit.
While these labels are extremely durable, constant abra-
sion from tree limbs and branches can eventually affect
their readability. Check each label to make sure it is still
properly affixed to the chipper/shredder, and is still com-
pletely legible.
If any label can't be read or is missing, contact your local
dealer for an immediate replacement. lf you must use the
unit without the label, review the label information in the
“Safety Labels” section of this manual.
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.
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. |
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.
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 oper-
ator.
The hopper guards must always be intact and properly
installed to provide protection from ejected pieces.
Ifa 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.
Storage
TEMPORARY STORAGE
(30 Days Or Less)
All Models
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.
* 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.
Models 3/10 & 5/10
¢ If there’s any chance of unauthorized use, remove
the spark plug, and put it in a safe place. Be sure to
protect the spark plug opening from foreign objects
with a suitable cover.
Remember, the chipper/shredder fuel tank probably
will still contain some gasoline, so 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 chip-
per/shredder in any structure used for human or ani-
mal habitation.
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

A WARNING
Hammer and chipper knife cutting edges are
sharp. Wear leather work gloves to protect your
hands from injury.
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 the figure 21. To service
the chipping knives, follow these steps.
1. Turn the unit off, allow rotor to stop completely and
disconnect the spark plug wire or power cord.
-2. Remove the chipper cone to expose one chipping
knife. See figure 22. | |
3. Remove the two socket capscrews and chipper knife.

will soften the edges, making repeated sharpening
necessary.
* Chipper knives require a 30° bevel on the cutting
edge (as shown in figure 21) for efficient chipping |
action.

À WARNING
Never use a malfunctioning unit to process
material, even if it appears to be chipping materi-
al adequately. An unexpected kick-back could
occur, causing serious personal injury to you or
bystanders.
Serious equipment damage could also result,
voiding the warranty and requiring extensive
repairs by a qualified service location.
Deflector Shield
The deflector shield must pivot freely at all times, or
processed material could back up, clogging the unit and
requiring disassembly to clear.
_ ФМААММС
Never use the unit unless the deflector shield is
in place and operating properly. .
Material could be ejected out of the discharge
chute with great force, injuring you or
bystanders. |
