(10) Quick coupler indicator panelNote: When using the quick coupler to engage a work tool, always verify that the coupler wedges are engaged in the proper position to lock the work tool. Visually inspect the coupler wedge position or manipulate the tool in a manner that will confirm that the tool is locked in place.The quick coupler gives the machine the ability to change work tools without leaving the cab. Press the bottom of the quick coupler switch (9) to engage the coupler pins. To release the coupler pins, the red tab on the bottom of the switch must be pressed to unlock the switch then press the top of the switch to activate the system.The quick coupler valve is located on the left side of the loader frame underneath the cab. The load sense solenoid (2) and extend/retract solenoid (4) are used to engage or disengage the work tool with the quick coupler pins. Two manual valves (8) allow the oil to flow from the quick coupler valve to the quick coupler cylinders (7). The quick coupler cylinders for the quick coupler locking pins are located in the coupler frame.

(10) Quick coupler indicator panelOil for the quick coupler valve is supplied from the implement valve. In order to extend quick coupler cylinders (7), load sense solenoid (2) is energized by the relay driver module and oil is sent to upstroke the main pump. Extend/retract solenoid (4) is de-energized by quick coupler switch (9). Oil flows through the solenoid valves, the manual valves (8), and to the head end of quick coupler cylinders (7). Oil in the rod end of quick coupler cylinders (7) flows through manual valves (8) and extend/retract solenoid valve (2) to the hydraulic tank.In order to retract quick coupler cylinders (7), load sense solenoid (2) is energized by the relay driver module and oil is sent to upstroke the implement pump. Extend/retract solenoid valve (4) is energized by the quick coupler switch (9). Oil flows through extend/retract solenoid valve (4), the manual valves (8), and to the rod end of quick coupler cylinders (7). The oil also flows to the pilot port of the pilot operated check valves (6) located on the cylinder. The pressure applied to check valves (6) will allow the oil in the head end of quick coupler cylinders (7) to flow back through check valves (6), manual valves (8), extend/retract solenoid valve (4), and to the hydraulic tank.ECM
When the quick coupler system is equipped on the machine, the relay driver module and the implement ECM will
