(1)Screw in (A) to obtain L1.
(2)Select C so that dimension L2 can be obtained.
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)Set to full boost.
(3)Screw in the aneroid compensator body to obtain the performance shown in the graph above.
(4)As there is hysterisis, measure when the absolute pressure drops.
(5)Hysterisis must not exceed rack position = h1.
