Personal injury can result from hot oil spray. Make sure all attachments have been lowered, oil is cool and the pressure has been released from the hydraulic system before removing any components or lines. Be sure there is no pressure in the tubing before it is disconnected from the fitting. Do not allow hot oil or components to contact skin. |

Note: Put identification on all lines, hoses, wires, and tubes for installation purposes. Install a cap or a plug in all lines, hoses, or tubes that are disconnected in order to prevent fluid loss. The caps or the plugs will also prevent foreign material from entering the system.
