Oil contamination
Unlike engine oil, no cleaning agent is added to the
compressor oil. Even if the compressor is run for a
long time, the oil never becomes turbid as long as
there is nothing wrong with the compressor or its
method of use. Inspect the extracted oil for any of
the following.
• Increased opacity of the oil.
• Color change to red.
• Presence of foreign matter, metal filings, etc.
Oil check
The compressor oil must be checked as follows
when being charged into a used system.
1. Perform the oil return operation (p.16).
2. Remove one of the oil drainer plugs and drain
the oil through it. TM55 and TM65 feature three
oil drainer plugs:
• One on each side of the compressor under the
sight glasses.
• One in the front side, in between the bolts.
3. Check the oil for contamination.
4. Fill the compressor with the specified amount
of oil (p.19)
