► Carefully rub the following contact surfaces with a
dressing stone (oil stone) and wipe clean with a cloth
and ethanol.
1. Magnet support
2. Contact surfaces of the 4 guide trolleys
3. Contact edges of the 4 guide trolleys
► Enlist the help of a second strong person. Lift the
gantry up to the guide trolleys and secure the gantry
at the top with two screws (M4x14).
Insert and loosely tighten the remaining fastening
screws. Observe the correct screw lengths.
► Do not tighten the fastening screws yet!
► Lift the far end of the gantry (1) so that the gantry
rests on the contact edges of the top guide trolley (2).
► Tighten the top fastening screws.
► Then tighten all 16 fastening screws with the aid of
the special torque wrench ("Bruchsal version")
(9.5 N).
CAUTION!
If the special torque wrench is not available, make sure
that the two bottom screws on the guide trolley are not
overtightened.
► With the aid of a 1/100 plastic thickness gauge, check
the gap between the gantry contact edge and the
guide trolley (1). The gantry must lie flush with the
guide trolley, leaving no room in-between for the
thickness gauge.
► If this is not the case, dismantle the gantry and clean
the contact surfaces again thoroughly (with the dress
-
ing stone).

must be clean and free of grease.
1. Head plate - front view
2. Incremental encoder
3. 3 x fastening screws
► Loosen the three screws (3) fastening the incremen
-
tal encoder (2) of the X axis and carefully lift off the
incremental encoder.
► Temporarily fasten the incremental encoder in a suit
-
able position.

► Mark the original position (1) of the scale (2) with a
scribing iron. This ensures that the new scale can be
fixed in the exact position to the right and left end
stop.
CAUTION!
Do not damage the gantry.
Make sure that the gantry coating is not damaged.
► Carefully lever the scale upwards on one side with
the scriber and then gently extract the scale.
► Remove any adhesive residues with ethanol. The
surface to be fixed down must be clean and free of
grease.
