Loosely fasten the read head (2) with three screws (3).
The read head must be aligned with a 0.4 mm gap to the scale.

You must also set the exact height to the scale. Align the read
head with the aid of the casting marks provided.
Tighten the fastening screws.
Reconnect to the electricity supply.
Make sure that the cables do not rub against anything. Fasten
them with cable ties.
