Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Tolerance for racks not indicated: +-0.05mm. (2)Set idle at point K (N = N1, R = R1) and confirm that the injection quantity does not exceed Q1 at point J (N = N2). (3)Boost compensator cancel stroke: BSL (4)RACK LIMIT (5)Boost compensator stroke: BCL (6)Damper spring setting (7)Rack difference between N = N3 and N = N4 (8)Variable speed specification: idling adjustment

Speed control lever angle

F:Full speed I:Idle (1)Set the pump speed at aa (2)Set the pump speed at bb. (3)Use the hole above R = cc (4)Stopper bolt setting (5)Stopper bolt setting

2-stage changeover lever adjustment (A) Speed lever (B) Load lever (C) 2-stage changeover lever (D) Link (E) Bolt (G) Variable speed specifications (H) Minimum maximum speed specifications F:Full speed I:Idle 1. Minimum-maximum speed specification adjustment (when running) (1)After completing governor adjustment, hold the 2-stage changeover lever (C) so that the speed lever (A) contacts the full speed stopper. (2)In this condition, the load lever is held in the idle position. (3)Adjust bolt (E) so that the clearance between the pin underneath lever (C) and the end of the long groove in link (D) is L. (4)Lock using the nut. 2. Variable speed specification adjustment (at operation) (1)Hold the 2-stage changeover lever (C) so that the load lever (B) contacts the full load stopper. (When the load lever is equipped with a cancel mechanism, move it so that it contacts the stopper without canceling.) (2)In this condition, confirm that the speed lever (A) moves from idle to full speed.
