Operation Manual

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 and readjusting the pilot screws. If you always operate
the generator at altitudes higher than 1,500 m (5,000 feel) above sea level, have
your authorized dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease
approximately 3.5% for each 305m (1,000 feet increase in altitude. The affect of
altitude on the horsepower will be greater than this if no carburetor modification
is made.
CAUTION
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.
5. USE
WARNING:
■ To prevent electrical shock from faulty appliances, the generator should be
grounded.Connect a length of heavy wire between the generator's ground
terminal and an external ground source.
■ Connections for standby power to a building's electrical system must be
made by a qualified electrician and must comply with all applicable laws and
electrical codes. Improper connections can allow electrical current from the
generator to backfeed into the utility lines. Such backfeed may electrocute
utility company workers or others who contact the lines during a power
outage, and when utility power is restored. the generator may explode, burn,
or cause fires in the building's electrical system.
