High Altitude Operation; Ambient Temperature - Kipor IG3000 Owner's Manual

4.1(e) Push the choke knob in to the OPEN position as the engine warms up.

4.2 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 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 effect of altitude on the horsepower will be greater
than this if no carburetor modification is made.

4.3 Ambient Temperature

Generator output generally derates 1% for every 10° F (5.5° C) above 85° F (29° C). The normal
operating range of the generator is -20° to 113° F (-29° to 45° C).

■Operation of the generator at an altitude lower than the carburetor is
jetted for may result in reduced
serious engine damage caused by an excessively lean air/fuel
mixture. Be sure to have any modification reversed at lower altitudes.
■Do not operate the generator when the ambient temperature is below
-20° F (-29°)
■Do not operate the generator when the ambient temperature is above
113° F (45° C)
