Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Torque cam stamping: T1 (2)Tolerance for racks not indicated: +-0.05mm. (3)Set stop lever before governor adjustment. [When setting stop lever after governor adjustment, confirm that point I (Ra) can be obtained at full setting.] (4)Stop lever's normal position setting: equivalent to RA (5)Damper spring setting
----------
T1=AD70 Ra=R1+1mm RA=17.5mm
----------

Speed control lever angle

F:Full speed I:Idle (1)Use the hole at R = aa (2)Stopper bolt set position 'H'
----------
aa=94mm
----------
a=15deg+-5deg b=42.5deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Rack position = aa (2)Set the stopper screw. (After setting, apply red paint.) (3)Rack position = bb (speed = cc) (4)Set the stopper screw. (After setting, apply red paint.) (5)Use the hole above R = dd
----------
aa=(17.5)mm bb=1.5+-0.3mm cc=0r/min dd=35mm
----------
a=35deg+-5deg b=15deg+-5deg
