4.2.7.3 Removing the X-axis 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).

4.2.7.4 Installing the X-axis toothed belt
Installing the X-axis toothed belt
► Place the toothed belt around the synchronizing disk of the X-axis motor unit.
► Thread the toothed belt in at the deflection unit.
► Thread both ends of the toothed belt in through the openings on the tension jack (2), until it is run
approx. 270° around the synchronizing disks (3).
► Fit the two tensioning keys (4) (see "4.2.5 Replacing the Tensioning Keys [00329478-01, 00329485-
01]" [ ➙ 62]).
