Stopping the Engine
NOTICE
Stopping the engine immediately after it has been
working under load, can result in overheating and ac-
celerated wear of the engine components.
See the following stopping procedure, to allow the
engine to cool, and to prevent excessive tempera-
tures in the turbocharger center housing, which could
cause oil coking problems.
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. (if equipped)
2. Turn the engine start switch to the OFF position
and remove the key.
Note: The engine may delay before completely
shutting down. Delayed engine shutdowns aid in
cooling the engine and after-treatment (if equipped)
components.
Delayed Engine Shutdown (If
Enabled)
The Delayed Engine Shutdown allows the engine to
run for a time after the engine start switch key is
turned to the OFF position to cool the engine and
system components. The engine start switch key
may be removed.
Note: Do not turn off the battery power disconnect
switch until the battery disconnect switch indicator
lamp has turned off. If the switch is operated
prematurely, 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.
Leaving the machine unattended when the engine
i07831439
is running may result in personal injury or death.
Before leaving the machine operator station, neu-
tralize the travel controls, lower the work tools to
the ground and deactivate all work tools, and
place the lever for the hydraulic lockout control
in the LOCKED position.
Note: Leaving the engine unattended while running
may result in property damage in the event of a
malfunction.
Turn the engine start switch to the OFF position.
displayed, ENGINE COOLDOWN ACTIVE.
Delayed engine shutdown will run whenever the
exhaust temperature is above a threshold at engine
shutdown. Delayed engine shutdown will run for a
minimum of 76 seconds and will continue to run until
the engine and system components are cooled. The
default maximum run time is 7 minutes.
Note: An authorized dealer can change the
maximum run time value up to 30 minutes, but the
default setting is 7 minutes.
Note: To override delayed engine shutdown and stop
the engine, turn the engine start switch to the STOP
position. Overriding delayed engine shutdown may
reduce engine and system component life. A warning
message and/or audible alarm will be initiated and a
fault code will be logged for improper engine
shutdown.
