Abstract
A hand-held electric working machine for cutting a work object is provided. The electric working machine comprises a working portion, a motor, a control unit, and a guide portion. The working portion is configured to cut the work object. The motor is configured to allow rotary power to be generated for allowing the working portion to drive. The control unit is configured to electrically control rotation of the motor. The guide portion is provided on the control unit, thereby forming a first air flow path surrounded by the guide portion and the control unit. The first air flow path is configured to allow air to circulate therein by rotation of the motor, thereby cooling the control unit.
