The engine manufacturer is responsible for all engine-related issues with regards to
performance, power-rating, specifications, warranty and service. Please refer to the engine
manufacturer's Owner's/Operator's Manual, packed separately with your unit, for more
information.

SECTION1: IMPORTANT
SAFEOPERATION
PRACTICES
WARNING:

This symbol points out important safety instructions which, if not followed, could
endanger the personal safety and/or property of yourself and others. Read and follow all instructions in
this manual before attempting to operate this machine. Failure to comply with these instructions may
result in personal injury. When you see this symbol - heed its warning.

WARNING:

The Engine Exhaust from this product contains chemicals

birth defects or other reproductive

known to the
harm.

This machine was built to be operated according to the rules for safe operation in this

manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.

TRAINING
1.

4.
5.

Read, understand, and follow all instructions on the
machine and in the manual(s) before attempting to
assemble and operate. Keep this manual in a safe
place for future and regular reference and for
ordering replacement parts.
Be familiar with all controls and their proper
operation. Know how to stop the machine and
disengage them quickly.
Never allow children under 16 years old to operate
this machine. Children 16 years old and over
should read and understand the operation
instructions and safety rules in this manual and
should be trained and supervised by a parent.
Never allow adults to operate this machine without
proper instruction.
Keep bystanders, helpers, pets, and children at
least 75 feet from the machine while it is in
operation. Stop machine if anyone enters the area.
Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless and deadly gas.
Do not put hands and feet near rotating parts or in
the feeding chambers and discharge opening.
Contact with the rotating impeller can amputate
fingers, hands, and feet.
Never attempt to unclog either the feed intake or
discharge opening, remove or empty bag, or
inspect and repair the machine while the engine is
running. Shut the engine off and wait until all
moving parts have come to a complete stop.
Disconnect the spark plug wire and ground it
against the engine.

PREPARATION
,

Thoroughly inspect the area where the equipment
is to be used. Remove all rocks, bottles, cans, or
other foreign objects which could be picked up or
thrown and cause personal injury or damage to the
machine.

Always wear safety glasses or safety goggles
during operation or while performing an adjustment
or repair, to protect eyes. Thrown objects which
ricochet can cause serious injury to the eyes.
,
Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Loose fitting clothes or
jewelry can be caught in movable parts. Never
operate this machine in bare feet or sandals. Wear
leather work gloves when feeding material in the
chipper chute.
,
Before starting, check all bolts and screws for
proper tightness to be sure the machine is in safe
working condition. Also, visually inspect machine
for any damage at frequent intervals.
,
Maintain or replace safety and instructions labels,
as necessary.
6. To avoid personal injury or property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes, and
other sources of ignition.
c. Neverfuel machine indoors.
,

d.
e.
f.

g.
h.

Never remove gas cap or add fuel while the
engine is hot or running.
Allow engine to cool at least two minutes
before refueling.
Never over fill fuel tank. Fill tank to no more
than 1/2 inch below bottom of filler neck to
provide space for fuel expansion.
Replace gasoline cap and tighten securely.
If gasoline is spilled, wipe it off the engine
and equipment. Move machine to another
area. Wait 5 minutes before starting the
engine.
Never store the machine or fuel container
inside where there is an open flame, spark,
or pilot light (e.g. furnace, water heater,
space heater, clothes dryer, etc.)

OPERATION
1.

Do not put hands and feet near rotating parts or in
the feeding chambers and discharge opening.
Contact with the rotating impeller can amputate
fingers, hands, and feet.
Before starting the machine, make sure the chipper
chute, feed intake, and cutting chamber are empty
and free of all debris.
Thoroughly inspect all material to be shredded and
remove any metal, rocks, bottles, cans, or other
foreign objects which could cause personal injury
or damage to the machine.
If it becomes necessary to push material through
the shredder hopper, use a small diameter stick. Do
not use your hands or feet.
If the impeller strikes a foreign object or if your
machine should start making an unusual noise or
vibration, immediately shut the engine off. Allow the
impeller to come to a complete stop. Disconnect
the spark plug wire, ground it against the engine
and perform the following steps:
a. Inspect for damage.
b. Repair or replace any damaged parts.
c. Check for any loose parts and tighten to
assure continued safe operation.
Do not allow an accumulation of processed
material to build up in the discharge area. This can
prevent proper discharge and result in kickback of
material through the feed opening.
Do not attempt to shred or chip material larger than
specified on the machine or in this manual.
Personal injury or machine damage could result.
Never attempt to unclog either the feed intake or
discharge opening while the engine is running.
Shut the engine off, wait until all moving parts have
stopped, disconnect the spark plug wire and
ground it against the engine before clearing debris.
Never operate without the shredder hopper,
chipper chute, or chute deflector properly attached
to the machine. Never empty or change discharge
bag while the engine is running.

10. Keep all guards, deflectors and safety devices in
place and operating properly.
11. Keep your face and body back and to the side of
the chipper chute while feeding material into the
machine to avoid accidental kickback injuries.
12. Never operate this machine without good visibility
or light.
13. Do not operate this machine on a paved, gravel or
non-level surface.
14. Do not operate this machine while under the
influence of alcohol or drugs.
15. Muffler and engine become hot and can cause a
burn. Do not touch.
16. Never pick up or carry machine while the engine is
running.

MAINTENANCE
ANDSTORAGE
1.

Never tamper with safety devices. Check their
proper operation regularly.
2. Check bolts and screws for proper tightness at
frequent intervals to keep the machine in safe
working condition. Also, visually inspect machine
for any damage and repair, if needed.
3. Before cleaning, repairing, or inspecting, stop the
engine and make certain the impeller and all
moving parts have stopped. Disconnect the spark
plug wire and ground it against the engine to
prevent unintended starting.
4. Do not change the engine governor settings or
overspeed the engine. The governor controls the
maximum safe operating speed of the engine.
5. Maintain or replace safety and instruction labels, as
necessary.
6. Follow this manual for safe loading, unloading,
transporting, and storage of this machine.
7. Never store the machine or fuel container inside
where there is an open flame, spark or pilot light
such as a water heater, furnace, clothes dryer, etc.
8. Always refer to the operator's manual for proper
instructions on off-season storage.
9. If the fuel tank has to be drained, do this outdoors.
10. Observe proper disposal laws and regulations for
gas, oil, etc. to protect the environment.

UsingThe ChipperShredder
Yard waste such as leaves and pine needles can be
raked up through the hopper assembly for shredding.
After material has been shredded by the flail blades on
the impeller assembly, it will be discharged out of
opening or into catcher bag. Do not attempt to shred or
chip any material other than vegetation found in a
normal yard (i.e. branches, leaves, twigs, etc.) Avoid
fibrous plants such as tomato vines until they are
thoroughly dried out. Twigs and small branches up to 3"
in diameter on select models 462 thru 465 and 2" in
diameter on model 463 can be fed into the chipper
chute. If equipped, use the tamper plug to push material
into the chipper chute. See Figure 8.
