A portable hand-guided work apparatus ( 1 ), such as a motor-driven chain saw, cutoff machine or the like, includes an internal combustion engine ( 2 ) and an air filter ( 10 ). At least one air channel ( 8 ) and an intake channel ( 7 ) are provided which fluidly connect the internal combustion engine ( 2 ) to the clean side of the air filter ( 10 ). The intake channel ( 7 ) is configured at least partially in a carburetor ( 9 ). The air channel ( 8 ) opens at an air channel opening ( 13, 13', 13 '') and the intake channel ( 7 ) opens at an intake opening ( 12 ) at the clean side of the air filter ( 10 ). Air channel opening ( 13, 13', 13 '') and intake opening ( 12 ) open spatially separate from each other at the clean side of the air filter ( 10 ). To prevent the entry of fuel into the air channel ( 8 ) from the intake channel ( 7 ), the intake opening ( 12 ) in the normal work position of the work apparatus ( 1 ), seen in the effective direction ( 17 ) of the gravity force, has an elevation offset (a, a', a'') relative to the air channel opening ( 13, 13', 13 '').
