TROUBLESHOOTING GUIDE FOR UNITS IN SERVICE FOR A PERIOD OF TIME (CONTINUED)
Symptom
Oil in discharge air
Possible Cause(s)
1. Restricted intake filter
2. Wrong type of oil
3. Worn rings or scored cylinder
4. Compressor running hot
Corrective Action
1. The filter should be changed frequently to avoid
possible problems and to make the compressor
operation efficient. There is a vacuum created in
the intake of the compressor, which causes high oil
consumption by pulling oil through the rings. There
is also a chance of the intake filter media being
destroyed, allowing contaminants to enter the
intake and cause wear problems
2. Do not use SAE-30 automotive type oil. Using the
wrong oil can cause various problems with the
pump and will void the warranty. Only use the oils
that the operating manual recommends
3. Replace rings and/or replace cylinder
4. Make sure compressor is running the correct
rotation. Compressor should be clean and in a well
ventilated area. Oil should be changed on regular
intervals according to the specifications listed in the
manual.
Air filter must be changed as it gets dirty
