Abstract

A handle assembly for a power tool includes a main handle having a first end configured to couple to the power tool and a handle bar having a first end coupled to the main handle. The handle bar has an isolation bushing positioned at a first vibration dampening point and configured to dampen vibrations transmitted between the main handle and the handle bar. A vibration dampening assembly couples the handle bar to the main handle at a second vibration dampening point and is configured to further dampen vibrations transmitted between the main handle and the handle bar. The vibration dampening assembly includes a collar that encircles the main handle and a pair of annular resilient member positioned between the collar and the main handle. The collar defines a pair of circumferential grooves that receive the annular resilient member, and the resilient members are configured to be compressed into the circumferential grooves such that dampening of vibrations and maneuverability of the power tool varies as the resilient member is compressed.
