Abstract
A hand-held power tool includes a main handle, a percussion mechanism striking along a percussion axis, a counter mass displaceable along an oscillation axis which is inclined to the percussion axis and biasing elements for preloading the counter mass to a rest position on the oscillation axis. The counter mass is arranged such that the rest position is closer to the main handle than the center of gravity is to the main handle.
