Anti-vibration system reduces operator fatigue. Rear hand guard reduces the risk of injury, as well as providing wide area for foot placement during starting. Spark arrestor muffler has large baffles which reduce noise level. Smooth, clean design has no rough edges to snag on clothing or brush. Replacement chains are available.
