
After the engine starts up, warm up it under unload for approx. five minutes.

Warming up after starting up is necessary for smooth operation of the engine. Do not operate the engine
at full load immediately after it starts up. This will shorten the equipment life.

During the warm-up operation, examine the different parts of the equipment for any looseness, leakage
of water, oil, fuel, and other irregularities.

Also, make sure that the alarm lamps are off.

Be sure to operate the generator at a rated frequency, irrespective of the load capacity.
If the machine is operated with a frequency lower than the rated frequency, it could cause the generator
main unit or to be burned.
