  • 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.
  • Side-Access Chain Tensioner
    The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
  • Translucent Fuel Tank
    Allows operator to easily check fuel level before starting work.
  • Toolless fuel and oil caps with retainers
    Simply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.

MS 171 is rated 4.2 out of 5 by 119.
Rated 5 out of 5 by from Great saw - very effective for larger trees than I thought possible I have happily used a still ms361 ( my "light saber ") and ms441 Magnum for years. But have begun back-country hiking and biking trail maintenance. So I bought this lighter MS171 saw to backpack ( in the often several mile hikes ) and clear trees down on the trails. Many reviews mention that this saw is for occasional use and small trees. But I have been surprised at how this saw will chew through 12 to 20 inch logs - even aged dead oak logs that are extremely hard wood. i am now happy to depend on this saw for all trail maintenance trees - unless a large tree "mess" dictates that I need to carry-in a larger heavier saw. As others have said, learn to sharpen the chain. It is small in width ; but that small width allows a small motor to drive through lots of wood. Keep extra fuel near, as the gas tank is much smaller than the pro saws. I use premium 100% gas with the new grey bottle stilh mix and have not had any problems starting. This is a great saw if one is patient and allows it to chew through wood at its own pace.

Rated 5 out of 5 by from Great Fathers Day Gift Got this saw for my Dad on Fathers Day. He loves how light it is, and how easy it is to start. He says the Anti-Vibration handle helps keep his elbows from hurting after a day in the tree line. -Phenomenal unit for the price!

Rated 1 out of 5 by from Garbage straight from the dealer I was having a fence put in and needed to cut down 2 small trees.The dealer told me it was all serviced and ready for use out the door. The chain was binding on the very first cut, this thing couldn't make it through 6 inches of wood. I tried to adjust the tension but the tension screw was already stripped, the chain was hanging off the blade and couldn't be tightened any farther.I will never buy Stihl again, my leaf blower is ok but this thing is unforgivable.

Rated 5 out of 5 by from Great light weight saw for smaller jobs. Saw is a little under powered but works great for the small jobs ie limbing and small logs. Great value.
