And with an advanced pre-separation air filtration system, your air filter can last up to five times longer. Another great feature is an advanced anti-vibration system to reduce user fatigue. STIHL engineering is to thank for this high-powered, high-tech, low-maintenance chainsaw. It is truly a force to be reckoned with.

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 4.4 out of 5 by 360.
Rated 5 out of 5 by from Quality Saw for the money I have owed other Stihl saws, so when my 18 inch bar saw conked out. Getting another Stihl was what I wanted. More power, lighter unit, and people who back up their product with parts support and service. Saw made short work of 80 foot pine!

Rated 5 out of 5 by from Starts easy Great saw starts good and has plenty of power to cut through big logs. Not to heavy and easy to handle.

Rated 5 out of 5 by from Better cutting After using other saw brands I find the Stihl out performs with the power as well as torque. Very happy with my purchase.

Rated 3 out of 5 by from Good for home owner but doesn't do strady work If you are cutting occasionally this a good saw. However, if you are cutting a lot of cord wood this saw will burn out! I thought I was getting a more durable saw. Oh well... I am disappointed as I have an older stihl and it is still running great.. not sure what they changed on this one but it isn't good.

Rated 5 out of 5 by from Firewood Workhorse I bought this saw to upgrade from a 170 for firewood cutting. I was split between this and the 271, but I ended up with this because of more power and the same weight. This can take on almost everything I can throw at it. I have both 20 and 18 inch bars for it. Starts up right away, has great anti-vibration features, and is easy to service. Keep a sharp chain, use the right fuel, and you’ll have a great saw.Not sure what more you could want in a firewood saw for the price.

Rated 5 out of 5 by from Love the saw I have had my ms291 for 4 years and have had no problems with it but on the down side I would like to be able to adjust the oiler my self I am running the 18" bar it came with and don't think it gets enough oil for the bar after cutting some big 16+" logs I need to let it cool off

Rated 2 out of 5 by from if it aint broke dont fix it I've always bought stihl, never considered a different brand until now. I purchased a MS 291 about a year ago. used last fall maybe 6 hours. took it back to dealer for him to check it. I was told that i didn't adjust the chain properly. I dont care what they say, the auto oiler does not work properly. I didn't know there was a problem with the old style. Why did they change systems? I only bought a new one to replace a saw that I've had 10 to 12 years and was just wore out. Dont get me wrong i love stihl but im pretty sure i know how to adjust the chain tension . So maybe something should be done to correct this. Or at least make it mandatory for salesman to inform you of these changes.

Standard Features

  • 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.

    More information

  • 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.
  • 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.
