fected at altitudes up to 7,000 feet. For operation at higher

elevations, contact your nearest SEARS, ROEBUCK AND CO.

of fuel.

tions 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.

GENERAL

Just as your automobile needs professional mechanical mainte

nance from time to time, so does your Craftsman engine. Replace

ment 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, I nc.) 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.
