Service Manual (internal version) SIPLACE HF and X Series 53
Installing the scale
► Insert the new scale behind the head plate.
► Attach the new scale exactly to the lay-on edge on the gantry.
► Pull part of the cover strip off the adhesive strip and place the front end of the scale on the marked
position. The scale must be positioned at the lay-on edge.
► Now pull away the cover strip "bit by bit" and firmly fix the scale (to about halfway along the gantry).
► Move the head plate so that you can fix the rest of the scale.
► Press the scale down with a soft, clean cloth.
► Carefully pull off the cover strip.
► Use ethanol to wipe the scale and remove any adhesive residues or dirt.
► Fit the incremental encoder. This procedure is described in Chapter "Replacing the X Axis Incremen
-
tal Encoder".

DANGER
Risk of fatal injuries through trapped limbs.
For safety, place a piece of foam between the X drive and the magnetic strip.
For additional safety, keep the 4 dismantling screws in place until the X drive has been removed
from the machine.
► Once the X drive is out of the vicinity of the strong magnetic field, it can be removed from
the machine. Loosen the 4 lock screws to remove it.
► Undo the remaining 12 fastening screws (1).
NOTICE!
Note the screw lengths!
Make a note of the different screw lengths. These will
need to be correctly replaced later. Mark the positions of
the individual screws.
WARNING!
Do not undo or loosen the screws on the Z axis compen
-
sation (2), which have been secured with locking varnish.
Screw in the dismantling screws in turn, so that the X
drive is evenly pushed away from the magnetic field of
the magnetic strip. The X drive is now held by the 4 lock
screws.
