    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…

STIHL Dealer Days are Happening Now!

MS 311 is rated 4.6 out of 5 by 210.
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 This product is very user friendly. I purchased several acres of heavily wooded property in Arkansas and I was in need of a saw that I could rely on to get the job done. Of course I thought of STIHL as I have always heard they were great saws. I went to my local dealer who was very helpful and recommended the MS 311 after I explained my situation. I have operated many different chainsaws in my day and none of them can hold a candle to this saw. The performance of this saw is excellent. The saw starts easily and runs perfectly from the second its started, seems like it doesn't even need to warm up. So far I have cut down about an acres worth of trees most of them being old cedar and haven't had a single issue with the saw. The saw does have some weight to it but I think thats to be expected with a little bigger saw. The power is excellent and with the ⅜" chain makes short work of anything in its way.

Rated 4 out of 5 by from Very good saw This saw (ms311) seems to be a really good saw. I have owned a multitude of stihl saws over the years and I haven’t been unhappy with any of them. The 311 has a lot of great features like a decompression valve for easy starting. It has an anti vibration feature which is nice if you’re cutting a lot of wood. I wanted a saw that had lots of power and this saw seems to have that. There are a few cons that I’ve noticed. The throttle response is kind of lacking. To be honest I think between all the emmision stuff and the constricted muffler it kills a lot of power and the main reason the throttle response isn’t quite as crisp as my older saws. The other draw back I found was the weight of the saw. Obviously when you buy a big saw like this it’s not gonna be light but if you carry this saw around all day, you will feel it. Other than that I would say that this is a great saw for a home owner that needs a power. I would recommend it.

Rated 5 out of 5 by from Amazing chainsaw Awesome saw looks great built well and runs amazing. I have ran ever other brand avaliable and nothing bets stihl the last for ever. I have had this saw for 5 years with no problem what so ever.

Rated 5 out of 5 by from Best saw i have ever used I have ran many chainsaw for example i use to be a logger and ran anywhere from a 250 to a 660 sthil and my favorite saw was the 362 but after buying my 311 i wouldnt go back to any other saw it glt the power and is comfterble i cut big timber almost ever day and this saw just wont die

Rated 1 out of 5 by from Used twice and the throttle stuck I usually love these saws, but I cannot give a glowing review on something that broke down after only using it two times. The throttle stuck and my saw is now sitting where I purchased it a little over two weeks ago.
Date published: 2018-03-26
Rated 5 out of 5 by from Excelent Chainsaw, highly recommended I bought this chainsaw as my other smaller saw was not up to the task of the larger trees I had to handle. With the 24 inch bar I am handling the 40" diameter oak trees like they were soft butter. This saw has not even slowed down to take a breath. 8 cord of wood in two weekends and this thing is ready for more. I do recommend the carbide chain if you are doing large capacity cutting, but of course if you are doing that much like I am, you probably already know that. I would recommend this saw to anyone that needs to step up to a larger 3/8 chain and longer bar. A real workhorse without getting into the real heavy chainsaws that are an arm workout.

Rated 5 out of 5 by from Easy to start Love my new chainsaw. Now i dont have to borrow from family members. It starts easy every time i use it. It has the power i need to get the job done.
