OIL & FUEL RECOMMENDATIONS
TO OPERATE ENGINE, YOU WILL NEED THE FOLLOWING:
(_) A CLEAN, HIGH QUALITY, DETERGENT OIL.
Be sure original container is marked:
A.P.I. service "SF"-"SJ".
FOR SUMMER (ABO_;E 32°F;0°C) USE SAE 30 OIL.
Using multigrade oil will increase oil consumption.
FOR WINTER (BELOW 32°F;0°C) USE SAE 5W30 OIL.
(SAE 10W is an acceptable substitute.)

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 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.

IFENGINE ISTO 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.
_lb DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL.
DO NOT SMOKE.
B. Run engine until fuel tank is empty and engine stops due to
lack of fuel.
NOTE:
NOTE:
If "Gasohol" has been used, complete above
instructions and then put 1/2 pint of unleaded
gasoline into fuel tan k and repeat above instructions.
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 itto
reach carburetor,

GENERAL
Just as 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 agood 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.
