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
in order 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 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 keyswitch to the OFF position. If
necessary, refer to the instructions that are
provided by the OEM.
3. Disconnecting the battery power too soon may
prevent purging of the DEF fluid lines after the
engine is shut down. Refer to this Operation and
Maintenance Manual, "Battery Disconnect Switch"
for more information.
Emergency Stopping
NOTICE
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
i05857035
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. Refer to this
Operation and Maintenance Manual, "Battery
Disconnect Switch" for more information.
• 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".
• Before you check the engine oil, do not operate
the engine. Wait for at least 10 minutes after the
engine has stopped in order to allow the engine oil
to return to the oil pan. Check the crankcase oil
level. Maintain the oil level between the "MIN"
mark and the "MAX" mark on the engine oil level
gauge.
• If the engine is equipped with a service hour
meter, note the reading. Perform the maintenance
i05195199
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 tank.
• Fill the DEF tank, a low level of DEF in the tank
can result in engine de-rate.
Only use antifreeze/coolant mixtures recommended
in this Operation and Maintenance Manual, "Refill
Capacities and Recommendations" topic or in this
Operation and Maintenance Manual, "Fluid Recom-
mendations" topic. Failure to do so can cause engine
damage.
