0000001801 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Adjusting method (service voltage Vi, dummy bolt):
1. Hold the dummy bolt against the control lever when N = N1 r/min, Q = Q1 mm3/st.
Fix using the lock nut.
2. When adjusting the potentiometer, position the control lever against the dummy bolt and adjust the potentiometer so that the output voltage is V1 (V).
3. Remove the dummy bolt after the completion of adjustment.
Confirm that the potentiometer output voltage is within the standards mentioned when the control lever is idling and in full-speed position.

Adjustment of the W-CSD
1. Adjustment of the advance angle of the timer
(1)Determine the timer advance angle using the following graph.
