Abstract
A power tool having an integrated control system includes a workpiece supporting surface, a cutting instrument extendable above the workpiece supporting surface, a guard assembly securable above the workpiece supporting surface for covering at least a portion of the cutting instrument, a motor coupled with the cutting instrument, and a power switch operable for starting the motor for driving the cutting instrument. The power tool includes a control system in communication with the guard assembly for determining if the guard assembly is installed. Before the motor is started, the control system automatically disables the motor if it determines that the guard assembly is not installed. The control system includes a bypass switch for enabling starting of the motor when the guard assembly is not installed.
