0000001801 POTENTIOMETER ADJUSTMENT

Adjusting method [applied voltage Vi, dummy bolt (C)] 1. Hold the dummy bolt (C) against the control lever at position N = N1, Q = Q1. Fix using the lock nut. 2. When adjusting the potentiometer, position the control lever against the dummy bolt (C) and adjust the potentiometer so that the output voltage is V1 (V). 3. Remove the dummy bolt (C) after the completion of adjustment. Confirm that the potentiometer output voltage is within the above mentioned standards between the control lever's adjusting point and the idling position.
