(3) Install the control plate so that the section A of the loading
arm gear shaft fits into the hole (A) of the control plate, the
section B of the control plate guide into the hole (B), and
the control plate comes under the section C of the rotary
encoder guide and the section D of the loading arm gear
shaft while press-fit the pole base assmebly (supply side)
as indicated by the arrow. It is important that the tension
arm assembly shaft is positioned closer toward you than
the control plate. (See Fig.3-2-15c.)
(4) Make sure that the mark E of the control plate is in align-
ment with the mark
Fig.3-2-15c.)
(5) Pull off the hexagonal wrench for positioning.

3.2.16.1 How to remove
(1) Remove the loading arm gear (supply side) by loosening
the screw (A). (See Fig. 3-2-16a.)
(2) Remove the screw (B) and remove the torsion arm from the
pole base assembly (take-up side). (See Fig.3-2-16a.)

(3) Turn the loading arm gear (take-up side) clockwise so that
the notch of the loading arm gear (take-up side) is in align-
ment with the projection of the loading arm gear shaft and
lift it.
Likewise, turn the loading arm counterclockwise so that the
notch is in alignment with the projection and remove the
loading arm gear (take-up side). (See Fig.3-2-16a and Fig.
3-2-16b.)
(4) When removing the loading arm gear shaft, be sure of first
removing the screw retaining the drum assembly (on the
back side of the loading arm gear shaft). Then remove the
screw (C) and remove the loading arm gear shaft by sliding
it.

3.2.16.2 How to install
(1) Align the notch of the loading arm gear (take-up side) to the
projection B of the loading arm gear shaft and slip it over.
Then rotate it clockwise for alignment with the projection A
and slip it down to the bottom. (See Fig.3-2-16b.)
(2) Then turn the loading arm gear (take-up side) counter-
clockwise. Hang the torsion arm on the pole base assem-
bly (take-up side) and tighten the screw (B).
(3) Install the loading arm gear (supply side) so that the guide
mark of the loading arm gear (take-up side) is in alignment
with the guide mark of the loading arm gear (supply side).
Then hang the torsion arm on the pole base assembly
(supply side) and tighten the screw (A). (See Fig.3-2-16a.)
