    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.

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.

Rated 5 out of 5 by from Outstanding chainsaw!!!! Bought this for our home that needed tons of trees trimmed and or cut down. It handled the job with a breeze. Since we bought this home I bought this one so it could keep up as long as we own this home. Bought everything Stihl so far as my wife is from the loghing part of Oregon and she told me they were the best. I agree!!!!!

Rated 5 out of 5 by from All around best This is the saw that will do it all. It is powerful but not too heavy. I use it for cutting large trees for firewood. It is the perfect size and is totally dependable - making short order of tough jobs! I owned a Farm Boss for 30 years and just got this newest model recently and it is all I ever hoped it would be. Still a straight forward basic saw but improved just right.

Rated 5 out of 5 by from Excellent saw I had a large tree take out my garage last week, and needed quick action to prevent further damage. I had already researched the MS271 Farm Boss, and was waiting for the right time to make the purchase. The tree sort of made it the right time, since my other saws ,which are not Stihls, are out at the farm. I picked the saw up within an hour, and was back cutting right away. Saw is a dream to wield, cuts well, and starts right up. Looking forward to attacking my overgrown timber stands at the farm when the snow clears a bit. Very pleased with this purchase.

Rated 5 out of 5 by from Excellent chainsaw Got the 20 inch version one morning from my nearest dealer who is fantastic. Bought on a whim to replace a very old red chainsaw that I was tired of messing with. Fired up immediately using leftover mix from my Stihl blower. Tore through a ten-inch-diameter 40 foot pine like it was made of cheddar cheese. Tensioned the chain and checked the bar oil. Then tore through 50+ feet of hardwood nearly two feet across until the chain got dull (my fault, I think I touched the dirt with it by mistake when making 2-foot sections to haul away.) Switched for the spare chain and no problems since. Already worn some white paint off the bar so I guess it's broken in. Awesome, awesome saw with plenty of power that I'm expecting to get great use out of for many years.

Rated 2 out of 5 by from Doesn't work Just purchased and worked fine for the first 20-minute test. The next day it started and quickly died and would not restart regardless of choke combination, letting it rest (flooded?), etc. This went on for the better part of an hour until the sun went down and I gave up.No wood cut, wasted my time. So now I have to drive back to the dealer and determine the issue or attempt to get a refund? Cheaper chain saws I've had in the past have been more reliable than this doorstop.

Rated 5 out of 5 by from Dependable Been running this saw for 3 yrs, never a problem. Follow the starting procedure and it fires up every time. Light enough for bucking, but still has enough power to handle felling, at least for the trees I cut. Keep a sharp chain and this will handle anything you throw at it. The only tricky thing I’ve run into is hot starts after refueling during a job. It’s seemed counter intuitive but I’ve had to go full choke to start back up even though the saw is warm. Very solid tool though, I’ve run it hot weather and zero degrees and it has not let me down. I would only run a Stihl from now on.

Rated 5 out of 5 by from Words cannot describe the full experience I have used other saws before and I have never used a saw that is so easy to use and so smooth. Cutting through wood like its butter is exactly what this saw does. I have the Farm Boss 20" bar and I have cut through all types of wood, pine, maple, ash, hickory, and the saw performs just as well no matter what type. Anti vibration makes it so much more enjoyable to cut wood, I was on the saw for 4+ hours only to stop to fuel and check my bar and chain oil and there was very little fatigue. I am only on my 5th tank of gas so I have not had much maintenance to perform but the cleaning after each use is very easy. The air flow feature with the winter and summer options are pretty neat. You are out in the cold and working so it never seems that bad but when your hands never get cold because of this feature, that just makes the saw and STIHL and even better product! I am not sure what else to say about the saw except for the reader to go get one and I promise you will not be dissatisfied with your choice! Get the Farm Boss MS 271 in a 20" bar and you will not use any other saw again (I am not associated any way with STIHL except for me saw, I am promoting your purchase on my own experience). This saw is the best saw out there and makes a long day of cutting wood less work and more fun!

Rated 5 out of 5 by from Couldn't ask for better I purchased the MS271 as my first chainsaw to use for cutting firewood and man am I pleased. I have used others chainsaws in the past and this one by far exceeds the power and comfort of the others I have used. Great quality, starts easily and is a powerhouse. Wouldn't trade it for any other saw.

Rated 5 out of 5 by from Good Power. Starts every time. Bought the MS271 last year and been cutting lots of wood had one issue but it got replaced and been going good ever since. I had used others my friends had but this one puts me to shame and they all went out and bought the same saw. I'm going to upgrade to a pro saw soon but will keep this one. If your looking for a good saw look no farther.

Rated 5 out of 5 by from Best saw for the dollar First chainsaw I ever bought and I am highly impressed with its performance. I’ve used other smaller STIHL chainsaws and liked them but I’ve never had one cut with the ease this one does. Very powerful, reliable, easy to start and can handle any size tree you want down as far as the bar will reach.

Rated 5 out of 5 by from Great Saw Very nice, sturdy, reliable and powerful. I borrowed a friend's different branded saw prior to purchasing this beauty. Other saw was hard to start, underpowered and a general pain to use. The Stihl is on another level. You will be happy with your purchase.

Rated 5 out of 5 by from Life Saver I live in the US Virgin islands, After being hit by TWO Cat 5 hurricanes only 2 weeks apart, we had our work CUT out for us. Spent about 30 days with this saw in my hand. She took any fallen tree like a dream. Helping get many people out of their houses, and cleared the road so our community could drive safely. Between a handful of 271's and 250's, the majority of the island of St John was cleared. These saws saved lives and I owe them my own. Big thanks to Stihl, and Kenny Chesney who sent the best saws to us after the storm.

Rated 5 out of 5 by from A Great Saw for Everyday Use I've had this saw for about a month now and have had no problems. Cuts through dry walnut better than any saw I've ever had. Starts right up, runs, and idles well. I've been using it to cut larger brush and fallen trees around my 10 acres and have had no issues with continuous use. Power to weight is perfect for my use.

Rated 5 out of 5 by from The cat's meow! I have owned several other chain saws, and friends of mine have consistantly told me "get a Stihl". My response has always been "I can't afford it". WELL, now that I own one, is have changed that. "I Can't afford not to own one!"East starting, easy to change the blade, easy to fill and maintain. HIGHLY RECOMMEND!

Rated 5 out of 5 by from Amazing chainsaw. Amazing chainsaw. I was in the market for a new chainsaw. I had so many problems with my old one, that I had enough with it. So I researched brands, as I did when buying my weedeater. I picked Stihl then for a reason, as I did this time too. However, I really wasn't sure which one to get. I had narrowed the choices down to the 250/251, 271, and 291. I really didn't need the power of the 291, nor the weight of it. The 250/251 were cheaper and weighed less, but they're only 5 cc larger than my old saw. So I picked the 271, and boy am I glad I did. It practically weighs the same as my old saw, but can cut stuff more than twice as fast. Love the fuel and chain oil caps, and the fact I don't have to use a scrench or the strength of 10 men to tighten or loosen them.
