Maintenance
6.1 General
A good maintenance program is the key to long compres-
sor life. Below is a program tha
t when adhered to, should
keep the compressor in top operating condition.
6.2 Daily operation
Prior to starting the compressor, it is necessary to per-
form a daily inspection.
Check the fluid level in the compressor receiver tank. Should
the level be low
, simply add the necessary amount. If the addi-
tion of fluid becomes too frequent, a simple problem has devel-
oped which is causing this excessive loss. Refer to Table 7-1:
Troubleshooting guide on p
age 51 under “Excessive fluid
consumption” for a probable cause and remedy.
After a routine start has been made, it is necessary to
pe
rform an inspection to ensure all operations are per-
forming correctly. Perform the following
inspections to
prevent unnecessary problems.
• Observe the instrument panel gauges and be
sur
e they monitor the correct readings for their
particular phase of operation.
• After the compressor has warmed up, it is rec-
ommended that a general check on the overall
compressor and instrument panel be made to
assure that the compressor is running properly.
• Check the air filter restriction gauge. Should it
indicate restriction, replace the elements imme-
diately. Refer to Section 6.9.5: Air filter mainte-
nance on page 46.
6.3 Maintenance after initial
50 hours of operation
After the initial 50 hours of operation, a few simple main-
tenance routines can rid the system of any possible for-
eign materials, if any. Perform the following maintenance
op
erations to prevent unnecessary problems.
• Clean the return line or
ifice and strainer.
• Change compressor fluid filter
6.4 Maintenance every 250 hours
Perform after every 250 hours of operation:
• Clean the cooler exterior. Depending on how
cont
aminated the atmosphere may be, more
frequent cooler cleaning may be necessary.
6.5 Maintenance every 300 hours
When not using Sullair AWF
®
, change the compressor
fluid and replace the fluid filter element. Refer to Section
6.9.4: Main fluid filter servicing on
page 46.
6.6 Maintenance every 600 hours
When not using Sullair AWF, replace the fluid filter ele-
ment only. Refer to Section 6.9.4: Main fluid filter servic-
ing on p
age 46.
6.7 Maintenance every 1000 hours
Perform after every 1000 hours of operation:
• Clean the return line or
ifice and strainer.
• Repack the wheel bearings on wheel-mounted
units.
