PROCEED AS FOLLOWS:
(_ CARBURETOR
If you think your carburetor needs adjusting, see your nearest
SEARS, ROEBUCK AND CO. (OR SEARS CANADA, INC.)
SERVICE CENTER. Engine performance should not be affected
at altitudes up to 7,000 feet. For operation at higher elevations,
contact your nearest SEARS, ROEBUCK AND CO. (OR SEARS
CANADA, INC.) SERVICE CENTER.
(_) ENGINE SPEED
NEVER TAMPER WITH ENGINE GOVERNOR WHICH IS
FACTORY SET FOR PROPER ENGINE SPEED.
OVERSPEEDING ENGINE ABOVE FACTORY HIGH SPEED
SETTING CAN BE DANGEROUS.
CHANGING OF ENGINE-GOVERNED SPEED WILL VOID

FUEL FUMES MAY REACH AN OPEN FLAME, SPARK OR
PILOT LIGHT AS ON A FURNACE, WATER HEATER,
CLOTHES DRYER OR OTHER GAS APPLIANCE.
IF ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE,
PREPARE AS FOLLOWS:
(_ DRAIN FUEL SYSTEM:
A. Remove all gasoline from carburetor and fuel tank to
prevent gum deposits from forming on these parts and
causing possible malfunction of engine.
,_ DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL.
I DO NOT SMOKE.
B. Run engine until fuel tank is empty and engine stops due
to lack of fuel.
NOTE: If "Gasohol" has been used, complete above
instructions and then put 1/2 pint of unleaded
gasoline into fuel tank and repeat above
instructions.
NOTE:
Fuel stabilizer (such as STA-BIL) is an acceptable
alternative in minimizing the formation of fuel gum
deposits during storage, Add stabilizer to gasoline
in fuel tank or storage container. Always follow mix
ratio found on stabilizer container. Run engine at
least 10 minutes after adding stabilizer to allow it to
reach carburetor.
CHANGE OIL:
Change oil if it has not been changed in the last three (3)
months. See "CHANGE OIL" instructions in "MAINTENANCE"
section on Page 3.
(_) OIL CYLINDER BORE:
A. Remove spark plug and pour one (1) ounce (30 ml) of
engine oil into spark plug hole.
B. Cover spark plug hole with a rag.
C. Crank engine over, slowly, several times.
,_ AVOID SPRAY FROM SPARK PLUG HOLE WHEN
CRANKING ENGINE OVER SLOWLY,
D. Replace spark plug.
@ CLEAN ENGINE:
Remove any clippings, dirt, or chaff from exterior of engine.

GENERAL
Just asyour automobile needs professional mechanical maintenance
from time to time, so does your Craftsman engine. Replacement of
the spark plug and air cleaner is made necessary by NORMAL use.
Professional Air-Cooled Engine Service is as close as your nearest
Sears Roebuck and Co. (or Sears Canada, Inc.) Service Center.
A yearly check-up or tune-up by Sears is a good idea to avoid
breakdowns or delay.., do it at the end of the season, then you're
ready for the next. We even prepare it for storage for you.
