摘要:
A hand-held work tool has a drive motor and at least two cutting blades, at least one of which is driven back and forth by the drive motor. A first cover strip, which has at least keyhole-shaped openings, is arranged on a longitudinal side of one of the cutting blades. There are at least two fastening elements provided which project through the cutting blades and the first cover strip. Each opening has a slip-on portion and a fixing portion. The fixing portions, at least in part, engage behind the fastening portion of the associated fastening element with the first cover strip in the fixed state. The sides of the fixing portions of adjacent openings facing the slip-on portion are at a first spacing from one another. The sides of the fixing portions of adjacent fastening elements facing the fixing portions are at a second greater spacing from one another.
