The MS 391 chain saw features a stratified charge engine that reduces fuel consumption and emissions, while providing significantly more power than others in its class. Combined with an exclusive long-life air filtration system, advanced anti-vibration system, tool less fuel and oil caps with retainers and a side-access chain tensioner, this is an environmentally conscious pick for mid-range users.
