HIGH ALTITUDES
At higher altitudes, 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 6000 feet
(1800 m) 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 (305 m)
increase in altitude. The effect of altitude on the horsepower
will be greater than this if no carburetor modification is made.
!
WARNING: Be sure to have any carburetor modification
reversed before operating at lower altitudes. 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.
OPERATING AT EXTREME TEMPERATURES
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 0°C to 45°C
(Up to 113° F). Although the generator can operate in colder
climates, it will be necessary to use a lower viscosity engine
oil. Refer to the chart below for recommendations based on
temperature ranges.
!
NOTE: In very cold weather the engine will actually take
longer than normal to warm up because the oil is thinner
and there is less internal friction throughout the warm up
period.
!
CAUTION: Do not operate the generator when the
ambient temperature is below 0°C. Do not operate the
generator when the ambient temperature is above 45°C
(113°F)
