    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.

MS 261 C-M is rated 4.7 out of 5 by 195.
Rated 5 out of 5 by from Exceptional Power Tool So I’ll start the record off by saying that my experience with chainsaws is barely more than minimal, as at the time of purchase the biggest thing I ever had to cut was maybe 2”. I’d also never purchased a chainsaw. I needed a quality saw to maintain my new property which has over 3 acres of dense trees of all types and sizes. The woods have been severely neglected and many problem trees need removed as well as general cleanup.I wanted to learn what I was doing on a medium sized saw of high quality and that’s exactly what I got with this. I got this with an 18” bar and it will be doing a lot of work including felling of trees from 4-24”. The power is unreal given how light the saw is and the speed of the cutting was so fast it actually scared me into buying a full set of PPE. I would recommend this saw to anyone. I have had zero issues with the m-tronic it’s the way to go, I never have to worry about getting my carburetor adjusted or tuned and the saw just keeps getting better with each fuel tank.

Rated 5 out of 5 by from Great replacement for my 026 Pro During a remodel of my lake home, my trusty 026 Pro (purchased in 2000 w/18" bar setup) decided to go home with one of the workmen in 2012! Purchased the ms 261 C-M w/16" bar and broke the engine in on an 18in. dia. Pear tree. My initial impressions were 1) STRONG 50cc. engine, 2) Light weight and good balance w/ 16" bar 3) M-tronics auto adjust works as stated 4) 2-3 pulls to start cold, 1 pull start when Hot. 5) Good replacement for the 026 Pro.***Now, the real proof of value was when I helped a neighbor fell, limb and buck a 16" dia. Maple that was severely damaged during a storm. Neighbor had a Husky 545 and I used it to buck 1/2 the tree. The Husky didn't have the power to 'stay in the cut', bogged down often and was hard to start Hot. My 261 C-M was a TOTALLY different saw, with more than enough power, stayed in the cut easily with no bogging down and started on 1 pull when Hot. The Husky 545 was an ok saw but was frustrating to use... the 261 C-M was much more easy to use, more power, less vibration and MUCH less frustrating and less energy spent that entire afternoon helping the neighbor. I'm not at all sad my trusty old 026 Pro left me! Next up, ms201T c-m break-in!

Rated 1 out of 5 by from Worst saw i have ever owned. For some reason saw starts great initially, but after 5 to 10 minutes of run time if you shut it off good luck getting it started. Saw is just over a month old it has been garbage since day one.

Rated 5 out of 5 by from Nice Chainsaw Weight is a factor when cutting all day, I used to use a Farm Boss 029, (until the engine gave out) this saw was close to 30 years old.Looked into replacing my 029 with a new version of the Farm Boss, but after some research I found the MS 261 C-M, it is lighter and more powerful and a little over $100 more but, weight and power is everything when cutting wood all day. This is a great chainsaw, starts easy (1 or 2 pulls) and runs for hours on a tank of fuel.Best of all it uses the same chains and bar as my old Farm Boss 029. This was a big factor in my purchase, along with the weight and power of the saw.Also, you can extend your warranty by an extra year by purchasing oil to mix with your gas...you need it anyway, so why not have some extra oil on hand for another full year of warranty coverage on your saw. As For the cost--YOU GET WHAT YOU PAY FOR--go cheap and be disappointed.

Rated 5 out of 5 by from Does A Good Job Light, seems to have enough power and handles real good
Date published: 2018-05-18
Rated 5 out of 5 by from Smooth and powerful saw makes the job a pleasure. I absolutely love this saw. My toughest project was cutting 66 "pavers" from an oak trunk for about five hours straight, pausing only to sharpen the chain once. The saw worked flawlessly right up to the point at which it died. Evidently, although I used the recommended fuel to oil mix ratio, with non-ethanol gas, the Stihl brand bar lube, the piston seized and would not run beyond that point. I almost take it as a badge of honor that I killed a professional grade saw. It seems we hurt most the ones we love the most. Alas. I'll be buying my second MS 261 C-M very soon.

Rated 5 out of 5 by from Easy start, good power & balance Easy start, good power & balance. I bought this saw for home use after having a couple of "home use" saws that barely get the job done, and require more maintenance then they are worth. Spend the extra money and get a quality saw. This saw is a keeper.

Rated 5 out of 5 by from Great saw so far Yes I haven’t had this saw long but so far so good. This saw has great power for its size and weight. We run stihls at work and they have been great . Yes if you pull starter fast and very quickly they can and will flood. I have seen some other reviews that people are having problems starting there’s so far it’s been one to two pulls every time so far. This is my first m tronics saw of my own. We have a 661 m tronics at work for a few years and haven’t had a bit of problem with it. For a big saw it is a joy to cut with. Back to the ms261cm mine has the 20” bar with 26rm3 chain on it. For as light as this saw is the 18” probably balances the saw the best. If you put scabbard cover on it. The saw kinda leans forward a little. But no problem in hand it is light and compared to my Husqvarnas. I like that the m tronics carb sets itself up for maximum power in different temperatures and elevations. And it doesn’t seem to over rev at all. I am very pleased with this saw it seems to be of good quality. I probably didn’t need a pro series saw but I wanted something I hope lasts me a long time and is serviceable. I highly recommend this saw so far. Will do a follow up review after a while of good use to see how well the saw holds up over time.
