    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%.

Rated 4 out of 5 by A little hard to start I've only had the saw a month or so, so I really can't speak to its reliability or durability. So far it has cut everything from small limbs to 9 inch limbs with no issues. It is always difficult to get started first thing. Once it is warmed up though it starts the first or second pull every time. September 23, 2016
Rated 4 out of 5 by Great Value / bad oiling design Great value , but oiling system is very finicky . Already burnt one bar up . removed clutch checked gear, filter, hoses , pulled pump . cleaned tank , although the saws barely used .My conclusion is the pump and or passages are simply to small .Ill be looking for a higher volume pump replacement . if you can post a part # that would be sweet . Love the size and ergonomics of it and power is good for the weight . We just "Need more oil Cap'n" September 22, 2016
Rated 5 out of 5 by ONE HECK OF A SAW If you are looking for a first time chainsaw I highly recommend this one. I purchased the MS 170 over a year ago looking for something light weight over the MS 290 Farm Boss that I have and I made the right decision. I am here to tell you this is no wimpy chainsaw. When I purchased the saw it came with a 16" bar, I replaced it with a 14" bar and again I made the right decision for me. I cut anywhere between 9 to 10 chords of firewood a year for myself and others. This saw starts every time without failure. I have cut pine, maple, locus, beech, hickory, and tons of oak without a hiccup from this saw. It is great for the limbs under 14" and any tree that size or under comes down with ease. It may be a "Harry Homeowner" saw but I will stack it up against professional lightweight saw on the market. September 22, 2016
Rated 5 out of 5 by Starts with little effort and runs great. I like the chain tightening feature. I bought this chainsaw after trying two other brands. This saw starts easily, unlike the other two brands and so far I have had no problems. I especially like the chain tightening feature. This saw was a little more expensive but like many other things in life you get what you pay for and this purchase was worth it. September 20, 2016
Rated 5 out of 5 by This chain saw starts fast with in 3 pulls, cuts very well Works very well. fast start, runs good, cuts great! September 19, 2016
Rated 5 out of 5 by Couldn't be happier with this saw This truly is a great little saw. It is just big enough to tackle heavier jobs when needed while still small and light enough for your average trimming. So far it has been starting on the second pull when cold and always the first pull when warm. I had a little bit of trouble getting it to run full throttle when I first got it, but I suspect the gas that the dealer put in it was bad. After running some fresh new gas ito has been running great. Ultimately, for the money, you couldn't find a better saw for your average around the house type work. Honestly if I were out in the woods doing heavy cutting I would keep this saw on hand for the cleanup work as it is so light. September 19, 2016
Rated 5 out of 5 by Great Chainsaw! I purchased this to clean up some trees and underbrush on a lot that I purchased. Other than getting a horrible case of Poison Ivy, using this has been a great experience. I wanted to get a lighter one but for the money this could not be beat. This thing idles like a clock and never dies. It sounds like it is going to but it doesn't. I am not an experienced chainsaw user so I don't have anything else to compare it to other than borrowing another cheaper chainsaw from someone 20 years ago and there's no comparison. I think the chain is getting dull so I am going to take it in to have it sharpened but other than that I don't know what could be improved for my particular use. I would like to use it more but time and lack of things to cut prevents that. I highly recommend it. September 16, 2016
Rated 4 out of 5 by Pretty Good Homeowner type saw. I like the saw, has good power for it's size and is easy to use. The only thing I didn't like about some of the 170s is that they don't have an adjustable carburetor. The only thing that's adjustable on them is the idle. If they were adjustable they would be a much better saw in my opinion. September 14, 2016
