0000001801 STOP LEVER ADJUSTMENT
Adjusting the stop lever's starting injection quantity
(A) Adjusting bolt
(B) Locknut
(C) Stop lever
At injection quantity adjustment, adjust adjusting bolt (A) so that the start injection quantity is as specified. Fix using the nut (B). (Tightening torque T)
Adjust with the lever pushed in direction D. The protrusion of the adjusting bolt A must be L.
----------
L=6.3~10.7mm T=6~9N-m(0.6~0.9kgf-m)
----------
L=6.3~10.7mm
