    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 5 out of 5 by from Smooth, powerful and easy to start Mine has the 18" bar. It has more than enough power to make short work of everything ive used it on. My only issue now is finding more work to use it on. Highly recommened.

Rated 5 out of 5 by from Easy to start and easy to continue starting after stopping I bought this Farm Boss in Avalon Ace hardware in Orlando, FL. The instruction to start/operate at Ace was excellent and the product is fantastic, reliable quality. It has power and very easy to start again after putting it down after several minutes. Delighted with this new machine.

Rated 5 out of 5 by from Would buy again The only issues I have had were on the first tank of gas it took several pulls to start. On about the 8th tank of gas, the saw is well broken in, and starts like a champ easily every time. I have not owned a chain saw in almost 30 years of living in the city, but when I bought my ranch, I did research and settled on the Stihl 271 with a 20 inch bar. I am very happy for the purchase, and I know that this saw is going to last. I mainly cut central Texas yaupon and post oak, and while I may not be pushing the saw too much, I have had to cut a couple larger oaks. I regularly use the saw in very hot and dry conditions and have had no spark issues. The weight is fine for the size of the saw, and really after a while it's a reasonable weight for the size of the saw

Rated 5 out of 5 by from Perfect amount of torque for a light saw that can handle a 20" bar with no issue at all Awesome saw that not only starts on the first pull but can cut threw wood like a hot knife threw butter
Date published: 2017-11-10
Rated 5 out of 5 by from fantastic product Great power and balance, easy to use. Love my Farm Boss.
Date published: 2017-11-09
Rated 3 out of 5 by from Problem with bar sprocket after several uses The saw is lightweight, starts and runs well and vibration is minimal. The only complaint is that the bar end sprocket failed within one month of use (maybe cut two cords with it)
Date published: 2017-11-08
Rated 5 out of 5 by from Just what i expected out of a Stihl product Great chainsaw, runs great, lots of power would recommend to anyone that wants a saw that works!!!
