Fuel must meet these requirements:
•
Clean, fresh, unleaded gasoline.
Use regular UNLEADED gasoline with the
generator engine with a minimum 87 octane
/ 87 AKI (91 RON).
For high altitude use, see "Operation at High
Altitude".
Do not use gasoline with more than 10%
alcohol such as E85 or ethanol.
•
•
Failure to follow Operator's Manual for fuel
recommendations voids warranty.
Avoid generator damage.
DO NOT use unapproved gasoline such as E85.
DO NOT mix oil in gasoline.
DO NOT modify engine to run on alternate fuels.

WARNING
Fuel and its vapors are extremely flammable
and explosive which could cause burns, fire or
explosion resulting in death, serious injury
and/or property damage.
WHEN ADDING FUEL
Fill fuel tank outdoors.
DO NOT overfill tank. Allow space for fuel
expansion. If the tank is overfilled, fuel
can overflow onto a hot engine and cause fire
or explosion. Wipe up any spilled fuel
immediately.
If fuel spills, wait until it evaporates before
starting engine.
Keep fuel away from sparks, open flames,
pilot lights, heat, and other ignition sources.
Check fuel lines, tank, cap and fittings
frequently for cracks or leaks. Replace if
necessary.
DO NOT light a cigarette or smoke when
filling the fuel tank.

•
1.Clean area around fuel fill cap, remove cap.
2.Slowly add unleaded fuel to fuel tank. Be
careful not to fill above the red fuel level
indicator . This allows adequate space for
fuel expansion.
3.Install fuel cap and let any spilled fuel
evaporate before starting engine or wipe up
any spilled gasoline.

CAUTION
Slowly add unleaded gasoline to fuel tank.
Do not overfill tank.

Do not fill above the red fuel level indicator.
This will allow expansion in hot weather and
prevent overflow.

High
Altitude
At altitudes over 5,000 feet(1524 meters), a
minimum 85 octane / 85 AKI (89 RON) gasoline
is acceptable.
The density of air at high altitude is lower than at
sea level. Engine power is reduced as the air mass
and air-fuel ratio decrease. Engine power and
generator output will be reduced approximately
3.5% for every 1000 feet of elevation above sea level.
This is a natural trend and cannot be changed by
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
" Long Term Storage" section. Never use engine
or carburetor cleaner products in the fuel tank
as permanent damage may occur.
