➠ 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
).
