2.7.2 ADDING GASOLINE

Never fill fuel tank indoors. Never fill fuel tank

when engine is running or hot. Avoid spilling
gasoline on a hot engine. Allow engine to cool
entirely before filling fuel tank.

Do not overfill the fuel tank. Always leave room

for fuel expansion. If the fuel tank is overfilled,
fuel can overflow onto a hot engine and cause
FIRE or EXPLOSION. Wipe up any spilled fuel
immediately.

Do not light a cigarette or smoke when filling

the fuel tank. Gasoline is highly FLAMMABLE
and its vapors are EXPLOSIVE.
• Use regular UNLEADED gasoline with the generator engine. Do
not use premium gasoline. Do not mix oil with gasoline.
• Do not use gasoline with more than 10% alcohol such as E85
or Methanol.
• Clean area around fuel fill cap, remove cap.
• Slowly add unleaded regular gasoline to fuel tank. Fill to bottom
of screen filter. Be careful not to overfill (Figure 9).
• Install fuel cap and wipe up any spilled gasoline.

IMPORTANT: It is important to prevent 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 "Storage" section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage may
occur.
