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.
