Rated 5 out of 5 by Awesome saw for the money. I could not be happier with my Wood Boss. Great saw, starts every time, cuts like a champ, couldn't ask for much else. August 12, 2016
Rated 5 out of 5 by Great quality product I bought the MS251 in 2014 to remove trees and debris from my rental houses and property. My dad always told me Stihl had quality products so I figured I would buy one and try it for myself. I have used Poulan and Jonsered saws at work and I would say the Stihl to me is the best. It has a great quality feel and made in the USA which is important to me. Starts up everytime when I crank it like the directions say. I see why my dad says nothing comes close to a Stihl. The real test will be when we get a hurricane and have to remove pine trees from the roads down here in Florida which will be fun with this saw. I would recommend this quality saw to anyone.

Rated 5 out of 5 by 251 I just upgraded from a stihl 170 (which I have bought 5 in the last 8 years. I cannot complain about the 170 because I cut 50-70 face cord of wood a year from 2 inches to 30 inches in diameter.I know I asked a lot from that small saw. After running 2 tanks of gas through the 251 today I had 3 times the wood cut. Never had a bit of trouble starting it. I highly recommend the stihl chainsaw. August 3, 2016
Rated 2 out of 5 by Not a successful work day yet. I bought my new stihl last month. I researched the products, I read the reviews. I went with this one based on power, weight, and price. I live over 100 miles from town. I was excited to use it. The first trip to cut wood there were three of us. I ended up having to use a cheap Walmart saw ( that was starting and cutting all day) because mine would not start. When I returned it, I was "taught" how to use it. So I swallowed my pride and made sure I was starting it correctly. The second trip it started smoking and the tension bar had to be tweaked, once that was better it still smoked. After testing it and watching for oil, there was no oil spray. I had read that there was not a lot of spray, we found none. Manually oiling the bar kept it from smoking but before I had finished my first tree - maybe 6 rounds total for the saw- my blade was dull. I have not had a good experience and I will be returning the saw. August 2, 2016
Rated 5 out of 5 by Good for what it's designed to do The wood boss is a quality saw, of course it has its limits and wouldn't be what u choose for large diameter trees but it does everything else well. No complaints. July 25, 2016
Rated 1 out of 5 by Great saw...if you can get it started 1st time I went to use this saw, it would not start. I had to borrow the neighbors cheap Poulan Pro saw. Very disappointed with this purchase. July 21, 2016
Rated 4 out of 5 by Good saw for what it was designed for I purchased this saw for brushing, campfire wood, and general homeowner needs. The saw starts right up, runs great and cuts good. The only thing I have an issue with is the chintzy choke lever. It feels like it's going to break every time I move it. July 19, 2016
Rated 5 out of 5 by Excellent mid power chainsaw I bought the Ms 251 about a month ago. It took me a while to understand the Ematic oiling system that stihl saws use now, because I have been use to the oiling systems used on husqvarna saws.-if I cannot write my name with the oil coming off the bar then the oiling system is not working properly. With the Ematic oiling system the MS-251 consumes about one-half the bar and chain oil that I am accustomed to with my other saws. In other words, if I burn a tank of gas, the 251 will consume about one-half tank of Plat I'm bar oil. The same holds true for my new MS-170. At first, I thought both saws were getting ooiled, inadaquately, but such is not the case. Anther plus is the lower use of bar oil makes them much easier to clean up than my slobbering Husqvarna saws. Unlike some folks, I clean up my saws after each use.I use stihl "ultra" two cycle oil mixed at, exactly, 50:1 using non ethanol, premium 93 octane gasoline. None on that ethanol gas goes in any of my two cycle equipment. I also use stihl' platinum bar oil in my stihl saws. It keeps my bars and chains cool and wear to a minimum.Cranking a 251 is easy. I set it to full choke when it is cold and pull until it rolls over which is usually in about two pulls. As soon as it rolls over I push it up till I (run position) and pull until it starts, several more pulls. If I have been using it and it is warm, I just push it down to the ignite position and pull. It usually re-start with one pull.Adjusting the chain on a stihl saw is a little more time consuming than on other saws, but they are adjusted in the same way. The only real difference is you have to make sure the chain is on the sproket and not wedged between it and the outside spacer washer. This is why I rotate the chain, forward, as I am adjusting the chain to make sure it is still centered on the sproket. Normally, I just hand tighten the side cover nuts and this normally will center the chain on the sproket and bar groves. I also rotate the chain with a gloved hand or folded shop towel, forward, to make sure everything is centered up probably, before I begin adjusting the chain tension if anything feels amiss I disassembled everything and start over.I do not want a chain to get stuck between the spacer and the sproket. I also rotate the chain forward a few times after it has been adjusted to make sure everything is working properly. If I have time and not to tired, I often crank the saw to check it's operation before I slip the bar cover back on and put it to bed. July 17, 2016
