Abstract

A method for controlling an electrical tool having a motor, a transmission mechanism, a control device, and a function member. The motor drives the function member to move in a reciprocating manner via the transmission mechanism. The function member has a standard position and the control device controls the motor. The control device at least has an associated position sensor capable of detecting a position of the function member. The method for controlling the electrical tool includes at least a reset movement process that is used to reset the function member to the standard position after the function member completes more than one cycle of reciprocating movement.
