    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.

    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.
  • Zoom
    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.
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.

Rated 4.8 out of 5 by 81reviewers.
Rated 5 out of 5 by Great saw Finally decided to go buy an MS 241.When I arrived at my dealer I also looked at MS 261 Big mistake because I left with two news saws.Took saws out today and man do I love both My 290 Farm Boss will spend a lot of time in toolbox of truck.I am now the owner of three pro grade Stihl saws 241 261 and 372 . The pro grade saws are awesome Thanks Stihl and my dealer Phillips Equipment Lynchburg VA October 16, 2016
Rated 5 out of 5 by Powerful and versatile Very powerful saw for the size and weight. While it comes with an 18" bar, it easily powers a 20" bar when you need a little more length. The saw complements my 193 perfectly. While I would love to have another larger saw, I have not run into a tree or situation that I couldn't overcome. Great saw and I highly recommend it. October 8, 2016
Rated 5 out of 5 by best saw for the money I have several Stihl saws this one is by far my favorite. I do not have anything bad to saw about it. October 7, 2016
Rated 5 out of 5 by Can keep up to the big boys I purchased this saw last winter put a full chisel chain on it this saw can almost keep up to my 440 and 460 awesome saw I had to order another one, light weight, starts easy August 30, 2016
Rated 5 out of 5 by Excellent power to weight ratio After reviewing all the saw features, I decided on the MS261CM. It came with the 18" bar and the green label "Anti-Kickback" chain. So, for the occasional user looking for professional quality, safety and great power to weight ratio, This is throne! August 27, 2016
Rated 5 out of 5 by Does it all! Great power to weight ratio, balanced, torque, build quality and M-tronic! This saw does everything very well! It has a great power to weight ratio, it is very well balanced, has great torque and the build quality is exceptional! I had no problem paying more for this than either a homeowner or ranch saw. It also starts, idles and restarts great! The M-tronic is a great feature! I now would require the M-tronic on any other saw I purchase. I'm extremely please with it! Simply put it is exceptional. I'm not sure what I would recommend to improve upon it? August 26, 2016
Rated 5 out of 5 by Worthy replacement for .028 Wood Boss After 25 years my Stihl .028 suffered a score on the piston & rings, probably from a piece of carbon breaking loose. I looked to Stihl for a replacement of course and first tried an MS250. I found it was not nearly the saw I was used to using and did not meet my expectations. I then moved up to the MS261. While considerably more expensive it also compares favorably to my old saw, including bar/chain compatibility. It's a great saw with a number of improvements over the .028. I'm very satisfied and if it lasts me another 25 years I'll be 100 years old and will probably have quit sawing wood. August 24, 2016
Rated 5 out of 5 by First experience with my 2016 MS 261 cm I took my new MS 261 saw out to cut some very hard dead gum trees and it performed wonderfully. After putting gas and oil into the saw and setting the controls as directed, the saw came to life and idled right off. After the initial start up, the saw started first pull. The new version is a little lighter and has a little more hp. The weight difference will make a big difference after a few hours of sawing but this saw has lots of hp so I don't think I will notice the hp improvement.. I have a 20 in bar and need to up the oil going to the bar. I now look forward to working with it. August 6, 2016
