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.
Explosion and Fire. Do not overfill fuel tank. Fill to
1/2 inch from 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
(where available; non-ethanol fuel is rec-
ommended).
• 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 for a mini-
mum of two minutes prior to fueling.
2. Place unit on level ground in a well venti-
lated area.
3. Clean area around fuel cap and remove
cap slowly.
4. See 2-16. Slowly add recom-

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 fuel injectors,
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
Owner's Manual for Portable Generator

section.
Storage
Never use engine or carburetor cleaner
