4.12.5 Installing the primary part of the linear motor
Æ Fit scotch tape on the lower edge of the primary part of the linear motor to prevent the lockrails
from dropping.
Æ Push in the primary part from the side.

part (item 2 in Fig. 4.12 - 3
) to the motor bracket (item 4 in Fig. 4.12 - 3).

Æ Fit the black cover strips on the cross-beam above the gantry concerned (3 M6 x 8 hexagon
socket-head screws).
