The MS 211, a low vibration chain saw powered by a low emission and fuel-efficient stratified scavenging engine, features a pre-separation air filtration system that moderates upkeep by extending the cleaning life of the air filter. It comes equipped with a carburetor preheat shutter for summer/winter operation. This saw is perfect for felling small trees, sawing firewood around the home or farm, and is part of STIHL’s new generation of fuel-efficient, environmentally friendly chain saws.
