Replacing the tensioning keys
Installing the tensioning key, item 1 (synchronizing disk,
short)
► Place the tensioning key on the "short synchronizing
disk" (9).
► Fasten the tensioning key with the M4 x 5 hexagon
socket-head screw (8).
Installing the tensioning key, item 2 (synchronizing disk,
long)
► Use the Benzing U clip to fit the spacer bolt (7) onto
the new tensioning key.
► Place the tensioning key on the "long synchronizing
disk" (10).
► Use the size 8 Allen key to turn the synchronizing disk
slightly until the hexagon socket-head screw (3) can
be screwed in.
► Pretension the toothed belt by turning the hexagon
socket-head screw clockwise.
Replacing the tensioning keys
► Push the head mount towards the X-axis motor as far
as the stop on the elastomeric spring.
► Turn the hexagon socket-head screw 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 (3) with the
locknut (11).

4.2.6.3 Removing the deflection unit
Removing the deflection unit
► Switch the machine off and secure it to prevent unauthorized reactivation, as described in section
4.3 from page 104 onwards.
► To relax the toothed belt (9), proceed as follows:
⇨ Loosen the locknut (11),
⇨ Turn the hexagon socket-head screw (1) counterclockwise.
► Remove the M4 x 35 hexagon socket-head screw (1).
► Pull the tensioning key (2) off the synchronizing disk (3).
► Pull the toothed belt (9) out through the opening in the tension jack (4).
► Unthread the toothed belt from the deflection unit (8).
► Loosen the two M3 x 8 hexagon socket-head screws (6) and remove the Y-brake "outside" (5).
► Loosen the two M6 x 10 hexagon socket-head screws (7) and remove the deflection unit ’X’ (8).
► Remove the elastomeric spring (10) from the deflection unit.

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.
