Remove the magnet cover (1). You might need to enlist the help
of a second person.
Lift both sides of the cover plate at the same time.
Pull it out on one side, until it reaches the groove between two
magnet plates.
Insert the notch of the shorter end into the groove on the
magnetic strip (2).
Move the gantry over this groove, until the cover plate is
accessible and can be removed.
Remove the buffer (3) from the side with the large magnetic
strip (4).
Lever off the blue covers and undo the 16 screws fastening the
magnetic strip (4).
NOTE
If the blue cover is damaged (kinks, cracks etc.), replace it during
reinstallation. White or pale patches in the plastic indicate areas of
damage.
Remove the magnetic strip (4) and push the gantry outside the
magnetic strips's area of influence.
