The MS 171 has some bumped up specs and added features, but the build is pretty much the same as the MS 170. Unlike the MS 170, it has tool-less fuel and oil caps with retainers and a side-access chain tensioner.
in., fuel capacity of 9.5 oz., chain oil capacity of 6.1 oz., and powerhead weight of 9.5 lbs. The MS 171 has a displacement of 1.94 cu. in., fuel capacity of 8.5 oz., chain oil capacity of 4.9 oz., and powerhead weight of 8.6 lbs. The MS 170 has a displacement of 1.80 cu. Let's compare them to get a better idea of what's going on. Looking at the MS 17X on the left side, you'll see that it has two gas versions, the MS 170 and MS 171.
You may notice that the third number is always between 0 and 3. This is why you'll see some 1XX and 2XX saws on both ends of the usage chart. These models may have different characteristics or designs that make them ideal for different use cases. We're assuming that it, combined with the first number, makes up a model number. The 017 became MS 170, 025 became MS 250, and so on. This changed around 2000 when they added MS to the beginning and moved the 0 to the end. For example, STIHL carried 017 and 025 model chainsaws. Model Numberīefore 2000, STIHL chainsaw model numbers began with a 0. We noticed that the first number is a good indicator of engine power, displacement, and fuel capacity (besides MSA and MSE models). We found this Chain Saw Comparison Chart on STIHL's website and grouped them together by the first number. There are a few more ideas out there, but none of them really stick. We've also heard that even and odd numbers or the generation of the saw somehow tie into it. Others say that the numbers align with the displacement of the saw, which seems to be the case some saws but doesn't hold up across the board.
#WHERE IS SERIAL NUMBER ON STIHL CHAINSAW MS 271 PROFESSIONAL#
Some suggest lower numbers are for homeowner saws and larger are for professional saws. Many people have made speculations about their meanings. The first part is easy to figure out, but the numbers are where things get tricky. MSA indicates that it's a battery chainsaw and MSE tells us that it's an electric model. The common part, MS, stands for Motorsäge which is German for chainsaw. Every STIHL chainsaw model name starts with MS, MSA, or MSE. Why are these ranked above some other models like the MS 271 or MS 391? That's what we're here to find out. However, if you look closely, you'll see some 1XX models, like the MS 150 T-CE and the MS 193 T, near the extensive use end. You would think the smaller the number, the less powerful the chainsaw, and vice-versa. STIHL hasn't released much information about the meaning of these model numbers, but they do have this chart ranking them from occasional to extensive use. It's a hot topic in many forums, and you'll find that it's very confusing. If you've ever bought, or thought about buying, a STIHL chainsaw, you've probably wondered what the letter and number abbreviations mean in the model names.
