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.

    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 4.6 out of 5 by 172.
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 Runs well, powerful. I've only had it a few weeks but am quite happy with it. It is lighter than the 40 year old one it replaces. Starts and idles with lots of power. I have the 25 inch bar so it is pulling a bit more chain than some. Only problem is getting the chain pinched limbing and cutting up a few trees. Good to have an ax and wedges handy.

Rated 5 out of 5 by from Good product and dependabie. I like the way the saw handles good power also i really like the bigger tanks great idea. I have had saw Sthil chainsaws since 1973 and have cut a lot of wood with now problems with the saws great product. I like the light saws but I don't really like all the plastic so kind of a give and take. Sthil chainsaws are good saws to operate all day every day.

Rated 5 out of 5 by from Excellent Trade Value Traded in an MS310, my first Stihl, and got a great offer on a new MS311. It was hard to part with the 310 until the very first day I used the 311. The 310 was a long lasting great machine. The 311 was easily the best saw I have ever used. About the same weight, start or pull assistant makes starting so easy a child could do it. The quality of a Stihl will make you happy but remember that the day you decide to upgrade your old Stihl will give you trade in credit off a new saw that no other brand can match.

Rated 5 out of 5 by from Great all around saw Had to drop some trees to build an addition on my house. This saw has enough power to get the job done all day long. If you're cutting through tough trees like popular, I strongly recommend a carbide tip chain.Overall a great saw!

Rated 5 out of 5 by from Great Saw I bought an MS311 about 3 years ago, when I had to cut 8 large mature Oaks & Hickorys. I also have two other chain saws, name starts with P. You cannot run one of those Ps for 1/2 hour without stopping to work on it, and that's if you can get one of them running. The MS311 cuts great, and really shines when cutting up trees. The trees I dropped were all 24"+ diameter at the base, and I cut the trees up into stove lengths in 2 sessions of about 3 hours each. Two tanks of gas, and no chain sharpening. I use a chainsaw infrequently, and this saw has started easily after months of inactivity. Just use the Stihl 2 cycle oil, and no gas problems. Starts quickly, no matter if it's 60 degrees or 16 degrees. Some have complained a little about the weight, but I didn't notice it being heavy. I'm a large fellow, perhaps the reason.

Rated 4 out of 5 by from Only one draw back I had to have 2 120' red oak trees cut down due to them being too close to the house and making an old retaining wall collapse. The 14" chain saw I had finally went beyond the economical repair price, so i decided to get a new saw.After researching several brands and knowing that my wife and I are going to change our lives from city slickers to homesteaders, I decided to buy my last large chain saw. With that in mind I settled on the MS311.After 2 long weekends of cutting up these massive trees, the only problem I had was a bad initial chain (dull). I had purchased 2 additional chains at point of purchase due to I did not want to spend time having to sharpen chains between uses. The initial start up on saw was a piece of cake, 2nd pull. The initial cut was a different story. I started a cut on a 16" dia logs and made it less than 1/2 way through before I thought I saw smoke coming from the cut. I turned off the saw and the blade/chain was warmer than I expected. I did some basic troubleshooting and determined it was a dull chain. I replaced it thinking that if all the blades were this way, I was in trouble and there was going to be some LONG weekends ahead. Come to find out it was the initial blade. That replacement blade started cutting through those logs like a hot knife through butter. Even the larger 30" - 32" dia logs were no issue. I have used that 2nd blade both weekends with no sharpening in-between and it is still working fine. I will sharpen it before I use it again though.The one thing I did notice was about the time I was out of gas, I was also out of bar oil.It is a little heaver than I expected after continuous use. Overall I would buy this one again and I would recommend it to any of my friends as well.
