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.

  • 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.

  • 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.

 
 

Additional features

  • Long-term air cleaner system with HD2-FilterZoom
    Long-term air cleaner system with HD2-Filter

    The longlife air filter system with cyclone pre-separator has a service life up to five times longer than the previous model. The newly developed HD2 filter is made from a water- and oil-repellent polyethylene filter material. It has up to 70 per cent finer pores than fleece and it is easy to clean. The PET-coated round filter cartridge with quick-release lock enables the filter to be fitted and removed in next to no time.

  • 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.
