0000001501 LEVER
1. Variable lever adjustment
(1)Fix lever (B) in the idle position using bolts (C) and (D).
(2)Temporarily fix the lever (A) in the center of the elongated hole.
(3)Set the dead point position temporarily and measure the lever angle.
(4)Fix the lever (A) at the idle lever angle position using the bolt (E).
(5)Lock using bolt (G).
(6)After completing idle adjustment, loosen the full side stopper bolt (D).
(7)Move the lever (A) in the full speed direction.
(8)Fix bolt (D) at full speed position.
(9)Finally, measure the lever angle and set the idle stopper bolt (C) stop position.
