Use any pre-existinghardware to secure the switch in the tractor cab.

12 Seven-Way Round Pin ConnectorThis hydraulic system uses auxiliary power from thethe tractor’s 7-way round pin connector. If you tractordoes not have power to the auxiliary circuit, contactyour tractor dealer.

Replace the pre-existing 7-pin connector harnesswith the one provided in this kit.

13 Operator ManualLocate the manual pack on the frame of themachine. Replace the old operator manual with anupdated version of the operator manual. Discard theprevious manual.

14 Sensor Adjustment

The proximity sensor on the left-hand side of thefront of the machine is for starting the gull wingingprocess. This sensor should be set to activate by theupper lift arm. Once the arm passes the sensor, thegull winging process will begin. The rear proximitysensors are located near the wing hinges. Theycontrol the height or angle of the gull wingingprocess.

All three sensors should be given between 1/8-1/4”clearance.

To adjust, loosen the hardware securing the sensor,then slide the sensor up or down in the bracket. Thefurther the sensor is raised in the bracket the moredelayed the gull winging process will be. Once thesensor is set to the desired position, secure thesensor with hardware. Test this configuration bylifting and gull winging the wings of the machine. Ifyou want gull winging to delay or hasten the processmore, make further adjustments until satisfied.

System requires 12VDC+ on light circuit and switch boxto operate correctly.
