FUELING YOUR ENGINE

A. FUELING INFORMATION

1. FUEL SAFETY

a. Use only recommended fuel mixtures.

b. Mix and pour fuel outdoors and where

there are no sparks or flames.

c. Use a container approved for fuel,

d. Do not smoke or allow smoking near fuel

or the unit or while using the unit.

e. Wipe up all fuel spills before starting the

engine

fi Move at least 10 feet away from fueling

site before starting engine.

g. Stop engine before removing fuel cap

h. Before storing the unit, use up fuel left in

the fuel lines and carburetor by starting the

engine and letting it run until it stops.

i. Store unit and fuel in an area where fuel

vapors cannot reach sparks or open

flames from water heaters, electric motors or

switches, furnaces, etc.

j. Always remove the fuel cap slowly to re-

lieve pressure in the fuel tank.

2. FUEL MIXTURE

®Your unit is powered by a 2-cycle engine

which requires a fuel mixture of regular

unleaded gasoline and a high quality en-

gine 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 recom-

mended mixture of gasoline and oil is used_

eGasoline must be clean and fresh, After a

short period of time, gasoline will chemically

break down and form compounds that cause

hard starting and damage in 2-cycle engines_

e The correct measure of gasoline to oil is

very important. Too much oil in the mixture

will foul the spark plug,

Too little oil will cause the engine

to overheat and seize.

3. USE THE FOLLOWING ONLY:

SEARS CRAFTSMAN 2-cycle engine oil

mixed at 40:1 is strongly recommended, Con-

sult the instructions on the oil container for

proper mixing.

1 PART OIL TO 40 PARTS GASOLINE=

3,2 fl oz, oil to igallon gasoline

8.0 fl, oz. oil to 2.5 gallon gasoline

Not all air cooled 2-cycle engine oils have the

same qualities, If SEARS CRAFTSMAN

2-cycle engine oil is not available, use agood

quality, 2-cycle engine oil recommended for

air - cooled engines, Mix at a ratio of 16:1 (8 oz,

oil to 1 gallon gasoline)_ A 16:1 fuel mixture

with these oils will assure adequate lubrication

for your engine,

4. DO NOT USE:

eNMMA Oil--National Marine Manufac-

turers Association (formerly BIA)

Does not have proper additives for air-cooled,

2-cycle engines and can cause engine damage

e AUTOMOTIVE OIL-

Does not have proper additives for air- cooled,

2-cycle engines and can cause engine damage.

ACAUTION

Experience indicates that alcohol blended fuels

(called gasohol or usingethanol or methanol) can

attract mmsture which leads to separation and

formation of acids during storage. Acidic gas can

damage the .ft_el system of an engine while in stor.

age. To avmd engine problems, do not leave fuel

mthe umt 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 sea-

son. See the "Storage" sectmn for additional in-

formation. Never use engine or carburetor clean-

er products in the fuel tank or permanent damage

can occur.

5. HOW TO MIX FUEL AND FILL TANK

a_ Pour the proper measure of engine oiI into an ap-

proved, marked container Then, fill the con-

talner with regular unleaded gasoline,

NOTE: If fuel is already in the container, add the

proper measure of engine oil Then, close the

container tightly and shake it momentarily.

NOTE. Do not mix gasoline and oil directly in the

fuel tank.

b, Using a spout or funnel, fill the fuel tank with

fuel mix.

c Reinstall the fuel caps securel_

C. FUEL TANK

1. Never use gasoline that is more than 2

months old in a fuel mixture. Gasoline begins

to break down after a short period of time and will

form compounds that cause hard starting and

damage in 2-cycle engines.

Using a fuel mix or gasoline over 2

months old will cause the engine to be diffi-

cult or impossible to start.

2_ Inspect the unit for fuel leaks each time it is

used. Repair or replace parts as necessary.

3. Do not leave fuel in the unit when storing

for 30 days or longer. Use up fuel left hz the fuel

lines and carburetor by starting the engine and

letting it run until it stops,

D. STORAGE

1. Clean the unit before storing. Pay particular

attention to the air intake area, keeping it free of

debris. Use a mild detergent and sponge to clean

the plastic surfaces.

2. Do not store the unit or fuel in a closed area

where fuel vapors can reach sparks or an open

flame from hot water heaters, electric motors or

switches, furnaces, etc.

3. Store unit in a dry area out of the reach of

children.

4. Do not leave fuel in the unit when storing

for 30 days or longer. Use up fuel left in the fuel

lines and carburetor by starting the engine and

letting it run until it stops.

NOTE: If you do not want to remove the gasolhm

from your unit, SEARS CRAFTSMAN Fuel Stabi-

lizer (#71 - 33500) may be added to gasoline left in

the tank to minimize gum deposits and acids. If

the tank is almost empty, mix stabilizer with fresh

gasoline in a separate container and add to tank.

ALWAYS FOLLOW INSTRUCTIONS ON THE

STABILIZER CONTAINER. THEN, RUN THE

ENGINE AT LEAST 2 MINUTES AFTER STA-

BILIZER IS ADDED TO ALLOW MIXTURE TO

REACH CARBURETOR. STORE UNIT IN A

SAFE PLACE. SEE STEP 2 (this section).

Ak WARNING

It is important to prevent gmn deposits frog

forming in essential fuel system parts such as th_

carburetor, fuel filter, fuel hose, or fuel tank dur

ing storage. 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 en-

gine while in storage.
