A. FUELING YOUR ENGINE

1. FUEL SAFETY

a. Use only recommended fuel mixtures.

b. Mix and pour fuel outdoors andwhere there are

no sparks or flames.

c. Use a container approved for fuel,

d. Do not smoke or allow smoking near fuel or the tool

or while using the tool.

e. Wipe up all fuel spills before starting the engine.

f. Move at least 10 feet (3 meters) away from fuel-

ing site before starting engine.

g. Stop engine before removing fuel cap. Allowthe

engine to cool before refueling.

h. Empty fuel tank before storing tool. Use up fuel

left in caJ'buretor by starting engine and letting engine

run until it stops.

i. Store tool and fuel in an area where fuel vapors

cannot reach sparks or open flames from water

heaters, electric motors or switches, furnaces, etc.

_t. FUEL MIX'IIJlt_

• Your tool is powered by a 2-cycle engine which

requires a fuel mixture of regular unleaded gaso-

line and a high quality engine oil specially made

for 2-cycle, air cooled engines. •

The internal design of the 2-cycle engine requires

lubrication of moving parts. Lubrication is provided

when the recommended mixture of gasoline and oil

is used.

• Genuine Sears 40:1,2-cycle engine oil is strongly

recommended for the protection of your unit.

Extensive engineering tests have proven that Sears

2-cycle engine oil resists break-down at operating

temperatures common to 2-cycle engines, resulting

in dependable performance and longer engine life.

• Gasoline must be clean and not over two months

old. After a short period of time, gasoline will chem-

ically break down and form compounds that cause

hard starting and damage in 2-cycle engines.

• The correct measure of gasoline to oil is very

important. Too much oil in the mixture will foul the

spark plug.

I_Lr_tON:I Too little oil or incorrect oil will

cause the engine to overheat and seize.

Always mix the fuel thoroughly in a container

since gasoline and oil do not readily combine. Do not

mix gasoline and oil directly in the fuel tank.

3. USE TIlE FOIJ_WI_G ONLY:

3.2 oz. 2-cycle engine oil to 1 gal. gasoline or 8 oz.

2-cycle engine oil to 2.5 gal. gasoline.

(40 parts gasoline to 1 part oil)

SEARS b_-30143

40:1 Ratio

FJ_GINE OIL (3.2 ozJ

ANY GOOD GRADE

16:1 Ratio

AIR=COOLED, 2_CYCLE

ENGINE OIL (8 oz.)

SEARS 2-cycle engine oil mixed at40:1 is strongly

recommended.

If SEARS 2-cycle engine oil is not available, use a

good quality, 2-cycle engine oil mixed at a ratio of

16:1 (8 oz. oil to 1 gallon gasoline).

4. DO NOT USE:

• NMMA Oil-- NationalMarine Manufacturers

Association (formerly BIA)

-- Does not have proper additives for 2-cycle, air-

cooled engines and can cause engine damage.

" AUTOMOTIVE OIL --

-- Does not have proper additives for 2-cycle, air-

cooled engines and can cause engine damage.

CAUTION

Experience indicates that alcohol blended fuels (called

gasohol or using ethanol or methanol) can attract

moisture which leads to separation and formation of

acids during storage. Acidic gas can damage the fuel

system of an engine while in storage. To avoid engine

problems, do not leave fuel in the unit when storing

for 30 days or longer. Start the engine and let it run

until the fuel lines and carburetor are empty. Use fresh

fuel next season. See the "Storage" section for addi-

tional information. Never use engine or carburetor

cleaner products in the fuel tank or permanent damage

can o(_cur.

5. HOW TO MIX FUEL AND FILL TANK

a. Pour 1/2 of the regular unleaded gasoline to be used

into an approved, marked container. Do not mix

gasoline and oil directly in the fuel tank.

b. Add entire measure of engine oil.

c. Cover container tightly and shake for one minute.

d. Slowly remove fuel container cover.

e. Add remainder of gasoline.

f. Cover container tightly and shake again.

g. Slowly remove fuel container cover.

h. Slowly remove fuel cap. See "Specifications" for

location.

i. Fill the tank using a spout or funnel.

j. Reinstall the fuel cap securely.
