Abstract
An electric power tool includes: a motor; an output shaft; and a power transmission mechanism that transmits a rotational output of the motor to the output shaft. A motor control unit controls rotation of the motor in accordance with an on operation of the user operation switch performed by a user. A detector detects physical quantity data while the motor is being rotated. A status determination unit determines whether the electric power tool is in a deteriorated status, by using the physical quantity data. A notification interface communicates that the electric power tool is in a deteriorated status while the motor is not being rotated.
