Another high-tech STIHL chainsaw, the MS 291 is built around a fuel-saving engine with long run times and low exhaust emissions. The advanced pre-separation air filtration system perceptibly relieves the downstream filter components, increasing the life of your air filter. Another great comfort feature is an anti-vibration system to provide you with a more comfortable working experience. It is truly a force to be reckoned with.
