Excessive weight and length may damage external rotating components. • Speed of operation is a major consideration. All swing cylinders MUST BE USED WITH FLOW LIMIT VALVES to show the rotation action. • Full second rotation time is recommended. • Care should be used when select hydraulic power sources - be aware of maximum operating pressures.
