1. Aneroid compensator unit adjustment
(1)Select the push rod 2 to obtain L2.
(2)Screw in (A) to obtain L1.
2. Adjustment when mounting the governor.
(1)Set the speed of the pump to N1 r/min and fix the control lever at the full set position.
(2)Screw in the aneroid compensator to obtain the performance shown in the graph above.
(3)As there is hysterisis, measure when the absolute pressure drops.
(4)Hysterisis must not exceed rack position = h1.

1. Instructions for adjusting the boost compensator with the aneroid compensator
(1)Select a pushrod to obtain L1 at full boost.
(2)Remove the aneroid compensator main body.
(3)Adjust the booster compensator stroke by turning the screw at (D.
(4)Adjust the beginning of boost compensator operation by turning the notch at (H).
(5)Install the aneroid compensator at full boost state.
(6)Turn (B)'s set screw so that the distance between the snapring and the body is L2.
(7)Screw in the aneroid compensator main body and adjust the point where it comes into play.
