    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.

    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 3 out of 5 by from Love the product, checking out the warranty. I have two other STIHL chainsaws & Love them. So I bought this MS170. Now after about 15 to 20 tank fills it just slowed down & died. I tried to restart it with no luck, so I took it back to the dealer. He is looking at it too determine what happened & if it's covered by the warranty. I hope so because I've only had it for a few weeks. This is about the twelfth STIHL I've owned & never had an issue before this. At this point I don't recommend this product, but if they cover the warranty & it's just something minor then I would.

Rated 5 out of 5 by from Very good for occasional home owner use. Unfortunately, my 3 year old MS170 was stolen. Looking for one as good again as that one, which I bought on a special day when some Stihl reps were at a local supply stores special day and got a really great special price that time. Guess I'll have to pay the real price this time around. Just having one that will crank and go when you need it only occasionally is worth the price. Thieves usually get their rewards eventually, a few years inside a concrete room with bars for a door.

Rated 5 out of 5 by from Very nice product. This Chain saw has a mighty punch for a little guy. Even though I have only had this product a short time, I have used it on quite a few projects and it performed very well. I sure hope over time it holds up to the Stihl name. The weight of this device (light) made it easily used by this female. I was also very impressed by the sales person at Oakdale Ace Hardware in Smyrna, GA. He reviewed (physically showed me) the operation and safety of device in a non-condescending manner. Sometimes people are very condescending to women buying these types of products.

Rated 3 out of 5 by from Lightweight easy to handle The only disappointments were in the handle when tilted on it's side cutting small trees off at ground level. The trigger on the handle seems to "catch" and not let me fully open up the throttle. When upright there is no "catch" so evidently something in the handle either moves or tilts and thus catches on the trigger keeping it from fully opening the throttle.The power isn't as great as I was hoping but I am used to the MS 270C that I had.

Rated 5 out of 5 by from Stihl MS170 and Village Hardware, Idyllwild is a great combination I needed a new chainsaw for limited home owner use. I contacted Larry at Village Hardware, Idyllwild, and spent 30mins getting great advice. Clearly, a Stihl saw was a dramatic upgrade over my previous generic experience, with Larry's guidance I also purchased a safety gear set. Importantly, the tutorial of how to use the saw and the full set up, so that I left the store with the saw fully operational meant that I was instantly ready for yard work. First time out the saw was fantastic, did what I needed, no issues, I'm anticipating many years of Stihl quality - thanks for a great product and knowledgeable dealer.

Rated 5 out of 5 by from Better features than my older Stihl shainsaw MS170 has better fuel and oil caps than my older Stihl saw. Also has a better design of the chain tension adjustment. It is also lighter with less vibration so less fatigue with continuous use. I purchased this saw for trimming trees, but It does have adequate power to cut a stump to ground level with the bar fully loaded. This MS170 is easy to start just like ALL Stihl products. This is a great entry level product for the average homeowners.
