    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.
* The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
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.

MS 261 C-M is rated 4.7 out of 5 by 191.
Rated 5 out of 5 by from Does A Good Job Light, seems to have enough power and handles real good

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.

Rated 5 out of 5 by from MS261 C-M Love it!......picked it up yesterday, cut down a 18” tree like it was nothing. It started on 1st pull EVERY TIME I shut it off & restarted 10 minutes later so I don’t quite agree with reviews of this being an issue.Yes, it may be to soon to make this statement however, it’s a great saw for a Homeowner who wants Professional equipment.

Rated 5 out of 5 by from Great throttle response Perfect 50cc all purpose saw!!!!! Have used for everything in the yard and woods so far. Very happy with this saw, as I have been with all stihl products.
Date published: 2018-04-24
Rated 5 out of 5 by from Great Saw I recently traded my MS 391 in and got the MS 261 CM. The 391 was a great saw but heavy for the type of cutting I have been doing. The 261 has plenty of power to push the 20 inch bar all day without issues. The saw starts easy, runs all day and cleans up fast and lightweight. Couldn't be happier with the purchase. Thanks
