Engine Starting Procedure (ISC NORMAL)
With throttle in idle position, turn ignition to the ON position allowing WAIT
TO START lamp to extinguish, then 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 3-5 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 damage to the engine.
ISM Series Engine
The maintenance guidelines found in the Cummins O & M manual is recom-
mended for the engine. When followed, it will help with a longer life, better per-
formance and more cost efficient operations. A good maintenance schedule
begins with a daily awareness of the engine and it’s 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 alternative
to CES 20071 is recommended. Lubricating oils meeting API CG-4 specifica-
tions may be used at a reduced drain interval. Monaco Coach Corporation uses
Pennzoil 15W-40 heavy duty engine lubricating oil that meets Cummins specifi-
cations. A critical factor in maintaining engine performance and durability is the
use of high grade multigrade lubricating oil and strict adherence to the mainte-
nance 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 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 effect the
engine warranty.
Oil additives should not be used unless the oil supplier or oil manufacturer
has been consulted and provided positive evidence or data establishing satisfac-
tory performance in the engine.
