Explosion and Fire. Verify fuel cap vent is set to
ON for operation, and OFF for transportation and
storage. Failure to do so could result in poor unit
performance, death, or serious injury.
3. Clean area around fuel cap.
4. Turn cap slowly to remove.
5. Slowly add recommended fuel. Do not
overfill.
6. Install fuel cap.
NOTE: Allow spilled fuel to evaporate before
starting unit.
IMPORTANT NOTE: It is important to pre-
vent gum deposits from forming in fuel
system parts such as the carburetor, fuel
hose or tank during storage. Alcohol-
blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which
leads to separation and formation 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 or treated before stor-
age of 30 days or longer. See the
section. Never use engine or carburetor
cleaner products in the fuel tank as perma-
nent damage may occur.
