1. Disconnect all electrical loads from the generator and place the main circuit breaker in the off (open)
position.
2. Turn the idle control switch (Fig.10-H) off.
3. Open the fuel valve by turning the petcock clockwise to the vertical position as shown in Fig.12.
4. If the engine is cold, pull the choke lever out to the closed position shown in Fig.13. If the engine is hot, set
choke to open position shown in Fig.14.
5. Turn engine switch (Fig.10-A) on.
6. Pull the starter grip slowly until you feel compression then pull briskly.
NOTE: Do not allow the starter grip to snap back. Return it slowly by hand.
NOTE: If the oil level in the engine is low, the engine will not start. If the engine does not start, check the oil
level and add oil as needed.
NOTE: To ensure maximum oil lubrication, place the generator on a level surface.
7. As the engine warms up, move the choke lever to the open position shown in Fig.14.
8. Allow the engine to warm up for a few minutes. Then place the main breaker (Fig.10-B) in the on (closed)
position. Attach electrical loads.
STOPPING THE GENERATOR
To stop the engine in an emergency, move the engine switch to the off position.
To stop the generator in normal use:
1. Turn off and disconnect all electrical loads attached to the generator.
2. Turn the engine switch off.
3. Close the fuel valve by turning petcock counterclockwise to the horizontal
position shown in Fig.12.
ENGINE SPEED
Generators require a fixed engine speed to maintain the
correct voltage. Engine speed is controlled by the governor
which automatically adjusts to varying loads on the engine to
maintain a constant speed of 3600-3700 r/min.
NOTE: Do not adjust the governor setting of this generator.
It has been set at the factory for optimum performance.
Tampering may cause damage to the generator and voids the
warranty. The governor may only be adjusted by an authorized
service center.

HIGH ALTITUDE OPERATING
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.
High altitude performance can be improved by specific modifications to the carburetor. If you
always operate your engine at altitudes above 6,000 feet (1,800 meters), have your authorized
service center perform a carburetor modification.
Even with a carburetor modification, engine horsepower will decrease about 3.5% for each
1,000 feet (300 meters) increase in altitude. The effect of altitude on horsepower will be greater
than this if no carburetor modification is made. A decrease in engine horsepower will decrease
the power output of the generator.
NOTE: 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.
