SLEWING-TYPE WORKING MACHINE
An opening and closing motion control section controls an optional control valve so as to reduce opening degree of the optional control valve in a case where a first opening reduction condition is satisfied that a slewing operation detection section detects an operation amount equal to or more than a reference operation amount set in advance so that the reference operation amount is larger than a minimum operation amount of a slewing operation member for causing slewing motion of an upper slewing body and that an optional operation detection section detects operation received by an optional operation member.
