Abstract

A fastener detection system is provided for both internal combustion and powder actuated fastener driving tools, and similar powered fastener driving tools. A sensor disposed at a portion of a fastener supply path detects the presence or absence of a fastener.
In the combustion tool, either or both of fuel delivery and combustion ignition are disabled when no fastener is detected. In the powder actuated tool an indicator notifies an operator when the sensor detects the absence of a fastener. The indicator may also be incorporated into the combustion tool.
