Stopping The Engine - Northern Lights OM-C3 Operator's Manual

Stopping the Engine

IMPORTANT: Before stopping an engine that
has been operating at working load, idle
engine at least 5 minutes at 1000–1200 rpm
to cool hot engine parts.
Engines in generator set applications where
the engine controller (ECU) is locked at a
specified speed and no slow idle function is
available, run engine for at least 5 minutes
at fast idle and no load.
1. Remove load from engine or shift marine gear to
"NEUTRAL" and run engine for at least 5 minutes at
1000–1200 rpm to allow coolant and oil to carry heat
away from the combustion chamber, turbocharger,
pistons, and bearings.
2. Turn key switch (A) to "OFF" position and remove key
from ignition.
3. If vessel will not be used for several days, close fuel
valves and sea cock.
4. Turn main electrical power switch to "OFF", if equipped.
5. Fill the fuel tank to minimize possible water
condensation problems. Filling tanks at end of day
drives out moisture-laden air.
6. For Heat Exchanger Engines: If the engine will be
subjected to temperatures at or below 0° C (32° F),
open the sea water pump end cover to drain the sea
water from the system to prevent freezing. The sea
water pump will require priming before starting the
engine.

7. Observe the hour meter reading on diagnostic
gauge/hour meter (C) to determine if periodic
maintenance is necessary. Make appropriate entries
in maintenance logs. (See LUBRICATION AND
MAINTENANCE RECORDS Section.)
8. Perform required periodic maintenance on all other
equipment, as recommended by the equipment
manufacturers.
