At operating temperature the implement hydraulic oil tank is hot and under pressure. Hot oil can cause burns.

To prevent possible injury, release the pressure in the implement hydraulic system before hydraulic lines or components are disconnected or removed.

Release the pressure in the implement hydraulic circuits (the boom, the stick and the bucket) before any of the hydraulic lines or any of the components are disconnected or removed. Release the pressure as follows:
1. Shut off the engine and place key in the ON position. Put the hydraulic activation control lever in the UNLOCK position.
1. Move the control levers for the boom, the stick and the swing to all full stroke positions. This will release any pressure that might be present in the pilot system.
1. Return the key to OFF position.
1. Slowly loosen the fill plug on the hydraulic tank, and release the pressure.
1. Tighten the fill plug on the hydraulic tank.
1. The pressure in the hydraulic system has been released, the lines and the components can be removed.
