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.
-
Ergonomic harness
Evenly distributes the weight between the user's shoulders, back, hips and upper thighs. With soft padding for increased comfort during prolonged use and when working on large areas.
-
Decompression system
The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.
