Stopping
the
Engine
NOTICE
Stopping the engine immediately after working under
load, can result in overheating and accelerated wear
of the engine components.
Refer to the following stopping procedure, to allow
the engine to cool, and to prevent excessive temper-
atures in the turbocharger center housing and DEF
injector.
Positions of the engine key switch are indicated by a
film that surrounds the engine key switch.
Your machine may be equipped with a Type 1 film or
your machine may be equipped with a Type 2 film.
Both the Type 1 film and the Type 2 film are shown

1.
While the machine is stopped, run the engine for 5
minutes at low idle. Idling the engine allows hot
areas of the engine to cool gradually.
Note:
If the
“
Regen Active
”
indicator is illuminated,
do not shut off the engine. Refer to Operation and
Maintenance Manual, “Monitoring System” for more
information on indicators.
2.
Turn the engine key switch to OFF position (2) and
remove the key.
Note:
The engine may delay before completely
shutting down. Delayed engine shutdowns aid in
cooling the engine and after-treatment components.
Delayed Engine Shutdown (If
Enabled)
The Delayed Engine Shutdown allows the engine to
run for a time after the engine key switch is turned to
the OFF position to cool the engine and system
components. The key may be removed from the
engine key switch.
Note:
The DEF purge process will run for 2 minutes
once the engine is shut down and must complete.
The purge process may occur during delayed engine
shutdown. Do not turn off battery disconnect switch
during the purge process. Do not turn off the battery
power disconnect switch until the battery disconnect
switch indicator lamp has turned off. If the purge
process does not complete, a diagnostic code will
become active.
Note:
There may be regulations that define the
requirements for the operator and/or support
personnel to be present when the engine is running.
