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 R1 (5)Damper spring setting
----------
T1=AC70 Ra=R1+1.9mm R1=18mm
----------

Speed control lever angle

F:Full speed I:Idle (1)Use the hole at R = aa (2)Stopper bolt set position 'H'
----------
aa=79mm
----------
a=12deg+-5deg b=28deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Rack position = approximately aa. (2)Set the stopper screw. (After setting, apply red paint.) (3)Speed = bb, rack position = cc (4)Set the stopper screw. (After setting, apply red paint.) (5)Use the hole above R = dd
----------
aa=18mm bb=0r/min cc=1.5+-0.3mm dd=35mm
----------
a=35deg+-5deg b=15deg+-5deg
