MAINTENANCE

7.1 GENERAL
As you proceed in reading this section, it will be
easy to see that the Maintenance Program for the
air compressor is quite minimal yet important. 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 mainte-
nance gauge shows red, maintenance for that spe-
cific item is required. See instructions for each item
in Section 7.7, Parts Replacement and Adjustment
Procedures.
7.2 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. Frequent
fluid additions to maintain correct level would be
indicative of excessive fluid consumption, and
should be investigated - see the Troubleshooting
Section of this manual for probable cause and rem-
edy.
After a routine start has been made, observe the
instrument panel gauges and be sure they monitor
the correct readings for that particular phase of
operation. After the compressor has warmed up, it
is recommended that a general check of the overall
compressor and instrument panel be made to
assure that the compressor is running properly.
7.3 MAINTENANCE AFTER INITIAL 50 HOURS OF
OPERATION
After the initial 50 hours of operation, a few mainte-
nance requirements are needed to rid the system of
any possible foreign materials. Perform the follow-
ing maintenance operations to avoid operational
problems:
1. Clean the return line strainers.
2. Clean the return line orifices.
3. Clean the compressor unit gear housing, bearing
and shaft seal orifices.
4. Change the fluid filter element.
5. Clean the control line filters.
7.4 MAINTENANCE AFTER 1000 HOURS
After 1000 hours of operation, it will be necessary
to perform the following:
1. Clean the return line strainers.
2. Lubricate the Sullicon Control linkage.
3. Replace the fluid filter element.
4. Clean the control line filters.
7.5 FLUID CHANGE
Standard models are filled with Sullube. Sullube
should be changed under the following conditions,
whichever occur first:
1. Every 8000 hours.
2. Once a year.
3. As indicated by fluid analysis.
A fluid sample at every 1000 hours is recommend-
ed. For a free Sullube analysis, send fluid to:
Dow Chemical
Lubricant Technology Center
Building B-1605
Freeport, TX 77541
To facilitate this, a sample bottle is included with the
compressor.
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pressure
before doing so.
For general locations of machine components,
refer to Figures 2-1, 2-7 (TS-20), and 9-1A, 9-1B, 9-
1C, 9-2 and 9-3 (V200TS).

Change intervals may vary with alternate fluids.
Consult factory to determine change intervals for
fluids other than Sullube.
