Components of the Lift Kickout (1) Lift positioner switch. (2) Switch holder. (3) Magnet assembly.Lift positioner switch (1) is located on the left side of the loader frame. Magnet assembly (3) is located on the pivot of the lift arm.Lift positioner switch (1) is normally closed. The switch only opens when magnet assembly (3) nears the switch.

Lift Valve (4) Electromagnet for the LOWER position. (5) Plate. (6) Plate. (7) Electromagnet for the RAISE position.When the operator fully moves the lift control lever to the RAISE position, plate (6) contacts electromagnet (7). The electromagnet will hold the lift control lever in the RAISE position.As the bucket raises, magnet assembly (3) moves. When the magnet assembly nears switch (1), the switch opens. This stops the flow of current to electromagnet (7). The lift control lever returns to the HOLD position.The lift arms stop before the lift cylinder rods are fully extended. The lift arms will stay at this height until the operator places the lift control lever in the LOWER position.When the operator moves the lift control lever to the LOWER position, magnet assembly (3) moves away from switch (1). The switch will return to the CLOSED position.When the bucket is resting on the ground, the operator can move the lift control lever to the FLOAT position. The bucket will move up and down with the contour of the ground. Plate (5) contacts energized electromagnet (4). Electromagnet (4) will hold the lift control lever in the FLOAT position. The lift control lever remains in the FLOAT position until the operator moves the lift control lever.Reference: For more information on adjusting the lift kickout positioner, refer to the Service Manual module for Testing and Adjusting, "Lift Kickout Positioner - Adjust" for the machine that is being serviced.Bucket Or Attachment Positioner
There are two options for the bucket positioner. Both options are controlled by a switch in the operator compartment. The switch is near the ceiling of the compartment to the left of the operator.

Typical Tilt Valve (13) Electromagnet for the TILT BACK position. (14) Plate.The attachment positioner consists of switch holder (10), switches (11) and (12), magnet assembly (9), electromagnet (13), and control switch (8). Switch holder (10) is on the left tilt cylinder. Switches (11) and (12) are located in the switch holder. Magnet assembly (9) is on the rod end of the left tilt cylinder. Electromagnet (13) is part of the tilt pilot control valve. Switch (12) is for operation of the attachment. Switch (11) is for operation of the bucket or of another attachment. Control switch (8) allows the operator to use either the switch for the bucket positioner or the switch for the attachment positioner. This will permit the operator to change attachments without readjusting
