    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 1 out of 5 by from Poorly made Purchased the 170 due to store recommendation. Used the saw 7 times and according to the store I purchased it from and Stihl themselves, the saw is unusable due to to chain brake failure and melted parts. The first time I used it I cut five small limbs from a peach tree and the carb ended up with saw dust in it. I had to take it in to have the carb cleaned and serviced. I was told to be more careful. There should be no way for saw dust to enter the carb! I am no stranger to chain saws and how to use them and take care of them. I followed ALL the instructions for use and care. Stihl refuses to help and therefore I will NEVER buy another product from Stihl!!

Rated 5 out of 5 by from Great saw Had some pine trees fall recently and it was cheaper to buy this saw than have someone else do it. Was even more impressed with the price when I compared other brands offered at the big boxes.Have use it a couple times and always starts on the second or third pull. Cuts through green wood with ease.Fantastic saw, wish I had bought one years ago.

Rated 5 out of 5 by from The only chainsaw you’ll ever need I bought this as my first chainsaw and I have a feeling it will outlast me. If not I already got my money’s worth out of it. It is lightweight yet I have turned 24” diameter oak and ash trees into firewood with this little “beginner saw”. Just sharpen the chain every ten or fifteen tanks of gas, which is easy to do, don’t force it through the wood, and it will keep on going. A chainsaw is one of these tools you don’t want to buy online. I had a problem early on, which turned out to be pure user error on my part, misunderstanding the starting procedure somehow. My Stihl dealer changed the gas free of charge, found nothing wrong with it, showed me how to use it, and sent me back on my way. I am near the end of my second gallon of chain oil, which probably translates to well over a hundred tanks of gas, and many cords of free firewood.

Rated 5 out of 5 by from Great starter saw I purchased this saw for keeping 5 acres of Colorado mountain woods (Pine and Aspen) cleaned up and keeping me in firewood for the winter. The 16 inch length is fine for all but the largest trees on my property.This model (MS 170) is slightly underpowered for my needs. Not a reflection on this saw, rather my miscalculation on what would be required for this job. This saw is very light and nimble, can run it all day without fatigue. Low level of vibration, well balanced.I am so pleased with it, that I purchased a larger model (MS 291) this week. Between the two, I should be in great shape for years to come.

Rated 5 out of 5 by from Great Homeowner saw I was looking to get a gas powered to replace my 14" electric and was considering another brand available at the big box stores. My brother, who has extensive experience with chain saws told me to stay away from the brand I was considering and suggested I look at Stihl. When I saw I could get a Stihl for a great price I jumped at it. The people at Thruway Ace hardware were great and the saw is every bit as good as advertised. I don't know how I would have made out with the other brand and now I suspect I never will.

Rated 1 out of 5 by from Crappy saw regret the purchase A friend of mine recommend this saw to me. I needed something smaller for limbs and cutting smaller trees to compliment my bigger saw. They had me purchase the Stihl mix so I could get a 2 year warranty over the standard 1 year. Got it home excited to get some work done. Ran a tank through it and it was spitting oil out the muffler. Have about 5 tanks through it now and it won't idle. Very frustrating should have did what the reviews said and went with the Echo CS-310. Not to mention they have standard 5 year consumer warranty.

Rated 4 out of 5 by from Great saw for the price Runs and cuts great have zero issues with the saw and have used it to cut up several 12 to 14 inch logs. Only complaint I have with the saw is that it does not come with any steel logs dogs to help roll the bar through what your cutting and the saw dont bite with just the plastic one made into the housing of the saw

Rated 4 out of 5 by from Not bad for the price. Won this saw in a raffle. I own a redwood burl business and have been running Stihls for 45+ years. I use 090's for my milling.Best saw they ever made!! Got this saw and was told by my local saw shop that this is Stihl's cheap homeowner saw. He told me that they are made in China for Stihl and have a unit cost of $5 each to build. Well, for a free saw that costs $5 to build, it runs pretty good. I have put a couple of dozen tanks of gas thru it working, trimming roots off stumps and trimming table slabs for hours on end. It is under powered, but that is to be expected for such a tiny powerhead. Two things you need to know to make it last. #1 never run it at full throttle for more then a few seconds at a time. This saw will blow up if you run it wide open for any extended period. My saw shop mechanic's advice. #2 I mix my gas a bit rich. The old 090's like a richer mixture compared to the new saws that run on a leaner mix. I use Stihl high performance mix( the orange bottle) and mix 5 gallons at a time. I mix 4.7 gallons of regular 87 octane gas per bottle that normally mixes 5 gallons. This richer low octane mix works fine with my saws. I have old 090's, some of their competition, newer Stihl 046, an MS250, MS171, and MS170. All of these saws have run tank after tank of this mix ration and I have had no problems. The only saw that I have that is a pain is the MS250. It starts right up, runs great, but shut it off and let it sit for more than 2 minute and it refuses to start and will flood out. You let it sit for half an hour or more, and it fires on the 2nd pull. Can't tell you how many times I have wanted to throw this saw across the yard! In my professional opinion of running chainsaws since I was in grade school( Im 48 now) running your saw,any saw, at 3/4 throttle is best unless you have it buried and under a full load, than you can run wide open. Also running the gas mixed richer seams to work well. All the saw manuals now want you to run hi octan and lean mixes or they want you to buy their Premixed alcohol free gas. That stuff is $$$. A quart can cost like $5-6. That is ok if you are home owner and use the saw once a year or so to cut up a couple of fallen limbs. Any one else mixes their gas. You run a saw wide open on high octane lean mixed gas and you are just asking to blow the saw up. Take it from me, run slower, richer and you for sure will be running longer. Like years longer.

