Abstract

A combustion-powered fastener-driving tool includes a combustion-powered power source, a valve sleeve reciprocable relative to the power source between a rest position and a firing position, and a lockout device in operational proximity to the valve sleeve and configured for automatically preventing the reciprocation of the valve sleeve from the firing position until a piston in the power source returns to a pre-firing position.
