FROM IGNITION. DO NOT START THE ENGINE NEAR SPILLED
FUEL.
NEVER USE GASOLINE AS A CLEANING AGENT.
WARNING: DO NOT OVERFILL THE FUEL TANK, LEAVE ROOM FOR
THE FUEL TO EXPAND.
GENERAL RECOMMENDATIONS
• Purchase gasoline in small quantities and store in clean, approved con-
tainers.
• To minimize gum deposits in your fuel system and to insure easy start-
ing, do not use gasoline left over from the previous season.
• Do not add oil to the gasoline.
FUEL TYPE
• For best results use only clean, fresh, unleaded gasoline with a pump
sticker octane rating of 87 or higher.
• Unleaded gasoline is recommended as it leaves less combustion cham-
ber deposits.
GASOLINE/ALCOHOL BLENDS:
Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is ap-
proved, as a fuel. Other gasoline/alcohol blends are not approved.
GASOLINE/ETHER BLENDS:
Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maxi-
mum of 15% MTBE by volume) are approved as a fuel. Other gasoline/ether
blends are not approved.

WARNING: SHOULD ONLY BE DONE BY AN AUTHORIZED DEALER.
HIGH ALTITUDE
At high altitude, the standard carburetor air/fuel mixture will be too rich. Per-
formance will decrease, and fuel consumption will increase. A very rich mixture
will also foul the spark plug and cause hard starting. Operation at an altitude
that differs from that at which this engine was certified, for extended periods of
time, may increase emissions.
High altitude performance can be improved by specific modifications to the
carburetor. If you always operate your generator at altitudes above 5,000 feet
(1,500 meters), have your dealer perform this carburetor modification. This en-
gine, when operated at high altitude with the carburetor modifications for high
altitude use, will meet each emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease about
3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude
on horsepower will be greater than this if no carburetor modification is made.
NOTE:When the carburetor has been modified for high altitude operation,
the air/fuel mixture will be too lean for low altitude use. Operation at al-
titudes below 5,000 feet (1,500 meters) with a modified carburetor may
cause the engine to overheat and result in serious engine damage.
For use at low altitudes, have your servicing dealer return the carbure-
tor to original factory specifications.
