AND CONDITIONS. IF ADJUSTMENTS ARE NEEDED,
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 shouldnot be affected
at altitudes up to 7,000 feet. For operation at higher elevations,
contact your nearest SEARS, ROEBUCK AND CO. (OR SEARS

IF ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE,
PREPARE AS FOLLOWS:
Q
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.
_IL DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL.
l 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
infuel tank or storage container. Always follow mix
ratio found on stabilizer container. Run engine at
least 10 minutes after adding stabilizer to allow itto
reach carburetor,
_) CHANGE OIL:
Change oil if it has not been changed in the last three (3)
months, See =CHANGE OIL" instructionsin "MAINTENANCE"
sectionon 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 tim¢_,

CRANKING ENGINE OVER SLOWLY,
O. Replace spark plug.
(_ CLEAN ENGINE:
Remove any clippings, dirt, or chaff from exterior of engine.
GENERAL
Justas your 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.
