MS 291 Petrol Chainsaw

A true all-rounder for forestry, estate and fire-wood duties, the MS 291 blends a high-torque 55.5 cm³ 2-MIX engine (2.8 kW / 3.8 hp) with STIHL’s long-life pre-separation air-filtration and Ematic lubrication systems, stretching service intervals while reducing oil consumption. The 390 ml fuel tank delivers around 45 minutes of cutting, and the 240 ml oil tank is sized to empty at the same time. Professional anti-vibration buffers hold handle vibration to about 4.5 m s⁻², keeping hands comfortable on long sessions.
