Features:

  • 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 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.
  • 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.
  • Single-lever master control
    All important functions such as start, choke, throttle and stop are operated via a single lever.
  • Side-mounted chain tensioning
    The tensioning screw is located on the side of the chain saw through the sprocket cover. Chain side tensioning allows the saw chain to be retensioned effortlessly, avoiding any contact with the sharp chain.
  • 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%.
  • Tool free fuel caps
    Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.
  • HD2-Filter
    This air filter keeps even the finest dust away from the engine, ensuring a particularly long service life. Thanks to special material, the filter can be washed clean, for example with STIHL Varioclean and warm water.
  • Long-term air cleaner system with HD2-Filter
    The longlife air filter system 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 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.
