Continuous Flow (Auxiliary Hydraulics)
Illustration 9 g01010707
(12) Continuous flow switch (13) Lock for quick coupler switch (14) Quick coupler switchSwitch (12) for the continuous flow (auxiliary hydraulics) is located on the right side of the dash panel.The continuous flow function operates with the auxiliary controls. The function allows the operator to select a constant flow rate and flow direction. The flow rate and flow direction is also maintained without continued use of the switches on the joystick controls.When the rate of flow and the direction of flow have been selected using buttons (1), (2) and (3), pressing and releasing switch (12) will maintain the rate of flow and the direction of flow. Refer to Illustration 5 for the location of switches (1), (2) and (3). This maintained operation will continue until any of the following devices are actuated:
Continuous flow switch (12) .
Switches (2) and (3) for auxiliary circuit.
Switch (1) for auxiliary circuit 1 and 2.
Quick coupler switch (14) .
Lock for quick coupler switch (13) .Quick Coupler
The hydraulic quick coupler function allows the operator to operate the pins of the coupler in order to change the work tools that are attached to the coupler. This operation is performed remotely by the operator without the need to exit the machine.Note: The quick coupler function cannot be activated if an auxiliary function is already selected. The controls must be returned to the neutral state before a different function can be requested.Operation of the pins is controlled by three-position switch (14). The switch is located on the left side of the instrument cluster. The switch includes locking device (13) in order to prevent accidental disengagement of the quick coupler pins. The switch is spring centered to the OFF position. To engage the pins, press and hold the bottom of the switch. Release the switch when the quick coupler pins are fully engaged into the work tool. In order to disengage the quick coupler pins, move sliding red locking device (13) downward and press the top of the switch. Hold the switch until the coupler pins are fully disengaged. Refer to Illustration 9 for the location of switches.Note: When quick coupler switch (14) is selected, the solenoid on diverter valve (9) is de-energized.Quick Coupler Circuit DISENGAGED

Refer to Illustration 9 for the location of switches. The ECM of the proportional pilot reducing valves sends a signal to the solenoid of diverter valve for auxiliary circuit 1 (9) which causes the valve to shift to the right. Oil flow is now diverted from the auxiliary circuit to the circuit for
