One aspect of the present disclosure provides an electric power tool including an output shaft, a motor, a manual switch, a memory device, a first circuit, and a second circuit distinct from the first circuit. The memory device stores two or more sets of job information. Each of the two or more sets of job information includes at least one operation setting of the motor for performing an associated tightening operation. The first circuit (i) receives one set of job information and (ii) drives the motor in accordance with the at least one operation setting included in the one set of job information based on the manual switch being or having been manually operated. The second circuit outputs a next set of job information from the memory device to the first circuit based on the first circuit having completed driving the motor.
