Equipment and Function

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

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.

Carrying system

Mistblowers are equipped with a practical carrying system. Weight is evenly distributed across the shoulders and back to ensure maximum user comfort.

Multi-function control handle

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

14-litre tank with large filler opening

The 14-litre container offers exceptional capacity. You can work for longer before having to refill. Filling is quick and clean with the large filler opening. Spillages are kept to a minimum and the container is easy to clean. (similar to illustration)


With the three grids that you can assemble, you can change the spray jet’s shape and direction. Taper grids, diffraction grating and double diffraction grating are standard features.

STIHL 2-MIX-Engine

The device is equipped with a modern, low-noise and low-emission STIHL 2-MIX engine. The STIHL two-stroke engine with 2-MIX technology provides powerful performance, plenty of torque, and fuel savings of up to 20% compared to STIHL two-stroke engines in the same performance class without 2-MIX technology.
