METHOD AND DEVICE FOR OPERATING A HAND-HELD MACHINE TOOL WITH A TANGENTIAL IMPACT MECHANISM
First Claim
1. A method for operating a hand-held machine tool with a tangential impact mechanism driven by a drive shaft and an electric motor, the method comprising adjusting an actual torque provided by the drive shaft to a required torque, wherein the required torque is determined by measuring current of the electric motor, and the required torque is less than a triggering torque of the tangential impact mechanism.
