0000001501 POTENTIO METER

Test data 101491-9801
(A) : Governor plan view (B): Potentiometer harness terminal (C): Potentiometer connection diagram (D) : Output voltage standard value (S): Voltage P/M: potentiometer (v): output voltage (V) (p): direction of potentiometer rotation 1. Adjustment procedures (1)Apply DCV1 to potentiometer harness terminal (B) to obtain the specified output voltage. (2)Fix the speed lever at the full side. (3)Loosen the bolt (S), and move the potentiometer from left and right. (4)Adjust so that the output voltage at full is within the standard values. (5)Fix bolt (S). (6)Repeatedly move the speed lever from the full side to the idle side. (7)Check that it is within the standard values at full and idle.
