<p>An electric hand-held power tool is described that has a machine housing ( 11 ) with an integral dust-ejection connection ( 15 ) and a dust collection container ( 16 ) attached thereto. To ensure, when working with the electric hand-held power tool, that the dust collection container ( 16 ) is emptied in time when full, a fill level indicator is provided that indicates, at the least, the maximum amount of dust allowed in the dust collection container ( 16 ). The fill level indicator ( 20 ) is preferably integrated in the machine housing ( 11 ) and includes a pressure sensor ( 21 ) that measures the pressure in the dust-ejection connections ( 15 ), and a display unt ( 22 ) that is actuated as a function of the pressure measured (FIG. 1 ).</p> |
