High Altitude Operation from 1640 feet to 7000 feet
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.
The fuel system on this Engine or Equipment may be influenced by operation at higher altitudes. It must
install an altitude kit at altitudes from 1640ft. to 7000ft. above sea level. Kits should be installed by a
qualified individual.
WARNING: To prevent serious injury from fire: Follow the kit procedures in a well-ventilated
area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it
to cool before proceeding.
NOTICE: The warranty may be void if necessary adjustments are not made for high altitude use.
NOTICE:
Even with carburetor modification, engine horsepower will decrease in high altitude. The
effect of altitude on horsepower will be greater than this if no carburetor modification is made.
STARTING THE ENGINE
OFF
ON
4. Open the Fuel Valve.(See Picture 1)
To start the generator, perform the following steps:
1. Unplug all electrical devices from the generator during ignition. Otherwise it
will be difficult for the engine to start.
2. Check that the generator is properly grounded (Refer to “GROUND THE
GENERATOR”).
3. Check the oil and fuel levels.

5. To start a cold engine, move the Choke to the START position.
To restart a warm engine, leave the Choke in the RUN position.(See Picture 2)

7. Grip the Starter Handle of the Engine loosely and pull it slowly
several times to allow the gasoline to flow into the Engine’s carburetor.
Then pull the Starter Handle gently until resistance is felt. Allow Cable
to retract fully and then pull it quickly. Repeat until the engine starts.(See Picture 4)
Note: Do not let the Starter Handle snap back against the engine.Hold it as
it recoils so it doesn't hit the engine.
IMPORTANT: If engine fails to start, repeat step 7. NOTE: After repeated
failed attempts to start the engine, please consult the troubleshooting guide
before attempting again.
8. Allow the Engine to run for several seconds. Then, if the Choke lever is in
the START position, move the Choke Lever very slowly to its RUN position.(See Picture 5)
Note: Moving the Choke Lever too fast could stall the engine.
IMPORTANT: Allow the engine to run at no load for five minutes after each
start-up so that the engine can stabilize.
Break-in Period:
a. Breaking-in the engine will help to ensure proper equipment and engine operation.
b. The break-in period will last about 25 hours of use.DO NOT exceed 75% of the
Generator’s rated capacity during this period.
•Change the engine fuel/oil mixture after this period.Under normal operating
conditions subsequent maintenance follows the schedule explained in the
Maintenance section.
START RUN
6. Turn the Engine Switch on.(See Picture 3)
