Adjustment of Lift and Tilt Hydraulic Control Levers
Use caution to avoid possible personal injury when adjusting the bucket positioner and lift kickout.Apply the Parking/Secondary brake and block the tires to prevent sudden movement of the machine.Keep personnel off the machine. Clear the area when working under or around the bucket linkage. With the bucket raised, proper support must be provided for the bucket and/or the linkage.
Control Lever Adjustment
1. End (on valve stem of pilot control valve). 2. Locknut. 3. Washer. 4. Rod. 5. Balljoint (on control lever). 6. Control lever (either lift or tilt). 7. Washer. 8. Locknut. 9. Detents. 10. Detent roller. 11. End (on solenoid). 12. Solenoid. (A) Raise and Tilt Back. (B) Float.1. Be sure the lift kickout and bucket positioner are correctly located. See sections, Lift Kickout Adjustment Procedure and Bucket Positioner Adjustment Procedure.2. Adjust the length of each rod (4) in end (1) and balljoint (5) on each control lever (6) as follows: Make the adjustment so detent roller (10) will keep the lift control lever (6) and the control valve stem in the RAISE and in the FLOAT positions with full travel of the valve spool in either direction. The detent roller for the tilt control lever must hold the lever and the control valve stem in only the TILT BACK position, with full travel of the valve spool in either direction.a. Move lift control lever (6) to let detent roller (10) keep it in the RAISE position. The detent roller must keep the tilt control lever in the TILT BACK position.b. Turn locknut (2) on rod (4) for the lift control until the nut is just against washer (3), then turn the locknut three more turns against the washer. Do the same for locknut (2) for the tilt control.c. Move lift control lever (6) so detent roller (10) keeps the lever in the FLOAT position. Turn locknut (8) on rod (4) until the nut is just against washer (7), then turn the locknut three more turns against the washer.3. Raise the bucket as high as it will go and tilt it back to the limit of its travel. This is to make sure that kickout solenoids (12) will be energized (have electrical power to pull the solenoid plunger in) when the key switch is on. Use blocks or jack stands to support the lift arms and bucket in this position.4. Be sure the key switch is ON to engage the kickout solenoids. Each solenoid plunger should be pulled into its solenoid body. Measure the distance between the top of the solenoid plunger and the solenoid mounting surface, distance X.5. Turn the key switch off to remove the electrical power from the solenoids.6. Move the lift control lever to the RAISE detent position. Move the tilt control lever (6) to TILT BACK detent position. The roller should be in the detent.7. Distance Y is the distance from the top of the extended solenoid plunger to the solenoid mounting surface. Measure distance with
