Abstract
An electric tool adapted to perform tightening operations where torque is delivered in pulses to tighten a screw joint. The electric tool including an electric motor drivingly connected to an output shaft. A processor and a memory storing software instructions that, when executed by the processor cause the electrical tool, retrieve a first power level parameter pindicating a first power level to be used for torque pulses up to a torque threshold. And retrieve a second power level parameter pindicating a second power level to be used for torque pulses above the torque threshold. Then control the speed of the electric motor, so that the electric tool provide torque pulses on the output shaft with the first power level puntil the torque threshold is reached. And control the speed of the electric motor, so that the electric tool provide torque pulses on the output shaft with the second power level p
