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

This backpack sprayer is 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.
