IF ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE,
PREPARE AS FOLLOWS:
QDRAIN 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.
lDO 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)
