Abstract (en)
[origin: EP2653270A2] The power tool has a pneumatic rammer (6) that is driven by a motor (5) around a hub. An exciter (12) is driven between tool far dead center and tool near dead center. A pneumatic chamber (15) is locked by exciter. A racket (13) is moved between tool distal reversal point and percussion point. The movement of racket is coupled to the movement of the exciter. The pressure in the pneumatic chamber is increased by damping device (39), when the exciter is less than 10% of the stroke during movement towards the tool far dead center. An independent claim is included for control method of hand-held power tool.
