Abstract
An object of the present invention is to operate the working machine etc. with satisfactory responsiveness as intended by the operator while enhancing engine efficiency, pump efficiency, and the like, where a first engine target revolution ncomadapted to a current pump target discharge flow rate Qsum is set, and when determined that the current pump target discharge flow rate Qsum is greater than a predetermined flow rate (10 (L/min)), a revolution nM (e.g., 1400 rpm) greater than an engine low idle revolution nL is set as a second engine target revolution ncomdetermining that operation leverstoswitched from a non-operation state to an operation state. The engine revolution is controlled so that the second engine target revolution ncomis obtained if the second engine target revolution ncomis equal to or greater than the first engine target revolution ncom
