Linkage Adjustment Procedure:
DO NOT use control lever (2) to shut OFF the engine.To shut engine OFF, pull up on accelerator treadle (11).1. Tighten nut (A) just enough so position of control lever (2) is not affected by the operation of the accelerator treadle (11) and decelerator treadle (9).2. With the parking brake ON and engine stopped, BE SURE disconnect switch is OFF.3. Remove pin (4).4. Loosen LOW IDLE stop (7) and HIGH IDLE stop (5) so they do not touch lever (12).5. Move control lever (2) to LOW IDLE position.6. Turn LOW IDLE stop (7) until it touches lever (12) and tighten locknut (8).7. Adjust length of rod (13) so distance from top of lever (15) to bottom of floor plate (10) is 1.50 in. (38.1 mm) as shown.8. Loosen locknut (14) and adjust length of rod so top of decelerator treadle (9) is .19 in. (4.8 mm) above floor plate (10) as shown. If machine is equipped with a thick floor insulation pad, (used with enclosed cab), adjust decelerator treadle (9) so top of treadle is .38 in. (9.7 mm) above top of floor plate and tighten locknut (14).9. Move control lever (2) to HIGH IDLE position.10. Turn HIGH IDLE stop (5) until it touches lever (12) and tighten locknut (6).11. Loosen locknut (16) and adjust accelerator treadle (11) so that distance from bottom of plate on treadle to top of floor plate (10) is 2.38 .12 in. (60.5 3.0 mm) as shown.12. Move lever (3) to HIGH IDLE position and adjust length of rod (1) so pin (4) can be installed.13. Install pin (4).For 561D Pipelayer
