In order to take out the valve balls [23], unscrew the
valve ball stop [22] from the housing [11].
ATTENTION! The stoppers are tightened with a small
amount of glue. If unscrewing is difficult, heat up
slightly the housing to loosen the glue. Make sure the
allen key used is of good quality not to damage the
stopper socket.

Push out the shaft [16] from the centre block [12] and
unscrew the second diaphragm [15].

If the shaft sealing [36] seems to be worn (internal
leakage of air is present), remove them together with
their back-up O-rings [47] by means of a pointing tool.
ATTENTION! Take extra care when carrying out of this
operation. If any scratches are made on the inner
surface of the centre body air leakage will occur. During
this operation, the sealing and O-rings usually get
destroyed so make sure you have spare parts at hand.

Using pliers remove both circlips [27] from the centre
block [12].
ATTENTION! While doing this, cover yourself with
your other hand, as the circlip easily flips away.

Press out the air valve [61] by means of a pressing
device. Be careful not to damage the brass edges of the
air valve.
The pump is now completely disassembled. Check all components for wear or damage and
replace if necessary.
When air valve is removed from the centre body check the external O-rings (6 x pos. 30)
condition and replace if necessary.
