Standard features

 
  • Reduced-emission engine technologyZoom
    Reduced-emission engine technology

    The STIHL 2-MIX engine is both powerful and environmentally friendly. The exhaust emissions are separated from the unburnt gas. This minimises scavenging losses (the percentage of the mix that is discharged without burning), while increasing performance and reducing fuel consumption.

  • 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: lower consumption and high torque across a broad rpm range.

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

    The innovative long-life air filter system greatly extends the service life of the filter. Air routing removes larger particles of dirt, meaning the actual filter has less to do. So the saw can be used for longer without having to clean the filter.

  • STIHL anti-vibration systemZoom
    STIHL anti-vibration system

    Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.

  • Tool free fuel capsZoom
    Tool free fuel caps

    Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.

  • Decompression valveZoom
    Decompression valve

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

  • CompensatorZoom
    Compensator

    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 Ematic-SystemZoom
    STIHL Ematic-System

    The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption up to 50%.

  • Side-mounted chain tensioningZoom
    Side-mounted chain tensioning

    The tensioning screw is located on the side of the chainsaw through the sprocket cover. Chain side tensioning allows the saw chain to be retensioned effortlessly, avoiding any contact with the sharp 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

    Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand.

 
 

Additional features

  • STIHL ElastoStartZoom
    STIHL ElastoStart

    STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.
