Horn
When horn switch (1) is depressed, power is sent to the horn relay. The horn relay sends power to the horn.Joystick Thumb Wheel for Clockwise Rotation
Joystick thumb wheel for clockwise rotation of the work tool (3) is located on the left joystick. When the joystick thumb wheel is pressed FORWARD, a signal is sent to the solenoid for medium pressure (clockwise rotation). The work tool will rotate in a clockwise direction. The joystick thumb wheel is not serviceable. The joystick is serviceable.Joystick Thumb Wheel for Counterclockwise Rotation
Joystick thumb wheel for counterclockwise rotation of the work tool (3) is located on the left joystick. When the joystick thumb wheel is pressed BACKWARD, a signal is sent to the solenoid for medium pressure (clockwise rotation). The work tool will rotate in a clockwise direction. The joystick thumb wheel is not serviceable. The joystick is serviceable.Extension of the Work Tool Joystick Thumb Wheel
Joystick thumb wheel for extension of the attachment control valve (4) is located on the right joystick. When the joystick thumb wheel is pressed FORWARD, a signal is sent to the solenoid for the attachment control valve. Pilot oil will shift the spool in the attachment control valve. The oil from the pump will flow to the work tool. The joystick thumb wheel is not serviceable. The joystick is serviceable.Retraction of the Work Tool Joystick Thumb Wheel
Joystick thumb wheel for retraction of the attachment control valve (4) is located on the right joystick. When the joystick thumb wheel is pressed BACKWARD, a signal is sent to the solenoid for the attachment control valve. Pilot oil will shift the spool in the attachment control valve. The oil from the pump will flow to the work tool. The joystick thumb wheel is not serviceable. The joystick is serviceable.Joystick Switch (ON/OFF)
The work tool operates when the switch is depressed. When the switch is pressed, a signal is sent to the machine ECM. The machine ECM sends a signal to the solenoids to control the attachment control valves for one-way flow to the work tool. When the switch is released, the machine ECM discontinues power to the solenoids. The work tool stops operating.One Touch Low Idle
When one touch low idle (6) is pressed, the engine rpm is dropped. When a function is moved from the neutral position, one touch low idle is turned off and the machine resumes the set throttle setting.Foot Pedal (Electric)
