Adjusting the footswitch

1. Flip the footswitch down.
2. Turn the adjusting screw (A), until (when the footswitch is in a
closed state) it audibly actuates the tab (B) of the microswitch.
3. The optimum switching point is reached when the clearance of an
engaged but not actuated footswitch is approximately 6–7 mm.

Replacing double castors

1. Remove the scanner from the holder and set it safely aside. For a
device with a trackball, remove the trackball from the spherical
recess.
2. Carefully turn the device over onto a soft foam base onto the
service cover. In this process, hold on to the monitor tightly so that it
does not tilt to the side uncontrollably.
3. Remove the defective double castor with an open-end wrench (SW
17).
4. Screw the new double castor on tight.
