3-16 Adjusting the position of the touch-back switch

The height of the touch-back switch can be changed by turning push button (1). When you desire to further

change the position, loosen setscrew (2) to slide it up or down, or loosen setscrew (3) to move it up or down

together with switch base (4).

In addition, tightening torque of setscrew (2) should be moderate since the screw is tightened in the plastic base.

And, securely and strongly tighten setscrew (3).

When removing the handwheel, be sure to check the following matters for adjustment.

1) Provide a clearance of 1 mm between handwheel

(1) and the pulley cover. If the clearance is too narrow,

the position detector solenoid comes in contact with

the synchronizer. If it is too wide, defective detection

may occur.

2) Be sure to adjust screw No. 1 in the handwheel to

the flat section of the motor shaft, and tighten the

screws in the order of No. 1 and No. 2.
