Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a
protective face shield and protective clothing.
Maximum air pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.
6.
Dry the aftercooler with compressed air. Direct the
air in the reverse direction of the normal flow.
Remove all fluid from the aftercooler. Ensure that
the aftercooler is dry.
7.
Inspect the aftercooler in order to ensure
cleanliness. Pressure test the aftercooler. If
necessary, replace the aftercooler.

Aftercooler Core - Inspect
Note:
Adjust the frequency of cleaning according to
the effects of the operating environment.
Inspect the aftercooler for these items: damaged fins,
corrosion, dirt, grease, insects, leaves, oil and other
debris. Clean the aftercooler, if necessary.

er procedure. When using pressure air, wear a

Maximum air pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.
After cleaning, start the engine and run the engine.
This will help in drying of the core. Stop the engine.
Inspect these items for good condition: Welds,
mounting brackets, air lines, connections, clamps
and seals. Make repairs, if necessary.

Alternator - Inspect
Perkins recommends a scheduled inspection of the
alternator. Inspect the alternator for loose
connections and correct battery charging. Check the
ammeter (if equipped) during engine operation in
order to ensure correct battery performance and/or
correct performance of the electrical system. Make
repairs, as required.
Check the alternator and the battery charger for
correct operation. If the batteries are correctly
charged, the ammeter reading should be very near
zero. All batteries should be kept charged. The
batteries should be kept warm because temperature
affects the cranking power. If the battery is too cold,
the battery will not crank the engine. When the
engine is not run for long periods of time or if the
engine is run for short periods, the batteries may not
fully charge. A battery with a low charge will freeze
more easily than a battery with a full charge.
