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)Excess fuel setting for starting: SXL (4)Damper spring setting
----------
N1=325r/min R1=3.8mm N2=1100r/min Q1=3mm3/st SXL=9.45+-0.1mm
----------

Speed control lever angle

F:Full speed
