With Smart Throttle in OFF position -
Smart Throttle system does not operate and engine speed varies with the load.
High Altitude Operation -
At higher altitudes, the standard carburettor air-fuel mixture will be excessively rich. Performance
will decrease, and fuel consumption will increase. Power output will decrease 3.5% for each 300m
(1000 feet) above sea level.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the
carburettor. If you always operate the generator at altitudes higher than 1500m (5000 feet) above
sea level, have your authorised dealer install a high altitude main jet.
Even with suitable carburettor jetting, engine horsepower will decrease approximately 3.5% for
each 300m (1000 feet) in increased altitude. The affect of altitude on the reduction of horsepower
will be greater if no carburettor modification is made.
• Operation of the generator at an altitude lower than the carburettor is jetted, 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 unfavourably affects generator operation. Generator performance will decrease
1% for each 5.5°C (10°F) increase in temperature above 29°C (85°F).
The normal operating range of this generator is -29° to 45°C (-20° to 113°F).
• Do not operate the generator when the ambient temperature is below -29°C ( -20°F).
• Do not operate the generator when the ambient temperature exceeds 45°C (113°F).
