    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.
* 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.

Rated 5 out of 5 by from Great saw Saw starts easily and runs smooth. Great power. cut through 20 inch oak log 3 times faster than my previous Stihl saw. It does have more of a tendency to kick back but the torque and speed of cut is fantastic. Love the saw

Rated 1 out of 5 by from Will not idle, very disappointing I bought this saw less than a month ago. I was tired of cheap saws that were hard to start and wouldn't idle. Turns out this expensive "commercial" saw isn't any better than a cheap walmart saw. I've put about 7 tanks of gas through it, and am not happy with it at all. It takes a minimum of 4 pulls to start, sometimes as many as 10. Cold or hot, pushing the deco valve or not, same result. The worst part is it will not idle. Set it down, and after a few seconds it revs slightly, then dies. Just like a cheap poulan. I'm using stihl oil, and fresh gas varying up to 101 av gas.

Rated 5 out of 5 by from Another great product from Stihl I’ve owned this saw for three years and it hasn’t let me down yet. The antivibe, air filtration and power delivery is superior to my old MS290. Id high recommend this chainsaw.

Rated 5 out of 5 by from Lightweight and runs all day long I purchased this saw To compliment my MS192TC . I work them together out in our sustainable pine forest. Windfall,dead fall, invasive control, thinning,slash cleanup you name it this saw is a rock star of chainsaws. Lightweight and easy start are great feature when you work the saw hours at a time. I hire loggers to harvest but with my Stihl tag team cutting trees is a breeze,oak included. I also have a MS250 for light duty but I tell ya that saw has gonads too. All in all my saws are incredible to work with over long periods, they wont quit. Fuel consumption amazes me too. For a 50cc the MS261 CM is a powerful ,economical and reliable. I am a stihl guy from way back in the 1970's. I never imagined Stihl would make the incredible chainsaws they are making today back then. Once a stihl was left in the dump truck with fill soils . The driver dumped his load and the saw was buried for over 6 months. We were dozing the fill and the chainsaw popped out of the dirt. After cleaning , ,oil,refueling,new bar and chain it started right up. Was back on the job next day. Stihl rocks!

Rated 5 out of 5 by from Great all around saw, fantastic features and quality As a Stihl mechanic at a dealership, I knew when I bought a new saw it had to be a professional grade saw. I want a saw thats going to last a VERY long time even though I don't cut wood like a professional does. Just a good all around firewood saw, chore saw, storm cleanup saw, etc. After a year of research I enthusiastically bought the ms261cm. And boy I don't regret it one bit! It keeps up with the "big boys" just fine. Its power for its size is VERY impressive. It just won't quit! Starts easily and runs great! I'm impressed every time I use it. And being a Stihl mechanic, I understand the M-Tronic system better than your average joe. I've worked on saws (not mine) that the customer complained about its running characteristics. Easy! Reset the system, let it retune itself, and more often than not it's good to go! Customers need to be aware too that when refueling BE SURE YOUR FUEL CAN IS CLEAN, NOZZLE IS CLEAN, AND AROUND YOUR FUEL CAP IS CLEAN. The solenoids have plastic internals and the grit that can get through the filter can over time wear out the solenoid. The M-Tronic system itself is FANTASTIC but I, as well as Stihl, knows that when something does go wrong, 99% of the time the solenoids are bad due to grit. However, thats hardly Stihls fault: the customer needs to keep dirt out of their fuel! We have been reassured they are working on a solenoid with metal internals that won't have some of the issues the current ones do. But don't let that keep you from buying one! Being a pro saw parts will be available for a LONG time and will be better quality than your homeowner/farm and ranch saws.
