At high altitude, the standard carburetor air-fuel mixture
will be too rich. Performance will decrease and fuel
consumption will increase. A very rich mixture will also foul
the spark plug and cause hard starting. Operation at an
altitude that differs from that at which this engine was
certified, for extended periods of time, may increase
emissions.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your
engine at altitudes above 1,829 meters (6,000 feet), have your
authorized service center perform a carburetor modification.
Even with a carburetor modification, engine horsepower
will decrease about 3.5% for each 300 meter (1,000 foot)
increase in altitude. The effect of altitude on horsepower will
be greater if no carburetor modification is made. A decrease
in engine horsepower will decrease the power output of the
generator.
NOTICE:
Warranty is Void if the necessary adjustments for
high altitude use are not made.
PRE-START PREPARATION
Before starting the generator, check for loose or missing
parts and for any damage which may have occurred during
shipment.
STARTING THE ENGINE
1. Check oil level and fuel.
2. Disconnect all electrical loads from the unit.
3. Open fuel shut off valve (A).
4. Adjust choke (B) as necessary.
5. Set the engine switch (C) to the “ON" position.
6. Pull on the starter rope (D) with fast steady pull. As the
engine warms up, readjust the choke.
STARTING THE UNIT
STARTING THE UNIT
Gasoline is very dangerous.
Serious injury or death may result from fire caused by
gasoline contacting hot surfaces.
1. Do not fill fuel tank with engine running.
2. Do not spill fuel while refilling tank.
3. Do not mix oil with gasoline.
4. Follow all instructions and warnings in the operator
manual.
This generator must not be operated without all factory
installed heat shields in place. Failure to comply may cause
the fuel tank to overheat and result in personal injury from
fire.
Allow generator to run at no load for five minutes upon each
initial start-up to permit engine and generator to stabilize.

HIGH ALTITUDE OPERATION
HIGH ALTITUDE OPERATION
When the carburetor has been modified for high
altitude operation, the air-fuel mixture will be too lean
for low altitude use. If the generator is used at low
altitudes after a carburetor modification, the
carburetor may cause the engine to overheat and result
in serious engine damage. For use at low altitudes,
have your authorized service center return the
carburetor to original factory specifications.
