► 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.
