ABSTRACT:
A pneumatically powered or combustion-powered fastener-driving tool for driving a fastener having a head into a gap between two brick faces affixed to a backing board in a siding panel. A workpiece-contacting element is adapted to contact the raised surfaces and is biased toward an extended position. A probe extending into the gap when the workpiece-contacting element contacts the brick faces and is moved into a retracted position is joined to such element so as to be conjointly movable therewith. A nosepiece, which guides the fastener as it is driven, is configured to extend into the gap, beyond the workpiece-contacting element when such element is moved into the retracted position.
