Abstract:
1. A method for operating a power tool having a housing and an output member coupled to the housing, the method comprising: initiating a timer; monitoring rotational motion of the housing about a housing axis using a rotational motion sensor disposed in the housing; determining a direction of the rotational motion of the housing about the housing axis, using a control circuit; determining whether the direction of the rotational motion is different from a previous direction of rotational motion of the housing about the housing axis; determining whether a value for the timer exceeds a predetermined threshold; if the direction is different from the previous direction and the timer value is less than the predetermined threshold, initiating a protective action for the power tool; and using the control circuit, driving a motor disposed in the housing to cause the output member to rotate in a direction that corresponds to the detected rotational motion of the housing.
