Periodic maintenance
After the first 5 operating hours, check that cap and casing screws (Fig. E1) fit tightly.
Once per week:
Drain the condensation water by opening the tap E (Fig. E2).
Set the container in such a way that the openings of the drain tap points downward. Close the
tap as soon as only air begins streaming out. Because the compressor is lubrication free, the
condensation water can be drained into the sewer.
Once per month (or more often if the device is used in a dusty environment):
Remove the suction filter and replace it (if it is damaged) or clean the filter element (Fig. E3).
Take off the filter cap and remove the filter element.
Wash it with detergent, rinse it with water and completely dry it. Do not operate the compressor
without a suction filter.
Trouble
If the pressure on the pressure display and the manometer (Fig. E4) falls below 5.5 and the
compressor doesn't go on, check to make sure that the start switch on the pressure switch is in
the ON position.

Troubleshooting
In case of air loss proceeds as follows: (Fig. F1)
a) Charge compressor to maximum pressure.
b) Pull plug from socket.
c) With a paint brush dipped into soap water, daub all screws. Any air loss is discovered when
bubbles form.
If - with the compressor switched off - air is lost at the pressure control valve, proceed as fol-
lows:
a) Completely empty the compressed air tank.
b) Remove plug N (Fig. F1) from the 'retainer' valve.
c) Carefully clean valve base and seal, and reassemble.
Motor protection
The compressor is equipped with motor protection that automatically interrupts the current sup-
ply (Fig.F2) in the event of an overload.
In this case, switch off the current supply and wait several minutes before you reset the motor
circuit breaker and restart the machine. If the circuit breaker trips again, disconnect the power
supply and contact an authorized customer service facility.
We recommend that you let off pressure from the boiler.
a) If possible, do not disassemble fittings while tank is under pressure. Always ensure that
it is discharged.
b) While the plug is in the socket, the cover of the pressure control may not be removed.
