<p>The damper (1) has a damping mass (3), and a spring (4) for axially and compressively preloading the mass against a power tool housing (5). A spring (9) is provided for axially and compressively preloading the mass against the housing. A user-operated switching element (8) is displaceable between a position in which the mass is axially and compressively preloaded against the housing by the spring (4) and another position in which the element connects the mass with the spring (9) so that the mass is preloaded against the housing by both the springs.</p> |
