2. Attachment procedure
1) Apply grease to the GL drive arm J portion and mechanism
chassis block.
Amount of grease: a ball of grease of 1.0 mm diameter
(Refer to "Points to be noted" on the next page)
2) Move the brake driving arm portion of the TG2 cam plate assy
clockwise. (Fig. 1)
3) Rotate the T reel table assy clockwise so that the brake (T)
block assy be placed at the position as shown in the figure 2.
(Fig. 2)
4) Move the TG2 arm block to the inner side. (Fig. 3)
5) Hold the cam groove of the GL driving arm with tweezers
through LS chassis hole K and pick it up.
6) Insert the GL drive shaft into the cam groove of the raised GL
drive arm using the trace mark of caulking on the side of the S
reel of the LS chassis block assy 3. (Fig. 4)
7) Align the pins E, F and G with the grooves.
8) Align the left side S1 screw hole and S2 shaft with the goove
H of the LS chassis block assy.
9) Move the LS chassis block assy in the direction of the arrow
I so that the YJ position is obtained.
YJ position: The position where gooseneck gear can be
installed. (Ref. 1-3-16)
10) Align the claw A and install the FP-826 flexible board 2 in
the mechanism chassis block assy.
11) Connect the soldering at the eight locations 1 and install the
