    Reduced-Emission Engine Technology - Caring for Nature

    Pre-Separation Air Filtration System
    This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

    Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

    Toolless fuel and oil caps with retainers
    Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.
  • Zoom
    Side-Access Chain Tensioner
    The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
  • Zoom
    Decompression Valve
    The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.

Important Information
WARNING! The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus (Q) additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.
* The actual listed guide bar length can vary from the effective cutting length depending upon which power head it is installed.
Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty. Learn More…

Rated 4.7 out of 5 by 115reviewers.
Rated 5 out of 5 by Excellent Saw I bought this saw after reading many reviews on the internet and talking to alot of different people. It has very good power and cuts better than any saw I have ever owned or used. The large chain makes quick work of larger trees and will even rip cut when necessary to split extremely large pieces in halves or quarters. I highly recommend this saw to anyone who cuts alot of wood. October 22, 2012
Rated 5 out of 5 by Great saw Great saw, had it about a year, full time logging and cordwood, saws seen well over 200 cord now and never had an issue with it. February 1, 2016
Rated 5 out of 5 by great saw , reliable, cuts great does a great job , starts easily, very reliable would buy another if I lost this one January 17, 2016
Rated 5 out of 5 by Great Mid Range Saw I own many chainsaws and I am completely happy with this saw. The time between refueling is longer than my MS 291. That alone make s it my first choice of saws to grab. Stock options only provide for a 16 or 20 inch bar length. But you can get after market bars and chains up to 36" I have not gotten one yet but I believe it would have enough power to push it. December 26, 2015
Rated 5 out of 5 by Extreme Versatility! I have had my MS311 for a few months now. I have used it for a felling saw, to a limber, and everything in between with zero fight. Best saw I have owned! I intend to have many more Stihl additions to my tools. December 9, 2015
Rated 5 out of 5 by 100% an excellent chainsaw I bought the Stihl MS 311 for my lawn and landscape business it does the job just fine I found a lot of Stihl products they're always very good at their job I've used lots of brands and I recommend Stink 100%. Please ignore the negative reviews nine times out of ten they are misusing the product the other time maybe there's a factory defect which if you're buying from an authorized dealer with the warranty by the pack of oil and get 4 years instead of 2 and you won't have any problems December 9, 2015
Rated 1 out of 5 by Very powerful saw the 25% of the time that it actually will start. Since new, purchased in 2011, will not reliably start. Have had it in for service at least yearly without relief. December 2, 2015
Rated 5 out of 5 by This saw is a monster My brother and I went into a Stihl shop and both walked out with brand new saws. He bought the 391, and I bought the 311. Mine keeps up with his just fine. There is very little noticeable difference between the two. This saw is a monster! October 29, 2015
