摘要： A control system for extending and retracting a ram of a hydraulic coupler for coupling an attachment to an arm of an excavator or back hoe, said control system being adapted to provide an audible and/or visual alert to an operator to indicate a leak of fluid or loss of fluid pressure from said ram and/or from a hydraulic circuit supplying said fluid to the ram. Preferably the control system further comprises a flow sensor for sensing the flow of fluid in a feed line for supplying pressurised fluid to the ram and/or a pressure sensor for sensing the pressure of fluid in said feed line, said control system including at least one indication device for providing said audible and/or visual alert to an operator to indicate a leak of fluid or loss of fluid pressure in response to, or as a function of, the output of the flow sensor and/or the pressure sensor.
