The hydraulics on the machine can be disabled by the operator with two methods: raising the armrest and pressing the implement lockout switch on the joystick. Then, the relay for the implement lockout is de-energized. Power for the coil of the relay comes from contact J2-1 (wire 116-BR). The machine ECM provides a ground for the relay at J2-33 (wire M927-GN). The ECM de-energizes the relay by removing the ground. The relay provides power to functions that are controlled by the joysticks. Therefore, the following functions are deactivated: rotate clockwise, rotate counterclockwise, cab up and cab down. The main power wire to the relay (wire 140-BU) is connected to the fuse panel. The wire from the relay to the joysticks is L980-GN.

The refueling function allows the machine to be refueled while the machine is in the field. The machine ECM energizes the coil of the relay for the fuel pump through contact J2-17 (wire T776-GY). Ground for the relay is J2-12 (wire H805-BR). The main power wire for the relay is connected to the fuse panel (wire 139-OR). The power is sent from the relay to the fuel pump on wire A893-OR.
