and plugs (2) do not touch the casing. This prevents
the cables being damaged during movement.
► Fix the return unit (1) with the grub screw (3) to the
mount (4).

Removal
► Remove the P&P head from the machine.
► Loosen the two screws (4) fastening the mount at the
side.
► Remove the cable ties and unplug the press-fit con-
nection (3).
► Unthread the cable as far as the head board (5).
► Loosen the screws (2) fastening the incremental en-
coder (1).
► Unplug the press-fit connection (3) and extract the in-
cremental encoder (2).
CAUTION! Do not damage the incremental
scale!
The Z axis scale is situated under the incremental encod-
er.
► Fit the new incremental encoder so that there is a gap
of 0.4 mm between it and the scale. Use the corre-
sponding thickness gauge (plastic).
► Make sure that the mount and the incremental encod-
er are installed parallel to one another. Where neces-
sary, correct the play at the holes (within the
tolerance) and tighten the screws.
► Check the track signals.
