    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.
* 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 4 out of 5 by Great saw, would buy again It pulls a little harder than I thought it would, that's the only reason for not getting 5 stars. I like the saw and would buy it again.Now I just wish it would stay sharp longer. October 21, 2016
Rated 5 out of 5 by Love my new saw This saw is awesome, the power behind it is like no other saw I have had before. When cutting it's like cutting butter. I would recommend this saw to anyone October 21, 2016
Rated 1 out of 5 by Not worth a plugged nickel Purchased new from robertsdale stihl dealer, a lot of internal parts missing, used less than a week and have it in another stihl dealers shop, informed that it is either rebuild or parts have been taken off to put on other chainsaws, beware when purchasing the last one the dealer has ms271 has been good but this one Will not cut a two inch saplings.

Rated 5 out of 5 by Owned a farm boss for 10 years I've had a farm boss for ten years now. It was my first chainsaw. Family has a 560 acre farm and we heat 2 houses with wood furnaces in each one. Every spring I cut approx 20 cords of firewood. The saw is what it should be. Quality made and there when you need it! Been in the shop once. One new sprocket & 2 new bars in ten years. Will even give my fathers 460 with 20" bar a run for its money just not as powerful. Went with the 18" bar and cut limbs to 24" logs. It's been dropped in the creek, pinched in a falling tree, dropped off the back of the side by side at 25 mph and works like new. Stihl should keep making quality products! Buy it and be done!

Rated 5 out of 5 by All the power I needed Purchased after having an older commercialGrade saw with a larger motor. It performsGreat, Starts great, very fuel efficient, andI have had no need for more power yet ,and seems just as durable, "Love it"! October 18, 2016
Rated 4 out of 5 by Good Power, but won't idle I've only used for one day. I used the Stihl fuel and bar oil. My only other Stihl is the MS171.From the first cut it was evident that the MS271 is built for power. It cut with ease through deadfall that was very hard and thick. While it wasn't fuel efficient on the first day, I assume it is like my MS171 and that it will improve with use. My issue with the MS271 is that it won't idle. Once off the trigger, what feels like a brake slowly engages to stop the chain, but then it pulls the motor all the way down to a stall. it is so frustrating to constantly need to pull the trigger and engage the chain between cuts. It reminds me of driving an old Mopar with a carburetor issue and having to shift into neutral an rev the engine at every stop. I'm going to have my dealer look at it, but that will put me down and out for a week.I will follow up with what I learn. October 17, 2016
Rated 5 out of 5 by Great Mid-Size Saw I chose the MS271 over the MS251 based on power. Both are great saws but I have a little more confidence in the 20" bar on the MS271 and it not bogging down. I've cut up one tree already and it was smooth, efficient and powerful. I have confidence in the investment I made. This saw will be with me for many years at the cabin and at home! October 12, 2016
Rated 5 out of 5 by Farm Boss the Best I've owned different brands of chainsaws. Stihl is, by far the best in the business. When I'm out and about during my work day I'm really happy to see all the pros out there using Stihl equipment. Looks like I made the right choice. October 11, 2016
