High altitude operation
At higher altitudes, the standard carburetor air-fuel mixture will be excessively rich.
Performance will decrease, and fuel consumption will increase. Power output will
decrease 3.5% for each 1000 feet (305 meters) above sea level.
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 or 1500 meters above sea level, have your authorized dealer install a high
altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately
3.5% for each 1000 feet or 305 meter increase in altitude. The affect of altitude on
the horsepower will be greater than this if no carburetor modification is made.
■
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.
■
Be sure to have any modification reversed at lower altitudes.
Temperature
High temperature adversely 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)
