(Refer to Fig. 18)
a) Change position of suspended spring (a).
b) Loosen screws (b) and (c) and adjust the
vertical position of spring suspension metal (d).
c) Loosen screws (e) and (f) and adjust the
horizontal position of brake band suspension
metal (g).
d) Only the left side is shown in Fig. 18, but the
right side must be adjusted in the same way.
NOTE: In making brake tension adjustment, at all
modes except stop mode, confirm that the
brake band completely separates from the
cloth tape on the brake drum. (Refer to
