A combustion-operated setting tool for driving fastening elements in a constructional component includes a device ( 30 ) for adjusting setting energy applied to a setting piston ( 15 ) axially displaceable in a guide space ( 4 ) of a piston guide ( 13 ). The adjusting device ( 30 ) has a separation member ( 31 ) adjustably arranged between the receptacle ( 18 ) and the guide space ( 14 ) of the piston guide ( 13 ) and dividing the combustion chamber ( 20 ) in a first sub-chamber ( 21 ) arranged between the receptacle ( 18 ) and the separation member ( 31 ) and a second sub-chamber ( 22 ) arranged between the separation member ( 31 ) and the guide space ( 14 ) of the piston guide ( 13 ), the separation member ( 31 ) having a plurality of through-openings ( 34, 35 ) for controlling flow of the combustion gases into the guide space ( 14 ) of the piston guide ( 13 ), with an active opening cross-section of at least a portion of the through-openings ( 34, 35 ) changing dependent on an adjustable position of the separation member ( 31 ).
