Abstract
A chainsaw having improved cutting workability is provided. A chainsaw is used to cut an object to be worked by a saw chain. A chainsaw main body is provided with an electric motor and a sprocket, and a guide bar around which the saw chain is wound is provided on the chainsaw main body. The guide bar is attached to the chainsaw main body by a screw member serving as an attaching member. A load sensor detects whether or not the guide bar is attached to the chainsaw main body. Rotation of the saw chain is prohibited based upon a signal from the load sensor when the guide bar is not attached to the chainsaw main body.
