    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 5 out of 5 by Great beginner saw for small jobs This saw caught my attention with it's great affordable price when I needed it the most after hurricane Matthew. I was actually in the store to buy new plug ends for running generator. I have had other brands of saws over the years but have never owned a Stihl chainsaw. I have been a loyal customer with lawn equipment but could never justify the cost of the bigger saws. You will not be disappointed if you occasionally need to cut small trees and branches. I am now looking and saving up for one of this saw's big Brothers. October 25, 2016
Rated 5 out of 5 by Lillte Powerhouse I really like this saw due to its size, power ratio and handle location small around the backyard tasks. Usually will crank on two pulls and overall just has a nice fell to it far as weight and handle placement. I also bought the bumper plate for this saw which personally feel it should come it because it adds a layer of protection from the bar kicking back. October 18, 2016
Rated 4 out of 5 by Good for light weight work around the house. I find the MS 170 to be a capable saw for the use of light wood cutting work. I personally prefer a saw with more power. This saw is perfect if you are trimming small trees and branches but I would not recommend it for cutting of firewood for ones personal use. It functions exactly as described in the catalog and perhaps I over estimated the power when purchasing. All in all, a good saw that I would recommend for someone who need merely to maintain a small property with small limbs and trees to trim. October 18, 2016
Rated 4 out of 5 by Good little saw! Nothing is perfect, hence the 4 stars. Great little limbing saw. Good power, for its small size. I've had to replace it under warranty, but Stihl stood behind it, and the replacement has been excellent. Starts right up, and goes right to work. When I'm cutting downed trees (I volunteer as emergency fallen tree response in a wet and windy environment), my kid can run the 170, while I run my bigger saw. I would buy this saw for any small wood cutting jobs. October 17, 2016
Rated 5 out of 5 by Great little utility saw I have been buying and using saws of many different brands in this class since the early 70s and the MS 170 is about the best that I've had.It's easy to start and easy to use and just the ticket for tree triming or light firewood cutting. I bought the 170 last spring and so far it hasn't given me any reason to complain.About the only thing I would change is to give it a little more power. The saw is not weak by any means but on full cuts in hard wood like oak you have to take your time or the saw will bog slightly. But then this saw wasn't bought with heavy use in mind, we have an MS 271 and it does a great job on the larger stuff.The MS170 is a good little utility and tree triming saw that will do fine cutting a small load of firewood now and then.

Rated 5 out of 5 by Great little saw lasts forever Bought this saw for the ice storm in 2014 for smaller stuff and limbs. No complaints what so ever have used what seems like a million times with no problems what so ever. For the money you really can't beat it October 17, 2016
Rated 2 out of 5 by Underpowered I bought this from Ace Hardware for cutting down tress for firewood. It was unable to cut anything more than six inches without bogging down and getting stuck. It also flooded several times making it difficult to start. I returned it and purchased an 18" Stihl with easy start. A review will be posted on this saw later. October 15, 2016
Rated 5 out of 5 by WOW! I have had this saw for over a year now and use it quite often. It still starts every single time I need it. Maintenance is a breeze and if kept up this saw will probably last forever! October 13, 2016
