Abstract: A rotary hammer operable in a first mode in which only a hammering operation to reciprocate a tool bit along a drive axis is performed and a second mode in which the tool bit is rotationally driven about the drive axis. The rotary hammer includes a motor, a controller to control operation of the motor, a trigger moveable between an off position and an on position, a mode selection dial operable to select the first or second mode, a lock mechanism moveable between a first position and a second position, a linkage moveable between a third position and a fourth position, and a switch in communication with the controller. The switch communicates with the controller to operate the motor at full power or communicates with the controller to operate the motor at a variable speed based on the position of the trigger between the on position and the off position.

Abstract: A rotary hammer includes a housing and a mode selection dial supported in the housing. The mode selection dial includes a cam. The housing supports a motor providing a rotational output. The housing supports a linkage moveable between a first position and a second position in response to engagement by the cam. A loss-of-control detection system measures acceleration of the housing and disables the motor upon the acceleration exceeding an acceleration threshold. The housing supports an operating mode detection system including a magnet and a Hall-effect sensor. The magnet is coupled to the linkage and moveable therewith between a third position corresponding to the first position of the linkage and a fourth position corresponding to the second position of the linkage. The Hall-effect sensor provides an output signal indictive of the position of the magnet. The loss-of-control detection system is selectively disabled based upon the output signal.
