MS 261 C-MQ

MS 261 C-MQ
The same great MS 261, but with advanced STIHL M-Tronic™ and STIHL Quickstop® Plus technologies.

Product Description

The MS 261 C-MQ has all the same great features as the MS 261 – low exhaust emissions, high fuel efficiency and robust performance, but also features the advanced STIHL M-Tronic™ engine management system and STIHL Quickstop® Plus chain braking system. With STIHL M-Tronic™, an onboard microprocessor digitally monitors and automatically compensates for changes in your work conditions including elevation, temperature, fuel quality, varying octane levels and dirty air filters. The saw also features STIHL Quickstop® Plus, an additional chain braking feature designed to stop the chain in less than one second when you completely release the rear handle.

Model Features

  • STIHL M-Tronic™

  • STIHL Quickstop® Plus (Q) - an additional chain braking feature
    STIHL offers an additional, manually-activated chain brake on some models. This system is designed to engage when the operator’s right hand completely releases the rear handle, stopping the chain within one second. Available on some models.

  • 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.

  • 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…

MS 261 C-MQ is rated 4.5 out of 5 by 16.
Rated 5 out of 5 by from Nice light weight commercial saw Using this saw to manage 87 acres. New to chainsaws but this saw is easy to start operate and maintain. I just got to get familar with the dos and donts when cutting. Pinch my bar before I got the any of the paint worn. Rooky mistakes.

Rated 5 out of 5 by from Best safety features for firefighters My department bought this saw for its power size and weight, but I recommended that we get the C-MQ for its hand guard mounted brake. Before this saw I had some worries about lesser expirenced firefighters getting hurt when clearing trees from roadways and during brush fires. Now I worry less about the saw and more about the operators. Time for more training.

Rated 1 out of 5 by from and another m-tronic with a hot start issue... Was the perfect saw until the m-tronic hot start issue appeared. Google m-tronic hot start and see what I'm talking about. Other than that critical flaw, it's an awesome saw. I run a 20" bar and a rapid super chain. Cuts like crazy, but forget it restarting when it's hot.

Rated 5 out of 5 by from Great saw, that is lightweight, has plenty of power, and starts reliably. Took the saw to Northern Michigan and it preformed wonderfully. Its starts easily and has plenty of power. Used it on Ash, Oak, and forty foot pines trees. It is light weight even with the 20 inch bar I had installed. Used it at home yesterday and it started with one pull. I wish I had this saw twenty years ago it would have saved much frustration. Great saw.

Rated 5 out of 5 by from I'm amazed every time I use my MS261C I really don't leave reviews very often for anything but I really feel compelled to leave a review for my MS261C chainsaw. I grew up on a farm with lots of woods and we always used Stihl saws to cut wood for our wood stove. I moved back to Iowa and now live close to that farm where my parents, now retired, still live. My Dad bought me the MS261C as a birthday present as we have a large woodstove in our new house and plenty of timber. I cut up a lot of wood as the house is big and the stove is the largest one I could find. This saw is just amazing. I used it in the hottest days of Iowa summers and on very cold winter days as well. The thing starts every time and it just is so versatile - perfect if you only really have one chainsaw. It cuts small stuff and large stuff, no problem. I cut oak, cherry, hickory, mulberry, walnut, elm... it just doesn't matter, it happily chews through it all. I just love the balance of power and weight - it seems lighter than it should considering the power. Anyway, I know I sound like a Stihl salesman maybe but it seems so typical to be let down by machines and appliances in this era of cheaply made stuff - seems so rare to buy something so well built that consistently works so well. It makes me so happy, knowing there are still products made that are clearly quality made and by a company that must still be passionate about what they make. I had to leave a review. Thanks.

Rated 3 out of 5 by from Needs another 1 HP This is not a bad saw, just not good enough to get the job done. You can cut small stuff all day with this saw, but when it comes to cutting a round off a 16 inch tree this saw struggles and boggs out. If it had just 15-20% more power it would be a winner. Conclusion, spend a little more and get something with about five horsepower.

Rated 5 out of 5 by from Great replacement for my old Wood Boss 028 My last Stihl lasted 25 years and it was a difficult task to pick out a new saw. I choose the 261 and I could not be more pleased. Starts right up with plenty of power. Good nimble saw that preforms as expected.
