Caution: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and forma-
tion of acids during storage. Acidic gas can damage
the fuel system of an engine while in storage. To avoid
engine problems, the fuel system should be emptied
before storage for 30 days or longer. Drain the gas tank,
start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next season. See
Storage section of this manual for additional infor-
mation.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Never fill fuel tank indoors, when engine
is running or while engine is still hot.
Never fill fuel tank completely. Fill
tank to within 1/4 to 1/2 inch from the
top to provide space for expansion of
fuel. Wipe up any spilled fuel before
starting engine. Store gasoline in a
clean, approved container.
