Stoppin g the Eng ine
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 tur-
bocharger 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 five 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.

After Stopping Engine
Note: Before y
ou check the engine oil, do not operate
the engine for at least 10 minutes in order to allow
the engine oil to return to the oil pan.
Contact wit
h high pressure fuel may cause fluid
penetration and burn hazards. High pressure fu-
el spray may cause a fire hazard. Failure to fol-
low these i
nspection, maintenance and service in-
structions may cause personal injury or death.
•
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 servi
ce or repair is performed on the engine
fuel lines. If necessary, perform minor adjustments.
Repair any leaks from the low pressure fuel
system a
nd 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
betwee
n the “MIN” mark and the “MAX” mark on
the engine oil level gauge.
•
If the e
ngine is equipped with a service hour meter,
note the reading. Perform the maintenance that
is in the Operation and Maintenance Manual,
“Main
tenance Interval Schedule”.
•
Fill the fuel tank in order to help prevent
accu
mulation of moisture in the fuel. Do not overfill
the fuel tank.
NOTICE
Only use antifreeze/coolant mixtures recommended in
the
Refill Capacities and Recommendations topic that
is in this Operation and Maintenance Manual. 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 pres-
sure.
•
Allow the engine to cool. Check the coolant level.
