6.5.3 CHECKING THE COMPRESSOR OIL
Having the proper amount of oil in the compressor
system is essential to prolonging the equipment’s useful
life. Checking the compressor oil is the most important
service to perform on the 300 Series All-In-One Power
System package. Consult
Section 6.3, Maintenance
Schedule Table
for routine compressor oil inspection
intervals.
Consult
Figure 6-4
and the following procedure to check
the compressor oil.
1. With the machine off and the ignition key
removed, open the hood panel.
2. Locate the fill port end of the compressor oil
fill tube [
A
], and unscrew and remove the
compressor oil fill cap/dipstick [
B
].
3. Wipe off dipstick and insert it back into port.
4. Remove stick and inspect the oil mark.
5. Verify that the oil level is within the range
indicated by wet level mark on dipstick [
D
],
as per
Figure 6-4
.
DANGER
NEVER check the compressor oil level
with the compressor running. Hot oil is
under pressure and will spray, causing
severe burns.
When checking compressor oil level,
blow down the pressure to zero, and
allow system oil level to settle before
removing the fill cap/dipstick.
NOTE
This procedure should only be
performed when the compressor is warm
immediately after extended operation.

WARNING
Relieve pressure from the compressor
system before removing any
components.
NOTE
The cooler has an aluminum core and if
internal cleaning is required, it should be
done at a qualified radiator shop. If the
lubrication system is properly
maintained (changing the oil and filters
at the recommended intervals) an
internal cleaning should not be
necessary during the compressor’s
service life.
NOTE
Using a brake cleaner to wipe down the
dipstick before determining oil level will
give a clear indication of oil level on the
stick.
