4.4 Unit Operation
Keep the door shut and locked when machine is in operation.
If opening the door is necessary, be careful not to touch rotating or hot parts. Burns or serious injury
could result.
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
or to be burned.
4.4.1 Procedure to Start the Unit
Follow the starting procedure below.
（Manual operation）
① Switch "OFF" the circuit breaker on the
instrument panel.
② Set the selector switch “1” to “MANUAL”
operation position.
③ Turning the starter switch to the “RUN”
position, the engine starts preheating
automatically.
④ When the preheating lamp goes off, turn the
starter switch to “START” position and start
the engine.
⑤ Once engine has started, let it warm up about
five minutes at no-load condition.
⑥ Make sure that engine speed at no-load meets
62.5Hz(1.875min
-1 )
⑦ Adjust the voltage to the rated voltage by
turning the voltage regulator knob, watching
the voltmeter.
⑧ Switch the three-phase breaker “ON” to
supply generator power. To use auxiliary AC
power receptacles, switch the single-phase
and three-phase breakers to “ON” for power.
