9.1 INTRODUCTION

Before doing compressor or dryer maintenance,
disconnect compressor from power source and
lock out power source. Isolate compressor/dryer
from line pressure by closing recommended dis-
charge shut---off valve and releasing all internal
pressure from compressor/dryer.
As you proceed in reading this section, it will be
easy to see that the maintenance program for the
air compressor is quite minimal. The Supervisor II
monitors the status of the separator element. When
maintenance to this device is required, the Supervi-
sor II will display the appropriate maintenance
message and flash the location LED on the graph-
ics map as a visual reminder. See instructions for
each item in Section 9.6, Parts Replacement and
Adjustment Procedures.
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pres-
sure before doing so.

9.2 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
addition of fluid becomes too frequent, a minor
problem has developed which is causing this ex-
cessive loss. See the Troubleshooting---Compres-
sor section under Excessive Fluid Consumption for
a probable cause and remedy.
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.

9.3 MOTOR BEARING LUBRICATION

Before doing compressor/dryer maintenance,
disconnect compressor from power source and
lock out power source. Isolate compressor/dryer

See motor manufacturer's lubrication instructions.

9.4 FLUID FILTER MAINTENANCE

Fluid filter has internal bypass. DO NOT SUBSTI-
TUTE.
Replace the fluid filter element under any of the fol-
lowing conditions:
1. As recommended in the
Specification Section.
2. Every year.
3. Every fluid change.

9.5 COOLER MAINTENANCE

If cooler becomes restricted, use standard spray
degreaser/cleaner and brush to clean cooler. Use
air pressure to blow cooler clean. Care must be tak-
en as not to damage cooler fins.
Before doing compressor/dryer maintenance,
disconnect compressor from power source and
lock out power source. Isolate compressor/dryer
from line pressure by closing recommended dis-
charge shut---off valve and releasing all internal
pressure from compressor/dryer.
9.6 PARTS REPLACEMENT AND ADJUSTMENT
PROCEDURES
Before doing compressor/dryer maintenance,
disconnect compressor from power source and
lock out power source. Isolate compressor/dryer
from line pressure by closing recommended dis-
charge shut---off valve and releasing all internal
pressure from compressor/dryer.
RELIEF VALVE
Check the relief valve at least weekly to see that it is
functional. DO NOT tamper with the preset factory
pressure setting of the valve. DO NOT plug the
valve for any reason; should it leak, have it re-
placed.
