Avoid to let the engine run out of
fuel. If it happened, priming will
speed up the starting.
Avoid long low-load periods
(< 30%). In this case, an output
drop and higher oil consumption of
the engine could occur. Refer to
'Preventing low loads'.
The generator's doors may only
remain opened for short periods
during operation, to carry out
checks for example.
