Highlights
Powerful engine for medium-sized stands
The 3.1 kW STIHL 2-MIX engine delivers the cutting performance needed for regular firewood cutting in medium-sized stands.
Decompression valve
When starting, the valve releases some of the compressed mixture from the cylinder. This significantly reduces the pulling force needed on the starter rope and protects the starting system.
Long-life air filter system
Pre-separation removes coarse particles before they reach the filter itself. With the optional HD2 filter retrofit, filter life doubles compared with previous models.
Carburettor preheating
Preheated intake air prevents the carburettor from icing up at low temperatures. This keeps the MS 311 reliably ready for use in winter too.
Single-lever control
Cold and warm start, run and stop are controlled with a single lever. Your right hand always stays on the handle, making operation safer.
Comfortable working
The STIHL anti-vibration system significantly reduces strain on arms and hands during longer work sessions.
