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.
DANGER: 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.

and equipment. Move machine to another
area. Wait 5 minutes before starting the
engine.
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.
3
i. 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.)
j. To reduce a fire hazard, keep machine free
of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove any
fuel soaked debris.
9. Never operate without either the inlet nozzle or
optional hose attachment 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 gravel 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.
k. Allow machine to cool at least 5 minutes
before storing.
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.
16. Never pick up or carry machine while the engine is
running.
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.
MAINTENANCE AND STORAGE
1. Never tamper with safety devices. Check their
proper operation regularly.
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:
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.
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. Zippered end of vacuum bag must be kept
closed at all times during operation.
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.

(Bottom Position)
Yard waste such as leaves and pine needles can be
vacuumed up through the nozzle for shredding. After
material has been shredded by the flail blades on the
impeller assembly, it will be discharged into catcher bag
or through blower chute. 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. Materials such as stalks or heavy branches
up to 1 1/2” in diameter may be fed into the chipper
chute.
