    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.
  • Zoom
    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.
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 Great product This chainsaw is a great value for the money, very well balance and power. Have to get used to the easy start but is a great feature May 8, 2016
Rated 1 out of 5 by Poor oiling system Used the ms 291 5 minutes and burnt the bar and chain up cause lack of oil . Took it to dealer had it worked on used it 5 minutes again same thing . Pretty bad I have a new saw and can't use it . May 7, 2016
Rated 5 out of 5 by Great saw for firewood Bought the saw brand new from a local dealer. Loved the saw and its power. I upgraded the saw by adding a set of dual felling spikes and then a 20 Stihl bar and chisel chain. Fast and great power. Only down side I wish it had was a metal tank and handle assembly like the MS-261. March 31, 2016
Rated 5 out of 5 by best saw on the go Real good saw stihl stands by there saws love the 291 has better power then the 290 as that was my last saw and it was a real good saw cut alot off wood March 25, 2016
Rated 5 out of 5 by Great farm saw I bought this saw lightly used. The bar and chain was a little small for what I was cutting. So a trip to my dealer I bought a new 20 inch bar, and a 325 pitch RS chisel chain (yellow link). I cut, and noodled two cords of wood without having to touch the chain up after all that cutting. There was some hard stuff too Osage Orange, white oak, black locust, it was still throwing the chips. Was easy on fuel, and bar oil. This is a great saw I don't need or want a bigger saw this one has plenty of power and is very nimble when felling trees thank you Stihl for making a great product. March 21, 2016
Rated 5 out of 5 by Great value very dependable Great saw for all types of work. Very reliable and easy to maintain. March 20, 2016
Rated 5 out of 5 by The best It's by far the best saw for the cost. Power to spare have been using it for a year now to clear old wood and cut firewood about 12 cord a season March 10, 2016
Rated 5 out of 5 by clearing so balanced and responsive, my new/first Stihl saw impressed me at first pull. also experienced great sales service at my local point of sale. can't wait to cut some larger trees and hardwood but first cuts on skinny pines and junk mango trees are really smooth and manageable.
