MAINTENANCE

6.1 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-
quir ed. S ee instr u c tions f or eac h item in

6.2 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.
S ee the Tr oubl eshooting S ec tion (6 . 8
sive Fluid Consumption for a probable cause and
remedy.
After a routine start has been made, observe the in-
strument panel gauges and be sure they monitor
the correct reading 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.
