STIHL 4-MIX engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly, quietly and more easily
Anti-vibration system
Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines 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.
