With dependability and an anti-vibration system, this mid-range chainsaw's fuel-efficient engine increases run time between refuelings by 20% compared to the previous model. A high-performance, fuel-efficient chainsaw. Great for felling, firewood cutting and storm cleanup. Another high-tech STIHL chainsaw, the MS 291 is built around one of our new fuel-saving engines with longer run times and lower emissions. And with an advanced pre-separation air filtration system, your air filter can last up to five times longer. Another great feature is an advanced anti-vibration system to reduce user fatigue. STIHL engineering is to thank for this high-powered, high-tech, low-maintenance chainsaw. It is truly a force to be reckoned with. Features Bumper Spikes These spikes prevent pull-in and provide better control, making cutting easier. Spark Arrester Muffler Large baffles reduce noise level and contain a screen designed to reduce the emission of sparks. Toolless Fuel and Oil Caps with Retainers Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen. Pre-Separation Air Filtration System This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance. Side-Access Chain Tensioner The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw. Advanced anti-vibration The advanced anti-vibration system makes the product more comfortable to use and reduces operator fatigue. Master Control Lever™ The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position. Throttle Trigger Lockout This safety feature must be depressed before the trigger can be activated. High-Tech Polymer Housings Housings are lightweight, withstand greater impact, and are corrosion-resistant. Powerful, Yet Lightweight Built for lightweight durability and packed with features, this powerful chainsaw is ideal for frequent use and tasks around the home.
