    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 4.8 out of 5 by 136.
Rated 5 out of 5 by from Best saw ever I just purchased this saw for a major project and it performed better than expected, the power was unreal and the weight was comfortable I used it all day on wet wood and it never complained, I must say it was worth the extra money! wow I am sold on this saw, way to go Stihl, I love my saw.

Rated 5 out of 5 by from I love this saw This is my kind of saw. It has lots of power and cuts like a saw should. I use this saw from 7000 feet to 10,000, at 10,000 feet it starts on the 4th pull when it is cold and starts very easy on one pull when its warm. My old saw was hard to start cold and wouldn't start warm. It is a delight to use, it is light for its horse power and will last me for years to come. Thank you Stihl.

Rated 4 out of 5 by from Nice machine, but hard to cold start I used a neighbors old MS 034 pretty extensively, and was sold on Stihl quality, verses other saws tried. I read and watched a lot of reviews, and settled on the MS 261 C-M, and eventually got one. I like the design, build quality, and 'feel' of the machine very much. I like the pro-grade features. And I especially like the power:weight ratio of this machine. That was the main deciding factor for me in model selection.However, I have two 'cons' to share:(1) it is much harder to start than I had hoped - especially in a machine that is supposedly designed for easy starting (re: the M-tronics and decompression button). Takes about 12 pulls for cold start (1-2 at full choke, until decompression button first pops out; then about 10 more pulls, at half choke again using the decompression feature.) Usually stalls then too, after initial cold start. But will start more easily after that. (So much for M-tronics!) Note too, that you really need to use that decompression button on this model. Else the pull is almost impossible - very stiff and jerky. Warm starts are very good - one pull only (at run position works best on my machine, not on half choke as expected).(2) I am also a bit disappointed in the manual - both paper copy received, and on-line .pdf versions I have found. They are pretty good in most respects, but lack sufficient detail for things like carburetor tuning. There is even confusion about whether the manual received is really for the machine that I have. Which manuals, and which text and pics in the manuals, pertains to the MS 261 vs the MS 261 C-M vs the MS 261 C-MQ is unclear.I would probably still make the same choice again. But my new owner experience, getting acquainted with and comfortable with this machine, is more involved than expected. Am still hopeful that Stihl quality, reliability, and usability will prevail, once I get more familiar with this particular machine.

Rated 5 out of 5 by from Great firewood saw I needed a new saw that could handle large elevation changes. First time out I was up at 9200 ft and I had no issues. The Mtronic system worked great. I cut dead pine and the saw had no problem pulling an 18 inch bar. Light, powerful with the latest technology. Stihl has real winner with the 261 C-M.

Rated 5 out of 5 by from This is a great saw that is replacing my old 026 and I really like it's lightness and easy start. The guys at d &b supply help me find the right saw for getting firewood! This is easy to,start, light weight and had all the power I need for cutting firewood . I also like the fingers only to open the fuel and bar oil caps.

Rated 5 out of 5 by from awesome midsize saw. if you want one saw that will probably do everything you need it to this is your saw. I also have a MS460 and a 066.

Rated 5 out of 5 by from Favorite saw from stihl Our company uses nothing but Stihl saws, wanted a new mid range saw so decided to try this one, was not dissapointed, not to heavy or cumbersome, but also has the power to go through the big stuff, in our opinion best all around saw we've tried in Stihl, highly recommended

Rated 5 out of 5 by from I like it I bought mine with a 20" bar and even the dealer looked at me like I was crazy.With the 20" bar pine is no problem and it went end to end on the bar through oak better then I thought it would.I will be purchasing a 18" bar thou for the smaller stuff.I have had no problems so far but I am not using it every day like some do out there but I am happy I finally bought a saw I don't have to fight to start.I also love the easy access covers on it and chain tightening is so easy. There is no reason to be putting away a dirty saw after the day is over.
