PROBLEM TO BE SOLVED: To apply the brakes when a stretchable pipe has shrunken during working, in an electric working machine having a stretchable rod capable of being brought to be compact in conveyance and housing.SOLUTION: An electric working machine includes a control unit for controlling the rotation of a motor, a fixing unit 3 to which a handle 41 is installed, and a movable unit 4 sliding against the fixing unit 3 and held to be stretchable, and the movable unit 4 has a cutting blade 155 driven by a motor on the tip of a movable pipe 80 connected to the fixing unit 3, wherein a detection means for detecting if the movable unit 4 is positioned at a predetermined extended position against the fixing unit 3 is installed, and a breaking force is applied to the motor, when the change of a position from a non-extended position to an extended position is detected during rotation of the motor. The control unit continues breaking of the motor when a trigger switch 44 is in a state of being pulled, and the motor is not brought to restart until the stretched state is released and the trigger switch 44 is pulled again after it is once released. |
