    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.

    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.

    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 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…

Rated 4.6 out of 5 by 142reviewers.
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 One powerfull saw Enough power to handle any of my cutting needs. I do have to be careful not to flood the engine. 1 pull on choke should do it. No more than 2. October 25, 2016
Rated 5 out of 5 by Excellent saw for taking care of my trees I own about five acres of trees and find myself trimming and cutting and felling trees frequently. You'd think I would have ran out of trees by now. No such luck. I bought this saw to take over the felling chores and it does this well. I also use it for cutting railroad timbers. It starts easily enough as long as you follow the instructions in your manual; you did read it, right? I seem to be using it weekly and that may contribute to the easy starting. If you're just limbing this saw is probably not ideal, it is heavy and powerful, but if you have to cut them down, aren't a professional, and don't want to spend a fortune, then this is your saw.

Rated 5 out of 5 by Ms311 I bought the 311 little hard to start but when it starts it runs good! October 17, 2016
Rated 4 out of 5 by Heavy, but happy. I use this saw for many different applications. Thus, the reason why I got a 311. I wanted the power if I needed it. But, the weight is heavy with the 25" bar. Other than that, great saw. September 21, 2016
Rated 5 out of 5 by This saw is great! It is everything I was told it would be and more. Cuts really nice and is easy to use. September 8, 2016
Rated 5 out of 5 by Great power This saw has been good to me over the past year. Even when I'm not using it still starts under 5 pulls and has great power handling a 20" bar cutting large oak. September 4, 2016
Rated 5 out of 5 by Excellent product!!! We purchased the MS-311 after talking to our local dealer. Given the sze of our property he recommended the larger MS-311. We previously borrowed another brand from a friend and it had difficulty starting at our house which is at 7300'. I told the dealer where we located and they adjusted the engine to the higher altitude, 1800' above the dealership. They even offered to come up to the house if there were problems. We have about 30 hours on it now and it is wonderful. It starts everytime with 3-4 pulls when cold and 1-2 when warm. We have since purchased a Stihl weedeater/brushcutter and blower. All great products and well worth the money. August 30, 2016
