Environmental Impacts on Generator Performance
Environmental conditions, such as high altitude and extreme temperatures, adversely impact the generator’s
performance. When environmental conditions are combined in any way, performance issues are compounded.
In other words, running the generator in an extreme temperature comes with its own considerations, but if you are
also at a high altitude any performance issues are multiplied and increasingly difficult to overcome.

High Altitude Every 1000 ft. (305m) increase in altitude 3.5% decrease in engine horsepower
High Temperature Every 10°F (5.5°C) increase in temperature above 85°F

1% decrease in engine horsepower
High Altitudes
At high altitude, the air-fuel mixture will be excessively rich, performance will decrease, and fuel consumption
will increase. The generator uses an Engine Control Unit (ECU) to maintain the proper air-fuel mixture. The ECU
automatically compensates to ensure the maximum possible performance at high altitudes.
Extreme Temperatures
The normal operating range of this generator is 0° to 113°F (-18° to 45°C). Outside of this range, extreme
temperatures adversely affect generator startup and operation.
▲ Do not operate the generator when the ambient temperature is below 0°F (-18°C).
▲ Do not operate the generator when the ambient temperature is above 113°F (45° C).
High Temperatures
In extremely high temperatures, the performance of the generator decreases 1% for each 10°F (5.5°C) increase in
temperature above 85°F (29°C).
Cold Temperatures
In extremely cold temperatures, the engine will be more difficult to start. To operate the generator in very cold
climates, it is important to have a fully charged battery and use a lower viscosity engine oil.
Oil Viscosity for Cold Climates
Synthetic SAE 0W-30 or 0W-40 oil is recommended for temperatures below 32° F. Refer to the chart below for oil
viscosity recommendations.
Because you need to use a low viscosity oil in extremely cold climates, the engine will actually take longer than
normal to warm up due to reduced internal friction.
