The STIHL MS 391 18″ Petrol Chainsaw is a versatile and powerful petrol chainsaw engineered for serious woodcutting tasks, from harvesting firewood to felling medium-sized trees and agricultural timber work. Powered by a 64.1 cm³ 2-MIX engine, it delivers strong torque across a broad speed range while offering up to 20 % better fuel efficiency and 50 % lower emissions than previous models, making it both efficient and eco-friendly.
Designed for user comfort and productivity, the MS 391 includes a manual decompression valve for lighter, easier starting, an anti-vibration system to reduce fatigue during extended use, and side-mounted chain tensioning for quick, safe adjustments. The Ematic chain lubrication system ensures precise oil delivery to the bar and chain, reducing oil consumption and extending component life.
With a responsive powertrain, tool-free fuel and oil caps for fast refills, and rugged STIHL build quality, the MS 391 is ideal for landowners, farmers and professionals seeking reliable performance and efficiency in every cut.
