Abstract

A fastener driving tool arranged to drive fasteners into a workpiece includes a support, at least one wheel movably mounted on the support, a driver arranged to contact and he guided by the wheel when the wheel is in an operative position in use, a nose part retractable relative to the support, and a connection mechanism to operatively interconnect the nose part with the wheel. The tool is arranged such that, in use, the retraction of the nose part causes the connection mechanism to move the wheel from an inoperative position to the operative position. Subsequent forward movement of the driver guided by the wheel toward the nose part causes the operative interconnection between the nose part and the wheel to be broken. Forward movement of the nose part relative to the support, subsequent to the operative interconnection between the nose part and the wheel being broken, causes the operative interconnection between the nose part and the wheel to be re-formed.
