MAINTENANCE

8.1 INTRODUCTION
WARNING
!
Before doing compressor maintenance, discon-
nect compressor from power source and lock out
power source. Isolate compressor from line pres-
sure by closing recommended discharge shut-off
valve and releasing all internal pressure from
compressor.
As you proceed in reading this section, it will be easy
to see that the maintenance program for the air com-
pressor is quite minimal. The Supervisor monitors
the status of the separator element. When mainte-
nance to this device is required, the Supervisor will
display the appropriate maintenance message and
flash the location LED on the graphics map as a
visual reminder. See instructions for each item in
Section 8.6, Parts Replacement and Adjustment
procedures.
WARNING
!
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pressure
before doing so.
8.2 DAILY OPERATION
Prior to starting the compressor, it is necessary to
check the fluid level in the sump. Should the level be
low, simply add the necessary amount. If the addi-
tion of fluid becomes too frequent, a minor problem
has developed which is causing this excessive loss.
See the Troubleshooting Section under Excessive
Fluid Consumption for a probable cause and reme-
dy.
After a routine start has been made, a general check
of the overall compressor should be made to assure
that the compressor is running properly.
8.3 MOTOR BEARING LUBRICATION
WARNING
!
Before doing compressor maintenance, discon-
nect compressor from power source and lock out
power source. Isolate compressor from line pres-
sure by closing recommended discharge shut-off
valve and releasing all internal pressure from
compressor.

See motor manufacturer’s lubrication instructions.
8.4 FLUID FILTER MAINTENANCE
WARNING
!
Fluid filter has internal bypass. DO NOT SUBSTI-
TUTE.
Refer to figure 8-1 and 8-2. Replace the fluid filter
element under any of the following conditions:
1. As recommended in the Lubrication Guide in the
Specification Section.
2. Every fluid change.
8.5 COOLER MAINTENANCE
If cooler becomes restricted, use standard spray de-
greaser/cleaner and brush to clean cooler. Use air
pressure to blow cooler clean. Care must be taken
as not to damage cooler fins.
WARNING
!
Before doing compressor maintenance, discon-
nect compressor from power source and lock out
power source. Isolate compressor from line pres-
sure by closing recommended discharge shut-off
valve and releasing all internal pressure from
compressor.
