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.

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.

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.

instruction.

Keep bystanders, 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.

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.

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.

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.

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.

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.

Extinguish all cigarettes, cigars, pipes and other sources of
ignition.

Never fuel machine indoors.

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 ½
inch below bottom of filler neck to allow space for fuel
expansion.

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.
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.

Section 2 — Important Safe Operation Practices

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.

Repair or replace any damaged parts.

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.

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.

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.
