Abstract
A percussion tool includes a housing, a percussion mechanism including a striker supported for reciprocation in the housing along a first axis, and an anti-vibration system for attenuating vibration in a direction of the first axis. The anti-vibration system includes a linkage coupling the percussion mechanism to the housing. The linkage permits relative movement between the housing and the percussion mechanism along the first axis. The anti-vibration system also includes a counterweight supported by the percussion mechanism for relative movement therewith along a second axis that is parallel with the first axis. The counterweight reciprocates out of phase with the striker to attenuate vibration in the direction of the first axis.
