Standard features

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)
2-in-1 conversion mechanism

The universal SR 450 can be switched easily from spraying to dusting at the turn of a handle. No need for a separate conversion kit or specialist technical skills.
Grid

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.
Metering system with easy metering lever

The large metering lever for dusting or spraying granules is just below the control handle. With just one movement, you can switch the flow of powder on and off, and set the exact concentration in fine intermediate stages.
