Standard features

  • 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.

  • 14-LITRE CONTAINER Zoom
    14-LITRE CONTAINER

    WITH LARGE FILLER OPENING. This 14-litre container allows you to work for longer without interruption, Because its large capacity means you do not need to refill as often. When the time does come, the large filler opening makes refuelling quick and easy, while also reducing spillage. The tank is also easy to clean thanks to the large opening.

  • 2-IN-1 CONVERSION MECHANISM Zoom
    2-IN-1 CONVERSION MECHANISM

    EASY CHANGE OF MODE. Thanks to the 2-in-1 conversion mechanism, to quickly switch from spraying to dust application you just need to remove, turn and reinstall the tank. This can be done in just a few simple steps without the need for tools.

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.

  • AIR DIRECTING MESH Zoom
