• Do not store anything inside of the generator set.

debris, plants, etc.).
NOTICE
All maintenance procedures must be performed or supervised by authorized
and trained service personnel only.
4.5 Generator Set Operation
WARNING
Combustible Vapors
Do not operate an engine 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 engine will result in longer life, better performance, and more
economical operation.
Cummins Inc. does not know how you will use your generator set. The equipment
owner and operator, therefore, is responsible for safe operation in the installation
site environment. Consult your authorized Cummins dealer for further information.
NOTICE
Diesel engines only: Cummins Inc. recommends the installation of an air
intake shutoff device or a similar safety device to minimize the risk of
overspeeding where an engine will be operated in a combustible
environment.
NOTICE
Long periods of idling (more than ten minutes) can damage an engine. Do
not idle the engine for excessively long periods.
Sequence of Operation
NOTICE
The following sequences are based on an approximate time duration. Your
generator set may vary slightly from the timing diagrams in this manual. All
referenced times are based on default control settings. The following
sequences are applicable to generator sets connected to an RA series
transfer switch.
