CONSUMER MAINTENANCE SCHEDULE
FUEL RECOMMENDATIONS
Before each use, check the fuel tank gauge. If the fuel
level is low, refill the tank with recommended fuel. NEVER
OVERFILL.
General Fuel Information
Check the fuel gauge located on the top of the generator
near the fuel tank and refill the tank if fuel level is low.
Refuel carefully to avoid spilling fuel. Do not fill above the
shoulder of fuel strainer. Use unleaded gasoline with a
pump octane rating of 87 or higher.
Never use stale or contaminated gasoline. Avoid getting
dirt or water in the fuel tank. Always keep the fuel strainer
in place while refueling.
Oxygenated Fuels
At certain times of the year, some U.S. locations may have
only oxygenated fuel available. Oxygenated fuel is
blended with alcohol or ether additives to increase octane
quality, enhance combustion, and reduce exhaust emis-
sions.
Some areas of the United States use oxygenated fuels to
help meet clean air standards.
Before using an oxygenated fuel:
•
Be sure pump octane rating is 87 or higher.
•
Try to confirm contents of fuel.
Some states (and provinces in Canada) require this infor-
mation to be posted on the fuel pump. If you notice unde-
sirable operating symptoms, switch to a conventional
unleaded gasoline.
Fuel and fuel vapors are extremely flammable and
explosive under certain conditions.
• Refuel generator only outdoors, in a well-ventilated
area.
• NEVER fill fuel tank while engine is running. Turn gen-
erator OFF and allow to cool before filling with fuel.
• NEVER smoke or allow flames or sparks near genera-
tor or where gasoline is stored.
• NEVER overfill fuel tank (no fuel should be in filler
neck). After refueling, be sure fuel tank cap is closed
properly and securely.
• Be careful not to spill fuel when refueling. Spilled fuel
or fuel vapor may ignite. If any fuel is spilled, be sure
area is dry before starting engine.
• Avoid repeated or prolonged contact with skin or
breathing of vapor.
NOTICE
Oxygenated fuels can damage paint and plastic. Be careful
not to spill fuel when filling fuel tank. Damage caused by
spilled fuel is not covered under warranty.
TABLE 7-2.
Oxygenated Fuel Types
Ethanol
(ethyl or grain alcohol)
Gasoline containing more
than 10% ethanol by volume
may cause starting or perfor-
mance problems. Gasoline
containing ethanol may be
marketed under the name
"Gasohol".
Methanol
(methyl or wood alco-
hol)
Gasoline containing metha-
nol must contain co-solvents
and corrosion inhibitors to
protect fuel system. Gasoline
containing more than 5%
methanol by volume may
cause starting and/or perfor-
mance problems and may
damage metal, rubber and
plastic parts of fuel system.
MTBE
(methyl tertiary butyl
ether)
Gasoline containing up to
15% MTBE by volume can
be used.
NOTICE
To avoid damage to the engine, never use stale or contami-
nated gasoline or oil/gasoline mixture. Avoid getting dirt or
water in the fuel tank.
Use fresh gasoline with a pump octane rating of 87 or
higher.
NOTICE
Running the engine with persistent spark knock or pinging
can cause engine damage. Warranty does not cover parts
damaged by misuse.
