16. While the loader arms are fully lowered, visually inspect the quick coupler in order to ensure that the coupler pins (4) are fully extended through the corresponding holes (4A) of the frame mounting bracket. Verify that the coupler pins (4) are engaged before you operate the host machine with the work tool.

17. Use the following procedure to verify engagement of the coupler pins.

    1. Enter the machine.

    2. Close the cab door.

    3. Fasten the seat belt.

    4. Lower the armrest, if equipped.

    5. Start the engine.

    6. Disengage the parking brake.

Removing the Work Tool

Show/hide table

Disengaging the coupler pins will release the work tool from control of the operator. Serious injury or death may result from disengaging the work tool when the work tool is in an unstable position or carrying a load. Place the work tool in a stable position before disengaging the coupler pins.

1. Enter the host machine.

2. Fasten the seat belt.

3. Lower the armrest, if equipped.

4. Start the engine.

5. Disengage the parking brake.

6. Raise the work tool in the transport position. Move the host machine to the desired location for disconnecting the work tool. Refer to Operation and Maintenance Manual, "Transportation" for additional information on transporting the work tool.

7. Position the host machine on a level surface.

8. Rack back the cold planer until the cold planer is slightly off the ground.

9. Place the direction control in NEUTRAL. Engage the parking brake.

10. Turn the engine start switch key to the OFF position in order to stop the engine.

11. Follow the procedure in the Operation and Maintenance Manual of the host machine to relieve any pressure within the auxiliary hydraulic lines. For Caterpillar Skid Steer Loaders and Compact Wheel Loaders, use the following procedure.

    1. Turn the engine start switch to the ON position. Do not start the engine.

    2. Disengage the parking brake.

    3. Operate the auxiliary hydraulic control back and forth and press the control buttons for several times in order to relieve hydraulic pressure within the auxiliary hydraulic lines.
