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.
Remove the hoses from the pneumatic distributor (2).
WARNING
Risk of injury to hands. Press the lock in with a suitable tool and
extract the hose out with hose pliers.
TIP
Cut the hoses with wire cutters and then dismantle the
pneumatic distributor. It is easier to disconnect the hoses when
they are no longer installed.
