This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest-
Warning:
covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting
applicable local or state laws (if any). If a spark arrester is used, it should 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. A spark arrester for the muffler is available through your nearest engine authorized
service dealer or contact the service department, P.O. Box 368022 Cleveland, Ohio 44136-9722.

• If the cutting mechanism strikes a foreign object or if
your machine should start making an unusual noise
or vibration, immediately stop the engine and allow
the machine to come to a complete stop. Disconnect
the spark plug wire and move it away from the spark
plug. Take the following steps.
3. SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the vapors
are explosive.
• Store fuel and oil in approved containers, away from
heat and open flame, and out of the reach of
children. Check and add fuel before starting the
engine. Never remove gas cap or add fuel while the
engine is running. Allow engine to cool at least two
minutes before refueling.
•
•
•
Inspect for damage.
Repair or replace any damaged parts.
Check for any loose parts and tighten to assure
continued safe operation.
• Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it may
cause a fire or explosion.
• Never attempt to attach or remove catcher bag when
engine is running. Shut the engine off and wait for
the impeller to come to a complete stop. The impeller
continues to rotate for a few seconds after the engine
is shut off. Never place any part of the body in the
impeller area until you are sure the impeller has
stopped rotating.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel unit indoors because flammable vapors
will accumulate in the area.
• Muffler and engine become hot and can cause a
burn. Do not touch.
• Never store the machine or fuel container inside
where there is an open flame or spark such as a gas
hot water heater, space heater, clothes dryer or
furnace.
• Do not allow leaves or other debris to build up on
engine's muffler. The debris could ignite and cause a
fire.
• Never run your machine in an enclosed area as the
exhaust from the engine contains carbon monoxide,
which is an odorless, tasteless and deadly poisonous
gas.
• Do not attempt to shred or chip material larger than
specified in this manual. Personal injury or damage
to the machine could result.
• Do not operate engine if air cleaner or cover over
carburetor air intake is removed, except for
adjustment. Removal of such parts could create a
fire hazard.
• To reduce fire hazard, keep engine and muffler free
of leaves, grass, and other debris build-up. Clean up
fuel and oil spillage. Allow unit to cool at least 5
minutes before storing.
• Only use accessories approved for this machine by
the manufacturer. Read, understand, and follow all
instructions provided with the approved accessory.
• Before cleaning, repairing, or inspecting, make
certain the impeller and all moving parts have
stopped. Disconnect the spark plug wire and keep
wire away from spark plug to prevent accidental
starting. Do not use flammable solutions to clean air
filter.
• If situations occur which are not covered by this
manual, use care and good judgment. Contact your
dealer for assistance.
• Check the blade and engine mounting screws at
frequent intervals for proper tightness. Also visually
inspect blades for wear and/or damage (e.g., bent,
cracked). Replace with blades which meet original
equipment specifications.
• Keep discharge chute deflector, chipper chute door,
and all other guards and safety devices in place and
operating properly.
• Only operate unit in good daylight. Do not operate
unit at night or in dark areas where your vision may
be impaired.
• Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
2. CHILDREN
• Never tamper with safety devices. Check their proper
operation regularly.
Tragic accidents can occur if the operator is not alert to the
presence of small children. Children are often attracted to
the chipper-shredder and the chipping and shredding
activity. Never assume that children will remain where you
last saw them.
• After striking a foreign object, immediately stop the
engine, disconnect the spark plug wire from the
spark plug, and thoroughly inspect the unit for any
damage. Repair damage before starting and
operating unit.
• Keep children out of the work area and under the
watchful eye of a responsible adult other than the
operator.
• Do not alter or tamper with the engine's governor
setting. The governor controls the maximum safe
operating speed of the engine. Overspeeding the
engine is dangerous and will cause damage to the
engine and to other moving parts of the machine.
• Be alert and turn the unit off if a child enters the area.
• Never allow children under the age of 16 to operate
the chipper-shredder.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who read,
understand and follow the warnings and instructions in this manual and on the machine.

sharp. If the composition of the material being
discharged changes (becomes stringy, etc.) or if the
rate at which the material is discharged slows down
considerably, it is likely that the shredding blade and/
or chipper blades are dull and need to be
sharpened or replaced. Refer to Maintenance
section.
CLEANING
• Clean engine periodically. Remove dirt and
debris with a cloth or brush.
• Frequently remove leaves, dirt and debris
from cooling fins, air intake screen and levers
and linkage. This will help ensure adequate
cooling and correct engine speed.

• Clean the chipper shredder by running water
from a hose through the hopper assembly
and chipper chute with the engine running.
Allow the chipper-shredder to dry thoroughly.
SPARK PLUG
• Service the spark plug according to the
separate engine owner’s guide supplied with
your chipper shredder.
NOTE: Cleaning with a forceful spray of water is
not recommended as water could contaminate the
fuel system.
REMOVING THE FLAIL SCREEN
(See Figure 7)
• Wash the bag periodically with water. Allow to
dry thoroughly in the shade. Do not use heat.
If the discharge area becomes clogged, remove the
flail screen and clean area as follows:
1. Stop engine, make certain the chipper-shredder
has come to a complete stop and disconnect
spark plug wire from the spark plug before
unclogging the chute.
2. Remove the two hand knobs on each side of
the discharge chute (also called the chute
deflector).
3. Lift the discharge chute up, and keep it out of
the way.
4. Remove two hairpin clips from the clevis pins
which extend through the housing. Remove the
clevis pins.
ENGINE OIL
The engine oil is the most important “insurance
policy” your new chipper shredder has. It protects it
from excess wear and tear and helps the cooling
process. It is important that you maintain the
engine oil at the proper level and that it is changed
on a regular basis.
• Service the engine oil according to the
separate engine owner’s guide supplied with
your chipper shredder.
5. Pull the flail screen from inside the housing.
6. Clean the screen by scraping or washing with
water.
7. Reinstall the screen.
8. Put the discharge chute back to its original
position and tighten the hand knobs.
AIR CLEANER
The air cleaner prevents damaging dirt, dust, etc.,
from entering the carburetor and being forced into
the engine and is important to engine life and
performance. Never run the engine without air
cleaner completely assembled.
