    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.

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.

Are You Ready for a STIHL?

MS 311 is rated 4.6 out of 5 by 217.
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 Great saw Been using a 36cc 16" saw for years. Finally ran into a tree it just couldn't seem to make it thru (not enough power, kept bogging down). Went to the local Stihl dealer and picked up a brand new MS 311. WOW! I know it's only 25cc's (or there about), but this thing ate thru a wet and partially rotten/partially petrified cottonwood tree like a hot knife thru butter (sorry about the cliche, BUT IT DID!). Very happy with the purchase and if I only had more trees that needed cutting... I'm having just too much fun with this thing!

Rated 5 out of 5 by from Incredible machine! My second Stihl chainsaw and I couldn't be happier. My first one was stolen and I tried to sneak by with a cheaper competitor. Big mistake! When I put this MS 311 to work it was incredible; I had forgotten how dependable they were. Don't compromise, get a Stihl

Rated 5 out of 5 by from Product is as strong as its name I just used this saw i bought a year ago. One blade and three tank refills filled my 18' trailer 3' high. So happy with my purchase I'm looking at buying another. For the size of the saw it was well balance which made cutting wood extremely easy.

Rated 1 out of 5 by from This saw has a flaw I am usually a fan of Stihl, having owned Stihl saws for the last 30 years. I bought this saw 2 years ago and kept it proper fuel and oil. Last week I started cutting a log and the saw died, something not normal for this saw. I restarted it thinking it was just cold, since I had just started cutting, it then popped and died again. Now there was no compression or spark. I checked decompression valve, it was fine, when I got home I pulled off the muffler and inside of piston was was badly scarred in one place, so a bearing or ring has broke and ruined the cylinder. The saw was not hot and had never ran hot so know not caused by fuel. I have looked online and this is a common problem it seems with this saw. Not sure if I will replace with another Stihl.

Rated 5 out of 5 by from Great product I bought this saw a while ago and have never had an issue. Excellent power and super realizable. I’ve had it sit for a a few months and it starts up no issues and runs all day. I plan on upgrading to a bigger saw soon and will still keep ole faithful for a back up.
Date published: 2017-12-13
Rated 5 out of 5 by from Powerhouse My son and I bought this saw from a local dealer about a year ago now and all I can say is wow! This saw is a bit bigger than what I normally use but we needed a bigger saw anyway and this fits the bill nicely. The 311 is packed with a ton of power and is great for all the bigger stuff we run into. Just a great saw in a great package. Stihl hit a homerun with this saw to say the least. It's a bit heavy but that's why we only use it on the bigger stuff. It cuts through it like a hot knife through butter. The 20" bar is perfect for our needs and if we needed to put a bigger bar on it it has the power to handle it and not slow down. If you're in the market for a little bit bigger saw than normal like a 261 size then this saw is worth a hard look. It just works great. It has an easy to get to ( even with gloves on ) compression release button for easy cold starts also. Just a well thought out package. I buy Stihl saws because when I need a saw I need a saw that works and works well. Nothing is more frustrating than having some tree work to do and the saw won't stay running or is a hassle to start. Buy a Stihl and put that issue behind you. With Stihl I get the job done cause the product starts easily and runs like it should. Makes the job a lot easier. We own a Stihl MS180 Mini Boss a Stihl MS 261 and a Stihl MS 311 and all are great saws and have served us well. I know everyone that reads this review may not find it helpful but if you are reading it it's probably because you already have a smaller saw and are looking something a bit bigger like we were to help with the bigger stuff and you're familiar with how saws work. Meaning you're not a beginner and this isn't your first saw purchase. The 311 is NOT a first saw purchase by no means it's a heavy load saw and should be used as such. Buy with confidence and know that this saw is ready to work and work hard. Thanks for reading.

Rated 5 out of 5 by from Great saw and reliable Great saw lots of power for cutting a few cords of firewood every year, only thing I don’t care for is the chain oil is not adjustable and I don’t think it has enough oil coming onto the chain. However I have taken it back to the dealer and they think it’s ok. Uses less then half the tank of oil to a full tank of fuel.

Rated 5 out of 5 by from This saw is very dependable and is a workhorse. I have purchased two MS-311's by Stihl, and I have nothing but good to say about them. I recommend this product to everyone I associate with. When it comes to chainsaws, Stihl is, by far, the best saw I ever used. The company seems concerned about user safety, and have done good things to reduce kickback.

Rated 5 out of 5 by from Superior Saw - A+ I purchased this saw about a year ago when I bought wooded property. I use the 20" bar for most everything and the 25" for stumps. It eats anything you put in its path! I give it a 99 out of 100 - it's a little hard to start after a month without use. This saw and a 193T saw is all you need!

Rated 5 out of 5 by from Great saw! Very dependable and has great power I've had the MS311 for a year now. I love it! This saw always starts when I use it, and it chews up trees quicker than a starving beaver. The power is great. I would definitely buy another one, but as dependable as it is, I won't need one for a long time. I would definitely recommend this saw for anyone who uses this saw for around the house farm.

Rated 5 out of 5 by from Beast!!!! This saw is a beast!!!!! This thing eats logs, with any chain. I have a 18" bar and it goes through a tree without a problem. I've used a green chain and a yellow,doesn't matter it will cut through it.

Rated 4 out of 5 by from Great saw I bought this saw to do storm damage clean up around Iowa. I've used it in the aftermath of 5 storms and the saw is great.I got the 25" bar and the saw has the power to cut full length.This saw is heavy but not against peer saws. This is one of two I use on such jobs. The other is a Stihl 211 I use for limbing. Much lighter and easier to handle for the small stuff.I would buy this saw again.
Date published: 2017-07-22
Rated 1 out of 5 by from Product is VERY Over Rated Hard to start from day one, saw doesn't want to run when first cranked unless it runs open throttle for a minute or two. If you idle it down sooner, every time I hit the trigger it bogs out dead. If the engine is cold many time it does not want to idle. Even when the engine is warm it can be difficult to crank. Boggs down on 12' mesquite, saw lacks power badly! No where close to satisfied with the performance or lack thereof, of this saw. I have never been this disappointed in any Stihl saw and I've been running them over 34 years.
Date published: 2017-05-22
Rated 5 out of 5 by from Easy start, powerfull, good controls and easy refill. Great saw. Easy starts (use Stihl fuel), adjustments are straightforward and easy to do in the field. Primary use is cut logs down to size, and resaw. All good.

Rated 5 out of 5 by from MS311 gets the job done The Stihl MS311 chain saw is a real pleasure to use and it has many excellent safety features. I also bought the Stihl safety chaps, and safety helmet with the face shield and hearing protection. All are quality products.
