ABSTRACT:
An electric hand power tool has a housing, an air-cooled electric motor which is accommodated in the housing, a tool which is driven by the electric motor a protective hood which at least partially covers the tool, the housing having a handle and an auxiliary handle for a two-hand guidance of the hand power tool, the auxiliary handle being positioned in a plane transverse to a plane of the first-mentioned handle and, with reference to a work direction, before the first-mentioned handle, the auxiliary handle being completely hollow and having an inlet communicating with the protective hood so as to carry motor cooling air which has left the housing and passed the protective hood for the tool and then flows into the inlet of the auxiliary handle carrying debris and through the auxiliary handle and out of the latter, so that the auxiliary handle is operative for damping a flow noise of the air from the electric motor, from a motor-cooling fan and from the tool.
