Do not check for leaks with your hands. Pin hole (very small) leaks can result in a high velocity oil stream that will be invisible close to the hose. This oil can penetrate the skin and cause personal injury. Use cardboard or paper to locate pin hole leaks. |

Personal injury or death can result from sudden machine movement. Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine. To help prevent possible injury before testing and adjusting any hydraulic system, perform the procedure that follows: |
|
- 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.
- Permit only one operator on the machine. Keep all other personnel away from the machine. Also, all personnel should be visible to the operator.
- Engage the parking brake.
- Stop the engine.
- Place chocks in front of the wheels and behind the wheels.
- 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.
- Loosen any fitting, any hose, or any component.

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. |
|
- Do not remove any load control valve without first blocking or supporting the affected cylinder. To relieve any pressure, loosen the mounting hardware very slowly.
