Standard features

  • HD2-Filter Zoom
    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 Variocleanand warm water.

  • Decompression valve Zoom
    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.

  • STIHL M-Tronic (M) Zoom
    STIHL M-Tronic (M)

    For a cold start, the STIHL M-Tronic only needs one start position on the combi-lever. After starting, you can immediately power up to full speed. The amount of fuel required is precisely calculated by the system and supplied as needed. Otherwise, start in position I as usual.

  • STIHL anti-vibration system Zoom
    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.

  • STIHL 2-MIX-Motor
    STIHL 2-MIX-Motor

    Der sparsame STIHL 2-MIX-Motor mit 1-in-4-Kanaltechnologie überzeugt mit einem hohem Drehmoment über einen weiten Drehzahlbereich. Dabei spart die Motorsäge bis zu 20% Kraftstoff im Vergleich zu leistungsgleichen STIHL Zweitaktmotoren ohne 2-MIX-Technologie. Der Abgasausstoß wird um bis zu 50 % gesenkt.

  • Compensator Zoom
    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.

  • Captive bar nuts Zoom
    Captive bar nuts

    Bar nuts held captive in the sprocket cover will not get lost when changing over the cutting attachment.

  • Controlled-delivery oil pump Zoom

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%.
