6.1 GENERAL
Asyouproceed inreading thissection, itwill beeasy
to see that the Maintenance Program for the air
compressor is quite minimal. The use of the service
indicators provided forthe 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 S ec tion 6 . 7 ,
Parts Replacement and Adjustment Procedures.
6.2 DAILY OPERATION
Prior to starting the compressor, it is necessary to
check the fluid level inthesump. Should the level be
low, simply add the necessary amount. If the addi-
tionoffluid becomes too frequent, asimple problem
has developed which iscausing this excessive loss.
S ee the Tr oubl eshooting S ec tion (6 . 8 ) under Ex c es -
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.

nents when compressor is running or pressur-
ized.
