TO ENSURE THAT THE COMPRESSOR WORKS CORRECTLY, PERFORM THE FOLLOWING
MAINTENANCE TASKS AT REGULAR INTERVALS:
Cover removal:
Unscrew the 4 screws from the front cover
Disconnect the grounding wire
Remove the front cover
Reassemble using the opposite order
18.2. Condensation drain valve
(Fig.1)
From air tank
During regular use, release condensation from the pressure tank. Switch off the compressor at the
mains. Reduce air pressure in the appliance to max. 1 bar by releasing air via a connected device.
Place the vessel under release valve and open the drain valve (8). Wait until condensation is fully
drained from the pressure tank. Close drain valve (8).
Monitor the level in the vessel using the 1 l or 2 l markings (depending on the
volume of the vessel), and empty at least once a day. The vessel may overflow if
the condensate is not drained out of the vessel at the defined interval.
Risk of slipping on a wet floor in case of the collecting bottle overflow.
18.3. Safety valve check
When the compressor is operated for the first time, make
sure that the safety valve is working properly. Let the safety
valve blow out for only a few seconds.
Carefully and slowly open the drain valve. Quickly opening the drain valve is
accompanied by a loud sound and uncontrollable stream of accumulated
condensate.
Never use the safety valve to vent air pressure in the air tank. It could damage the
safety valve. The valve is set to the maximum permitted pressure by the
manufacturer. Adjustments are not permitted!

DAMAGE TO THE EYES! RISK OF DAMAGE TO THE EYES.
