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.
CAUTION:
■
Limit operation requiring maximum power to 30 minutes. For continuous
operation, do not exceed the rated power. In either case, the total wattage of
all appliances connected must be considered.
■
Do not exceed the current limit specified for any one receptacle.
■
Do not connect the generator to a household circuit. This could cause the
damage to the generator or to electrical appliances in the house.
■
Do not modify or use the generator for other purposes than it is intended for.
Also observe the following when using the generator.
- Do not connect generators in parallel.
- Do not connect an extension to the exhaust pipe.
■
When an extension cable is required, be sure to use a tough rubber
sheathed flexible cable.
■
Limit length of extension cables; 60 m for cables if 1.5 mm² and 100 m for
cabes of 2.5 mm².
