MS 391
Rated 4.8 out of 5 by 124reviewers.
Rated 5 out of 5 by Great running mid-range saw. The saw starts easily, runs great, and has great anti-vibe mounts. Great saw for the price and power. I'm also impressed with the oiler. It seems to handle longer bars with ease. I'm happy with my investment. March 29, 2015
Rated 5 out of 5 by A Beast Right Out Of The Box I've been a Stihl user for quite a few years now. Bought an 025 back in 1998 when I was a city dweller to cut fire wood for the fireplace. Used that saw over the years, and still use it today. Runs great and is easy to maintain.Moved to the great North woods of Montana a while back and quickly found out that the old 025, while a great saw, just couldn't keep up with the wood demand of those cold Montana winters. Now I just use that saw for limbing and felling smaller tress around the property.Went to my local Stihl dealer to look for a new saw. I had done my homework and went straight to the MS391. Got it home and gassed her up. Now, I've read some reviews about hard starting and flooding with this saw and the only comment I have is...not true. I figured "heck, I'll just start this saw just like I start my old 025 saw, and let's see what happens." What happened was, it started right up and was purring like a kitten ready to thrash my now trembling wood pile.In all seriousness, if started correctly, this saw fires right up. On a cold start, as soon as the saw burps, switch the lever to the warm start position and it'll fire up on the next pull. My old 025 starts the same way my new fire breather does.As for performance, well, I was blowing through 30" rounds like a hot knife through butter. I have the 25" bar and the saw performed flawlessly. I wouldn't recommend this saw to the average Joe but, if you're cutting 4-7 cords a season like I do, then yes, absolutely, I would recommend this saw.I've seen comments about weight as well. I'm an older guy and well, I just don't see it as a heavy saw. A friend of mine has a Husky (poor guy) and I didn't see a noticeable difference between saws. For how fast the saw cuts, you're not really holding it all that long to begin with. March 26, 2015
Rated 5 out of 5 by STIHL FOR LIFE After going through several other saws that rhyme with...raftsman..I took the plunge, spent the extra money, and went to the Stihl dealer. I'm not one to buy new, expensive stuff. I prefer someone else do that, break it, then I buy it cheap and fix it. Problem is, Stihl maintains its value. So everyone selling one used wants retail price! I have not the first regret in this purchase. I pull the string a couple times, she cranks right up. I pull the trigger, whatever is in the way is...cut..quickly and with ease. I only cut hard wood. My last project was a red oak about 6 ft at the base. The 391 has yet to complain. It's happy place is all 20" of the bar buried in oak shooting fat chunks of sawdust from it's rear. Love this saw. No regrets. Nice work Stihl, thank you. Oh yeah, it's a lil heavy. March 20, 2015
Rated 4 out of 5 by Overall good saw Bought it new from the dealer. Got it home and could not get it started. Took it back. Flooded it. As others have posted, make sure you follow the starting procedures exactly. After that, it has run great.Saw has plenty of power. Only draw back is its weight. A bit on the heavy side.

Rated 5 out of 5 by High quality, hard-working saw I replaced a good MS 290 with this 391 as I had some larger trees coming up and my old right arm objected to the high compression cranking of the 290. I follow timber harvest cutting and use the tops for firewood, so a lot of the material is 10 to 20 inches in diameter. I also use a Stihl 260 with a 16" bar for the smaller limbs. I have both 20 and 24 inch bars for the 391 and the balance seems much better with the 20" bar. No problem with power for the longer bar, though.The saw is heavy if you are trying to cut small limbs and branches. It is made for larger material where the weight can work for you. If you are trying to decide between the pro 362 and the 391, the pro saw does have a pound advantage (less weight) as far as the power head goes. Also, the price difference between the two saws is not as much as it once was. Add the M-tronic carb system and you may want to give the more expensive 362 some serious consideration.Some have complained about the 391 being hard to start. I've not had too much difficultiy starting it as long as I catch the first "burp" and move the control lever to the partial choke level. It is easy to flood if you miss this first hit.The AV system is a great improvement over the older 290 model.I've used Stihl HP Ultra oil and non-ethanol fuel mix with good results.I've also found that keeping the chain sharp will throw chips not dust and the air filter stays cleaner. Howerer, don't neglect checking and cleaning the air filter.My 391 is about a year and a half old now and it is really a great tool. With over 100 reviews on line, about all has been said about it that can be said, but you won't go wrong with the MS 391. February 17, 2015
