・
When the connecting rod installation position is on the inside, the measurement value is the amount of movement of the
treadle from the neutral position to the forward position and to the backward position.
・
For treadle unit -H, the point of change (F) in the forward depression force is between S1 and S2, and the point of change
(R) in the backward depression force is between S6 and S7.
