Fuel

Explosion and Fire. Fuel and vapors are
extremely flammable and explosive. Add fuel
in a well ventilated area. Keep fire and spark
away. Failure to do so will result in death
or serious injury.
Do not overfill fuel tank. Fill to 1/2 in. of top of tank to
allow for fuel expansion. Overfilling may cause fuel to
spill onto engine causing fire or explosion, which will
result in death or serious injury.
Fuel requirements are as follows:
• Clean, fresh, unleaded gasoline.
• Minimum rating of 87 octane/87 AKI (91
RON).
• Up to 10% ethanol (gasohol) is acceptable.
• DO NOT use E85.
• DO NOT use a gas oil mix.
• DO NOT modify engine to run on alternate
fuels. Stabilize fuel prior to storage.
1. Verify unit is OFF and cooled entirely prior
to fueling.
2. Place unit on level ground in a well venti-
lated area.

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 before storage of 30
days or longer. See the
Never use engine or carburetor cleaner
products in the fuel tank as permanent
damage may occur.
