DANGER POWERFUL MAGNETIC FIELD
Always follow the special safety instructions when working in the vicinity of powerful magnetic
fields.
➠ Loosen two M3 x 8 hexagon socket-head screws (item 2 in Fig. 7.5 - 8) to remove the incre-
mental encoder for the X-axis (item 1 in Fig. 7.5 - 8
).
➠ Loosen the eleven M2.5 x 5 hexagon socket-head screws (item 3 in Fig. 7.5 - 8) with washers.
➠ Move the head mount (item 6 in Fig. 7.5 - 8) across as far as the elastomeric spring (item 7 in
Fig. 7.5 - 8
) in order to prevent any damage to proximity switches B1 and B2 (item 5 in Fig. 7.5
- 8).
➠ Remove the scale (item 4 in Fig. 7.5 - 8).

➠ Carefully insert the scale.
CAUTION
Do not touch the incremental tracks with bare fingers.
➠ Loosely tighten the eleven M2.5 x 5 hexagon socket-head screws with washer.
➠ Push the scale along the bars as far as the stop (item A in Fig. 7.5 - 8)
➠ Tighten the M2.5 x 5 hexagon socket-head screws.
➠ Use the feeler gauge to set the 0.4 mm gap between the incremental encoder and scale.
➠ Use the two M3x8 hexagon socket-head screws (item 2 in Fig. 7.5 - 8) to fix the incremental
encoder (item 1 in Fig. 7.5 - 8
) to the X-axis.

➠ Move the x-slide against the stop on the motor side.
➠ Measure the belt tension on the side of the placement head.
➠ Center the measuring pin of the belt tension measuring device, 208 mm away from the
deflection pulley of the open ended toothed belt, as close as possible to the belt.
