    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.

  • Anti-vibration system
    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 control handle

  • Ergonomic harness
    Ergonomic harness

    Evenly distributes the weight between the user's shoulders, back, hips and upper thighs. With soft padding for increased comfort during prolonged use and when working on large areas.

  • Decompression system
    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.
