3-7. Tension release mechanism (1)
1. Install the tension release solenoid (1) to the solenoid holder (3) with the two screws (2).
2. Pass the tension release solenoid link (4) through the tension release rubber assembly (5) and the plate (6) as
shown in the illustration, and then install it to the plunger (8) with the plunger pin (7).
3. Install the spring (9) to the plunger (8).
4. Insert the plunger (8) into the tension release solenoid (1), and then install the plate (6) to the solenoid holder
(3) with the bolt (10) and the washer (11) so that the dimension A is 13.7 mm.
5. Insert the tension release link (12) into the arm from the face plate side, and install it with the shoulder screw
(13).
6. Provisionally install the tension release solenoid assembly (14) with the two screws (15).
7. Connect the tension release solenoid assembly (14) and the tension release link (12) with the shoulder screw
(16).
8. Adjust the position of the tension release solenoid assembly (14) using a gauge so that the tension release link
(12) protrudes from the edge of the tension stud bracket assembly (17) on the arm by 19.2 ± 0.2 mm, and then
tighten the two screws (15).
9. Insert the tension release pin (18) into the tension stud bracket assembly (17), and then insert it into the arm.
10.Tension the set screw (19) so that the tension discs are open by 0.5 to 1.0 mm when the tension release link
(12) is pushed in the direction of the arrow B.
* If not using a gauge, insert the tension release pin (18) into the tension stud bracket assembly (17), and insert it
into the arm, and then tighten the set screw (19) at almost the center of the screw stop on the tension stud
bracket assembly (17).
With the tension release link (12) pushed in the direction of the arrow B (Figure C), move the tension release
solenoid assembly (14) so that the tension discs are open by 0.5 to 1.0 mm, and then tighten the two screws
(15).
