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
Rated 5 out of 5 by More than enough power! I bought this MS 251 Wood Boss last fall and it cuts like a dream. Every time I go to the mountain my family and friends want to use it because it is lightweight and doesn't hurt the back. I can cut a whole load of wood without adding fuel. Thanks for a great saw.

Rated 5 out of 5 by Great saw This is my first product review ever! I have three stihl saws the newest I purchased in 1982..it is a 015. I gave it to my son to use on his property as I wanted to get a newer saw..I decided on the ms251. The saw starts with no more than 3 pulls and runs strong! Very impressed so far with this saw!

Rated 3 out of 5 by Hard to Start, but... I've had my chainsaw for a year. Used it yesterday as a matter-of-fact! Unfortunately, it wore me out before I started cutting. I can't get the thing to start and stay started! My brother owns a STIHL too and said he's never had this issue. He said, that's why I buy a Stihl. Well, for me, it's not behaving nicely. I finally got it started and it did the job but my brother was more ticked than I was and suggested I take it back! Obviously, since it's been a year, I can't do that. Not sure if I'd buy another Stihl product... though they seem to be well constructed, if they fail to start, it's worthless. Just my 2 cents. June 26, 2016
Rated 4 out of 5 by Good Saw Bad On/Off/Choke Control Lever I have an MS 650 and an MS 460 both saws are reliable starting every time with plenty of power and a solid feel. I purchased the MS 251 to limb and trim around the property and to limb those big trees when I fell them.The saw meets the demands I place on it without hesitation. What I am disappointed in is the quality of the On/Off/Choke Control Lever. I don't know how it is on other 251's because I haven't cut with them. I just know on my saw it feels like a plastic toy lever to me. I would take the saw back to where I purchased it to have them look at it but it is a 250 mile round trip for me so it isn't worth it. I keep expecting the lever to break but it has held up for a year. Just feels cheap. June 22, 2016
