High altitude operation
At high altitude, the standard carburetor air-fuel mixture will be excessively rich.
Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the
carburetor. If you always operate the generator at altitudes higher than 5000 feet (1500 m) above
sea level, have your authorized dealer install the high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for
each 1000' (305 m) increase in altitude. The affect of altitude on the horsepower will be greater if
no carburetor modification is made.
Temperature
High temperature unfavorably affects generator operation. Generator performance will decrease
1% for each 10°F (5.5° C) increase in temperature above 85°F (29°C). The normal operating
range of this generator is -20° to 113° F (-29° to 45° C)
■ Do not operate the generator when the ambient temperature is below -20° F (-29° C)
■ Do not operate the generator when the ambient temperature exceeds 113°F (45° C)
■Operation of the generator at an altitude lower than the carburetor is
jetted for may result in reduced performance, overheating, and
serious engine damage caused by an excessively lean air/fuel
mixture.
