Abstract
An electric working machine includes an attachment portion, a motor, and a controller. Multiple types of tip tools are alternatively attached to the attachment portion. The motor drives the tip tool attached to the attachment portion. The controller has first start control and second start control. The controller is configured to execute the first start control so as to determine the type of the tip tool when not having tool type information, and configured to execute the second start control when having the tool type information.

An electric working machine comprising:
- an attachment portion to which multiple types of tip tools are alternatively attached;
- a motor that drives the tip tool attached to the attachment portion;
- and
- a controller that has first start control in which the motor is started and controlled with a first parameter, and second start control in which the motor is started and controlled with a second parameter, the second parameter being different from the first parameter, the controller being configured to execute the first start control so as to determine the type of the tip tool in response to not having tool type information on the tip tool, and the controller being configured to execute the second start control in response to having the tool type information.
