Features

Standard equipment

  • STIHL ElastoStart Zoom
    STIHL ElastoStart

    STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.

  • 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
