(F) P/N: Part number of the shim L1:Thickness (mm) 1. Adjustment of the control lever (1)Perform idling with the control lever (A) contacting the pushrod (B). At this time, confirm that the spring (C) is not compressed by control lever (A)'s operating torque. (2)To set the stop position, compress spring (C) using the control lever (A) and adjust the rack so that it contacts the guide screw (D) at position L2. Then, set and fix using the lock nut (E). Adjust the rack position L2 at this time using the shim (F). (3)Confirm that the control lever (A) returns to the idling position when pulled in the stop direction and then released.
