Section 1 - Operating Instructions Page 1-3
WARNING
DO NOT OPERATE A DIESEL ENGINE WHERE THERE
ARE OR CAN BE COMBUSTIBLE VAPORS. The
vapors can be sucked through the air intake system
and cause engine acceleration and overspeeding that
can result in a fire, an explosion, and extensive
property damage. Numerous safety devices are
available, such as air intake shutoff devices, to
minimize the risk of overspeeding where an engine,
due to its application, might operate in a combustible
environment, such as due to a fuel spill or gas leak.
Remember, Cummins has no way of knowing the use
you have for your engine. THE EQUIPMENT OWNER
AND OPERATOR ARE RESPONSIBLE FOR SAFE
OPERATION IN A HOSTILE ENVIRONMENT.
CONSULT YOUR CUMMINS AUTHORIZED REPAIR
LOCATION FOR FURTHER INFORMATION.
Cummins recommends the installation of an air intake
shutoff device or a similar safety device to minimize
the risk of overspeeding when an engine is operating
in a combustible environment, such as due to a fuel
spill or gas leak.
CAUTION
Do not expose the engine to corrosive chemicals.
Corrosive chemicals can damage the engine.
