Unscrew the remaining 12 fastening screws (1).
CAUTION
The screws are of different lengths. These will need to be correctly
replaced later. To make sure there are no mistakes, mark the
positions of the screws.
CAUTION
Do not loosen or unscrew the screws secured with loctite on the Z-
axis compensation (2).
Tighten the forcing screws alternately so that the X-drive is
evenly pushed away from the magnetic field of the magnetic
strip. The X-drive is held by the 4 locking screws.
DANGER
Risk of serious or fatal injuries through trapping limbs.
Place a foam mat between the X-drive and the magnetic strip for
your own safety.
For additional safety, leave the forcing screws in place until the X-
drive has been removed from the machine.
Once the X-drive has left the strong magnetic field, it can be
taken out of the machine. To do this, remove the 4 locking
screws.
