MS 171
A lightweight, fuel-efficient chainsaw with reduced-emission engine technology.

Product Description

  • 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.

Rated 3 out of 5 by from Bar bolt completely stripped out of the plastic threads Had this saw a little over 12 months a gift from my wife. complete with the Stihl carrying case. what a disappointment. i thought this saw would have been better quality.the few times i have got to used. it the chain would always get loose. I'd tighten it up and a couple cuts and it would be loose again. Only to find out the bar bolt had stripped out of the hunk of plastic it was threaded into .this could only happen after the warranty has expired.and the only fix is to replace the whole plastic housing that surrounds the saw. which is not cheap. you would thought Stihl would have a better design to attach the bar to the saw. Now I'm stuck with a door stop.

Rated 5 out of 5 by from Quality at a great price! This saw is so versatile and lightweight, easy to operate in tight spaces and ideal for home use.No issues whatsoever in handling and maintenance, chain is easy to replace.Fuel consumption is excellent for home use and the occasional trunk.Highly recommend.

Rated 1 out of 5 by from Do not buy. I got this chainsaw to start once. Do not waste your money. I got more of a workout trying to start this chainsaw then I did doing a full workout at crossfit. I wish I could get my money back. Cant even use this as a boat anchor. Maybe I can give it to my worst enemy.

Rated 1 out of 5 by from Fine when it starts This is the worst Stihl product I own. I love my problem free 026 saw, H45 hedge trimmer, and FS 56 weed trimmer. They start & run easily.This is OK when & if it starts. But I shouldn't have to fight a new saw to start.The guys at Ace laughed when I said that, because they'd heard it before.I've followed all of the instructions in the manual and am not new to chainsaws.This is a waste of money!

Rated 1 out of 5 by from Bought it and the carburetor is not working Can't use it, it will start but it won't stay running. Now I have to drive an hour and a half there to drop it off to be fixed, then go back home and do it all over again when I pick it up. Complete garbage, I was told these are the best in the business- what a joke

Rated 5 out of 5 by from Perfect for light use I was very unsure which chainsaw I wanted to purchase so when I went in to the store to purchase one I was just browsing at first. I was then asked by a sales clerk if I needed some help. I told him I do and I have narrowed my search down to two models and was wondering if I was in the right area. He said I was and he asked how much time will I be using the chainsaw for. I told him it is for home use only, if you will. I get cut up logs from friends and family who know I have a fire pit in my backyard in the city but they are too big to cut up by hand so I thought a chainsaw would be more appropriate. I also told him when I go camping that I will bring it too just to cut wood for a campfire. He recommended the MS171 as it will benefit my needs. I also asked if there was anything else he would recommend and he suggested that I get the premixed fuel and the bar oil. I said thank you very much. I took my chainsaw home and went into cutting up the wood even though it is hotter than Hades outside but at least I will be prepared for winter time and also I can put the wood on my log rack. I proceeded to cut up the mesquite that everyone has brought to me and well lets say it got the job done but dulled that chain right up. The chainsaw did exactly as it was supposed to but I don't think it was made for the hardwood Mesquite? Again the chainsaw performed well and It did not take me hours to complete my task, although I will either have to sharpen my chain or probably get the right type of stain for what I cut up.
