Stopping the Engine
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. Allow the
engine to run off load 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 you check the engine oil, do not
operate the engine for at least 10 minutes to allow
the engine oil to return to the oil pan.
• 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”.
• Check the crankcase oil level. Maintain the oil
level between the “MIN” mark and the “MAX” mark
on the engine oil level gauge.
• If necessary, perform minor adjustments. Repair
any leaks from the low-pressure fuel system and
from the cooling, lubrication, or air systems.
• Fill the fuel tank to help prevent accumulation of
moisture in the fuel. Do not overfill the fuel tank.
• Discoloration of the fuel can occur in the engine
fuel system and is acceptable as long as the fuel
meets the specifications in Perkins Diesel Engines
Fluids Recommendations, M0113102. Refer to
your Perkins distributor for further information.
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.
• Allow the engine to cool. Check the coolant level.
• Check the coolant for correct antifreeze protection
and the correct corrosion protection. Add the
correct coolant/water mixture, if necessary.
• Perform all required periodic maintenance on all
driven equipment. This maintenance is outlined in
the instructions from the OEM.
