Abstract

A pneumatic fastener driver is operable in a single sequential mode and a bump-fire mode. The pneumatic fastener driver includes a housing, a nosepiece extending from the housing from which fasteners are ejected, and a trigger moveable between a default position, in which a drive cycle is inhibited from initiating, and a depressed position, in which the drive cycle is permitted to be initiated. The pneumatic fastener driver further includes a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval that begins once the trigger is actuated from the default position to the depressed position.
