The quality and the temperature of the oil determine the oil change
interval.
The prescribed interval (see section 1.2 ) is based on an oil temperature
of up to 100 °C and normal operating conditions.
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)
one turn. This uncovers a vent hole, which permits any pressure
in the system to escape.
2. Drain the oil by removing all relevant drain plugs. Drain plugs
are located at the air receiver, compressor element and
compressor oil cooler. Catch the oil in a drain pan. Screw out the
filler plug to speed up draining. Tighten the plugs after draining.
3. Remove the oil filter (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)
registers in the upper extremity of the green range. Take care that
no dirt drops into the system. Reinstall and tighten the filler plug.
6. Run the unit at no load for a few minutes to circulate the oil and
to 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).
Screw out 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.

Keep the coolers (1) and (2) clean to maintain the cooling efficiency.
Then clean by air jet in reverse direction of normal flow.
Steam cleaning in combination with a cleansing agent may be
applied.
