Abstract:
A hand-held power tool includes a pneumatic percussing mechanism (3) located in the power tool housing (2) and having an anvil (5) and a percussion piston (4) for applying blows to the anvil (5), and at least one oscillation damper (6, 6′) including an oscillation damping mass (7, 7′), at least one spring (8a, 8a′) for compressively preloading the damping mass (7, 7′) against the power tool housing (2), and an axially displaceable excitation member (9) for actively exciting the oscillation damper (6, 6′) in response to the anvil (5) occupying an operational position.
