description	In a portable drilling and percussion-drilling machine with a two-speed gear transmission, with the least amount of outlay the operator is to be protected in the event of an overload occurring in the machine during operation in the first gear transmission stage and the drive motor is to be protected against the occurrence of extreme peak torque values during the operation of the machine in the second gear transmission stage. For this purpose, it is proposed that the mechanical overload clutch be effective solely when the first gear transmission stage is engaged, and that it be bridged when the second gear transmission stage is engaged, and that the limiting of the torque in this stage be performed by an electronic limit-load control system.
