Lift the magnet cover plate (1) at the side with the long
magnetic strip and then fix the end of the cover plate to the X
gantry with adhesive tape. You can now access the long
magnetic strip.
Lever up the blue covers and loosen the 16 screws fastening
the long 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 long magnetic strip (4).
DANGER
Please take special care when working in the vicinity of the powerful
magnetic fields produced by the magnetic strip. Risk of serious
injuries through trapping limbs.
Close the magnet cover plate and fix it to the machine base.
Remove the buffer (3) from the side with the long magnetic strip
(4).
Remove the cover plate from the central cover and then the
black plastic covers on the guide rails.

Removal/Installation
NOTE: Replace the guide slides one after the other.
Undo the screws fastening the first guide slide. Please note
that the screws are of different lengths. These will need to be
correctly replaced later.
Pull the old guide slide out. Make sure that no balls can fall out.
Clean the guide screws with a lint-free cloth and a little ethanol.
NOTE:
A threading tool is integrated into the guide slide, to prevent the balls
from falling out.
Correctly position the guide slide on the guide rails. Make sure
that the lip seal runs in the rails.
Push the guide slide and while doing so, pull the threading tool
out towards the back. Make sure that no balls can fall out.
Wipe any leaking oil away with a lint-free cloth.
Loosely screw in the two upper screws and then the lower
screws. Make sure you use the correct screws (long screws for
the bottom and short ones for the top)
TIP:
Use a screw holder to help you insert the screws.
Tighten the screws crosswise with a torque wrench (9.5 N).
Install the other 3 guide slides in the same manner.
