The tool includes a cylinder inside of which is slidably mounted a piston for driving a fastening element, as a result of the explosion inside of a combustion chamber of a mixture of gas and air that has been injected therein from a gas cartridge, after which the tool has come to bear weight against a support, the head switch has retracted and the combustion chamber has closed, followed by actuation of the trigger switch for controlling the spark plug. The tool also includes an element for determining the rate of fire which includes a real-time clock designed to cooperate with a microcontroller of an operating and control module. The arrangement applies well to fastening tools.
