Abstract: A controller for a flywheel driven fastening tool that keeps the flywheel active at or near a ready-to-fire state, for a defined period of time without the continuous user input into the trigger switch or contact trip. The controller controls two (2) or more different timeout periods and flywheel speeds that occur due to different scenarios, such as variations in the user input at the trigger and contact trip. As a result, the controller reduces the wait time for the flywheel to return to a target speed. Thus, user time for performing a nailer application with a flywheel nailer is decreased.

Abstract: A power driver may include a housing, a tool chuck and a power take off mechanism. The tool chuck may have an input shaft mounted for rotation on the housing. The input shaft may support chuck jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft. The transmission shaft may be a gear shaft axially aligned with the input shaft, or a tertiary shaft axially offset from the input shaft.
