HARDER & STEENBECK 20A Mode D'emploi page 14

Note: our compressors are fitted by us with one or more quick-action couplings (nom. dia-
meter 5.0 mm). We recommend use of a plug-in nipple (nom. diameter 5.0 mm) for
connecting an air hose.
Fill oil for EURO-TEC 20A, 30A and Aero-pro HTC 20A, 25A and 30A models (photos on Page 52).
Warning: use only original SINCOM/32E compressor oil (Art. No. 132010).
1. Remove the plastic hose from the filling tube (depending on the model used).
Please also heed the red DIN A4 sheet if it is included in the delivery (Fig. 1).
2. Screw the filling nozzle provided onto the open oil bottle and cut the tip off the
nozzle. Push the transparent plastic hose provided onto the filling nozzle.
3. Remove the covering cap from the filling spout (Fig. 3).
4. Fill the oil by inserting the oil bottle with the transparent hose into the filling tube
(Fig. 4).
5. Check the oil level in the inspection glass after approx. 2/3 of the bottle contents
have been filled (Fig. 5).
6. Repeat the procedure if the correct oil level has not been reached.
7. On completion of oil filling, push the black plastic hose provided onto the filling tube
again (Fig. 7).
Warning: the oil level should not exceed the maximum indicated. Excess oil should be drained
where the oil level is exceeded (see "Draining oil").
Use only original compressor oil to fill the unit, as a failure to do so will render the
guarantee null and void.
Note: retain the remaining oil for future filling operations.
8. Push the air filter provided onto the filling spout (Fig. 8) or into the motor hood ope-
ning (depending on the model used).
9. The unit should only now be connected to a suitable electrical power supply. Activate
the compressor by turning the on/off switch to position I ("ON").
The compressor is now ready for operation and should remain in a horizontal position. Oil can pene-
trate the compression chambers and damage these if the unit is tilted.
Drain the oil (see Fig. 2, Page 51).
If the compressor is filled with too much oil the oil should be drained.
1. Remove the motor from the tank if necessary.
2. Remove the motor hood. Loosen the motor hood clamp for this purpose.
3. Tilt the motor unit (but never upend it abruptly) and hold the motor block firmly with
your free hand.
4. Only tilt the housing far enough to allow the oil to flow out.
5. Check the condition of the O-ring on the motor housing hood.
6. Place the hood on the housing, ensuring that the O-ring is positioned correctly to
guarantee a 100% seal.
7. Fit the clamp on the motor hood again.
8. Mount the motor unit on the tank again and secure in position.
