Abstract (en)
[origin: WO2017108745A1] The invention relates to a combustion-powered placing tool (1) for driving fastening elements into a subsurface, comprising at least one main combustion chamber (6) for a compressible fuel, a driving piston (10), which in a starting position is completely retracted, and which can be driven from the main combustion chamber (6) in the placing direction (15) via expandable gases, a prechamber (25), to which an ignition device (26) is assigned, and in which a pressure acting upon the main combustion chamber (6) can be build up prior to the ignition of a fuel-air mixture in the main combustion chamber (6), wherein an additional ignition device (76) is assigned to the main combustion chamber (6). In order to improve the effectiveness and/or the functionality during the driving-in of fastening means, the placing tool (1) comprises a selector device (81), by way of which a selection between a reduced energy operation having an ignition in the main combustion chamber (6) and a high-energy operation having an ignition in the prechamber (25) can be made.
