4.3 Generator Set Operation
WARNING
Combustible Vapors
Do not operate a generator set where there are or can be combustible
vapors.
These vapors can be sucked through the air intake system and cause engine
acceleration and overspeeding, which can result in a fire, an explosion,
personal injury and extensive property damage.
Correct care of your generator set will result in longer life, better performance, and
more economical operation.
