Abstract

A power tool includes a motor, a drive unit driven by the motor, and a trigger switch and a forward-reverse switch each operable by a user. The trigger switch is switchable between an activation state and a deactivation state. The forward-reverse switch switches a motor rotation between forward and reverse. The power tool also includes a control unit that drives the motor based on operation of the trigger switch and allows switching of an operation mode of the power tool between first and second modes. In the first mode, the motor rotation is switched to that selected by the forward-reverse switch. In the second mode, when the activation state is switched to the deactivation state, the motor rotation is switched so that the motor is driven in a direction opposite to the present rotation direction when the trigger switch is activated next.
