    Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

    IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
  • Zoom
    Ematic™ Lubrication System
    The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.

Are You Ready for a STIHL?

MS 170 is rated 4.4 out of 5 by 750.
Rated 5 out of 5 by from So far, so good. Light, starts EZ and cuts nicely around house. After several back surgeries I had to let my Farm Boss take a break for a few years and finally sold it to a friend. I moved from a home with some acreage into a small subdivision with lots of trees. The MS 170 has been doing the job with fallen tree tops, limbs smaller trees. I highly recommend it for lighter duty.

Rated 5 out of 5 by from This saw is light weight and easy to use. I've been wanting a saw like this one for some time, For around the house, and to go out and cut some firewood it's great. I did some research about the size I needed and for the price it's prefix.

Rated 5 out of 5 by from 2 months in I’ve had this for 2 months. I run other Stihl saws, (290, 362, 441)I use this for around 12” logs and down to cut for firewood. Works great and is light. Doesn’t weigh your arms down.

Rated 5 out of 5 by from lots of power This saw is an excellent product. Has a lot of power for its size. I filled it with recommened bar oil and fuel mix and used it all weekend cutting firewood. It cut thru small limbs and large limbs with ease. I used it on the main trunk, some places as large as 12'' and it didn't even slow down. GOOD SAW.

Rated 5 out of 5 by from Nice Addition I bought this saw to take on the back of my atv and use it to clear red cedars from the property. Added the extra chain and case which is a big plus. Saw has been super dependable and believe it or not I have yet to use the spare chain. Probably ran about 20 tanks of gas so far, zero complaints. Much nicer than having to use my bigger heaver saw all the time.

Rated 5 out of 5 by from Great saw for the money I bought this during Stihl's promotion last year. It has exceeded my expectations in all ways. It cuts outside its weight class and has been 100% reliable. What's not to like?

Rated 3 out of 5 by from The saw is good and bad. The saw does the job; however, after I use it and put it in the case, it leaks oil. When I get the saw out of the case the next time I use it, I have to wipe off the bottom of the saw, and wipe the bottom inside of the case. I have had the saw back to the dealer twice. No fix. The customer service rep I complained to wanted me to ship the saw to him. Then I would be without the saw for how long??? Not an option for me at this time because I need to use it. I have not made a decision regarding my next move, but I will keep making an effort to correct my problem.

Rated 5 out of 5 by from Great saw I bought the 170 as a second saw for trimming,pruning and firewood cutting. I put 12" bar on the saw. Great saw,lightweight,dependable. I use the 170 more than I thought because it cuts well and I don't get fatigued using it. I would recommend this saw for homeowners who want a great saw for cleanup or cutting firewood. Between myself and 2 sons we own 5 Sthil chainsaws.

Rated 5 out of 5 by from Bad reviews on starting are unwarranted. I read reviews that complained of hard start, my question is did they think possibly the gas may be the problem. 1st thing to trouble shooting are the simple things like dump old gas, change sparkplug. People would be amazed.

Rated 5 out of 5 by from Best saw I ever owned I've had many chain saws in my life--big ones and little ones. The little ones are easier to use and don't work you to death. I bought my first STIHL, a 16-inch MS170, last year after my Poulan died. In all fairness, I didn't know what a real chain saw was until I fired up the Stihl. The first time out, I ran it for about 4 hours. In all that time, the chain never stretched. I didn't have to adjust it even once during those 4 hours. The saw is easy to start and just keeps going. This is one of the best tools I have on our small farm of 14 acres.

Rated 5 out of 5 by from good saw its a good little saw for around the house all I use it for is cutting fire wood and im very satisfied I put a 20 inch bar on it the MS 170 will handle it as long as you don't try to push it to hard

Rated 5 out of 5 by from Dynamite in a box When my wife purchased this chainsaw for me i knew her intentions....cut down that 50 year old overgrown Elm in the yard.This little saw cut it to pieces and to the ground like nothing.Even severed all the roots before I needed a new chain. Its smaller size made it easy to handle when up in the tree, Incredible underrated saw can do more than promised.

Rated 1 out of 5 by from Disappointment I recently purchased a Stihl MS 170 this year when they were on sale. It has turned out to be a disappointment for several reasons. It started fairly well when it was new which was my main reason to select Stihl again. I have had a Stihl blower for several years and use it frequently and it is always easy to start. The chainsaw, not so much. I have less that 4 hours on it. Today I tried to start it and noticed the motor would run but the chain was frozen. Dismantled the cover only to find the clutch was bound up, worked on it for an hour with no success. I would normally take it back and have a repairman try to fix it, since these aren't cheap but, the repair is 70% of the cost to buy a new one. This saw was never abused and broken in by the book. The homeowner line is just not anywhere near the professional quality. Totally disappointed with my purchase.

