5.2 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 engine starting, allow five minutes of unloaded warm-up.
Warming after starting is necessary for smooth engine operation. Do not operate the engine
at full load immediately after start up. This will shorten the equipment life.
During the warm-up operation, check the components for any looseness, leakage of water,
oil, fuel, or other problems.
Make sure that all safety indicator lamps turn off.
Be sure to operate the generator at the rated frequency, irrespective of the load capacity.
If the machine is operated with a frequency lower than rated, the generator may be
damaged.
