The kickout system is made up of the following components: lift kickout, work tool positioner, pilot control valve and control panel.
The kickout system allows the operator to move either the tilt control lever or the lift control lever to a DETENT position.

The kickouts are controlled by two switches that are located in the control panel. The kickout switch (on/off) (2) activates the work tool positioner and the lift kickout. The kickout switch (on/off) must be placed in the ON position in order to turn on the electromagnets. When you activate the electromagnets, the operator must cycle the implements at least one time. One cycle of the implements will energize the electromagnets.
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 work tool reaches the preset height.
The tilt pilot control valve 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 work tool reaches the preset angle.
Lift Kickout
For the location of the kickout switch (on/off), refer to Illustration 1.

Lift positioner switch (3) is located on the left side of the loader frame. Magnet assembly (5) is located on the pivot of the lift arm.
Lift positioner switch (4) is normally closed. The switch only opens when magnet assembly (3) nears the switch.

When the operator fully moves the lift control lever to the full RAISE position, plate (8) contacts electromagnet (9). The electromagnet will hold the lift control lever in the RAISE position.
As the bucket raises, magnet assembly (5) moves. When the magnet assembly nears switch (3), the switch opens. This stops the flow of current to electromagnet (9). 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 (5) moves away from switch (3). The switch will return to the CLOSED position.

Work Tool Positioner
For the location of the kickout switch (on/off) and the bucket/forks switch, refer to Illustration 1.

The work tool positioner consists of the following components: pilot control valve, rocker switches (1, 2), Magnet assembly (10), switch holder (11) and positioner switches (12, 13). Switch holder (11) is on the left tilt cylinder. Positioner switch (12) and positioner switch (13) are located in switch holder (11). Magnet assembly (10) is on the rod end that is attached to the rod eye of the left tilt cylinder. Electromagnet (13) is part of the tilt pilot control valve.
Switch (13) is for positioning of the fork assembly. Switch (12) is for positioning of the bucket. Bucket/forks switch (1) allows the operator to use either the positioner switch for the bucket or the positioner switch for the fork assembly. This will permit the operator to change between a bucket and a fork assembly without manually readjusting the position of the positioner switches. The bucket or the forks are usually the two work tools that use the work tool positioner.

When the operator places bucket/forks switch (1) to the TOP position and the operator fully moves the tilt control lever to the full TILT BACK position, plate (15) contacts electromagnet (14). The electromagnet will hold the tilt control lever in the TILT BACK position.
As the bucket tilts back, magnet assembly (10) moves in the direction of switch (12). When the magnet assembly nears the switch, the switch opens. This stops the current flow to the electromagnet and the electric circuit is broken.
When the current flow is interrupted, electromagnet (14) can not hold plate (15). The tilt control lever returns to the HOLD position.
The bucket stops at the correct angle for operation. The bucket will stay in this position until the operator places the tilt control lever in the DUMP position.
When the operator pushes the bottom of bucket/forks switch (1) and the operator moves the tilt control lever to the full TILT BACK position, plate (15) contacts energized electromagnet (14). The electromagnet will hold the tilt control lever in the TILT BACK position.
As the fork assembly tilts back, magnet assembly (10) moves in the direction of switch (13). When the magnet assembly nears the switch, the switch opens. This stops the current flow to the electromagnet and the electric circuit is broken.
When the current flow is interrupted, electromagnet (14) can not hold plate (15). The tilt control lever returns to the HOLD position.
The fork assembly stops at the correct angle for operation. The fork assembly will stay in this position until the operator places the tilt control lever in the DUMP position.
