Features

Standard features

  • COMFORTABLE CARRYING SYSTEM Zoom
    COMFORTABLE CARRYING SYSTEM

    FOR EFFORTLESS WORK. Thanks to the optimised weight distribution, the comfortable carrying system enables you to work with minimum fatigue and high comfort even during longer periods of use. The breathable backrest pad makes it comfortable to wear.

  • STIHL 4-MIX® ENGINE Zoom
    STIHL 4-MIX® ENGINE

    FOR FANTASTIC ENGINE POWER WITH LOW MAINTENANCE. The STIHL 4-MIX® engine is a four-stroke engine that does not require any oil circuit components, thanks to refuelling with an oil and gasoline mix. That’s why it’s more compact, more lightweight, and requires less maintenance than conventional four-stroke engines, while at the same time being powerful and offering a comfortable sound pattern. STIHL 4-MIX® engines comply with the European Stage V emissions directive.

  • 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.

  • Anti-vibration system Zoom
    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 Zoom
    Multi-function control handle

    Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.
