Abstract

[Problem] To provide a method for controlling a working machine and a working machine that can be easily made multifunctional.[Solution] The method for controlling a working machine 3 controls the supply of a working fluid to an actuator that drives a driven object by a pilot signal Si0 of an operation system generated according to the operation of an operation device 2, thereby moving the driven object bidirectionally between a first position and a second position. The method for controlling the working machine 3 includes preventing a flow of the working fluid in the direction to move the driven object from the second position to the first position by a backflow prevention circuit 7. The method for controlling the working machine 3 is characterized by further including disabling the backflow prevention circuit 7 by the pilot signal Si0 generated during a specific operation, thereby allowing the flow of the working fluid in the direction to move the driven object from the second position to the first position.
