Abstract
A drive-in tool drives in fastening elements and includes a driving ram and a drive unit. The driving ram is displaceably supported in a guide. The drive unit has a drive flywheel and a return device. The drive flywheel is set in rotation by an electric motor, and the return device displaces the driving ram from an initial position after the completion of the drive-in process. The return device has a return motor separate from the electric motor, and the return motor is connected to the driving ram by a return mechanism.
