Abstract

The invention relates to a portable handheld work apparatus such as a motor-driven chain saw having an internal combustion engine, a fuel tank and an apparatus housing. The engine has a crankcase and at least one cylinder. The fuel tank is attached to the crankcase at a distance by means of two flanges whereby a mounting space is provided between the flanges, the crankcase and the fuel tank. This mounting space accommodates necessary components of the work apparatus and is closed by cover plates attached to the crankcase and the fuel tank or on the flanges.
