GENERAL RECOMMENDATIONS
• Purchase gasoline in small quantities and store in clean, approved
containers.
• To minimize gum deposits in your fuel system and to insure easy
starting, 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
chamber deposits.
GASOLINE/ALCOHOL BLENDS:
Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is
approved, 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
maximum of 15% MTBE by volume) are approved as a fuel. Other gaso-
line/ether blends are not approved.
AC USAGE
Do NOT overload the generator. Exceeding the rated power of the gener-
ator can damage the generator and the electrical devices connected to it.
Motor-driven devices require a large starting current. Make sure that the
total power requirement of these types of loads does not exceed the
rated power of the generator.
When the generator is used to power multiple loads or electric applianc-
es, start by connecting the appliance with the highest starting power re-
quirements, followed by the second highest and ending with the lowest.
HIGH ALTITUDE
At high altitude, the standard carburetor air/fuel mixture will be too rich.
Performance will decrease, and fuel consumption will increase. A very
rich mixture will also foul the spark plug and cause hard starting. Opera-
tion 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
3,000 feet (900 meters), have your dealer perform this carburetor modi-
fication. This engine, when operated at high altitude with the carburetor
modifications for high altitude use, will meet each emission standard
throughout its useful life. If a carburetor is replaced, the proper high alti-
tude kit will need to be installed in the replacement carburetor.
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 altitudes below 3,000 feet (900 meters) with
a modified carburetor may cause the engine to overheat and
result in serious engine damage. At elevations above 8000 ft, the
engine may experience decreased performance, even with a high
altitude kit.
For use at low altitudes, have your servicing dealer return the car-
buretor to original factory specifications.
