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 simple. The use of the service
indicators provided for the fluid filter, air filter and fluid
separator, will alert you when service maintenance is
required. When the microprocessor display indicates
service, maintenance for that specific item is required.
See instructions for each item in Section 6.6, Filter
Maintenance.
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 simple problem has developed
which is causing this excessive loss. See the
Troubleshooting Guide Section under EXCESSIVE
COMPRESSOR FLUID CONSUMPTION for a probable
cause and remedy.
After a routine start has been made, observe the
controller display and be sure it monitors the correct
readings for their particular phase of operation. After the
compressor has warmed up, it is recommended that a
general check on the overall compressor be made to
assure that the compressor is running properly.
6.3 MAINTENANCE AFTER INITIAL 50
HOURS OF OPERATION
After the initial 50 hours of operation, a few maintenance
requirements are needed to clean the system of any
foreign materials. Perform the following maintenance
operations to prevent unnecessary problems.
1. Clean the return line strainer (refer to 6.4, for
location).
2. Clean the return line orifice.
6.4 MAINTENANCE EVERY 2000
HOURS
After 2000 hours of operation, it will be necessary to
perform the following:
1. Clean the return line strainer (refer to8.10, for
location).
2. Replace the fluid filter element.
