    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 saw My previous saw was a Stihl 028 that was almost 20 yrs old. I sold it when I moved into town and didn't think I needed it anymore. I purchased a MS 170 because of the value and experience I'd had with my previous saw. It's a great saw and starts easily. It's also very efficient. It's a great saw for the average homeowner.

Rated 4 out of 5 by from Great little saw I bought this saw to keep in the truck tool box 4 years ago . It small & lite and handles most small tasks well. I've fell cedar and cotton wood up to 24"with it but that's about max for it. I've had a few small problems such as the carburetor came loose causing it to suck air, starting hard and hardly run. Tightened the screws and back to work we went. Its not a big saw but does quite a bit of work for the size.

Rated 5 out of 5 by from Everything you need for yardwork to getting firewood for heating Very happy with this chainsaw. I can cut trees up at least 48" in diameter and that's as thick as I feel comfortable cutting. My dad who has used different chainsaws enjoys this chainsaw.

Rated 5 out of 5 by from Love the weight factor and the power I great friend had one and I used it quite a lot. I had to get my own so I was not a bother anymore. He taught me how to handle it safely and I am very pleased. I bought it at Clark Devon Hardware, the guy set it up, installed the chain etc, explained it all and started it up, showed the oil flow. Great job at Clark Devon!!!

Rated 5 out of 5 by from Perfect for the Old Man My father is 88 years old and has been running saws since 1948. He is long past his logging days, but he still loves to carve his "Tikis" out of logs. The MS 170 is the perfect size for him to carve with. It's light weight and low vibration make it easy for him to control. The engine provides plenty of power to boot.
