Removal
X Switch off the machine and secure it to prevent unauthorized reactivation.
X Move the gantry in the PCB transport direction and position it so that the permanent magnets can be
removed:
Gantry 1 via the permanent magnets (1C)
Gantry 2 via the permanent magnets (2C)
Gantry 3 via the permanent magnets (2C)
Gantry 4 via the permanent magnets (1C)
X Remove the black cover strips on the crossbeam above the gantry concerned (3 M6 x 8 hexagon
socket-head screws).
DANGER: POWERFUL MAGNETIC FIELD
Always follow the special safety instructions when working in the vicinity of powerful magnetic
fields.

X Remove the permanent magnets from the gantry concerned:
X Remove the magnet cover plate as follows:
Lift both sides of the cover plate at the same time.
Pull it out towards one side, until it reaches the gantry.
Insert the notch of the shorter end into the groove between the magnetic strips.
Move the gantry over this groove, until the cover plate can be removed.
X Carefully remove the blue covers e.g. with a screwdriver.
X Loosen the 4 (1A or 2D) or 16 (all others) M6x12 hexagon socket-head screws, fastening the
permanent magnets.

CAUTION:
Permanent magnets
When permanent magnets are placed on a magnetic surface (e.g. iron, nickel or steel), be
extremely careful not to catch your hands or fingers between the surface and the permanent
magnet.
X If you do, you will not be able to lift the magnet from the surface on your own.

Removing the primary part of the linear motor
X Fit the X axis motor unit as described in section (4.1.4.5 Replacing the X Motor Unit [00333167-03]
J
86 ) .
X Fit the permanent magnets (4 or 16 M6 x 12
hexagon socket-head screws). The space at
the bottom must be 0.8 mm. Use the
appropriate feeler gauge or plastic strip to help
you. A gap of approx. 0.8 mm should be
between the magnet plates.
X Fit the cover strips on the crossbeam above
the gantry concerned (3 M6 x 8 hexagon
socket-head screws).
CAUTION: Precondition
You must at least remove the magnetic strip behind the linear motor (see section (4.1.4.3 Re-
placing the Y Linear Motor - Secondary Part
J
80 ) ).
