Replacing the deflection unit
► Fit the elastomeric spring (10) on the new deflection
unit (8).
► Fix the deflection unit (8) to the gantry, with the two
M6 x 10 hexagon socket-head screws (7).
► Align the brake "outside" (5) so that it is parallel with
the braking surface and fix it to the deflection unit (8)
with the two M3 x 8 hexagon socket-head screws.
► Run the toothed belt (9) around the synchronizing
disk of the deflection unit (8).

► Insert the toothed belt through the opening (3) in the
tension jack (2) until the toothed belt is run approx.
270° around the "long synchronizing disk" (4).
► Place the tensioning key (5) onto the synchronizing
disk (4).
► Use a size 8 Allen key to turn the synchronizing disk
(4) clockwise.
► Turn the hexagon socket-head screw (7) into the drill-
ing provided for the spacer bolt (6) and pretension the
X toothed belt.

Removing the X-axis toothed belt
► Switch the machine off and secure it to prevent unauthorized reactivation as described in "4.2.1
Preparations for Service Work" [ ➙ 60].
► Remove both tensioning keys (1) (see "4.2.5 Replacing the Tensioning Keys [00329478-01,
00329485-01]" [ ➙ 62]).
► Pull the toothed belt (2) off the two synchronizing disks.
► Unthread the toothed belt from the deflection unit (4).
► Pull the toothed belt off the synchronizing disk of the X motor unit (5).
Fitting the toothed belt on the tension jack
► Push the head mount (1) towards the X axis motor
unit, as far as the stop on the elastomeric spring.
► Turn the hexagon socket-head screw (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 (7) with the
locknut (8).
DANGER
POWERFUL MAGNETIC FIELD
Always follow the special safety instructions when working in the vicinity of powerful magnetic
fields (see section).
