1. Variable lever adjustment
(1)Set lever (a) in the idle position.
(2)Set lever (c) at the dead point using screw (b) and then fix using bolt (d).
(3)When the dead point position cannot be obtained, set the lever (c) at the position closest to the dead point (at the end of the elongated hole) (in the direction of arrow A).
