Machine Preparation

------ WARNING! ------

Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine. To prevent possible injury, perform the procedure that follows before testing and adjusting the all wheel drive system:

----------------------

  1. Move the machine to a smooth horizontal location. Move away from operating machines and move away from all personnel. Lower all implements to the ground. If equipped, place the control lever for the blade lift control valve in the FLOAT position.

  1. Install the wheel lean locking bolt in the front axle. Install the frame lock pin. Engage the parking brake and stop the engine.

  1. Permit only one operator on the machine. Keep all other personnel away from the machine. Also, all personnel should be visible to the operator.

  1. Put chocks in front of the wheels and behind the wheels.

    ------ WARNING! ------

    Check valves in the hydraulic system may allow pressure to exist in the hydraulic lines after the engine has been stopped. Pressure must be relieved prior to servicing the components of the hydraulic system. Failure to relieve pressure prior to servicing may result in personal injury.

    ----------------------

  1. Carefully loosen the filler cap on the hydraulic oil tank in order to release the pressure in the tank.

  1. Make sure that all hydraulic pressure is released before you perform any of the following procedures:

    • Loosen any fitting, any hose, or any component.

    • Tighten any fitting, any hose, or any component.

    • Remove any fitting, any hose, or any component.

    • Adjust any fitting, any hose, or any component.

  1. Tighten the filler cap on the hydraulic oil tank.

  1. After the pressure in the system has been released, carefully loosen fittings and remove lines or components.
