Joystick "Retract"
Button (4) for retraction of the attachment control valve is located on the right joystick. When the button is pressed, 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 button is not serviceable. The joystick is serviceable.Foot Switch (Hammer)

Foot Switch (Hammer)
The hammer turns ON when the foot switch is depressed. When the foot switch is pressed, a signal is sent to the machine ECM. The machine ECM sends a signal to the solenoid for the hammer. When the switch is released, the machine ECM discontinues power to the solenoid. The hammer turns OFF.Left Pedal

Pedal (14) for extension of the attachment control valve is located left of the travel pedals. When the pedal 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.Retraction of the Work Tool (Pedal)
Pedal (14) for Retraction of the attachment control valve is located left of the travel pedals. When the pedal 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.Pressure Switch (Implement)

Pressure Switch (Implement)
The pressure switch (implement) sends a signal to the ECM at C27-9. This signal tells the ECM that the implement is operating.Pressure Switches

Joystick Pressure Switch
Medium Pressure Switch
The two pressure switches are identical. Each of the two pressure switches tell the ECM that a specific portion of the hydraulic circuit is operating. The ECM will determine the parameters to use in order to control the hydraulic output.The joystick pressure switch senses an increase in pressure when the joysticks that control the implements are operated.The medium line pressure switch sends a signal to the ECM at C27-42. This switch senses an increase in pressure in the pilot line.Hydraulic Lock Limit Switch (Neutral Start)

(6) Limit switch Limit switch (4) and plunger (5) are contained in box (6). The limit switch is activated by hydraulic activation control lever (3).When hydraulic activation control lever (3) is shifted to the LOCKED position, the hydraulic activation solenoid is de-energized. Pilot oil does not flow to the pilot control valves. Thus, when the joysticks and/or the travel levers/pedals are operated, pilot oil will not flow to the main control valve in order to activate the cylinders or the motors.Note: The engine will not start unless hydraulic activation control lever (3) is in the LOCKED position.When hydraulic activation lever (3) is in the locked position, the neutral start relay will be active. This allows the
