Compressor, air/oil reservoir, separation chamber and all piping and tubing
may be at high temperature during and after operation.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the "FULL" marker.
LUBRICANT CHANGE PROCEDURE - Upgrading to a longer life lubricant is essentially a very
worthwhile practice. Following are the primary steps to be completed when upgrading or changing the
type of lubricant.
1. Thoroughly drain system:
- Drain oil from air end and cooler while hot.
- Break low point connections and drain oil from pipe runs.
- Dump oil from the filter and reinstall used filter.
2. Fill the system with a 50 percent charge of the new lubricant:
- Start the machine and stay there to observe.
- Allow the machine to run about five minutes at temperature, or until temperature stabilizes, then
shut down.
3. Thoroughly drain the machine.
4. Change to a new filter and separator.
5. Fill the system with a full charge of the new lubricant, then reinstall drain plug.
6. Machine should then be run normally, however, total run time after the initial changeout should be 50
percent of normal anticipated service life of the new lubricant.
- Drain all lubricant from the system, change the filter and separator, and replace with a full charge of
the new lubricant.
7. Subsequent lubricant changeouts should be at normal intervals. (See "Oil Change Interval" Figure 5-
7, page 49.)
