The DC terminals provide a power supply for DC power loads and charge other
batteries. The terminals are colored red to identify the positive ( +) terminal and
black to identify the negative (-) terminal. Load connection method: The load
must be connected to DC terminals with the proper polarity (load positive to
positive of DC terminal and load negative to negative of DC terminal).
High Altitude Operation
At high altitudes, a standard carburetor calibration will make the air-fuel
mixture too rich. This will reduce the output power and increase fuel consump-
tion. In addition, a rich mixture can foul the spark plug and cause hard starting
of the engine. Extended operation at an altitude that differs from the engine’s
calibration can also increase emissions. A carburetor modification can improve
high-altitude performance.
If you always operate the generator at high altitudes above 3300ft (1000m)
from sea level, you can take it to one of our authorized dealers to make that
adjustment. Even with the carburetor modification, engine horsepower will be
reduced, thus lowering the output rating of the generator. Every 1,000 ft (300m)
rise in altitude reduces the engine’s power by about 3.5%. This decline is even
more significant if the carburetor has not been appropriately adjusted.
Please note: If the carburetor has been modified for high-altitude operation,
the air-fuel mixture will be too lean for low altitude use. This can cause over-
heating and damage to the engine while being used at low altitudes. Return
the unit to your dealer to adjust the engine for low-altitude use.
