Standard features

  • STIHL 4-MIX® engineZoom
    STIHL 4-MIX® engine

    You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX® engine, which runs on a fuel-oil mix just like a 2-stroke, offers the benefits without the compromises of 4-stroke power. STIHL 4-MIX® engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly, quietly and more easily.

  • Decompression systemZoom
    Decompression system

    The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.

  • Air filter with long service lifeZoom
    Air filter with long service life

    The easily accessible paper filter with a long service life means it can go for long intervals without changing. (similar to illustration)

  • Manual fuel pump (Purger)Zoom
    Manual fuel pump (Purger)

    A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

  • Bike handleZoom
    Bike handle

    When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas and thus reducing fatigue.

  • Anti-vibration systemZoom
    Anti-vibration system

    Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

  • Multi-function handleZoom
