NOTE: Fuel stabilizer (such as ULTRA-FRESH TM) is an acceptable
alternative inminimizing the formation ofgum 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.
CHANGE OIL:
Change oil if it has not been changed in the last three (3) months. See
"CHANGE OIL" instructions in "MAINTENANCE" section.
(_ OIL CYLINDER BORE:
A. Remove spark plug. Squirt one (1) oz. (30 ml) of clean engine oil into

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,
