Stihl Chainsaw MS 311

• The STIHL MS 311 petrol chainsaw is the ideal tool for firewood collection in medium-sized areas
• Farmers and horticultural specialists, in particular, will find this powerful chainsaw a valuable asset
• The STIHL 2-MIX engine delivers an impressive power output of 3.1 kW (4.2 hp). The pre-separation extends operating time by removing coarser particles before they reach the filter, thus reducing the cleaning frequency
• By installing the optional HD2 air filter, the STIHL MS 311 petrol chainsaw is equipped with a long-lasting air filtration system
• To protect muscles and joints, the STIHL anti-vibration system reduces engine vibrations. These features will help you work more efficiently with the STIHL MS 311 petrol chainsaw: The decompression valve reduces the force needed to pull the starter rope. This makes starting easier and protects the engine. The single-lever operation allows you to keep your right hand on the handle at all times, making use particularly comfortable and safe. To ensure the chainsaw is always properly lubricated, the STIHL Ematic system delivers chain oil exactly where it’s needed. This also results in reduced oil consumption

EQUIPMENT

Long-life air filter with pre-filtering
This innovative system significantly extends the filter’s service life. Thanks to the pre-filtering, it removes coarser dirt particles, easing the workload of the actual filter. The chainsaw can operate longer without needing the filter to be cleaned compared to a chainsaw without this type of filter.

Adjustable oil pump
Different cutting lengths, wood types, and working techniques require varying amounts of oil. The adjustable oil pump allows precise regulation of the oil flow rate according to needs. It is possible to reduce the oil supply by up to 50%.

STIHL 2-MIX engine
The STIHL 2-MIX engine is both powerful and economical. The separation of exhaust gases from inert gas minimizes unburned particle emissions, increasing performance and saving fuel.

Compensator
Ensures a constant fuel-air mixture even when the air filter becomes dirtier.

QuickStop Chain Brake (Q)
Special precisely positioned damping zones reduce the transmission of vibrations from the engine and chain to the handle and grip.

Ematic Chain Lubrication System
Depending on the type of guide bar and wood, the STIHL Ematic system reduces chain oil consumption by up to 50%. It consists of an Ematic guide bar, Oilomatic chain, and an adjustable low-flow oil pump. This ensures the lubricant is delivered precisely and with minimal loss exactly where it is needed.

Anti-Vibration System
Special precisely positioned damping zones reduce the transmission of vibrations from the engine and chain to the handle and grip.

Tool-Free Fuel Cap
Special caps for the fuel tank and oil tank allow for easy opening and closing without difficulty.

Side Chain Tensioner
The chain is tensioned laterally via the sprocket drum. This prevents any contact between the operator’s hand and the cutting chain.

Single-Lever Control
All functions such as starting, running, and stopping can be operated with one hand.

Decompression Valve
The decompression system automatically opens the intake valve. This absorbs pressure peaks and reduces the amount of force needed on the starter rope.
