0000001901 STOP LEVER ADJUSTMENT
Adjustment of the stop lever
1. Confirm that the starting injection quantity is within standards at the normal position.
If below the specified lower limit, move the stop lever serrations one tooth and reconfirm.
2. Pull the stop lever (A) to the fuel cut direction at the standard idling speed of N and adjust the screw (B) to the position Q.
Fix nut (C) to the torque T at the position where the clearance between the stop lever and the end of the screw is L mm (the screw is returned 2 turns).
The head of the screw must protrude above the face of the nut. If the head of the screw is below the face of the nut, adjust the clearance between the stop lever A and the end of the screw at Q to L mm or more.
3. If adjustment in item 2 is not possible, move the stop lever installation position 1 tooth.
4. The stop lever's operating force is max. M kg (at R = 35). The stop lever must operate smoothly.
