The updated MS 170 features:

The MS 170 chainsaw is equipped with an innovative IntelliCarb compensating carburetor that automatically adjusts the air/fuel ratio when the air filter becomes clogged or restricted. This feature ensures that the engine maintains the correct RPM without pulling in dirty air to deal with it, resulting in optimal performance.

Furthermore, Stihl’s anti-vibration system is integrated into the design, which helps to reduce operator fatigue and provides a more comfortable working experience.

When paired with Stihl’s Oilomatic saw chain, the Ematic guide bar delivers the right amount of lubrication to the required parts. This design results in up to 50% less oil consumption than other models due to the ramps on the bar rail that contain the oil flow and direct it to the necessary areas.

Here is a list of the updated features and changes of the Stihl MS 170 chainsaw:

  • Increased engine power of 1.3 kW compared to the original 1.2 kW
  • Reduced fuel consumption by up to 20% compared to the original MS 170
  • IntelliCarb compensating carburetor
  • Improved air filtration system for longer filter life and improved engine performance
  • Upgraded anti-vibration system for reduced operator fatigue

  • Redesigned chain brake for improved safety and easier maintenance
  • Upgraded sprocket cover for easier chain adjustment without tools
  • Redesigned starter rope and handle for easier starting
  • Improved muffler for reduced emissions and better sound quality
  • Updated color scheme with new Stihl branding and design elements.
