MS 170

MS 170
A lightweight chainsaw designed for woodcutting tasks around the home.

Product Description

"I am very satisfied with every aspect of this saw and love how light weight it is. It starts easily and runs great. I have cut up to 16 inch diameter oak, and it did a great job, considering the size of the saw. The local dealer was very knowledgeable and very helpful."

    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%.

Rated 5 out of 5 by from Great little saw This saw started up right fro the dealer and has cut flawlessly since. Have cut about fifty smaller trees and the chain has only been sharpened once. I would buy this saw again.

Rated 5 out of 5 by from Little work horse I bought this chainsaw for working around my property. The functionality is easy and very dependable. I used it for cutting hard woods and pines, and didn’t have to sharpen the blade until I was 4 1/2 hrs into cutting mostly hardwoods. That says a lot about a smaller chainsaw. The only issue I had with the setup was the plastic grip teeth at the base of the chainsaw. I went back to the business I bought it from and they added a metal accessories for free. The 180 has the metal teeth but the add-on saved me from having to upgrade. The 180 was $60 more and I didn’t like the chain bar setup. I love my 170! I think you will love it too. Buy it without any concerns but add the metal teeth. Best of luckJ. C.
