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 hzthe 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.
