Drive-in device

Abstract The invention relates to a drive-in device, comprising a hand-held housing (1) having a piston element (2) received therein for transmitting energy onto a fastening element to be driven in, an exchangeable propellant charge, a combustion chamber (3), arranged between the propellant charge and the piston element (2) and extending about a center axis (A), and a control element (8, 9, 10, 11, 12) by means of which a starting position of the piston element (2) can be set to be modified in order to modify the energy transmitted by the propellant charge onto the piston element (2), the control element (8, 9, 10, 11, 12) having an operating element (10) that can be pivoted about the center axis (A).
