    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…

MS 291 is rated 4.6 out of 5 by 186.
Rated 5 out of 5 by from Stihl MS291 Always grown up around my father and grandfather using stihl power equipment so when it came time for me to buy a chainsaw for my own home I went with the best I knew. I've used my ms291 for one season of firewood cutting. Dropped 3 oaks, and a hickory with it so far. I have zero complaints with the 291. It's a very powerful saw yet still light enough that I can stand to use it for long periods of time. It's well balanced and the anti vibration system is second to none. Overall it's a great product and I look forward to using it for many seasons to come.

Rated 5 out of 5 by from The best of the best There are certain things in life you should never skimp on, chainsaws are one of them. When you need it, you need it to perform well every time. Stihl is the bar that all other saws are measured by, don't settle for second best. This saw is exactly what I was looking for and I am happy with my purchase.

Rated 5 out of 5 by from This product is another of excellence from STIHL Purchased this chainsaw to replace a 18 year old STIHL 026 (which still runs like a champ). I was not disappointed. Eats thru all trees including Black Elm and sweet-gum. I own 4 lots and 2 of which are densely covered with trees and brush which is why i need a reliable moderate duty chainsaw. This product will last a lifetime.

Rated 4 out of 5 by from good product bad chain I very much like the power and weight combo and starting. But the chain is junk stretches when first out of box to max with in half a chord. Should do another swap kit like the 290 for a 3/8 chain.

Rated 5 out of 5 by from The only saw you'll ever need! I purchased the MS291 about 4 months ago. I took down about 10 hardwoods for a friend the morning a bought it. Wow, did I have a smile on my face! Could not get over how fast the cut rate was the the yellow chain. On Jan. 22, tornadoes devastated parts of our city. The following Sat. I went out with a clean up crew and ran 7 tanks of gas through it! I was worn out but the MS291 never got tired. I've cut a lot of trees over the last 15 plus years with a Different brand saw, but after using my first Stihl saw I will never use anything else!

Rated 5 out of 5 by from This is our go to saw This is our second MS-291.The original is 5 years old and has been our go to saw.We needed another saw and the choice was obvious. One stays at the farm and another in the garage. Living in the woods having a dependable saw is not a luxury it is a necessity. We trust our Stihl whether it`s saving us from a blown down tree ,a rotten log or to cut a monster oak off of our mother in laws roof. Firewood cutting is just another task this saw excels at.

Rated 5 out of 5 by from Not cheap but excellent saw Saw runs well with excellent power. I had to look around to find dealer to correctly sharpen chains but super chipper chain ( yellow spot ) sharpened correctly cuts terrific. I had to learn how to start the saw left handed to compensate for a shoulder problem. The saw starts ok but compression is high and requires a strong arm and good shoulder. Stay away from ethanol gas if you can, gas lines are a problem if you don't.

Rated 5 out of 5 by from Excellent Product Some of the trees I have cut was 30 inches in diameter and this saw cut thru the tree like it was a toothpick. No loss of power when cutting. The best chainsaw I have ever used.
