  3. MS291 56cc engine, 20" bar and 3/8 75LP heavy cutting chain makes quick work of farm, landscaping and domestic jobs!
  4. MS291's anti vibration system works amazingly. Vibrations are directed away from the handles meaning you can work the saw for longer with out fatique.
  5. MS291 build design makes it very easy to maintain, tune up and service making it a reliable tool out on the job. 

Durable 2.8kW petrol chainsaw is a practical all-rounder for farmers, landscapers and gardeners. With the economical 2-MIX engine, fuel consumption is reduced by up to 20% and emissions are cut by up to 50%. Featuring STIHL's long-life air filter system with pre-separation and professional anti-vibration technology, the MS 291 sets a new standard for this type of saw.

  • STIHL 2-MIX engineZoom
    STIHL 2-MIX engine

    The two-stroke engine with STIHL 2-MIX technology saves up to 20 % of fuel and reduces emissions by up to 70 % compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.

  • Carburettor heating (V)Zoom
    Carburettor heating (V)

    By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

  • Side-mounted chain tensioningZoom

    Side-mounted chain tensioning makes it easy to tension the chain safely.

  • Pre-separation air filtration systemZoom
    Pre-separation air filtration system

    STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.

  • Advanced combustion technologyZoom

    Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.

  • CompensatorZoom

    This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

  • STIHL anti-vibration systemZoom

    Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles. The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.

  • STIHL Ematic SystemZoom
    STIHL Ematic System

    Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50 %, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.

  • Single-lever master controlZoom
