2.3.2 Loading arm assemblies (supply, take up)
(1) Attach the loading arm assembly (supply) and loading arm
assembly (take up) so that the alignment markings on
their gears face each other and the holes on their arms
are respectively aligned with the holes on the main deck.
(2) Attach the guide rail, attach the pole base assemblies onto
the extremities of the arms, then perform the unloading
operation so that the pole base assemblies come to the
most forward positions.
Note:
• When attaching the pole base assemblies (supply/take
up), temporarily tighten the 3 screws other than the 2
screws on the sides of the guide rail extremities so that
the parts do not slip out.
(3) Attach the surrounding parts of the guide rail.

2.3.3 Rotary encoder, change lever assembly, control cam
(1) To attach the rotary encoder, align the triangular align-
ment markings and push the rotary encoder in until the
claws are locked.
(2) To attach the change lever assembly, align its holes with
the holes on the mechanism assembly. As the change
lever assembly is projected on the rear side of the mecha-
nism assembly, take care that the assemblies are not
separated from each other.
(3) To attach the control cam, align its holes with the holes
on the mechanism assembly by pushing the capstan
brake assembly downward.

of the mechanism assembly, attach the slide plate so that
its alignment holes are aligned with the holes of the
mechanism assembly.
