➠ Fit the elastomeric spring (item 10 in Fig. 7.5 - 3) on the new deflection unit (item 8 in Fig.
7.5 - 3
).
➠ Use the two M6 x 10 hexagon socket-head screws (item 7 in Fig. 7.5 - 3) to fix the deflection
unit (item 8 in Fig. 7.5 - 3
) to the gantry.
➠ Align the ’external’ brake (item 5 in Fig. 7.5 - 3) so that it is parallel with the braking surface and
fix to the deflection unit (item 8 in Fig. 7.5 - 3
) using the two M3 x 8 hexagon socket-head
screws.
➠ Place the toothed belt (item 9 in Fig. 7.5 - 3) around the synchronizing disk of the deflection
unit (item 8 in Fig. 7.5 - 3
).
PLEASE NOTE
See Fig. 7.5 - 4, page 7 - 24 onward, for the following assembly steps.
➠ Feed the toothed belt into the opening (item 3 in Fig. 7.5 - 4) in the tension jack (item 2 in Fig.
7.5 - 4
) so that it runs approximately 270° around the ’long’ synchronizing disk (item 4 in Fig.
7.5 - 4
).
➠ Place the tensioning key (item 5 in Fig. 7.5 - 4) on the synchronizing disk (item 4 in Fig.
7.5 - 4
).
➠ Use a size 8 Allen key to turn the synchronizing disk (item 4 in Fig. 7.5 - 4) clockwise.
➠ Screw the hexagon socket-head screw (item 7 in Fig. 7.5 - 4) into the threaded hole in the
spacer bolt (item 6 in Fig. 7.5 - 4
) and pre-tension the X-axis toothed belt.

➠ Push the head mount (item 1 in Fig. 7.5 - 4) towards X-axis motor unit as far as the stop on the
elastomeric spring.
➠ Turn the hexagon socket-head screw (item 7 in Fig. 7.5 - 4) 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 7 in Fig. 7.5 - 4) with the locknut (item 8 in Fig.
7.5 - 4
).

➠ Switch the placement system off and secure it to prevent switching on again.
DANGER POWERFUL MAGNETIC FIELD
Always follow the special safety instructions when working in the vicinity of powerful magnetic
fields.
➠ Dismantle the two tensioning keys (item 1 in Fig. 7.5 - 5) (see section 7.5.2.2)
➠ Remove the toothed belt from the two synchronizing disks (item 2 in Fig. 7.5 - 5).
➠ Unthread the toothed belt from the deflection unit (item 4 in Fig. 7.5 - 5).
➠ Remove the toothed belt from the synchronizing disk of the X-axis motor unit (item 5 in Fig.
7.5 - 5
).
