TO ENSURE THAT THE COMPRESSOR WORKS CORRECTLY, PERFORM THE FOLLOWING
MAINTENANCE TASKS AT REGULAR INTERVALS (CHAPTER 14).:
15.1.
Condensation drain valve
Compressors
(Fig.10)
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 (1).
Wait until condensation is fully drained from the pressure tank.
Close drain valve (1).
Compressors with air dryer
In the case of a regular operation condensate is automatically excreted via air dryer and it is entrapped in a
bottle. Take out the bottle from a holder, release cap and pour out the condensate.
15.2.
Safety valve check
(Fig.8)
When the compressor is operated for the first time, make sure that the safety valve is working properly. Turn
screw (4) of safety valve (1) several rotations to the left until the safety valve releases air. Let the safety
valve blow out for only a few seconds. Turn screw (4) to the right until it seats, closing the valve.
The safety valve must never be used for depressurizing 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.
Warning! Compressed air can be dangerous. Wear eye protection when blowing air out.
15.3.
Replacement
of the input filter and prefilter
(Fig.11)
At the lid of the compressors crankcase is an
input filter (1) and prefilter (3).
Replacing of the input filter
:
Hand pull the rubber stopper
(2).
Remove used and dirty filter.
Input new filter and set rubber stopper.
Replacing of the prefilter:
Hand pull prefilter
(3).
Replace old prefilter with new.
15.4.
Replacement of output filter in air dryer
Before beginning, reduce the air pressure in the tank to zero
and disconnect the appliance from the mains.
(Fig.12)
In the case of a regular operation of a dryer it is necessary to replace the dryer
filter in the upper part.
Remove the dryer plug (1) by unscrewing to the left from the dryer head (4).
Put in a new filter (2).
Refit the dryer plug to the dryer head (4) and tighten it to the right.
