Engine Stopping

Stopping the Engine
NOTICE
Stopping the engine immediately after the engine has
been working under load, can result in overheating
and accelerated wear of the engine components.
Avoid accelerating the engine prior to shutting down
the engine.
Avoiding hot engine shutdowns will maximize turbo-
charger shaft and bearing life. Also, selective cata-
lytic reduction component life.
Note: Individual applications will have different
control systems. Ensure that the shutoff procedures
are understood. Use the following general guidelines
to stop the engine.
1. Remove the load from the engine. Reduce the
engine speed to low idle. Allow the engine to idle
for 5 minutes to cool the engine.
2. Stop the engine after the cool down period
according to the shutoff system on the engine and
turn the ignition keyswitch to the OFF position. If
necessary, refer to the instructions that are
provided by the OEM.
Note: In some applications the engine will continue
to operate after the keyswitch is turned to the OFF
position. The engine will operate for a short time to
allow engine components to cool.
3. Allow at least 2 minutes after the engine has
stopped before you turn the battery disconnect
switch to OFF. Disconnecting the battery power
too soon will prevent the engine electronic control
module storing information from the engine and
aftertreatment sensors.
Delayed Engine Shutdown (if
Equipped)
The delayed engine shutdown allows the engine to
run for a time after the engine start switch is turned to
the OFF position to cool the system components.
The engine start switch key may be removed.
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
i08046179
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.
Leaving the engine unattended while running may
result in property damage in the event of a
malfunction.
Note: An authorized dealer can change the
maximum run time value up to 30 minutes but the
default setting is 10 minutes.
An override can be enabled so that the delayed
engine shutdown will not operate. Overriding delayed
engine shutdown may reduce engine and system
component life. The override is operated by the
keyswitch.
At any time during a delayed engine shutdown, the
engine start switch may be turned to the ON position.
The engine may be placed back into service.
Emergency Stopping
Emergency shutoff controls are for EMERGENCY
use ONLY. DO NOT use emergency shutoff devices
or controls for normal stopping procedure.
The OEM may have equipped the application with an
emergency stop button. For more information about
the emergency stop button, refer to the OEM
information.
Ensure that any components for the external system
that support the engine operation are secured after
the engine is stopped.
After Stopping Engine
Note: Before you check the engine oil, do not
operate the engine. Wait for at least 30 minutes after
the engine has stopped to allow the engine oil to
return to the oil pan.
