GENERAL OPERATION
• Read this owner’s guide carefully in its entirety before
attempting to assemble this machine. Read,
understand, and follow all instructions on the machine
and in the manual(s) before operation. Be completely
familiar with the controls and the proper use of the
machine before operating it. Keep this manual in a
safe place for future and regular reference and for
ordering replacement parts.
• Your chipper-shredder is a powerful tool, not a
plaything. Therefore, exercise extreme caution at all
times. Your unit has been designed to perform two
jobs; to chip and shred vegetation found in a normal
yard. Do not use it for any other purpose.
• Never allow children under age 16 to operate the unit.
Children 16 years and older should only operate the
unit under close parental supervision. Only
responsible individuals who are familiar with these
rules of safe operation should be allowed to use your
unit.
• Keep the area of operation clear of all persons,
particularly small children and pets. Stop the engine
when they are in the vicinity of the unit. Keep work
area clean and clear of branches or obstacles which
could cause you to stumble or fall.
• When feeding material into this equipment, be
extremely careful that pieces of metal, rocks, bottles,
cans or other foreign objects are not included.
Personal injury or damage to the machine could result.
• Always wear safety glasses or safety goggles, during
operation and while performing an adjustment or
repair, to protect eyes from foreign objects that may be
thrown from the machine.
• Wear stu rdy, rough-so led wo rk shoes and close f itti ng
slacks and shirt. Shirt and slacks that cover the arms
and legs and steel-toed shoes are recommended. Do
not wear loose fitting clothes or jewelry and secure hair
so it is above shoulder length. They can be caught in
moving parts. Never operate a unit in bare feet,
sandals or sneakers. Wear gloves when feeding
material in the chipper chute or shredder hopper.
• Never place your hands, feet, or any part of your body
into the shredder hopper, chipper chute, discharge
opening, or near any moving part while the engine is
running. Keep clear of the discharge opening at all
times. If it becomes necessary to push material into
the chipper chute or shredder hopper, use a small
diameter stick, NOT YOUR HANDS,
If it is necessary for any reason to unclog the feed
intake or discharge openings or to inspect or repair any
part of the machine where a moving part can come in
contact with your body or clothing, stop the machine,
allow it to cool, disconnect the spark plug wire from the
spark plug and move it away from the spark plug
before attempting to unclog, inspect or repair.
Do not operate unit while under the influence of alcohol
or drugs.
The machine should only be operated on a level
surface. Never operate your unit on a slippery, wet,
muddy or icy surface. Keep your work area clean and
clear of branches or obstacles which could cause you
to stumble and fall. Do not overreach. Maintaining
proper footing and balance is essential to preventing
accidents.
Do not allow an accumulation of processed material to
build-up in the discharge area as this will prevent
proper discharge and can result in kick-back from the
chipper chute.
Keep your face and body back from chipper chute to
avoid accidental bounce back of any material.
Do not transport machine while engine is running.
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.
a. Inspect for damage.
b. Repair or replace any damaged parts.
c. Check for any loose parts and tighten to assure
continued safe operation.
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.
Muffler and engine become hot and can cause a burn.
Do not touch.
• Do not allow leaves or other debris to build-up on
engine’s muffler. The debris could ignite and cause a
fire.
• 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

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.
CHILDREN
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.
• Keep children out of the work area and under the
watchful eye of a responsible adult other than the
operator.
• 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.
SERVICE
c. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
d. Never refuel unit indoors because flammable
vapors will accumulate in the area.
e. 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.
• 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.
• To reduce fire hazard, keep engine and mufflerfreeof
leaves, grass, and other debris build-up. Clean up
fuel and oil spillage. Allow unit to cool at least 5
minutes before storing.
• 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.
• 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 all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
• Nevertamper with safety devices. Check their proper
operation regularly,
• 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.
• Do not alter or tamper with the engine's governor
setting. The governor controls the maximum safe
operating speed of the engine. Over-speeding the
engine is dangerous and will cause damage to the
engine and to other moving parts of the machine.
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the vapors
are explosive.
a. 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.
b. Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it
may cause a fire or explosion.
This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forestcovered, 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
Àk
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 Sears Authorized Service Center (See the REPAIR PARTS section of this manual.)
