Abstract
A power tool is provided including a housing, an electric motor, a main trigger switch, a side handle having an auxiliary trigger, and a controller operable to control a flow of electric current from a power source to the electric motor. In an embodiment, the controller the motor at start-up only if the main trigger is actuated within a time threshold after the auxiliary trigger is actuated, and otherwise prevent motor operation until both the main trigger and the auxiliary triggers are released and reengaged. In an embodiment, the controller applies a regenerative brake to stop an operation of the electric motor if one of the main trigger or the auxiliary trigger is released while the electric motor is in operation.
