description A switch (15) is configured so as to be operated with two positions of a locked position when an attachment is held and an unlocked position when an attachment is released. Furthermore, a control device (16) receives an operation signal that is output when the switch (15) is operated to the locked position or the unlocked position and switches and controls an electromagnetic switching valve (13) so that the pressure of a hydraulic pump begins to rise and so that, at a stage when a predetermined time has passed, the pressure raising in the hydraulic pump is stopped.
