the toothed disks at the 3 adjustment
units. This would cause incorrect
alignment of the adjustment units.
Secure these positions with a suitable
tool (screw clamp etc.)
X Remove the 4 fastening screws (3) and then
lift out the stepping motor (4).
X Unplug the connection cable in the cable duct.
X Fit the new stepping motor and reconnect the
system to the electrical system.
