<p>PROBLEM TO BE SOLVED: To provide a powered working machine capable of preventing the apparatus breakage, energy loss, etc., caused by the maloperation of an output operation member and a braking operation member. SOLUTION: A pair of output operation restriction parts and a pair of braking operation restriction parts are placed between an output operation system 12-13-14 to control the output of a power source 3 to a power working member 2 and a braking operation system 10-15-16 to stop the motion of the power working member 2. The output operation restriction parts are brought into contact with each other to restrict the output operation to the power working member by the output operation member 12 when the power working member 2 is in braked state. The braking operation restriction parts are brought into contact with each other to restrict the breaking operation of the power working member 2 by the braking operation member 10 when power is transmitted from the power source 3 to the power working member 2.</p> |
