Model Features

  • Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

    Indicates products that are built in the United States from domestic and foreign parts and components.

    More information

  • 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.

    More information

  • 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.
  • 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.
  • 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.
  • 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.

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 based on which powerhead it is installed on.

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…

WARNING! Improper use of any power tool may cause serious or fatal injury. Read, understand and follow carefully the operating and safety instructions in your instruction manual before using such products.

Reviews

MS 311 is rated 4.7 out of 5 by 152.
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Power and Comfort in a great package! I used my new saw for two hours. It had the power I required to cut whatever I needed it to. The anti-vibration feature allowed me to continue cutting without fatigue. The extra capacity full tank permitted me to cut without frequent refills.

Rated 5 out of 5 by from Great saw for the money! I grew up using my Dads 032 with a 20 inch bar. That saw always started and ran good; even after my brother fell a tree on it! This 311 has a lot more power and my dealer gave it to me with a 28 inch bar. always starts and runs even if it sits a while between uses. Never wonder if it'll start. I use it commercially in a cemetery maintenance district. I have 46 acres to maintain and am the only employee. Needless to say, I cant wonder if something is going to start and run; i need it to work when I do and this saw does. It's a bit tip heavy with the 28 inch bar but I don't notice a lack of power and the extra length is worth it to me. I don't have to bend much to cut something at ground level.

Rated 5 out of 5 by from Excellent all around saw Got rid of my other brand orange saw years ago, ran into an excuse to buy a new saw. Buddy offered to trade me a new saw of my choice in exchange for doing some mechanics work for him. He recommended a stihl, so I decided to try it. Got this saw and lover it. Great power,features, always starts!

Rated 5 out of 5 by from Reliable, powerful, durable I bought my MS 311 about a year ago and it has performed beyond all expectations. It's lightweight for the amount of power it has, always fires right up, is tough as nails and makes short work of any task I've used it for. I cut several cords of firewood a year to heat our home and it has never let me down. Really, really great product.

Rated 5 out of 5 by from Great mid sized saw I bought this saw to tackle larger wood cutting jobs. This saw has been wonderful and many people complain about the power to weight and difficulty starting. I have to disagree with them, stone cold it has never taken more than 4 pulls to start usually 3, and as far as weight it is not bad truly. It has plenty of power to pull the 20" bar buried into a 40" oak without a hiccup. I have run the snot out of this saw for a month now and occasionally it wears a 25" bar with a skip chain. I can honestly say it pulls that just fine. I would recommend this saw to anyone wanting something in this price and size point. The extra half hp over the husky is a nice too.

Rated 5 out of 5 by from good addition It takes so much less effort to cut and having the 20inch bar helps with big trees. I have been using a MS 250 for everything which wears me out. Having a bigger saw and a smaller has made life so much better. Heavy weight helps with cutting too and less vibration..
