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.

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
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.
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.
• After the engine has stopped, you must wait for 10
minutes 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. 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”.
• 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
that is in the Operation and Maintenance Manual,
“Maintenance Interval Schedule”.
• Fill the fuel tank, to help prevent accumulation of
moisture in the fuel. Do not overfill the fuel tank.
NOTICE
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.
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
