The kickout system allows the operator to move either the tilt control lever or the lift control lever to a DETENT position.
The lift control lever has detents in two positions: RAISE position and FLOAT position. The lift kickout will cause the lift control lever to return to the HOLD position when the bucket reaches the preset height.
The tilt control lever has a detent in the TILT BACK position. The tilt kickout will cause the tilt control lever to return to the HOLD position when the bucket reaches a preset bucket angle.
Lift Kickout

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 RAISE position. (5) Electromagnet for the LOWER position. (6) Plate. (7) Plate. |
When the operator fully moves the lift control lever to the RAISE position, plate (6) contacts electromagnet (4). 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 (4). 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 (7) contacts energized electromagnet (5). Electromagnet (5) 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 Positioner

Components of the Bucket Positioner (8) Magnet assembly. (9) Bucket positioner switch. (10) Tube. |
Magnet assembly (8) is mounted on the lever assembly. Bucket positioner switch (9) is mounted on tube (10) .
Bucket positioner switch (9) is normally closed. Switch (9) only opens when magnet assembly (8) nears the switch.
Illustration 4 | g00300660 |
Typical Tilt Valve (11) Electromagnet for the TILT BACK position. (12) Plate. |
When the operator fully moves the tilt control lever to the TILT BACK position, plate (12) contacts electromagnet (11). Electromagnet (11) holds the tilt control lever in the TILT BACK position.
As the bucket tilts, magnet assembly (8) moves in the direction of bucket positioner switch (9). When the magnet assembly nears the switch, the switch opens. This stops the flow of current to electromagnet (11). The tilt control lever returns to the HOLD position.
The bucket stops at the correct angle for operation. The bucket stays in this location until the operator places the tilt control lever in the DUMP position.
