CAUTION
Make sure that the cables are firmly seated. Otherwise, the high acceleration forces may
cause the cable to slip out of position and shear through.
➠ Turn the hexagon socket-head screw (item 2 in Fig. 7.5 - 7) to pre-tension the X-axis toothed
belt.
➠ Use the three M6 x 8 hexagon socket-head screws to fit the black cover strip to the cross-beam
above the gantry concerned.
➠ Connect the cable of the fan motor to the socket.

➠ Push the head mount (item 1 in Fig. 7.5 - 7) towards X-axis motor unit as far as the stop on the
elastomeric spring.
➠ Turn the hexagon socket-head screw (item 2 in Fig. 7.5 - 7) to set the belt tension to 53 Hz +
1/-3 Hz.
CAUTION
Do not overstretch the toothed belt when adjusting the belt tension.
➠ Secure the hexagon socket-head screw (item 2 in Fig. 7.5 - 7) with the locknut (item 8 in Fig.
7.5 - 7
).

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.
