Engine Stopping
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.
Avoid accelerating the engine prior to shutting it
down.
Avoiding hot engine shutdowns will maximize turbo-
charger shaft and bearing life.
Note: Individual applications will have different
control systems. Ensure that the shutoff procedures
are understood. Use the following general guidelines
in order to stop the engine.
1. Remove the load from the engine. Reduce the
engine speed (rpm) to low idle. Allow the engine to
idle for 5 minutes in order 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 key switch to the OFF position. If
necessary, refer to the instructions that are
provided by the OEM.
3. Allow 2 minutes after the engine has stopped
before you turn the battery disconnect switch to
OFF. Disconnecting the battery power too soon
will prevent purging of the diesel exhaust fluid
lines after the engine is shut down.
Emergency Stopping
NOTICE
Emergency shutoff controls are for EMERGENCY
use ONLY. DO NOT use emergency shutoff devices
or controls for normal stopping procedure.
Ensure that any components for the external system
that support the engine operation are secured after
the engine is stopped.

Typical emergency stop button
The emergency stop button is in the OUT position for
normal engine operation. Push the emergency stop
button. The engine will not start when the button is
locked. Turn the button clockwise in order to reset.
Refer to Operation and Maintenance Manual,
"Features and Controls" for the location and the
operation of the emergency stop button.
After Stopping Engine
Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.

• Diesel Exhaust Fluid (DEF) purge, do not
disconnect the battery disconnect switch until the
DEF purge has been completed. The procedure is
automatically controlled and will take
approximately 2 minutes.
• After the engine has stopped, you must wait for 10
minutes in order to allow the fuel pressure to be
purged from the high-pressure fuel lines before
any service or repair is performed on the engine
fuel lines. The 10 minute wait will also allow static
charge to dissipate from the low-pressure fuel
system. If necessary, perform minor adjustments.
Repair any leaks from the low-pressure fuel
system and from the cooling, lubrication, or air
systems. Replace any high-pressure fuel line that
has leaked. Refer to Disassembly and Assembly
Manual, "Fuel Injection Lines - Install".
