Abstract
The invention describes a combustion—operated working tool, in particular a setting tool for fastening elements, having a guide cylinder () axially displaceable relative to the device housing (); a piston () displaceably mounted in the guide cylinder (); a housing—integral stop (), which projects into the guide cylinder () to delimit an engagement part of the piston () in the direction of advance of the piston (), when the guide cylinder () is shifted in the direction of advance of the piston (); and an elastic adjusting element (), which is tensioned upon moving the guide cylinder () into the device housing () and by virtue of which an engagement part () can be driven for carrying the piston () opposite to the direction of advance of the piston (), after extension of the guide cylinder () out of the device housing ().
