With throttle in idle position, turn ignition to the ON position allowing
WAIT TO START lamp to extinguish. Turn key to the start position. When
the engine is started the grid heater will again energize for a time period
determined by the intake air temperature and the fuel temperature. Allow
engine to idle with no load for three to five minutes. The engine coolant
temperature should be up to normal operating range (140º F/60 º C to
212º F/100º C) before operating engine under full throttle.
NOTE: It is not recommended to idle the engine for long
periods of time. This will simply waste fuel and annoy
neighbors. Consistent periods of long idle may cause dam-
age to the engine.
The engine block heater may need to be plugged in two to three hours
prior to starting. The engine block heater is rated at 1,500 watts, 110 Volts
AC and requires the motorhome be plugged into shore power or have the
generator running. It is not necessary to leave the block heater plugged in for
long periods of time. The block heater requires about 13 amps to operate.
The maintenance guidelines found in the Cummins Operation &
Maintenance Manual is recommended for the engine. When followed it will
help with a longer life, better performance and more cost efficient opera-
tions. A good maintenance schedule begins with a daily awareness of the
engine and its various systems.
A high grade 15W-40 multiviscosity heavy duty lubricating oil meeting
Cummins Engineering Specification CES 20071 or CES 20076, American
Petroleum Institute (API) specification CH-4 which can be used as an alter-
native to CES 20071 is recommended. Lubricating oils meeting API CG-4
specifications may be used at a reduced drain interval. The engine uses
Pennzoil 15W-40 heavy duty engine lubricating oil that meets Cummins
specifications. A critical factor in maintaining engine performance and durabil-
ity is the use of high grade multigrade lubricating oil and strict adherence to
the maintenance service intervals.
A straight weight or monograde lubricating oil is not recommended.
Shortened drain intervals may be required as determined by a close monitoring
of the lubricating oil condition by means of a oil sampling program. The use
of oil analysis to extend drain interval is not recommended. There are numer-
ous variables which is the basis of the recommendation.