Rated 4 out of 5 by from Great First Saw This was my first chainsaw, now I have three because my experience with this saw infected me with chainsaw fever but left me wanting more power. It is simple, lightweight, and smooth to operate and I am glad this is what I learned on since it is small enough to make mistakes and recover before suffering an injury while bigger saws are not as forgiving. I would prefer an adjustable carb. I would suggest downsizing bars I am using a 12" Stihl bar and chain and it is a much better cutting experience. I think dollar for dollar it is as good as a saw gets.

Rated 5 out of 5 by from Glad I bought it Bought the MS170 after I got truly sick of trying to start my 30-year-old Brand X. Notwithstanding complaints I've read, the MS170 is easy to start and goes on the third or fourth pull if you follow the owner's manual directions. So far I've run about three tanks of gas through it, cutting pine slash from the local mountains and oak deadfalls at the ranch for firewood. Needless to say, goes through pine like hot butter, but it does very well on 6-8" seasoned oak logs too. Well balanced, plenty of power (although not fully broken in yet), light, good homeowner saw. I typically use it about once every other month.

Rated 5 out of 5 by from Stihl vs African Bush I tend to overthink most things combined with a tendency for passion bordering on obsession for things I find interesting. Recently married & borrowed my father in law's MS 382 to cut down fallen trees blocking dirt roads on our private game farm outside the city (which we visit on weekends). Whilst this saw made short work of anything in its path, it was heavy & very few of the trees exceeded 15 inch diameter. I also hate having to borrow things for many reasons so I decided to buy my own Stihl. Went for the 170 as it is light weight & 90% of my work on the farm is small to medium trees.If you have any chainsaw experience you'll know that the weight of a saw really does matter. I can go all morning cutting with this saw before I start to tire. Just love this saw.I meticulously clean it after every use & make sure that no fuel is left in the tank / carburettor after each use. The saw pays me back for my efforts in reliability. Leaving no fuel in any two stroke machine after you use it is the best chance you'll have of never having reliability issues. I also enjoy sharpening the chain with my Stihl sharpening kit after a hard day's cutting.Can't see myself ever needing anything more than this.Even though this is a small saw, I purchased my Stihl helmet, face shield & ear protection and also use steel toe wellingtons & leather gloves. As they say, when it comes to chainsaw accidents / injuries, there are no small ones of either...

Rated 5 out of 5 by from This chainsaw is awesome. Starts very easy and very light weight. It eats through anything I throw at it. Excellent power for the size of saw. I recommend this saw for any home owner with moderate cutting needs and does’t break the pocket book.

Rated 2 out of 5 by from Powerful IF it starts. Apparently, the lower end chain saws aren't worth the price, I recommended Stihl to a friend & we have constant problems with it. The 170 gets run about 2-2 1\2 hours at a time & every 3rd time, it will either not start or not run very long. I was told by two service techs at two different locations that it is air leak problem in the gas tank on line. If this problem is that obvious, why hasn't it been corrected? I've run older, larger, more expensive models and loved them. This makes it hard to recommend the lower end products!!

Rated 5 out of 5 by from Surprisingly Durable Lightweight Saw Overall this saw is extremely useful, both for professionals and homeowners. Working in the tree care industry since I was 13, I have plenty of experience with saws. We purchased the stihl ms 170 in early 2015 just to see how such an affordable saw would preform. After nearly three years of almost daily use and abuse, being dropped in a stream while running, dropped 20’ out of a tree onto concrete, and probably a few more things I don’t know about, it stihl runs like new. (I did have to replace the top handle after dropping it out of a tree) Sometimes it won’t want to start, so just give it a few pulls with the throttle wide open until it starts.If you’re considering buying this saw, I would say go for it. However, If you’re absolutely new to chainsaws, take a training class or ask a friend to show you how to safely start and operate one first.

Rated 2 out of 5 by from VERY COMPLICATED AND HARD TO START First day review: WOULD NOT START. I made 50 or so pulls , all I got was noise most of the time, other times NO noise at all, and no start either. Finally it just started. No rhyme or reason, but after I shut it down, it was back to not starting. There seems to be a lot of things to do to get this saw to "be a saw". I've been reading other peoples reviews, and can't really comprehend why someone would say "it's EASY to start". At this time, I will not in good conciseness, recommend this product. AND STIHL- You don't need to reply to this because I've already heard all you have to say on other customers reports. AND this is ALL you ever will say: "Response from STIHLCustomer Care , Customer CareVery sorry to hear about your experience with a STIHL MS170. Please contact the STIHL Customer Care Center at 1-800-467-8445 (option 2) to see how they may assist with any concerns or questions you may have." - Why would I need to contact "STIHL Customer Care Center at 1-800-467-8445 (option 2)" when the reply came from " STIHLCustomer Care , Customer Care" ??? Anyway, it's going back to the dealer today. That's all for now.
