6.1 GENERAL

WARNING
Before doing compressor mainte-
nance, disconnect compressor from
power source and lock out power
source. Isolate compressor from line
pressure by closing recommended
discharge shut-off valve and releas-
ing all internal pressure from com-
pressor.
As you proceed in reading this section, it will be
easy to see that the Maintenance Program for the
air compressor is quite minimal yet important. See
instructions for each item in Section 6.6, Parts
Replacement and Adjustment Procedures.
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
addition of fluid becomes too frequent, a minor
problem has developed which is causing this
excessive loss. See the Troubleshooting Section
(6.7) under Excessive Fluid Consumption
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.
