Abstract
Official abstract text for this publication.
A combustion-powered fastener-driving tool includes a combustion-powered power source including a cylinder head and a combustion chamber defined by the cylinder head, a valve sleeve and an upper surface of a reciprocating piston, the valve sleeve reciprocable relative to the cylinder head between a rest position and a pre-firing position. A lockout device is associated with the trigger and has an actuated position configured for preventing the reciprocation of the valve sleeve away from the pre-firing position until the trigger is released.
