Important Safe Operation Practices 2
3
Training
1. 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.
2. Be familiar with all controls and their proper
operation. Know how to stop the machine and
disengage them quickly.
3. Never allow children under 16 years of age to
operate this machine. Children 16 and over
should read and understand the instructions
and safe operation practices in this manual
and on the machine and be trained and
supervised by an adult.
4. Never allow adults to operate this machine
without proper instruction.
5. Keep bystanders, pets, and children at least 75
feet from the machine while it is in operation.
Stop machine if anyone enters the area.
6. Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains
carbon monoxide, an odorless and deadly gas.
7. 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.
8. 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
1. 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.
2. Always wear safety glasses or safety goggles
during operation and while performing an
adjustment or repair, to protect your eyes.
Thrown objects which ricochet can cause
serious injury to the eyes.
3. Wear sturdy, rough-soled work shoes and
close-fitting 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.
4. 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.
5. Maintain or replace safety and instructions
labels, as necessary.
Safe Handling of Gasoline:
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.
1. Use only an approved gasoline container.
2. Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner. Always
place containers on the ground away from
your vehicle before filling.
3. When practical, remove gas-powered
equipment from the truck or trailer and refuel
it on the ground. If this is not possible, then
refuel such equipment on a trailer with a
portable container, rather than from a gasoline
dispenser nozzle.
4. Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times
until fueling is complete. Do not use a nozzle
lock-open device.
5. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
6. Never fuel machine indoors.
7. Never remove gas cap or add fuel while the
engine is hot or running. Allow engine to cool
at least two minutes before refueling.
8. Never over fill fuel tank. Fill tank to no more
than ½ inch below bottom of filler neck to
allow space for fuel expansion.
9. Replace gasoline cap and tighten securely.
10. If gasoline is spilled, wipe it off the engine and
equipment. Move unit to another area. Wait 5
minutes before starting the engine.
11. To reduce fire hazards, keep machine free of
grass, leaves, or other debris build-up. Clean
up oil or fuel spillage and remove any fuel
soaked debris.
12. Never store the machine or fuel container
inside where there is an open flame, spark or
pilot light as on a water heater, space heater,
furnace, clothes dryer or other gas appliances.
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.
2. Before starting the machine, make sure
the chipper chute, feed intake, and cutting
chamber are empty and free of all debris.
3. 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.
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!
DANGER: This machine was built to be operated according to the safe operation practices 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 fingers, hands, toes and feet and
throwing debris. Failure to observe the following safety instructions could result in serious injury or death.
CALIFORNIA PROPOSITION 65
WARNING: Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to State of California to cause
cancer and birth defects or other reproductive harm.
4. 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.
5. 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.
6. 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.
7. 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.
8. Never operate without vacuum bag and
discharge chute properly attached to the
machine. Never empty or change vacuum bag
while the engine is running. Vacuum bag must
be kept closed at all times during operation.
9. Never operate without either the inlet nozzle
or optional hose attachment (if applicable)
properly attached to the machine. Never
attempt to attach or change either attachment
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. Always be sure of your
footing and keep a firm hold on the handles.
13. Do not operate this machine on a paved,
gravel or non-level surface.

a burn. Do not touch.
16. Never pick up or carry machine while the
engine is running.
17. If situations occur which are not covered in
this manual, use care and good judgement.
Contact Customer Support for assistance and
the name of the nearest service dealer.

• When storing the chipper/shredder
vacuum in an unventilated or metal
storage shed, care should be taken to
rustproof the non-painted surfaces. Using
a light oil or silicone, coat the equipment,
especially any springs, bearings, and
cables.
• Remove all dirt from exterior of engine
and equipment.
• Follow lubrication recommendations.
• Refer to engine manual for correct engine
storage instructions.
• Store equipment in a clean, dry area. Do
not store in an area where equipment is
present that may use a pilot light or has a
component that can create a spark.
