Abstract
A device for impacting a fastener in one embodiment includes a lever arm pivotable between a first position whereat a flywheel is spaced apart from a drive mechanism and a second position whereat the flywheel can contact the drive mechanism, a lever arm solenoid for pivoting the lever arm between the first position and the second position, a drive mechanism sensor for generating a position signal indicative of the position of the drive mechanism, a timer for generating a timing signal, a memory including program instructions, and a processor operably connected to the memory for executing the program instructions to (i) energize the solenoid to pivot the lever arm to the second position, (ii) de-energize the solenoid based upon the position signal, and (iii) de-energize the solenoid based upon the timing signal.
