Stihl Gas Chainsaw MS 391

$779.95

The MS 391 chain saw features a stratified charge engine that reduces fuel consumption and emissions, while providing significantly more power than others in its class. Combined with an exclusive long-life air filtration system, advanced anti-vibration system, toolless fuel and oil caps with retainers and a side-access chain tensioner, this is an environmentally conscious pick for mid-range users.

Standard features

  • Reduced-emission engine technologyZoom
    Reduced-emission engine technology

    2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

  • STIHL anti-vibration systemZoom
    STIHL anti-vibration system

    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.

  • Advanced combustion technologyZoom
    Advanced combustion technology

    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.

  • 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.

  • Tool free fuel capsZoom
    Tool free fuel caps

    Special caps to open and close the tank cap quickly, easily and without tools.

  • Decompression valveZoom
    Decompression valve

    The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

  • 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.

  • Side-mounted chain tensioningZoom
    Side-mounted chain tensioning

    The tensioning screw can be found on the side of chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.

  • Single-lever master controlZoom
    Single-lever master control

    All important functions such as start, choke, throttle and stop are operated via a single lever.

  • Controlled-delivery oil pumpZoom
    Controlled-delivery oil pump

    The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.
