ECHO CS-310 CS-352 CS-353 ES SHINDAIWA 340S Chainsaw Rubber AV Mounts

Rubber anti-vibration (AV) mounts fits Echo CS-310, CS-352, CS-353 (ES) and Shindaiwa 340S chainsaws, replacing part number V420-001790. The rubber AV mounts are bonded isolation buffers positioned between the engine unit and the handle frame, absorbing engine and cutting chain vibration before it reaches the operator’s hands. When the rubber hardens, cracks or collapses, vibration passes directly through the chassis to the handles — increasing operator fatigue and the risk of long-term hand-arm vibration injury. Fitting replacement mounts restores effective vibration isolation and brings the saw back within safe operating levels.
