Disconnect the flat ribbon cable from the head board (1).
Undo the screws fastening the pressure plate (3) to the head
mount and the two screws on the gantry (5).
NOTE
Only undo the fastening screws. The clamps for the flat ribbon cable
remain in place.
Remove the head board (1). This provides access to the
pneumatic distributor (2) below.
NOTE
Mark the installation position of the contact disks and spacer bolts
and take care not to lose them. These will need to be correctly
replaced later.

they are no longer installed.
