Check the oil level in the oil inspection glass once a week while the compressor is switched off and
top up with oil if necessary (see "Filling oil").
Switch on the compressor for this purpose and remove the air filter from the suction spout or motor
hood opening (depending on the type used). Then fill with the required quantity of oil. Check the oil
level again in the inspection glass. Insert the air filter in the respective opening subsequent to this.
Monthly
Carry out visual inspection
Carry out a visual inspection of the unit once a month. Ensure in particular that no connections or
screws have loosened and examine the general condition of pressure hoses.
Draining condensate water from the tank (Illustration 3)
Note: Condensate emerging from the unit should be removed with a suitable medium (e.g.
a cloth).
Drain condensate water from the tank once a month by releasing the drainage screw. The tank should
be under pressure during this procedure.
Open the drainage cock once for this purpose. This is fitted above or below the tank (depending on
the type used). The tube supplied should be used for draining condensate water where the drainage
cock is mounted above the tank.
Draining water from the water separator (Illustration 4)
Note: Condensate emerging from the unit should be removed with a suitable medium (e.g.
a cloth).
Condensate water should be drained from the water separator once a month (or more often if neces-
sary).
Turn the knob in a clockwise direction for this purpose, push it in, holding it depressed until the water
has drained out. Turn the knob in an anticlockwise direction after the water has been drained off. The
tank should be under pressure during this procedure.
Quarterly or every 6 months
Removing the filter (illustration 5)
Remove the filter and clean it in a suitable cleaning agent (e.g. washing-up liquid).
