13-3 SPRING STRENGTH ADJUSTMENT AND SPRING REPLACEMENT
Spring strength can be adjusted in three stages according to the position of the shift bracket. At a position close to
the spring, the spring is weak (high level of difficulty). The farther the shift bracket is from the spring, the stronger
becomes the spring (low level of difficulty). In addition, slight adjustments can be made with the POWER setting.
(See Section 11-2.)

1. Grasp the knob of the slide spring to loosen the connection with the shift bracket so that the spring can be moved
to the right or left. Move the spring to the desired position.
2. Move the slide spring on the opposite side to the same
position. (Establishes uniform strength on the right
and left.)
When arm size has been replaced, even if the spring position on the shift bracket is the same, the arm gripping force
(level of difficulty) will change.
The figure below shows arms of equivalent gripping force. Use it as a guide for setting level of difficulty.
Example) If the spring is at the rightmost position in the shift bracket when arm L is attached, and if the spring is at
the leftmost position in the shift bracket when arm S is attached, arm gripping forces will be approximately equal.
