    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.

    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.

    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.

    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.

    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%.
  • Zoom
    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.
  • 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.
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…

Rated 5 out of 5 by from Best saw in every way I've had my MS 261 for over a month now and use the saw every day. It will always be my first choice to use. It seems eager to get to work. Starts with ease, won't bog down even when I'm cutting big maple, oak and ash. I was a little hesitant to lay down the cash for this saw because I've been using the other orange brand with decent results...but convinced myself I should buy the Stihl to do a real comparison. I will never own another saw brand but Stihl now, and going into the purchase I was nervous I'd feel the opposite. I was worried I'd buy it and find little or no difference. My advice to anyone looking for a saw now.....but the Stihl....it's worth every penny.

Rated 5 out of 5 by from Great saw This saw has a lot of power for the size and always starts up easy. The air filtration is excellent, best in class in my opinion and will definitely make your saw last longer. I run a 18" bar and it pulls like crazy through hardwoods, has a lot of torque. Built like a tank.

Rated 5 out of 5 by from Excellent power to weight ratio. I especially like the canister air filter. Out of all the Stihl saws I have owned and ran this is my favorite. This is my go-to saw for nearly everything. Great power to weight ratio and features like the canister air filter and decompression button make this a great saw that is easy to start and run. I put a 3/8" bar, chain and sprocket on my saw and it made a world of difference in performance. This is my favorite saw out of all the saws I have owned and ran. When you now how they are made you'll choose STIHL.

Rated 5 out of 5 by from Well worth the price. I bought this saw about a year ago and I've been working it hard since. It has MORE than enough power to run the 18" bar through anything I've come across, namely mesquite, oak, pine, and cedar. I turned up the oil as high as it would go because oil is cheap compared to a bar and it really only uses a half a tank for every full tank of gas. My father in law has a MS251 that he uses for the same thing I do and it just doesn't have the power to cut as fast and can sometimes bog down when the whole bar is cutting. He also prefers to run the oil on the preset and his bar gets signivantly hotter than mine. My only gripe is when traveling from 500' to 7500' the automatic fuel/air can take a long time to adjust causing the saw to bog or never warm up fully. After 15 minutes or so it's right back at it. Don't buy anything else to save a few bucks. This saw is worth every penny

Rated 5 out of 5 by from Worth the extra money I bought this saw for a combination of everything, firewood, trimming, hinge cutting, etc. It did not disappoint. It's starts like clockwork on the 5th pull. I've got close to 100 hours on this saw with no hiccups. Great, dependable saw. I'm glad I spent the extra money. I have since bought a 170 for my smaller work, but still regularly use my 261.

Rated 5 out of 5 by from Typical Stihl Typical Stihl ... Dealer was very helpful and knowledgeable on product. Saw is everything I need and nothing I don't. I don't even bother shopping other brands now and haven't for years.
Date published: 2017-04-20
Rated 5 out of 5 by from Great Saw, low weight. This saw is just a beauty to operate. For a 4 hp saw, it's not heavy like some makes. Easy starting, A pro model that will last me forever.
