SPECIAL NOTICE; For users on U.S.

Forest Land and in some states, in-

cluding California(Public Resources

Codes 4442 and 4443), Idaho, Maine,

Minnesota, New Jersey, Oregon, and

Washington: Certain internal combus-

tion engines operated on forest, brush,

and/or grass covered land in the above

areas are required to be equipped with

a spark arrestor, maintained in effective

3

working order, or the engine must be

constructed, equipped, and maintained

for the prevention of fire° Check with

your state or local authorities for regu-

lations pertaining to these require-

ments. Failure to follow these require-

ments is a violation of the law. This unit

is not factory equipped with a spark ar-

restor; however, a spark arrestor is

available as an optional part. If a spark

arrestor is required in your area, con-

tact Sears Service for the correct kit.

The spark arrestor, blower tubes, and

nozzles must be assembled to unit to

be in full compliance with regulations.

SPECIAL NOTICE: Exposure to vibra-

tions through prolonged use of gaso-

line powered hand tools could cause

blood vessel or nerve damage in the

fingers, hands, and joints of people

prone to circulation disorders or abnor-

mal swelling. Prolonged use in cold

weather has been linked to blood ves-

sel damage in otherwise healthy

people, if symptoms occur such as

numbness, pain, loss of strength,

change in skin color or texture, or loss

of feeling in the fingers, hands, or

joints, discontinue the use of this tool

and seek medical attention. An

antivibration system does not guaran-

tee the avoidance of these problems.

Users who operate power tools on a

continual and regular basis must moni-

tor closely their physical condition and

the condition of this tool.

ENGINE STOP BUTTON

The engine stop button is used to stop

the engine_ To STOP the engine,

press and hold the button in the STOP

PRIMER BULB

The primer bulb removes air from the

fuel lines and fills them with fuel. This

allows you to start the engine with few-

er pulls on the starter rope. Activate the

primer bulb by pressing it and allowing

it to return to its original form.

CHOKE

The choke helps to supply fuel to the

carburetor during starting. This allows

you to start a cold engine. Activate the

choke by moving the choke lever to the

Full or Half position° After the engine

has started, move the choke lever to

the Full Throttle position.

BEFORE STARTING ENGINE

WARNING: Be sure to read the fuel

information in the safety rules before

you begin. If you do not understand the

safety rules, do not attempt to fuel your

uniL Call !-800-235-587&

FUELING ENGINE

This engine is certified to operate on

unleaded gasoline. Before operation,

gasoline must be mixed with a good

quality 2-cycte air-cooled engine oil.

We recommend Craftsman brand oil.

Mix gasoline and oil at a ratio of 40: I

(A 40:1 ratio is obtained by mixing 32

ounces of oil with 1 gallon of unleaded

gasoline). DO NOT USE automotive oil

or boat oil. These oils will cause engine

Rear Handle

damage. When mixing fuel, follow

instructions printed on container.

Once oil is added to gasoline, shake

container momentarily to assure that

the fuel is thoroughly mixed. Always

read and follow the safety rules relating

to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract mois-

ture which leads to separation and

formation of acids during storage° Acid-

ic gas can damage the fuel system of

an engine while in storage°

To avoid engine problems, empty the

fuel system 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,

Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur.

information.
