Adjust magnet assembly (1) on lift arm (3) so that the lower edge of the magnet is even with the lower edge of switch assembly (2). Adjust switch assembly (2) to get a clearance between the switch and magnet assembly (1) of 6 to 10 mm (.24 to .39 in.). Tighten the bolts that hold the magnet assembly in place. Start and run the engine. The lift kickout switch action must move the lift control lever from RAISE to HOLD position before the lift arm assembly gets to the top of its travel. If the kickout was too soon, move magnet assem- bly (1) away from switch assembly (2). If the kickout was not soon enough (cylinder rods hit the heads inside the lift cylinders), move magnet assembly (1) toward switch assembly (2). L I F T K I C K O U T 1. Magnet assembly. 2. Switch assembly. 3. Lift arm. BUCKET POSITIONER ADJUSTMENT PROCEDURE 1. 2. With the engine running, move the tilt control lever to put the bucket in the correct angle to dig and then move the tilt control lever to the HOLD position. Lower the bucket to the ground and stop the engine. Make sure that magnet assembly (2) has its longer length perpendicular (in a vertical posi- tion) to tube assembly (1). Tighten the set screws in the magnet assembly. 3. Measure dimension (A) between magnet assem- bly (2) and switch assembly (3). The correct dimension is 6 to 10 mm (.24 to .39 in.). 4. To change dimension (A), loosen bolts (5) then tighten screw (4) just enough and move tube assembly (1) and the switch away from magnet assembly (2). Switch assembly (3) must be verti- cally centered with magnet assembly (2). T Y P I C A L B U C K E T P O S I T I O N E R 1. Tube assembly. 2. Magnet assembly. 3. Switch assem- bly (under cover). 4. Screw. 5. Bolt (two). A. Dimension 6 to 10 mm (.24 to .39 in.). 5. Move tube assembly (1) until the front edge of switch assembly (3) is even (flush) with the front edge of magnet assembly (2). 6. Loosen screw (5) and tighten two bolts (6) to a torque of 15 ± 4 N.m (11 ± 3 lb. ft.). 7. Start and run the engine. Put the lift arm assem- bly parallel to the ground with the bucket in a full dump position. Put the tilt control lever in the TILT BACK (detent position). The action of the bucket positioner moves the control lever from TILT BACK to HOLD position when the bucket is at the correct angle to dig. 8. If the bucket angle to dig was too flat, move tube assembly (1) and the switch toward the bucket. If the angle to dig was too much, move tube assembly (1) and switch toward the tilt cylinder.
