1. Variable lever adjustment
(1)Fix lever B in the idle position using the bolts C and D.
(2)Temporarily fix lever A in center of long hole.
(3)Set the dead point position temporarily and measure the lever angle.
(4)After idle adjustment, loosen the full side stopper bolt D.
(5)Move lever A in full speed direction.
(6)Fix the bolt D at the full speed position.
(7)Fix lever A using bolt E.
