The STIHL MS 311 petrol chainsaw is the ideal tool for obtaining medium-sized firewood. With these powerful chainsaws, farmers, gardeners and foresters are well prepared for their work. The STIHL 2-MIX engine has a power of 3.1 kW (4.2 hp).
The air cleaning system with pre-filter extends the working time before the saw requires servicing, because coarse particles are removed before they reach the filter, and the filter can be cleaned less frequently. You can additionally equip yourself with the optional HD2 air filter, creating a long-life filter system. To protect muscles and joints, the STIHL anti-vibration system reduces engine vibrations. Further features will also help in efficient work with the STIHL MS 311 petrol chainsaw:
The decompression valve reduces the force required to start the device. This makes starting easier and protects the engine.
Control via a single lever means you always keep your right hand on the handle, making the saw comfortable and safe to operate.
The side chain tensioner enables safe, easy and quick tensioning and replacement of the chain. The tensioning screw is accessible from the side through the chain drive cover.
It allows precise, needs-based lubrication. The E marking guarantees the supply of the right amount of oil in all working conditions. Professionals dose precisely. The pump allows oil consumption to be reduced by up to 50%.
The adjustment system in the carburetor, the compensator, through pressure equalization ensures that despite increasing air filter contamination, engine power, exhaust quality and fuel consumption remain almost unchanged for a long time. Therefore, the air filter only needs to be cleaned after a clear drop in parameters. This allows long periods of maintenance-free work.
The STIHL Ematic system consists of the STIHL Ematic or Ematic S guide bar, the STIHL Oilomatic saw chain and an oil pump with adjustable flow. It guarantees that chain oil reaches where it is needed for lubrication. This allows oil consumption to be reduced by up to 50%. When working in very dusty conditions or using long guide bars, the oil quantity can be easily and quickly increased at any time thanks to the new oil pump system.
STIHL chainsaws equipped with a carburetor preheating system are reliable even when it is cold outside: in winter operating mode, heated air flows around the carburetor. This solution effectively prevents carburetor icing.
In four passage channels, the fuel-air mixture is swirled before ignition. This ensures better fuel combustion and significantly increases engine efficiency. Result: lower fuel consumption and high torque over a wide speed range.
The decompression valve makes starting the device easier. Opening the valve during start-up releases part of the compressed mixture from the cylinder. This protects the starting system and requires less force on the starter rope.
This 2-stroke engine is designed to require little maintenance and consume fuel even at high power. A mixture of gasoline and engine oil should be used as fuel. The STIHL 2-Mix engine meets the requirements of the strict EU exhaust emission directive, level V.
When increasing the device's power, vibrations are generated that are particularly noticeable in the handle area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area, and thus to the user's body. Effect: The device sits more comfortably in the hand, and work is much less tiring.
