MS 391
MS 391 is rated 4.5 out of 5 by 232.
Rated 5 out of 5 by from Great operational saw I had a couple of new saws that I did not really care for, so I decided to trade them for another saw- a stihl ms-391. It would be a good bit heavier than the two saws I was trading in but it had a decompression button that would make it a lot easier to start. As is my usual procedure, I started the 391 out with a cap full of extra Ultra two cycle oil for the first two tanks and a little bit of Seafoam to clean out the fuel system. I let it mostly idle for the first tank with an occasional run-up to clean off the sparkplug. I could not believe how log it took to get it through the first tank of gas. It took considerably longer than my ms 271 by half again as much. It took six 15 minute sessions to get it through the first tank. On the second tank, as is my usual procedure, I let it do a little cutting. Nothing big or difficult - just small stuff. After it did a little cutting, I cleaned it up and put it on a shelf in the shop. No sooner had I put it up than the power companies tree cutting folks came back to my house and wanted to cut down a 12 Inch white oak on the rear of my property. I said fine but I want the wood.So, out comes the 391 and we spent the next two plus hours limping, bucking and stacking the tree they cut down. It got a good workout on that white oak. Actually, it only used 3/4of a tank of gas and ran the whole time. Just about anyone of my seven stihl saws could have cleaned up that tree but it gave me a good example of its dependability and abilities. Ever since then it has sat just inside my rear door, right next to my ms 261 cm, which is my other operational saw. To be an operational saw at my house means the saw is capable of being cranked on the back deck or front porch. Even on the kitchen floor if need be. Both of these saws have that capability in spades.

Rated 5 out of 5 by from Strong engine, handles great I've cut through 6 cords of wood so far with the 391 and love the power! I have a 25" bar and have cut through pine logs thicker in diameter and it never bogged down. Plus the weight of the saw isn't overbearing. My back slightly aches after cutting through a cord, but I've found that the weight of the saw helps with cutting through the logs. The 25" bar is a great length for being able to de-limb without having to bend down.

Rated 5 out of 5 by from Powerful saw, great weight to horsepower ratio and bullett proof design. I bought this saw to be my mid sized saw as I have a 291 with an 18" bar for small jobs and a Magnum 441 with a 28" bar for larger jobs. Being that I burn wood year round for our house and cabin I needed a mid sized saw for medium sized jobs/trees. This saw is amazing when equipped with an 18" bar and a rapid cut chain, it never bigs down, has a high chain speed, and pulls through any type of hard wood with ease, Oak, Hickory, Maple, Walunt, Ash, Cherry and rips through soft wood like butter. I have used this saw for 8 hours a day 4-5 days a week and it continues to amaze me with its amazing power to weight. You will not regret this saw as it is a great vallue and is the ideal all around "go to saw".

Rated 5 out of 5 by from Cut like a dream I have just about every budget saw known to man. This is a much better product by far. Fell 5 trees with it so far and one giant oak that fell on its own. Started every time and flies threw everything I have thrown at.

Rated 5 out of 5 by from Great powerful saw Ok, I've had the saw for 3-4 years now and used it each year.Saw really woke up after the first couple hours of use.With a sharp chain it chews through pretty quick...even hard maple.Starting after few months of storage isn't an issue...may take 3 -4 pulls and stall out if cold weather. Then starts and runs fine. Typically starts 1 pull after been run and warmed up.Most people problems with small engine equipment is ETHANOL fuel and /or improper gas/oil mix.Before owning any small engine equipment, find a gas station that sell ethanol-free. Get a can just for ethanol free. Trust me folks, pay the extra couple bucks. Your lawn/small engine gear will last much longer, run stronger, and you wont have expensive carb problems after sitting all winter.This saw with a 20" bar will tire you out if you're not use to wielding this lightsaber all day.
