Stoppin g the Eng ine
NOTICE
Stopping the engine immediately after it has been
working under load can result in overheating and ac-
celerated wear of the engine components.
If the engine has been operating at high rpm and/or
high loads, run at low idle for at least three minutes
to reduce and stabilize internal engine temperature
before stopping the engine.
Avoiding hot engine shutdowns will maximize tur-
bocharger shaft and bearing life.
Prior to stopping an engine that is being operated
at low loads, operate the engine at low idle for 30
seconds before stopping. If the engine has been
operating at highway speeds and/or at high loads,
operate the engine at low idle for at least three
minutes. This procedure will cause the internal
engine temperature to be reduced and stabilized.
Ensure that the engine stopping procedure is
understood. Stop the engine according to the shutoff
system on the engine or refer to the instructions that
are provided by the OEM.
•
To stop the engine, turn the ignition key switch to
the OFF position.

After Stopping Engine
Note: Before yo
u check the engine oil, do not operate
the engine for at least 10 minutes in order to allow
the engine oil to return to the oil pan.
•
Check the crankcase oil level. Maintain the oil level
between the “ADD” mark and the “FULL” mark on
the oil level d
ipstick.
•
If necessary, perform minor adjustments. Repair
any leaks and
tighten any loose bolts.
•
Note the required service interval. Perform
the maintena
nce that is in the Operation and
Maintenance Manual, “Maintenance Interval
Schedule”.
•
Fill the fuel tank in order to help prevent
accumulation of moisture in the fuel. Do not overfill
the fuel tan
k.
NOTICE
Only use antifreeze/coolant mixtures recommended in
the Coolant Specifications that are in the Operation
and Mainten
ance Manual. Failure to do so can cause
engine damage.
•
Allow the en
gine to cool. Check the coolant level.
•
If freezing temperatures are expected, check the
coolant fo
r the correct antifreeze protection. The
cooling system must be protected against freezing
to the lowest expected outside temperature. Add
the correc
t coolant/water mixture, if necessary.
•
Perform all required periodic maintenance on all
driven equ
ipment. This maintenance is outlined in
the instructions from the OEM.
