2.3 Lube oil level of engine
When starting the generator, check oil level. If the oil is insufficient, add lube oil to the stipulated level. Draining off lube oil
can be immediately done after engine stopped. It is difficult to drain off the oil thoroughly when the engine is in its cold state.
The engine may be damaged if operated with insufficient lube oil. It is also dangerous to supply too much lube oil to the
engine because a sudden increase in engine rpm could be caused by its combustion. Always check the lube oil level before
starting the engine and refill if necessary.
