Abstract
A fastener driving tool is provided with replaceable wear guards which provide for three point support of the tool on its side. The three point support system prevents wear on the handle casting and the magazine housing when the tool is dragged across abrasive surfaces, such as roofing surfaces. The fastener driving tool is also provided with a muffler incorporated into a low profile top cap which reduces the overall profile of the tool. A diverter plate is also provided to discharge the exhaust downwardly in front of the tool in a direction more ergonomically pleasing to end users. The fastener driving tool also includes an improved fastener feed system which minimizes nail jams and allows for axial alignment of the driver blade with respect to the fasteners for collated fastener systems wherein the fastener heads are relatively large.
