2. When fitting hydraulic motors or cylinders, ensure that connections have been made correctly, as per
manufacturer’sinstructions.
3. Before connecting hoses to the tractor hydraulics, ensure that tractor and machine circuits are not under
pressure.
4. Itisstronglyrecommendedthattheoperatormarksthehydraulicconnectionsbetweentractorandmachineto
