Abstract
The invention relates to a fuel-powered setting device for driving securing elements into a substrate, comprising at least one main combustion chamber for a fuel, a drive piston that can be driven out of the main combustion chamber in a setting direction by expandable gases, and a prechamber with which an ignition device is associated and in which a pressure acting on the main combustion chamber can build up prior to a fuel-air mixture being ignited in said main combustion chamber. To improve efficiency and/or functionality when driving in securing elements, the setting device can be operated in different energy classes by an energy adjustment.
