  "textContent": "An engine-driven working machine (10) according to the present invention has a controller (14), which varies a control value of a solenoid valve (20) so as to decrease or increase an opening degree of the solenoid valve (20) when a rotating speed of an engine (12) is within a predetermined high rotating speed range (R1) and the rotating speed of the engine (12) is lower or higher than a predetermined rotating speed (R2), respectively. When the control value of the solenoid valve (20) is varied so as to decrease the opening degree of the solenoid valve (20) and corresponds to a predetermined opening degree larger than a fully-closed state, the control value is set to a limitation value (VL).",
