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 dear 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 dear 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
repdr, to protect eyes from foreign objects that may be

thrown from the machine.

• Wear sturdy, rough-soled work shoes and dose fittirtg
slacks and shirt Shirt and slacks that cover the arms
and legs and steel-toed shoes are recommended. Do
not wear loose fitting dothes or jewelry and secure hair
50 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 dear 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 cf proceed material to

build up in the discharge area as this will prevent

proper discharge and csm result in kick-back from the
chi];^er 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.

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 underthe age of 16 to operate the

chipper-shredder.

SERVICE

• 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 geis 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 an;

spilled gasoline before starting the engine as it

may cause a fire or explosion.

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 orfuei container inside

where there is an open flame or spark such as a _
gas hot water heater, space heater, clothes dryer
orftjrnace.

• 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 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.

• 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 writh blades which meet original
equipment specifications.

• Keep all nuts, bolts, and screws tight to be sure the

equipment is in safe working condition.

• Never tamper 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.

• Only use high quality detergent oil rated with
API service classification SF, SG or SH. Select
the oil's viscosity grade according to your

expected operating temperature. Follow the

chart below.

Colder

32®F

Warmer

Add oil, if necessary, to bring the oil level to

FULL mark on the dipstick.

• Replace dipstick and tighten.
NOTE: Do not overfill. Oil bottles packed with unit

contain a total of approximately 40 oz. of oil.

Gasoline
WARNING: Experience indicates that alcohol

blended fuels (called gasohol or using ethanol or

metiianol) can attract moisture which leads to
separation and fonnation of acids during storage.

Acidic gas can damage the fuel system of an engine

while in storage. To avoid engine problems, the fuel
system should be emptied before storage for 30
days or longer. Drain the gas tank, start the engine
and let it run until the fuel lines and carburetor are
empty. Use fresh fuel next season. See STORAGE
instructions for additional information. Never use
engine or carburetor cleaner products in the fuel tank
or permanent damage may occur.

Fill gasoline tank as follows.

• Remove fuel cap.

• Make sure the container (from which you will

pour the gasoline) is clean and free from rust or
foreign particles. Never use gasoline that may
be stale from long periods of storage in the
container.

• Fiii fuel tank with clean, fresh, lead-free

automotive gasoline. DO NOT use Ethyl or high
octane gasoline. See Figure 11. Replace fuel
cap.

Remove cap

NOTE: AJthough multi-viscosity oils (5W30,10W30,

etc.) improve darting in cold weather, these
multiviscosity oils mil result in increased oil

consumption when used above 40* *’F. Check the dl
level more frequently to avoid possS^e engine
damage from running low on oil.

Fill engine with oil as follows.

• Remove oil fill dipstick. See Figure 11.

• With chipper-^redderon level ground, use a funnel
to fill engine wHh oil to FULL mark on dipstick.

Capacity is af^roximately 40 ounces. Be careful not
to overfill. Replaoe dipstick and lights.

• Start and run engine for 30 seconds. Shut

engine off. Wait 30 seconds and dieck oil level.
