Use the long Allen wrench (no ball head) to loosen the grub
screw (4) on the read head (2). The grub screw applies
pressure to the head mount and prevents unwanted movement
of the read head.
Remove the grub screw (4) and apply a little locking varnish
(Loctite No. 243) to it.
Screw the grub screw back in (4) until you are almost at the end
of the thread.
Install the read head (2) with the three fastening screws (3) so
that there is a gap of 0.4 mm between the read head and the
scale. Use the corresponding thickness gauge (plastic).
Tighten the grub screw (4) until you feel a slight resistance (not
too tight).
The read head is now fastened correctly.
