    Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before connecting hydraulic or other lines. Protect hands and body from high-pressure fluids. See additional information, Avoid High-Pressure Fluids in Safety section.

    Level bucket and lower flat on the ground.


  11. Relieve hydraulic pressure. (See Relieve Hydraulic Pressure in Controls section.)
