    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.
  • Zoom
    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 from lightweight with decent power. Picked this saw up at Cal-Ranch in Salt Lake City over the weekend for some hobby work/ firewood. I was really surprised at how light it is. I spent a summer as a sawyer on a wildfire fuel crew and got used to running a 440 Magnum or 461. I was happy that it started on the first pull and was able to see a spray of oil coming off the tip. took it out back to test it on some cedar and pine rounds I had in the wood pile. buzzed right through the 14" rounds of soft fir and the new chain pulled long smooth chips. She did cut through the cedar but the saw bogged down a bit and I had to back off and take it slow. It made it through, but if the chain had been a little dull I doubt it would have performed as well. chain break stops it dead, so that's a good reassurance. After playing with it for about an hour, I cleaned her up and put her away. It was only later that I realized how little vibration I felt and my hands were pretty thankful of that. I would definitely recommend Stihl to anyone looking for a quality saw.

Rated 5 out of 5 by from The Little Saw That Could I've used Stihl products for over 30 years. Mostly pro saws but I took advantage of sale price last year to give it a try. This saw reminds me of a little dog with big dog attitude. I do strongly recommend changing the bar and chain to heavier .050 guage from the puny .043 guage. Compare the two its easy to see. Get in 14 inch. Better chain cuts better and stays sharp longer. I use it mostly cutting and clearing trees that fall on pasture fences. Nice and light but I show it no mercy.

Rated 1 out of 5 by from LOVE the MS170!!! As a female, with Rheumatoid Arthritis, STIHL is the only brand of equipment we purchase!!! My husband's STIHL Farm Boss (290 - now retired) chain saw was way too heavy for me to use so my mom surprised me with the 170 for Mother's Day 2016. The 170 is lightweight enough for extended use by female; yet sturdy enough to tackle heavy jobs. For example, I cut down 250-300 medium sized cedar trees over the course of two days with no problem or engine trouble. The key is to have extra chains on hand (which can be re-sharpened) and add bar oil with each refueling. With those three things, the 170 will run forever!! The biggest bonus for us also is that all of our STIHL equipment starts every single time we use it (which is a HUGE bonus because I despise small engines that won't start!). I will add that we currently own a variety of STIHL equipment (3 chainsaws, a pole saw, a weed eater, a trimmer, a leaf blower, and a tiller) and we are 100% satisfied with ALL of it!! We absolutely LOVE the STIHL brand for all of our ranching small equipment needs.Note: we run STIHL bar & chain oil & STIHL fuel mix in all of our STIHL equiment. Always!!

Rated 5 out of 5 by from Played with it a few times but haven't cut wood yet. Feels great, very solid, but haven't used it yet.Oddly enough I didn't type enough, so I have to type more so it'll let me post this? Really? That's annoying. Hopefully this is enough.

Rated 5 out of 5 by from Light weight but plenty of power I had big saws for the trunks but needed a smaller, lighter saw for the branches. This one does the job admirably. I also appreciated the on line video on how to sharpen the chain.
