⇒ Connect gear wheels 19 and 18 with toothed belt 9, paying attention to their
marks ’MK’ which must coincide according to Fig. ’G’ (zero position).
⇒ Push shaft encoder outwards till the toothed belt is lightly tensioned and
meshing properly with the gear wheels. Lightly tighten screws 15. Recheck
marks ’MK’.
⇒ Fit screws 15a, washers 16 and locking plates 17. Apply MOLYKOTE paste G
to the threads and head seatings.
⇒ Align toothed belt exactly in running direction.
⇒ Attach spring balance 59 to the shaft encoder and slightly preload it according
to Fig. ’F’.
⇒ Loosen all screws 15 and 15a, paying attention that the shaft encoder can still
move freely.
⇒ Tension toothed belt with 30 N indicated on spring balance, and fixate shaft
encoder with screws 15 and 15a.

tion between the holder guide and screw surfaces as small as possible.
