1. Stopper bolt A adjusting method
(1)When the air cylinder pressure is P1, confirm that there is a clearance between the stopper bolt (A) and the lever (a).
(2)Then, screw in the stopper bolt A and temporarily set where it contacts the stop lever a.
(3)Apply P2 to the air cylinder.
(4)Confirm that the speed lever (c) operates between idling and full speed positions.
(5)Fix the stopper bolt A using nut d.
2. Stopper bolt <B> adjustment method.
(1)At air cylinder pressure P1, pump speed N1 and rack position is Ra, adjust stopper bolt (B) so that the speed lever (c) is in the stop position.
(2)Move the lever a several times and then fix the stopper bolt B using the nut e.
(3)Nut d tightening torque: T1
