    More information

  • STIHL Quickstop®
    STIHL chainsaws are equipped with a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a STIHL Quickstop® chain brake. The STIHL Quickstop® chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force. In some working positions, the STIHL Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.

  • 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.
  • STIHL ElastoStart™
    The ElastoStart™ starter handle is an exclusive feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
  • 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.
  • IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
  • Ematic™ Lubrication System
    The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.
  • 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.
  • Master Control Lever™
    The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
  • Adjustable Automatic Oiler
    The Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions.

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…

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.

Reviews

MS 261 is rated 4.8 out of 5 by 80.
Rated 5 out of 5 by from Easy to operate, very capable Like the no-tools bar tension adjustment feature and big gas/oil plugs that cannot be dropped. Not so impressed with starting system. Like the tried and true pull cord system better

Rated 5 out of 5 by from This saw is the Boss This saw made mincemeat out out oak, pine, cherry, camphor.there was no stopping this boy once I put the chain to the bark.

Rated 5 out of 5 by from This saw rips! The quality of the materials used and the build quality of this saw are top notch. Once you're standing behind this saw, you know beyond a shadow of a doubt you made the right decision. This saw absolutely ripped through everything I've threw at it during hurricane Irma clean up. About the thing I wish I had differently was to buy one sooner.

Rated 5 out of 5 by from The Perfect Saw for 95% of Jobs This is the saw my guys and I always reach for when heading out. We run a short 16' bar on it but as a result it just rips though material and the nice part about it is that it is so light weight that you can run it all day and not feel it unlike our larger 4xx and 6xx saws but yet it keeps up with the exception of in large hard wood but once again it weights 10 LBS. You can't beat it. Worth every dime.

Rated 5 out of 5 by from Excellent Saw Purchased the MS 261 to replace an older MS 270 Farm Boss. The MS 261 performs very well and the anti-vibration system is a noticeable improvement. The power-head is physically a little bit smaller than the MS 270, although both saws feel pretty close to the same weight. Regarding power, the MS 261 handles an 18 inch bar very well. Running through Maple is not a problem at all. Is it much more powerful than the MS 270? In my case yes, but my MS 270 has had lots of run time over the last several years. The MS 261 is a pleasure to handle, cuts well, and won't wear you out. It feels very well built and runs pretty smooth. I would recommend it to anyone looking to buy a nice saw for the long haul.
