OIL SCAVENGE LINE
The oil scavenge line goes from a jet in the separator tank to a screwed fitting in the air end.
During maintenance, check the jet, valve, piping and potential oil presence in the outlet air.
During maintenance, check that the scavenge line is clean and nothing blocks the oil flow. The oil scavenge line clogging
results in increased content of compressor oil in the outlet air.

Recommended service intervals can be found in the maintenance table.
Removal
Warning
Before removing the filter, make sure the machine is stopped and pressured air has been relieved from the
system.(see paragraph Stopping the machine on page 18 ).
Clean the outer body of the filter and remove it by screwing it anticlockwise. Use a filter wrench to remove the filter.
Inspection
Check the filter insert.
Warning
If there is preservative coating, shellac or other varnish present in the filter body, compressor oil can be impaired
and the filter should be replaced immediately. See paragraph Lubrication on page 36 .
ASSEMBLY
Clean the filter bearing area.
Spread oil on the new filter gasket and screw the new filter clockwise until the new filter gasket fits in the filter bearing area.
When the gasket fits in the bearing area, tighten the filter cartridge by turning it 3/4 revolution with a filter wrench.
After the oil filter is completely reassembled, check for any oil leakage while running the machine.
Warning
Start the machine (see paragraph Before starting and Starting the machine at page 15) and check for leakage
before putting the machine back to operation.
OIL SEPARATOR INSERT
If the oil and air filters are serviced properly, the oil separator insert does not require any regular maintenance.
If it is necessary to replace the insert, follow these instructions:
