Minimum-maximum speed specification adjustment (when running) (1)After completing governor adjustment, hold the 2-stage changeover lever (C) so that the speed lever (A) contacts the full speed stopper. (2)In this condition, the load lever is held in the idle position. (3)Adjust bolt (E) so that the clearance between the pin underneath lever (C) and the end of the long groove in link (D) is L. (4)Lock using the nut. 2. Variable speed specification adjustment (at operation) (1)Hold the 2-stage changeover lever (C) so that the load lever (B) contacts the full load stopper. (When the load lever is equipped with a cancel mechanism, move it so that it contacts the stopper without canceling.) (2)In this condition, confirm that the speed lever (A) moves from idle to full speed.
