7.1 GENERAL

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 use of the service
indicators provided for the bearing filter, air filter and
fluid separator, will alert you when service mainte-
nance is required. When the maintenance gauge
shows red, maintenance for that specific item is re-
quired. See instructions for each item in Section 7.8,

Parts Replacement and Adjustment procedures.

7.2 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 simple 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, observe the in-
strument panel gauges and be sure they monitor
the correct readings for their particular phase of op-
eration. After the compressor has warmed up, it is
recommended that a general check on the overall
compressor and instrument panel be made to as-
sure that the compressor is running properly.
DO NOT remove caps, plugs, and/or other compo-
nents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pressure
before doing so.
7.3 MAINTENANCE AFTER INITIAL 50 HOURS OF
OPERATION
After the initial 50 hours of operation, a few mainte-
nance requirements are needed to clean the system
of any foreign materials. Perform the following main-
tenance operations to prevent unnecessary prob-
lems.
1. Clean the return line strainer.
2. Clean the return line orifice.

7.4 MAINTENANCE EVERY 1000 HOURS

After 1000 hours of operation, it will be necessary to
perform the following:
1. Clean the return line strainer.
2. Replace the fluid filter element and gasket.

7.5 FLUID MAINTENANCE

Drain the sump and change the compressor fluid
using instructions shown in sections 3.2, 3.3, and
3.4.

ments must be replaced. DO NOT clean the separa-
tor elements.
7.8 PARTS REPLACEMENT AND ADJUSTMENT
PROCEDURES
FLUID FILTER ELEMENT REPLACEMENT

1. Using a strap wrench, remove the old element
and gasket.
2. Clean gasket seating surface.
3. Apply a light film of fluid to the new gasket.
4. Hand tighten new element until new gasket is
seated in the gasket groove. Avoid any nicks,
cuts or pinches to the gasket.
5. Continue tightening element by hand an addition-
