COMPRESSOR OIL AND OIL FILTER CHANGE
The quality and the temperature of the oil determine
the oil change interval.
The prescribed interval is based on normal operating
conditions and an oil temperature of up to 100 °C
(212 °F) (see section
Preventive maintenance
schedule
).
When operating in high ambient temperatures, in very
dusty or high humidity conditions, it is recommended
to change the oil more frequently.
1. Run the compressor until warm. Close the outlet
valve(s) (3) and stop the compressor. Wait until
the pressure is released through the automatic
blow-down valve. Unscrew the oil filler plug (2)
one turn. This uncovers a vent hole, which permits
any pressure in the system to escape.
2. Drain the compressor oil by removing all relevant
drain plugs (4). Catch the oil in a drain pan.
Unscrew the filler plug (2) to speed up draining.
After draining, reposition and tighten the drain
plugs (4).
3. Remove the oil filters (1), e.g. by means of a
special tool. Catch the oil in a drain pan.
4. Clean the filter seat on the manifold, taking care
that no dirt drops into the system. Oil the gasket of
the new filter element. Screw it into place until the
gasket contacts its seat, then tighten one half turn
only.
5. Fill the air receiver until the pointer of the oil level
gauge is in the upper part of the green area. Be
sure that no dirt gets into the system. Reinstall and
tighten the filler plug.
6. Start the compressor and let it run unloaded for a
few minutes.
7. Stop the compressor, wait a few minutes and top
up with oil until the pointer of the oil level gauge
is in the upper part of the green area.
In this case, contact Atlas Copco.

Never add more oil. Overfilling results in
oil consumption.
