Abstract
A setting tool includes a piston guide (13) displaceably arranged in the tool housing (11) and in a hollow chamber (14) of which a piston guide (13) is displaceable under action of a propellant from an initial position thereof to an end position thereof, a device (20) for braking displacement of the setting piston (15) in its end position at an end of a setting process, and a wear recognition device (30) associated with the setting piston braking device (20) for automatically blocking a setting process dependent on a wear condition of the setting piston braking device.

A setting tool, comprising a housing (11);
- a piston guide (13) displaceably arranged in the housing (11);
- a setting piston (15) displaceable in a hollow chamber (14) of the piston guide (13) under action of a propellant from an initial position thereof to an end position thereof;
- a device (20) for braking displacement of the setting piston (15) in the end position thereof at an end of a setting process;
- and a wear recognition device (30) associated with the setting piston braking device (20) for automatically blocking a setting process dependent on a wear condition of the setting piston braking device.
