(I) Part number of the control unit
(G) Apply red paint.
(H): End surface of the pump
1. Rack sensor adjustment (-0620)
(1)Fix the speed control lever at the full position
(2)Set the speed to N1 r/min.
(If the boost compensator is provided, apply boost pressure.)
(3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01.
(4)At that time, rack position must be Ra.
(5)Apply G at two places.

1. Air cylinder adjustment
(1)With the load lever in the idle position, temporarily set the distance between the load lever A and the air cylinder D at approximately L.
(2)Set N1 and apply P1 to the air cylinder D.
(3)Adjust set bolt (D) to obtain R1 at the same speed.
(4)Lock using nut C.
(5)Apply positive pressure several times.
(6)Confirm that the load lever A returns to the idling position N2 at pressure P2.
(7)Also at P1 confirm R1 (N1).
