Rated 5 out of 5 Top notch saw One of still's many great products. Can't ever go wrong when buying a stihl. September 19, 2014
Rated 5 out of 5 by New purchase great results Purchased the MS391 after my 38 magnum was stolen. Used it to cut up a maple tree that was 4ft at the base. I've been cutting with it for a week now and it never fails to start,has more than ample power and isn't too heavy to bring on fatigue. Cut up 4cords in the last week and cut blocks when the knots became too hard to split. Overall quite pleased with the replacement,nice to see stihl has quality products that last,and are ready to use when you need them. September 15, 2014

Rated 5 out of 5 by The MS 391 is the perfect saw for me. I purchased this saw new in August 2014. It replaced a tired saw that I have had since the early 90's. It will be used primarily for firewood. I cut mostly Ponderosa pine and Douglas fir. This saw is a beast. I run a full skip chain on the 25" bar. I can fill it up with fuel, drop a tree, and cut enough 15" long rounds to fill the 8' bed of my F-250...and still have about half a tank of fuel. It starts easy, cuts fast, and is a pleasure to run. I think this is the perfect saw for me. September 9, 2014
Rated 3 out of 5 by ms391 I got my new ms391 home from the dealer and went to the woods started good with no problems it seems to cut ok but I thought it wood be more powerful and not really impressed so got done for the day and went up to my shop to clean up and blow off saws and put away when I took off cover for air cleaner I was not happy real cheep air filter then I got curious and took off cover for chain and was very mad Very cheep clutch drum I'm sorry but for what you pay for a new saw and this is what you get so this one will be sold and have to watch with what I buy to replace it all in all some people may like it but I'm not impressed at all stihl you can do better and yes all I use is stihl September 7, 2014
Rated 5 out of 5 by Awesome power I've owned the saw for over a year now I to had a farm boss and upgraded to the 391. It took a little while to get use to the little extra weight but the power I gained made it well worth it September 7, 2014
Rated 5 out of 5 by More Saw Than I Will Ever (Hopefully) Need A simple project, a fallen tree blocking a narrow road on my hunting property caused me to shop for a chainsaw. The tree itself was not huge, maybe 20" in diameter, but my philosophy for equipment purchases is to "overbuy" for the immediate task - I do not want to be under-equipped for a future job, within reason.After being very pleased with a Stihl clearing saw I recently purchased, I returned to my local Stihl dealer to look at chainsaws. I had done some research prior to my visit, but the dealer was able to address any questions I had about handling characteristics and reliability, particularly starting the saws.I chose the MS-391 with a 20" bar because it was the most powerful engine of the non-professional saws and it could take a 25" bar should I need one in the future. The saw made short work of my target tree with a factory sharpened chain and a powerful engine. I recall thinking that the saw gave me an unfair advantage over the job at hand - and I liked it!I have had no issues starting the saw and learned a trick to avoid mistiming moving the choke to warm-start from cold-start and flooding the engine. The dealer told me to listen for a short run/rumble of the engine after pulling the start cord with the choke set to cold-start. The rumble would indicate that it was time to move the choke to warm-start. He said some people did not hear this signal and consequently flooded the their engines.This saw has a decompression valve on the engine. You press it in to release combustion chamber pressure, making starting easier. When the engine turns over, even for an instance as in the pre-start "rumble", it pops back out. Instead of listening for the rumble, which I might miss with hearing protection on, I simply press the decomp valve after each pull of the starting cord. If it does not pop in, meaning the saw has not turned over at all, I keep the choke on cold-start. If the valve does pop in, I know the rumble has occurred and I move the choke to warm-start. My saw always starts on the next pull. August 17, 2014
Rated 5 out of 5 by This is my first saw. A friend owns an ms211 and an ms291. He recommended a bigger saw. So I bought the ms391 for Storm clean up. I upgraded to the 25" bar. It has plenty of power and has been very reliable so far. I have no complaints with the saw other than it feels heavy at the end of the day, but I don't think that's the saws fault. August 14, 2014
