4.8 Operation and Stopping
Keep the output terminal cover shut and locked whenever
the machine is running.
Notice that the voltage of several hundreds volt is applied
to the output terminal and control board.
When opening the door unavoidably, be careful not to
touch the rotating parts and hot parts. It could cause
scalding and serious injury.
When removing or connecting a connecting cable for
changing load, be sure to switch OFF the circuit breaker,
remove the starter key from the starter switch, then carry
out a work. The operator must keep the key during
operation.
Neglecting the cautions mentioned above, and a third party
starting the machine during operation may cause serious
accidents such as electric shock.
When the breaker functions so often during operation, reduce the load.
When using single- phase load, check the current of each phase and try to keep the load of each
phase constantly average.
If you continue to operate the generator main unit, ignoring and neglecting these cautions, it could
cause burning to the unit and resulting in fire. Furthermore, should continue operation at the lower
level than the standard rated frequency, it could cause burns to the generator main unit and also the
motor of the load.
Do not, under any circumstance, open the portions
below during operation.
Coolant drain valve and plug
Engine oil drain valve and plug
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.
Never touch the interior of output terminals ,control board
Pay caution to overload and unbalanced load
Draining during operation prohibited
