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 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 effect of altitude on
the horsepower will be greater than this if no carburetor modification is made.
n 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)
n Do not operate the generator when the ambient temperature is below -20°F
(-29°C).
n Do not operate the generator when the ambient temperature exceeds 113°F
(45°C).
6. Stopping The Engine
2. Turn the engine switch to the OFF position.
To stop the engine in an emergency, turn the engine switch to the OFF position.
IN NORMAL USE:
1. Switch off the connected equipment and pull the inserted plug out.
