    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.

    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 717.
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 4 out of 5 by from Good little saw I have been in the tree business for a couple years and stihl is the only saws I would buy I got this 170 for an extra little saw around the house and it dose exactly what I would except out of this size saw but definitely out preforms competitors in same size great for around the house clean up and small tree removal starts with 4 pulls every time cold if you know the stihl starting procedure (not hard read your manual) and starts one pull if warm overall good little saw break in took 3 tanks of fuel then noticed a little more power I use this saw a good bit and has never let me down for what I use it for

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.

Rated 5 out of 5 by from Running 4 cords strong Cut between 4-5 cord this year with the saw and pleasantly surprised with its ability to keep up. As long as you keep the chain sharp it does a good job and it's light weight keeps you from getting tired. Took at least 3 tanks to break in and notice better performance. Consistently takes about 5 pulls when cold to fire, then switch it to half choke and good to go. I had one issue consistently when it was hot out where it would not start again after refueling and quick chain sharpening (6-8 mins) or it would snuff itself out above half throttle. I learned if I took off the cover and kept it cool it would run fine every time, now that it's fall I don't have the heat soak issue. I just ran into an issue where it wouldn't turn off when I flipped the switch up, read online that a wire might have come loose and to check those, I wiggled everything I could and the issue went away. Overall very happy with the saw and love the light weight portability.
