0000001501 LEVER

Speed lever adjustment 1. (1) For idling hold the speed lever (a) against the push rod (B). (2)At this time, confirm that the spring (C) is not bent by the operating torque of the speed lever. 2. (1) To stop, bend the spring (C) using the speed lever. (2)Position the rack at L2. (Adjustment is performed using the shim (F).) (3)Set and fix using lock nut (E) so that it contacts the guide screw (D). 3. Confirm that the speed lever returns to the idling position when pulled in the stop direction and then released.
