OPERATING SPEED
The generator must be run at the correct speed in order to produce the proper electrical voltage and frequency. The speed of the engine was carefully adjusted at the factory so that the generator produces the proper voltage and frequency.
The output voltage should be checked to ensure the generator is working properly before connecting a load to the generator. Failure to do so could result in damage to equipment plugged into the unit and possible injury to the individual.
All engines have a tendency to slow down when a load is applied. When the electrical load is connected to the generator, the engine is more heavily loaded, and as a result the speed drops slightly. This slight decrease in speed, together with the voltage drop within the generator itself, results in a slightly lower voltage when the generator is loaded to its full capacity than when it is running with no load. The slight variation has no appreciable effect in the operation of motors, lights and most appliances. Electronic equipment and clocks will be affected if correct RPM is not maintained. See Load vs. Output chart.

Output voltage should be checked periodically to ensure continued proper operation of the generating plant and appliances. It can be checked with a portable meter. Frequency can be checked by using an electric clock with a sweep second hand. Timed against a wristwatch or a stopwatch, the clock should be correct within +/- 2 seconds per minute. All speed setting adjustments should be done by a qualified technician.
BEFORE STARTING
1.Make sure the generator is positioned on firm level surface.
2.Check the crankcase for oil and maintain at a proper level.
3.Check fuel level and fill tank 7/8 full with fresh unleaded automotive gasoline. Never fill fuel tank completely to the top. Always wipe up and remove any spilled gasoline.
4.Make sure that the exhaust fumes are directed away from people.
STARTING - MANUAL
1.Disconnect all loads to generator.
2.Turn gas line valve to ON position.
3.Turn key to the ON position.
4.For cold engine, move choke lever to full choke
position, for warm engine, move choke lever to half choke or to RUN position.
5.Firmly grasp recoil handle and pull.
6.When engine starts, move choke lever to RUN
position.
7. Loads may now be connected to generator.
STARTING - ELECTRIC
1.Disconnect all loads to generator.
2.Turn gas line valve to ON position.
3.For cold engine, move choke lever to full choke position, for warm engine, move choke lever to half choke or to RUN position.
4.Turn key to start position.
5.When engine starts, move choke lever to RUN position.
6.Loads may now be connected to generator.
STOPPING
1.Disconnect all loads to generator.
2.Turn engine key switch to OFF position.
3.Turn gas line valve to OFF position.
ENGINE CARE
Refer to your Engine Owner’s Manual for proper care and maintenance.
NOTE: When changing the oil on a hot engine, the oil might overshoot the oil drain hole on the generator base. Use a deflector (piece of cardboard or paper) to direct the oil down the hole.
