MS 291

MS 291
A high-performance, fuel-efficient chainsaw. Great for felling, firewood cutting and storm cleanup.

Product Description

Another high-tech STIHL chainsaw, the MS 291 is built around one of our new fuel-saving engines with longer run times and lower emissions. And with an advanced pre-separation air filtration system, your air filter can last up to five times longer. Another great feature is an advanced anti-vibration system to reduce user fatigue. STIHL engineering is to thank for this high-powered, high-tech, low-maintenance chainsaw. It is truly a force to be reckoned with.

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.

MS 291 is rated 4.5 out of 5 by 226.
Rated 1 out of 5 by from Horrible saw with equally horrible service!!! I bought this saw earlier this month. The salesman started it successfully before I left. A few days later when I tried to start it, it did start after about 6 pulls. After 2 cuts through an 8" log, I turned it off when a neighbor stopped by. It wouldn't restart after innumerable attempts. I took the shroud off and removed the spark plug which was not flooded. Subsequently, it still wouldn't start. It did start on a return trip to the dealer, but when I got it home, it still wouldn't start despite 2 days of trying, checking the spark plug again, etc. I returned it to the dealer on Sept 11th and waited a week for a call to pick it up. Finally, I called the dealer and was told it would be 3-4 weeks before it was ready. I then called customer service on the 18th, waited on hold and then gave up and chose the option for them to call back. No call ever came. So, I spent a lot of money for a chainsaw 3 weeks ago, got 2 cuts out of it and will have to wait 3-4 weeks more before I get this piece of junk back. This is not acceptable!!!!!!!

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.

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 .

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

Standard Features

  • 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.

    More information

  • 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.
  • 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.
  • Common Features for Chainsaws
    View the features common to many STIHL chainsaws.
  • 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.
