Oil Analysis
Oil analysis is an excellent tool to add to your compressor maintenance program. At regular
intervals you submit lubricant samples to a qualified laboratory. From this you receive a
detailed report showing the lubricant condition, wear metals, and contaminants. The rate that
these measurements change over time provides the basis for predictive compressor
maintenance. Saving you from unplanned machine downtime and unnecessary oil changes.
DA GER
Hot oil under pressure will cause severe injury, death, or property damage.
Be sure the compressor is shutdown and pressure relieved before attempting to
remove the oil filter, separator, oil fill, or change the oil.
Checking Oil Level and Adding Compressor Oil
1. Switch off the unit, disconnect the power, and lockout and tag to prevent accidental
restarting.
2. Allow one minute after stopping the compressor for settling and the pressure to relieve.
3. Remove any dirt from around the fill cap, and then remove the fill cap.
4. Inspect the cap for damage and cleanliness. Replace if necessary.
5. The oil should be:
- Visible in the sight class for the SE20-SE30.
- Arrow in the green section of the gauge placed on the separator tank for the
SE40-SE50.
6. Replace the cap securely. Never put the cap on without tightening it immediately.
Changing Compressor Lubricant
1. Switch off the unit, disconnect the power, and lockout and tag to prevent accidental
restarting.
2. Allow one minute after stopping the compressor for settling and the pressure to relieve.
3. Remove any dirt from around the fill cap, then remove the fill cap. If the lubricant
appears dirty or has a foul smell it should be replaced.
4. Drain the lubricant from the bottom of the air/oil receiver. Oil will drain more quickly
and completely if it is warm from operation.
5. Close all drains and replace with fresh compressor oil to the proper level.
6. Replace the fill cap and run the unit.
7. Switch off the unit and disconnect the power to prevent accidental restarting.
8. Allow one minute after stopping the compressor for settling and the pressure to relieve.
9. Remove the fill cap to see if more lubricant should be added and to insure that there are
no leaks.
