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 WS
Controller™ display indicates service, maintenance for
that specific item is required. See instructions for each
item in Section 6.6: Filter maintenance on
page 56.
6.2 Daily operation
Prior to starting the compressor, it is necessary to check
the fluid level in the separator/sump tank. 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
Section 6.14.2: Troubleshooting guide
on page 59 under
“Excessive compressor fluid consumption” for a probable
ca
use and remedy.
After a routine start has been made, observe the control-
ler display and be sure it monitors the correct readings
for
their particular phase of operation. After the compres-
sor has warmed up, it is recommended that a general
che
ck 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 for-
eign materials. Perform the following maintenance opera-
tions to prevent unnecessary problems:
• Clean the return line
strainer. Refer to Dis-
charge, separator/sump and piping system of
the Parts Manual for location.
• Clean the return line orifice.
6.4 Maintenance every 2000 hours
After 2000 hours of operation, it will be necessary to per-
form the following:
• Clean the return line
strainer. Refer to Dis-
charge, separator/sump and piping system of
the Parts Manual for location.
• Replace the fluid filter element.
• Pull oil sample for analysis.
• Check air filter. Change if necessary.
6.5 Fluid maintenance
For Sullube
®
, change fluid every 10,000 hours or 1 year,
whichever comes first. Drain the separator/sump tank
and change the compressor fluid using instructions
shown in Section 3.7: Lubrication change recommenda-
tions and maintenance, fluid on p
age 25.
WARNING
Before any repairs are attempted, refer to Sec-
tion 1: Safety before proceeding.
WARNING
High-pressure hazard!
• Do
not remove caps, plugs, and/or other
components when compressor is run-
ning or pressurized. Stop compressor
a
nd relieve all internal pressure before
doing so.
• Failure to comply could re
sult in death or
serious injury.
