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.

Multi-function control handle

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

Carrying system

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