Joystick Control (C) Tilt control. (D) Lift control. (E) Auxiliary control.The machine can be equipped with a joystick control. The joystick control can be equipped with either two-position sensors or three-position sensors. The sensor for the third function is controlled by the thumb wheel that is built into the joystick handle. The position sensors send the position of the joystick handle to the implement (ECM). Also, the joystick control is not equipped with electromagnets for detents. The joystick control is equipped with soft detents. For additional information about the operation of the joystick control and the soft detents, refer to the Systems Operation, "Sensors".The joystick control can be arranged in four different combinations. The joystick control can be either a two-function joystick or a three-function joystick. Also, either joystick function can be equipped with the Autodig System. If the machine is equipped with the Autodig System, refer to the Systems Operation, "Switches" for the location of the Autodig trigger switch on the joystick control.ReferenceFor additional information on the joystick control, refer to Systems Operation, "Electrohydraulic Control" for the machine that is being serviced.ReferenceFor additional information on the operation of the autodig system, refer to Systems Operation, "Aggregate Autodig" for the machine that is being serviced.
