Assembly
1 Attach each GL helical torsion spring to the GL gear. To
distinguish the S side from the T side when the opening of the
spring tip is facing toward the front, note that the coil tip of the
S side is located on the left and that of the T side is located on
the right.
[T side]
Fit the tip of the spring into the small cut-out of the GL gear.
2 Hook the tip of the spring on the bent portion of the GL arm
assembly and push the bent portion of the GL arm into the
large cut-out of the GL gear while rotating the GL gear in the
direction of the arrow.
When the bent portion of the GL arm comes
inside this range, push the bent portion into the gear.
