    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%.

MS 170 is rated 4.5 out of 5 by 459.
Rated 4 out of 5 by from One very significant flaw The one bolt/nut design for tightening the chain is efficient, yet it wasn't solidly adhered into the plastic body. I have plenty of saws and know not to over tighten when changing chain tension. The darn thing was loose and started coming right out of the plastic housing. It was repaired by my STIHL dealer after pressing Blue Mountain distribution. Because I have several STIHL products, they may have made an exception for me. It should be covered by warranty and should be solidly manufactured.Now that it is repaired, it is a good little light weight saw that I use on light work.

Rated 5 out of 5 by from Great little saw ! Purchased this saw to use for limbing trees because of weight and size. I have ran this saw everyday for the past few days and it works great ! Oiler is set perfect it uses one tank of oil to every tank of fuel. I've cut limbs 12 inches with it and not a single hick up. I had dealer replace the 16 inch bar ( I feel which is a little much for the hp this saw has ) with a 14 inch bar as long as you let the saw do the work as with any chain saw it works perfect. For the money you can't beat this saw. I will be adding at least one or two more of these to my saw fleet.

Rated 5 out of 5 by from Excellent homeowners saw This saw is perfect for jobs around the house and for cutting firewood. I've tackled all types of logs with with this saw. It is very dependable, starts quickly and requires very little maintenance. The chain stays sharp through extended use. The Stihl file guide tool makes sharpening quick and easy. This is one of my favorite power tools.

Rated 5 out of 5 by from Very good saw My great uncle gave me this saw when i was 13 years old. I used it all the time. It cut everything from a twig to a tree wider than the bar. This is the saw that made me a firm believer in Stihl products. When i was 16, I had parked my fourwheeler on the side of the road with my chainsaw on the back of it an i walked up a trail into the woods and when i got back my saw was gone, someone stole it. I was heartbroken. I saved up my money for a few months after that and went and bought a MS 250 Stihl. And its a perfect saw but, itll never be the 170 that I grew up with.

Rated 5 out of 5 by from Great saw for the homeowner Purchased this saw after another brand of new saw only ran for 3 minutes. This saw starts quickly and just works. Hard to beat the Stihl brand these days.

Rated 5 out of 5 by from Great value and excellent saw I rate this saw number 1 absolutely great quality. I buy nothing but stihl products hands down no comparison to any other brand. I highly recommend any Stihl product to anyone. I love my saws, trimmers , weed wackers and blowers. Thanks Stihl im a lifelong customer no doubt.

Rated 5 out of 5 by from No complaints here other than I wish I had bought a bigger saw This being my first saw and not knowing what to expect I started small and went easy on the wallet. I knew Stihl had a good reputation but there's always that doubt until you take the leap and make that purchase. Well let me tell you I'm very pleased and regretful at the same time. Pleased that I bought a Stihl which starts effortlessly and does exactly what it's supposed to but I regret not buying a bigger one. This saw is great on small trees and limbs but if you need to cut anything even medium size I'm afraid this saw is not going to make the cut pun intended. I've only used the saw maybe a half dozen times and I'll update the review if necessary in the coming months if anything changes.
