ABSTRACT:
A portable power tool includes a power module and a tool module, e.g., a chain saw module which is attached to the power module and which can be readily exchanged with another tool module, e.g., a cutter module. The power module includes a power source such as two-stroke gasoline engine with a drive shaft. To facilitate rapid exchange of tool modules, there are two or more torque transmission members such as a pulley and a sprocket wheel on the drive shaft, so that different tool modules can be attached to the power module without removal and replacement of the torque transmission member.
