A. FUELING YOUR ENGINE
1.FUEL SAFETY
a.Useonly recommended fud mixtures.
b. Mix and pour fuel ouldoors and where there are
nosparksor flames.
c. Use a container approved for fud.
d. Do not smoke or allow smoking near fuelor the tool
or while using the tool.
e. Wipe up all furl spills before starting the engine_
f. Move at least 10 feet away from furling site
before starting engine.
g. Stop engine before-removing fuel calx Allow
the engine to cool before refueling.
h. Before storing toot; use up fad left in carbm_
lor by starting engiffe and letting 'it run until it
stops.
i. Store tool and fuel in an area where fuel vapors
cannot reach sparks or olden flames from water
heaters, eloctdc motors or switches, furnaces, etc.
. FUEL MAXTIJRE
Your tool is powered by a 2-cycle engine which
requires a furl _ of regular unleaded gaso- line and a high qu_ity engine oil specially made for 2-¢ycle_ air cooled engines. The internal design oftbe 2-c-ycle engine requires lubrication of moving parts. I__brication is provided when the reoommended mixture ofgasol ine and oil
is used.
Genuine Sears40:l, 2-cycle engine oil is str_ recommended for the protection,of your unit. Exte_iveengineeiingtestshavepi_veathat Sears
-2-cycle erigine o'flresists brzak-downa_-operatlng
in d_le l_rforulanc_ and longer engine life.
Gasoline must bedean and not over two months old. Aftera short period of time, gasolin_willchem- ically break down and form compounds thaf_ause
hard starting _ damage in 2-cycle engines.
s The correct measure of gasoline to Oil is very
important. Too much oil in the mixtu_ will foul the spark plug.
ICAUrloN:] Too little oH or incorrect 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 stronglyrecommended. Con- suit the in.structions on the oil container for
Rroper nnxmg.
1 PART OIL TO 40 PARTS GASOLINE=
3.2 ft. oz. oil to I gallon gasoline
8.0 ft. oz. off to 2.5 gallon gasoline
Not all air cooled 2-cycle engine oils ha_'e the same qualities. If SEARS CRAFTSMAN 2-cycle
engine oil is not available, use a good quality,
2-cycle engine oil recommended for air-cooled engines. Mix at a ratio of 40: I (3.2 oz. oil to i
gallon gasoline).
4.DO N0T USE:
" NMMA Oil-- National Ma'-ine Manufacturers
Association (formerly BIA)
-- Does not have proper additives for 2-cycle, air- cooled engines and can cause engine damage.
- AUTOM{H_rE OIL__
-- Does not have proper additives for 2-cycle, air-

NOTE: ff you do not want to remove the fuel from your unit, SEARS CRAFTSMAN Fuel Stabilizer (#'/1-33500) may be added to fuel left in the tank to
minimize gum deposits and acids. If the tank is almost empty, mix stabilizer with fresh fuel ina_parate con-
tainer and add to the taidc.
.5. HOW TO MIX FUEL AND FILL TANK
:<_ Do, nOi__Taixgasoline and oil directly in
the fuel tank.
a. Pour the proper measure of engine oil into an
approved, marked fuel containei'. Then, fill the container with regular unleaded gasoline.
If fuel is already in the container, add the proper measure of engine oil. Then, close the container tightly and shake it momentarily.
b. Slowly remove fuel cap. c. Using a spout or funnel, fill the. fuel tank with
fuel mix.
d. Reinstall the fuel caps securely.
