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) (5) and stop the compressor. Wait until
the pressure is released through the automatic
blow-down valve. Unscrew the oil filler plug (2)
by a single 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. Drain plugs are fitted at the air
receiver (DPar) and compressor element (DPcv,
DPosv). Catch the oil in a drain pan. Unscrew the
filler plug to speed up draining. After draining,
reposition and tighten the drain plugs.
3. Remove the oil filters (3), 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 (4) 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. Run the unit unloaded for a few minutes to
circulate the oil and evacuate the air trapped in the
oil system.
7. Stop the compressor. Let the oil settle for a few
minutes. Check that the pressure is released by
opening an air outlet valve (5). Unscrew filler
plug (2) and add oil until the pointer of the oil
level gauge (4) again registers in the upper
extremity of the green range. Reinstall and tighten
the filler plug.
In this case, contact Atlas Copco.

Never add more oil. Overfilling results in
oil consumption.
