The MS 311 Petrol Chainsaw is a full sized Chainsaw that can drive the larger 3/8 pitch saw chain - as used on our pro Chainsaws. It can handle felling firewood in medium density forests and is a great option for farmers. With our 2-MIX engine technology, you receive higher fuel economy for longer run times. The MS 311 also has larger fuel and oil tanks allowing you to work longer before refueling.
Your Chainsaw will require engine oil and bar lube. We recommend STIHL HP ULTRA TWO STROKE ENGINE OIL and STIHL SYNTH PLUS CHAIN LUBRICATION for your machine.

2-MIX EngineModern, powerful and economical engine. Provides fuel savings and reduced emissions.
Anti-vibration SystemVibrations from power tools can lead to negative effects on blood vessels. STIHL has developed a system for minimizing the levels. This also helps reduce operator fatigue and provides a more comfortable working experience.
Ematic Chain Lubrication SystemA reservoir holds bar oil until it is picked up by the passing chain. This achieves maximum lubrication resulting in longer wear and less oil consumption.
Single Master Control LeverAll the important functions of start, choke, throttle and stop are operated via a single lever.
Easy Open Fuel and Oil TanksSpecial caps on the fuel and oil tanks allow for easy opening and re-fueling.
Reduced Air Filter MaintenanceA pre-separation filter system is used to clean the air before it reaches the main air filter. The benefit is that maintenance of the machine is reduced.
Side Chain TensionerThere is a tensioning screw on the side of the Chainsaw through the sprocket cover. This is easy to use and removes the need for contact with the sharp saw chain.
Controlled-delivery Oil PumpDifferent bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job.
Decompression ValveThe decompression valve, vents compression in the cylinder to reduce the cranking effort.
