Pressure Switch (Implement)The pressure switch (implement) sends a signal to the Controller at CONN172-17. This signal tells the Controller that the implement is operating.Pressure Switches

Work Tool Pressure SwitchJoystick Pressure SwitchMedium Pressure SwitchThe three pressure switches are identical. The three pressure switches tell the Controller that a specific portion of the hydraulic circuit is operating. The Controller will determine the parameters to use in order to control the hydraulic output.The work tool pressure switch sends a signal to the Controller at CONN172-28. This switch senses an increase in pressure when the foot pedal for the work tool is pressed. The joystick pressure switch sends a signal to the Controller at CONN172-29. This 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 Controller at CONN172-45. This switch senses an increase in pressure in the pilot line. Hydraulic Lock Limit Switch ( Neutral Start)

Cab (bottom view) (6) Box Limit switch (4) and plunger (5) are contained in box (6). The limit switch is activated by hydraulic activation control lever (3) .The engine will not start unless hydraulic activation control lever (3) is in the LOCKED position. If some one tries to operate the machine unexpectedly, the machine will not operate.When hydraulic activation control lever (3) is placed in the UNLOCKED position, pilot oil now flows to the pilot control valves.Joystick Switch (Hammer)
Illustration 10 g00933445
(1) Joystick Switch (Hammer)Switch (1) can be used in order to operate the work tool. When switch (1) is pressed, power is sent directly to the hammer solenoid. The hammer turns ON. When the switch is released, power to the solenoid is discontinued. The hammer turns OFF. This switch is present on all machines except for the machines that are equipped with System G14 .One-Way/Two-Way Flow (Direction Switch)