Rated 1 out of 5 by from Horrible unit I had 2 maples taken down in my back yard & needed a new chainsaw to do brush, limb cleanup, small type branches, average say 6 to 10 inches. Purchased new, ran at the store, Runnings when picked up, got it home, ran for about 3 hours, on & off, very little idle. Shut down for the day, tried to use it the next day, would not start after many pulls, chokes on & on. Took it back, fowled plug, put new plug in, great, took it home with several spare plugs since was stated maybe a break in period thing? Got it running the next day out, worked for about 45 minutes. Shut down to add fresh fuel, yes, mixed fuel, Would not restart. Put new plug in since that one was fowled too. Got it running for a while longer. Shut it down, went to restart, would not restart. Took it back to turn it back in, return it to get my money back. Was done messing with it. Was told the 10 plus other units on the rack there were all awaiting service due to running issues, all 170's. I bought a Stihl because are to be one of the best, but never again. acquired another from another, have been using it now for a week, no issues at all, starts every time. Sorry, this product sucked & did not need to spend many hundreds of dollars on a higher unit since this is for occasional use, not commercial use. Too bad.....

Rated 5 out of 5 by from Versatile Saw for Quick Jobs yet holds up well for long sessions My very thoughtful wife insisted I get another chainsaw as backup to my MS 251 Wood Boss, and as a bonding experience to allow my adult grandson to share work with me, so I chose the 170. (Recently, we had both saws running for 4 hours straight, stopping only to refuel.) As a 'homeowner' tending to more than a thousand 30-40 year old (pine, ash, elm, locust) trees, I find this 170 is really handy for delimbing trees downed by the 251, though it can also handle big stuff on its own. The thinner bar makes for a quick, clean cut with somewhat less effort, and the lighter weight is quite maneuverable compared to the 251. My only disappointment is the lack of true bucking teeth; these plastic bumps work OK but won't dig in like real teeth. All said, the 170 with its 16-inch bar is a great saw at a good price.

Rated 2 out of 5 by from It's the right saw for me, as far as size and weight, but it has run poorly from the beginning. Bought my MS 170 a year ago and I love the saw, as far as size and weight, but I hardly use it because it runs terribly. No power and doesn't want to idle properly. My son has the exact same saw and I've brought down 4 cords of wood this Spring...all with my son's MS 170. I took mine back to the dealer (Plaza Hardware in New Tripoli, PA) and complained that it had never been set-up properly. They just told me the air filter was dirty and, in their opinion, nothing was wrong with it. To this day, the the two saws run noticeably different when side-by-side. I have a retired friend who has cut wood professionally and he noticed how poorly my saw runs, compared to my son's MS170, so it's not just me. HELP!

Rated 5 out of 5 by from Fantastic little saw I have owned and used this saw for several years around my home and it has proved more than capable and is priced well. You can bury the bar and it cuts well. With a 16 inch bar I often have to work a log from both sides but anything under 32 inches (Which is pretty big) gets cut up without much fuss. It is also very light and manageable. A fantastic saw for a new sawyer. I recommend this saw to all my homeowner friends and family every chance I get.

Rated 5 out of 5 by from Best Buy Had this saw for a year now, and STIHL love it. Over the year, ive cut down, and up over 30 large trees for firewood. Most over 18" in diameter.....with the 16" bar. Also cleared 4 acres of 8'- 12' river privet. My only problem was about a month ago, it had trouble running at an idle. All I had to do was remove the spark screen from the was gummed not bother trying to clean it, unless u like a headache.We can thank California for that issue. As long as you remove the spark screen, and clean out the air filter as needed, you will be just fine......and did I mention it is the lightest saw ive ever owned!

Rated 4 out of 5 by from Great little saw! Bought this saw a few days ago to cut a house lot. Runs good for what you pay. My local dealer told me to try it out on some 12 inch stuff and i was surprised to see how well it did for what it is. Not the fastest saw to buy but does a great job.

Rated 1 out of 5 by from Terrible Experience Purchased 10 days and used once and is now dead. I had on earmuffs and fired this 170 up for the first time and it roasted itself. The chain brake was on and I apparently did not pull the trigger to get it out of WOT the break roasted the saw. True Value said I had to pay to rebuild it I was like it was on for 60 seconds. No help it never made a single cut. true Value can not afford to make a 30 day exchange on saw. the saw never made a single cut. True Value in Salem VA
