With the throttle in the idle position, turn the key to the start position.
When the engine has started release the key. Allow the engine to idle with no
load for 3-5 to five minutes. The engine coolant temperature should be up to
normal operating range (140º F / 60º C to 212º F / 100º C) before operating
the engine under full throttle.
NOTE: The ISM engine does not have a “wait to start” feature.
The engine block heater may need to be plugged in 2 to 3 hours prior to
starting. The engine block heater is rated at 1500 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 peri-
ods of time. The block heater requires about 13 amps to operate.
The maintenance guidelines found in the Cummins O & M manual is
recommended for the engine. When followed it will help with a longer life,
better performance and more cost efficient operations. A good maintenance
schedule begins with a daily awareness of the engine and its various sys-
tems.
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. Monaco Coach
Corporation uses Pennzoil 15W-40 heavy duty engine lubricating oil that
meets Cummins specifications. A critical factor in maintaining engine per-
formance and durability 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 monitor-
ing 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
numerous variables which is the basis of the recommendation.
Synthetic oils API category III specifications are recommended for
extreme cold temperatures only.
Low viscosity oils used for winter operations will aid in starting.
Synthetic oils or oil with adequate low temperature properties used for Arctic
operations, where the engine can not be kept warm when shut down, will aid
in starting.
The use of synthetic oils should not be used to extend drain intervals.
Extended oil change intervals can decrease engine life and possibly affect the
engine warranty.
Oil additives should not be used unless the oil supplier or oil manufactur-
