    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.

    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 291 is rated 4.5 out of 5 by 225.
Rated 5 out of 5 by from Powerful, Reliable & Easy to Run I have run this saw for 5-7 hours nearly non-stop on a few dozen days since purchase. After some irritating issues starting cold on the first few tanks of fuel during break-in it now fires easily and has since run flawlessly. Unlike other saws I have owned/used it does not throw nearly as much bar oil. While it does run a bit hot and I make a point of clearing the oil inlet on the bar it seems to be by design. I went with an 18" bar to keep the torque up and think it is a good fit for the motor. Top marks to the MS291 for someone who wants to run a saw for large firewood cuts and heavy clearing with virtually zero maintenance.

Rated 1 out of 5 by from Mediocre saw. Service even worse. Bought a Stihl MS291 disregarding several recommendations to go with a competitor. My dad has had his Stihl for years, so I figured 'why not?'.Unfortunately, this saw didn't make the cut - nor did the customer service.Experience: 10 years firefighting - structural & wildland; land manager 1000+ acres; heat primarily with wood - Central Boiler 5036I have had continual issues with this saw, namely with tensioning issues on the chain and bar. The bar nuts frequently fall off, yet if overtightened, do not allow movement of the chain. The last straw was after I took the saw apart, cleaned everything up and put it back together, put the faceplate back on, tightened the nuts, fired it up...walked 100 yards, and one of the nuts was gone. I've had other experienced operators adjust the tension and run the saw, and they experience the same issues - all are very surprised as they've never seen these issues from any saw. I have also had issues with stalling lately, after the 1st use after an overhaul from the dealer.It's been into one dealer several times - one time for several weeks - whom can't answer why I'm having the issues, and I spoke to another dealer that said he had never heard of such a thing.I took the issues directly to Stihl, as compared to going back to a dealer. I don't have time to deal with my saw being down all the time - It was time for Stihl to stand behind their product. Stihl's response "take it back to the dealer." I told them no. No response.Bought a new saw... from a competitor.

Rated 5 out of 5 by from Great Saw!! A must have if you are going to do anything with a chainsaw other than trim limbs. Starts easy and power to spare.
Date published: 2017-09-05
Rated 3 out of 5 by from I got a lemon First off the bar wasn't getting oiled, it kept getting hot when free spun without cutting. Then I noticed that the oil pump is just leaking out the bottom. Took it back to the dealer and they told me to contact the company. I got told it was normal but I literally need to keep a bottle of oil close just to pour directly on the bar to keep from over heating. I love stihl products and it won't keep me from buying more I'm just dissatisfied with this product.

Rated 4 out of 5 by from This product has good features This saw works very well and has lots of power but it's extremely heavy !! If you use this saw for a couple hours you will get a work out so really consider that before purchasing this saw .
Date published: 2017-07-27
Rated 5 out of 5 by from A great combination of function and serviceability. I paid the extra $100 for the MS291's additional .5HP (vs the same size and weight MS271), and am glad I did. My first chore was felling a 2 1/2ft dia. silver maple, so very hard, dense wood. Lots of cleanup cutting too, just to get pieces of the - again super heavy - tree down to moveable size. The saw's powerful, accurate cutting made for dropping the tree within inches of where I wanted it. So much (hard) cutting made for multiple chain adjustments, and one quick sharpening job. This is where the saw's serviceability came in. Super fast and easy with Stihl's chain tensioning system. This was a big, tough job for an out-of-the-box saw, which is not yet producing peak power (not yet broken in). And being one to really take care of my stuff, I again enjoyed Stihl's fantastic design when cleaning out the air filter. An (again) easy twist-off design. A little compressed air and the filter and engine were as clean as new. This saw's power and 20 inch bar make it a machine for experienced users. It's not something I'd recommend for the novice. You'll want all the safety gear (chaps, head and face protection, ...) I've done many years of forestry management for the Nature Conservancy and other organizations,and have been using chain saws for the better part of 47 years. The Stihl MS291 rates as the best I've ever owned, and one of the very best I've ever used. S. Cummings, Boulder, CO

Rated 4 out of 5 by from More reliable than my MS 170 and 171 no problems except occ hard to start if very hot. cuts fast, easy to use
Date published: 2017-07-16
Rated 2 out of 5 by from disappointed I've had chainsaws for over 30 years. Not on a large scale, typical homeowner use. Bought an outside boiler and knew the chainsaws I had wouldn't hold up to the extra use. guys kept telling me: quit buying cheap saws, get a real one...Time to step up to a Stihl!! the 291 one was recommended by dealer. Had no problems with it for the 2.5 years I've had it. except one time it stalled and didn't start again that day. but cut about 4 cords since then. UNTIL about a month ago. ran 2 tanks through that day. it stalled.. needed fuel. topped of fuel and chain oil. Never started again. No spark. I did some checking, figured it to be the coil. Took to dealer. he said same. Under warranty. New coil goes on. Still no spark. he continues to investigate..A few weeks later, they call and say the piston is scored. Ran straight gas!!! No way.!! I learned of the bad stuff ethanol does to 2 strokes. so when I bought this saw. I bought new can, marked off for 1 gal and 2 gal. and use the Stihl oil.. no way did I put in straight gas. .. and no one has ever borrowed it.. I use ethanol free gas and it was no more than 2 months old at the time I ran this.. Been in discussions with other dealers and friends on what may have happened so still investigating. I can't argue that looking at the piston, it looks like it was oil starved, so I have no dispute with the initial determination, just that I can't see how it's from my fuel mixture. I have sent this to Stihl directly and they sent comment to a dealer, so in process... I need a saw now so will buy another primary... so back to the research. Good thing I have my other saw I bought for smaller work.. and it's using the same fuel mix that the Stihl conked out on... (and my "cheap saws" still work well)So at this time, I can't really recommend the saw. Once I have resolution, I'll update.Still don't understand why I don't have spark, though...
