GeneralInformation
Correct care of your engine will result in longer life, better performance, and more economical operation.
•Follow the daily maintenance checks listed in Maintenance Guidelines,Section 2.
•Check the oil pressure indicators,temperature indicators,warning lightsand other gauges daily to make
sure they are operational.
Warning: DO NOT OPERATE A DIESEL ENGINE WHERE THERE ARE OR CAN BE COMBUSTIBLE
VAPORS. These vapors can be drawn through the air intake system and cause engine acceleration and
over-speeding, which can result in a fire, an explosion and/or extensive property damage. Numerous
safety devices are available, such as air intake shutoff devices,to minimize the risk of over-speeding
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.
Starting Procedure
Automotive- (Bosch VE and P-Pumps with RQV-K Governor) above 16 “C [60 °F]
Foot off throttle. The VE pump has an internal starting circuit to provide starting fuel delivery. The inline
pump delivers sufficient fuel to start engine with throttle at idle.
Automotive- (Bosch VE and P-Pumps with RQV-K Governor) below 16 'C [60 °F]
Foot at full throttle while cranking. The VE pump has an internal circuit to provide starting fuel delivery,
and open throttle helps keep the engine operating, once started. The inline pump requires open throttle
to position and hold the rack in the maximum fuel position.
Industrial/Marine- (Bosch VE, Lucas DPA, Stanadyne DP4, Nippondenso EP-9) above 0 °C [32 °F]
Foot off throttle. The VE pump has an internal starting circuit to provide starting fuel delivery. The DPA
pump has a metering valve which will remain in start position if cranking speed does not approach idle
speed. The EP-9 pump has a “Start Spring” which automatically moves the rack to the start fuel position.
