    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.

MS 291 is rated 4.5 out of 5 by 288.
Rated 1 out of 5 by from This product does not allow enough oil to the bar and chain! Because of its very poor oiling system, I am on the third bar and fourth chain. No way to adjust the oil flow. I was thinking,” you get what you pay for” , so I went with a Stihl and paid a lot more for it than the previous two chainsaws that I currently own. BIG MISTAKE!!! Buyers regret to its extreme!!!!

Rated 4 out of 5 by from MS 291 My 291 has performed well. I seems to have plenty of power to get the job done. My only disappointment so far is that the front bar tightening bolt stripped out. I was told by the dealer that it is threaded into the plastic part of the case. Therefore you must be careful when tightening or it will strip. The dealer fixed it by installing a larger stud in the housing. Apparently, this is common, because he had them in stock and fixed it in a few minutes. I'm not sure what the remedy will be should the larger stud strip.

Rated 4 out of 5 by from So far it has been a great saw. I recently bought this MS291 saw to replace an older 029 which I bought in 1996. So far I have been impressed with the power the saw seems to have, as well as the easy starting. I can only hope that this saw will last as long as my old one did. Time will tell. The only thing I have found that I would change is the size of the fuel tank. It seems to be smaller, therefore you are stopping sooner to refuel.

Rated 5 out of 5 by from This saw has good power and is easy to service I bought this MS 291 saw to replace my Stihl 028 farm boss that still runs after 37 years of service. Wanted a saw that was bigger to take care of my property and has come very handy during hurricane season.

Rated 5 out of 5 by from Great saw I have owned many mid size saws and this is one of the best. I even like it better then My 026 pro for firewood. The saw is a great firewood saw. Its weight to power ratio is great. It starts easy and runs a long time on a tank of fuel. I'm using a 18" bar with stihl 26RM3 74 link. Im not wild on the plastic handle but it does work. I would recommend this saw for anyone who has a wood lot and cuts firewood for themselves.

Rated 5 out of 5 by from Good value First stihl and was really surprised on how easy it is to use and maintain. Cuts through big oak like a hot knife though butter. Only down side is it needs sharpened more often than my old saw.

Rated 4 out of 5 by from Powerful, but hard to start. This is my third Stihl chain saw. It is very powerful, but difficult to start. The compression is very high, making it difficult to pull the starter cord. I have had to take it back to the dealer more than once to get him to start it. I have learned a process that works better, pulling the starter a few times without choke before applying the choke. Otherwise, it can flood.Also, when R.I.P. cutting logs, the shavings build up in the housing and block the oil flow to the chain. I have to apply grease directly to the chain to keep it from freezing up on me.

Rated 5 out of 5 by from Perfect saw for cutting firewood I chose this saw based on the reviews and for the price. I needed something that I could spend many many hours on cutting firewood and not break the bank . So far I have bucked up a many spruce, hemlock, and doug fir logs between 12-30” in diameter. At first I was greatly disappointed with the cutting speed until I ditched the worthless safety chain and went in to the local Stihl shop and bought a chisel bit chain. It was a night and day difference. Also it is very light on the fuel and you don’t have to fill up on bar oil with every fuel up like older saws. To anyone that someday buys this saw I recommend the 20” bar with a chisel bit chain. You won’t be sorry!!

Rated 5 out of 5 by from Powerful chainsaw. Great buy I don't normally write reviews so this is something good. This chainsaw is very powerful and well built. It cuts through hardwood trees very well. Starts up from dry start with about 5 pulls. This is to be expected from starting dry with no primer (just choke). Warms up quickly so you can get to work within 45 seconds. There is lots of compression so you have to stand on the handle to pull start it. After it warms up it is easier to start holding upright. Uses a lot of fuel but that is to be expected from a larger higher performance engine. And with that it is very loud. You should wear hearing protection if you use it for a while. Fuel tank is a little on the small size so keep your container of fuel handy. I like this though because I always run my equipment dry when finishing a job. Overall great chainsaw.

Rated 5 out of 5 by from One heck of a saw Bought this saw Feb 2017 and nearing the 100 tree mark. My dad had Stihl saws when I was a boy and what a privilege to observe the evolution of the brand. Fuel efficiency is high - just cut 60ft red oak into firewood 20 in caliper on 1 tank of gas. The handle operates independently of the bar, absorbing all the shock and easing user fatigue. Starts(cold start) on 3rd pull almost every time regardless of temp. I recommend Stihl synthetic fuel; the saw performs better. Considering the power of the saw, the unit is a reasonable weight. The air filter improvement has extended intervals between cleanings drastically. Bar is easy to take off and clean. Sitting here trying to think what I might improve and truthfully can't think of anything. It's a heck of a saw.

Rated 5 out of 5 by from Wonderful chainsaw I put on the RS23 chain and it cuts very fast. The saw starts easy so I do not care about it not having a decompression button etc. I put in some long hard hours in all kinds of weather, it was used hard and no complaints.

Rated 4 out of 5 by from Dependable Saw Cut our way out of two hurricanes in 3 years. We have worked this saw like a dog falling hundreds of trees and never had an issue until recently. Most of our trees are 12'' to 30'' diameter pines, cypress and oaks. Recently the muffler became loose and fell off, regardless of how tight the torx head screws were fastened they vibrated loose every few minutes. Installed new T27 torx screws and applied red high heat lock tight. Have not used the saw since, hope the problem is solved.

Rated 1 out of 5 by from Run away from this. Absolutely a pile of garbage. Stay away from it. I have a 10 year old chainsaw that starts better. I thought you guys were supposed to have good chainsaws. If i am spending 10 minutes starting this pile your wrong. This was a brand new chainsaw. Plus its made of cheap plastic that twists. How can you have a handle that is so pathetic.

Rated 5 out of 5 by from Great Saw I had a MS 290 Farm Boss, but wanted/needed a second one. I origianlly had another brand 18 inch 42cc ( I believe the specs are correct) prior to the MS 290. I was pretty frustrated with myself after purchasing the MS 290. Why in the heck didn't I buy a Stihl to start with? After using it my hands would be numb pretty quick. It's fairly difficult to get it started. Yes it was less money and if you only use it a few times maybe its ok. I wasn't sure at first if I wanted all the features that come with the 291. I haven't used it too much recently, but here is what I like. The added chain stop on the handle is great. Knowing it stops in the event of you dropping it or stumbling is reassuring. You should still treat it as though its live and running regardless. The easy start was a little different for me after having a traditional unit. After a few startups I become acccustom to it and works great. I have a 20 inch bar on it, so its a little heavy. I probably could make due with a 18 inch or maybe a 16. Again I haven't really put it through its paces yet, but so far its worked like I expected it to. I would recommend it and would buy it again if needed.

Rated 3 out of 5 by from Dealership Lacking I went to buy my 5th Stihl chainsaw in a 30 year period. Todays buy at W.L. Forestry Supplies Ltd left a lot to be desired. They took the saw off a shelf and PDI it. While I was paying for the saw and picking up the files and extra oil for the warranty extension bit. So I asked about a box and blade cover and they a said that is extra now. I guess a wrench to adjust the chain and bar is extra too. Didn't get a manual either. Are we suppose to ask for every item or are some actually included.

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 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.
