NOTICE
If equipped with an auxiliary oil filter system or a re-
mote oil filter system, follow the OEM or filter manu-
facturer's recommendations. Under filling or
overfilling the crankcase with oil can cause engine
damage.
NOTICE
To prevent crankshaft bearing damage, crank the en-
gine with the fuel OFF. This will fill the oil filters before
starting the engine. Do not crank the engine for more
than 30 seconds.
2. Start the engine and run the engine at “LOW IDLE”
for two minutes. Perform this procedure to ensure
that the lubrication system has oil and that the oil
filters are filled. Inspect the oil filter for oil leaks.
3. Stop the engine and allow the oil to drain back to
the sump for a minimum of ten minutes.

4. Remove the oil level gauge to check the oil level.
Maintain the oil level between the “MIN” and
“MAX” marks on the oil level gauge.

Engine Valve Lash - Inspect/
Adjust
This maintenance is recommended by Perkins as
part of a lubrication and preventive maintenance
schedule in order to help provide maximum engine
life. The maintenance for the valve lash is important
in order to keep the engine compliant.
NOTICE
Only qualified service personel should perform this
maintenance. Refer to the Service Manual or your au-
thorized Perkins dealer or your Perkins distributor for
the complete valve lash adjustment procedure.
Operation of Perkins engines with incorrect valve
lash can reduce engine efficiency, and also reduce
engine component life.
Ensure that the engine can not be started while
this maintenance is being performed. To help pre-
vent possible injury, do not use the starting motor
to turn the flywheel.
Hot engine components can cause burns. Allow
additional time for the engine to cool before
measuring/adjusting valve lash clearance.
Ensure that the engine is stopped before measuring
the valve lash. The engine valve lash can be
inspected and adjusted when the temperature of the
engine is hot or cold.
Refer to Systems Operation, Testing and Adjusting,
“Engine Valve Lash - Inspect/Adjust” for more
information.

Fuel Injector - Test/Change
Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire.
Make sure that you wear eye protection at all
times during testing. When fuel injection nozzles
are tested, test fluids travel through the orifices
of the nozzle tip with high pressure. Under this
amount of pressure, the test fluid can pierce the
skin and cause serious injury to the operator. Al-
ways keep the tip of the fuel injection nozzle
pointed away from the operator and into the fuel
collector and extension.
NOTICE
Do not allow dirt to enter the fuel system. Thoroughly
clean the area around a fuel system component that
will be disconnected. Fit a suitable cover over any
disconnected fuel system components.
Regular maintenance of the fuel injectors is
recommended by Perkins. The fuel injectors must be
removed and tested by an authorized agent. The fuel
injectors should not be cleaned as cleaning with
incorrect tools can damage the nozzle. The fuel
injectors should be renewed only if a fault with the
fuel injectors occurs. Some of the problems that may
indicate that new fuel injectors are needed are listed
below:
