    More information

  • 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%.

Reviews

MS 170 is rated 4.3 out of 5 by 1249.
Rated 4 out of 5 by from So far solid tool for what I am using it for. I have been let down in the past by a couple of other saws. After reading some reviews and the web sites information on usage and what type of cutting I may be doing I made the investment on this unit. Still in the break in phase of the timeline, following the extra steps of their oil and highest grade gas small mixes etc.to make sure I get off to the best start I can. Hope this one will last to make the investment worth the time and money. So far so good.

Rated 2 out of 5 by from What warranty I really loved this chainsaw for the first several months of use but when it started to continually bog down I asked my dealer if they could look it over as it was under warranty and he laughed. I am never dealing with them again.

Rated 5 out of 5 by from Perfect for around the housew Great little saw to have for around the house. It is the first saw i have ever owned, and ill tell you what. It has not failed me yet once. I've really, and i mean really pushed this little saw to the limit, and it has kept up the entire time.

Rated 5 out of 5 by from Great saw I actually have 2 now. One at work and one at home. Great saw for light landscaping and cutting wood for lathe wood turning. Exactly what I needed.

Rated 5 out of 5 by from Does more than expected Got it just for liming, and have had to ask it to cut stuff that i would normally would use my MS 290 or MS 391 and it powered right through it. I wouldn't want to use it for felling. Always start's on the 3rd or 4th pull.

Rated 3 out of 5 by from light and easy to handle this saw is the hardest starting thing I have ever owned! why can't you put the same starting mechanism in this saw as is in the BG56 blower, which starts in just two or three pulls?I would trade in an instant for that!!!

Rated 5 out of 5 by from MS 170 Bought this to replace my 10 yr old craftsman 18” this a much better saw. Starts right up, runs excellent! It could use a smidge more power if you get into some thicker stuff. But then again that’s not what it’s built for so it’s not really a negative. I still need to get a larger saw so for what this saw is it is awesome

Rated 5 out of 5 by from Cuts through wood and cuts to the point I worked for years on several high-end golf courses and have used a plethora mowers, heavy equipment and landscape equipment. There are a few that have really stood out but this is the highest quality single piece of outdoor power equipment I’ve ever owned or used. Just like a great mechanic or handyman, this saw is straight forward, honest, to the point and does exactly what it says it will do. It has been perfect for my mostly-wooded 1.5 acres and clearing several small and medium trees with complete ease. I’ve even felled a 22” DBH water oak that was just a tad over 50’. I enjoyed every minute of it.
