STIHL 4-MIX® engine. You can always rely on STIHL to set new benchmarks, this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX® engine, which runs on a fuel-oil mix like a 2-stroke, offers the benefits without the compromises of 4-stroke power. This technology provides fast acceleration, more power, added torque, lower noise, reduced emissions, and increased fuel efficiency to complete jobs quickly, quietly, and easily.

Decompression system. The decompression valve allows some of the compression pressure in the cylinder to escape, requiring less force on the starter rope.

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 developed an effective anti-vibration system that dampens the oscillations from the machine's engine, significantly reducing vibrations at the handles.

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

Ergonomic harness with hip belt. The ergonomic harness with hip belt offers carrying comfort, with height and strap adjustment. The hip belt also enhances comfort when working for prolonged periods.
