    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 4 out of 5 by from Dependable Saw Cut our way out of two hurricanes in 3 years. We have worked this saw like a dog falling hundreds of trees and never had an issue until recently. Most of our trees are 12'' to 30'' diameter pines, cypress and oaks. Recently the muffler became loose and fell off, regardless of how tight the torx head screws were fastened they vibrated loose every few minutes. Installed new T27 torx screws and applied red high heat lock tight. Have not used the saw since, hope the problem is solved.

Rated 1 out of 5 by from Run away from this. Absolutely a pile of garbage. Stay away from it. I have a 10 year old chainsaw that starts better. I thought you guys were supposed to have good chainsaws. If i am spending 10 minutes starting this pile your wrong. This was a brand new chainsaw. Plus its made of cheap plastic that twists. How can you have a handle that is so pathetic.

Rated 5 out of 5 by from Great Saw I had a MS 290 Farm Boss, but wanted/needed a second one. I origianlly had another brand 18 inch 42cc ( I believe the specs are correct) prior to the MS 290. I was pretty frustrated with myself after purchasing the MS 290. Why in the heck didn't I buy a Stihl to start with? After using it my hands would be numb pretty quick. It's fairly difficult to get it started. Yes it was less money and if you only use it a few times maybe its ok. I wasn't sure at first if I wanted all the features that come with the 291. I haven't used it too much recently, but here is what I like. The added chain stop on the handle is great. Knowing it stops in the event of you dropping it or stumbling is reassuring. You should still treat it as though its live and running regardless. The easy start was a little different for me after having a traditional unit. After a few startups I become acccustom to it and works great. I have a 20 inch bar on it, so its a little heavy. I probably could make due with a 18 inch or maybe a 16. Again I haven't really put it through its paces yet, but so far its worked like I expected it to. I would recommend it and would buy it again if needed.

Rated 3 out of 5 by from Dealership Lacking I went to buy my 5th Stihl chainsaw in a 30 year period. Todays buy at W.L. Forestry Supplies Ltd left a lot to be desired. They took the saw off a shelf and PDI it. While I was paying for the saw and picking up the files and extra oil for the warranty extension bit. So I asked about a box and blade cover and they a said that is extra now. I guess a wrench to adjust the chain and bar is extra too. Didn't get a manual either. Are we suppose to ask for every item or are some actually included.

Rated 4 out of 5 by from This product could use some upgrading This saw is hard to restart after it warms up . You would think that if it was fueled when it was purchased it would be ready to run with out needing to set carb. yourself . It is on the light side and don't wear you out as fast as other saws have .
