Why Chain Size for Stihl MS170 is Necessary
I’ve found that using the correct chain size on my Stihl MS170 is necessary because it keeps the saw running safely and smoothly. When the chain fits the bar properly, it cuts more efficiently and reduces the chance of kickback, slipping, or extra wear on the saw. A chain that is too long, too short, or the wrong pitch can make the saw harder to control and may even damage the bar or sprocket over time.
My experience has also shown me that the right chain size helps the engine perform better. The Stihl MS170 is a lightweight saw, so it works best with a chain that matches its power and bar length. If I use the wrong size, the saw can feel weak, bog down during cutting, or strain more than it should. That means less productivity and more frustration for me while working.
I also like knowing that the proper chain size helps me get cleaner, faster cuts with less effort. It saves time, reduces maintenance problems, and makes the whole cutting job safer and easier. For me, choosing the right chain size is not just a small detail—it’s one of the most important parts of keeping my Stihl MS170 dependable
My Buying Guides on Chain Size For Stihl Ms170
My Quick Take on the Right Chain Size
When I looked for the right chain size for my Stihl MS170, I learned that the most important thing is matching the chain to the bar length, pitch, and gauge. I found that the MS170 commonly uses a 3/8″ low profile chain with a .043″ gauge, but I always recommend checking the exact specs on my bar or owner’s manual before buying.
What I Check Before Buying
Before I choose a chain, I make sure I know these three things:
- Bar length – My MS170 may have a 12″, 14″, or 16″ bar.
- Pitch – I usually see 3/8″ low profile on this saw.
- Gauge – Commonly .043″, but I verify it first.
If any one of these is wrong, the chain will not fit properly or may not run safely.
How I Identify the Correct Chain
I usually check the guide bar itself because it often has the chain specifications stamped on it. If I cannot read the bar, I look at the old chain or the manual. I also count the drive links, because that number must match exactly.
Common Chain Sizes I’ve Seen for the MS170
In my experience, the MS170 often uses these sizes:
- 12-inch bar – usually 44 drive links
- 14-inch bar – usually 50 drive links
- 16-inch bar – usually 55 drive links
I still confirm the exact setup on my saw, because previous owners may have changed the bar or chain.
Why Chain Size Matters to Me
I learned that the wrong chain size can cause poor cutting, extra wear, or even safety issues. If the chain is too long, it will not tension correctly. If it is too short, it simply will not fit. Getting the right size helps my saw cut smoothly and last longer.
My Tips for Choosing the Best Chain
Here is what I personally look for:
- I choose a chain that matches my bar specs exactly.
- I prefer a reputable brand for better durability.
- I replace the chain if it is dull, stretched, or damaged.
- I keep a spare chain so I do not stop work unexpectedly.
My Final Advice
My best advice is to verify the bar length, pitch, gauge, and drive links before I buy anything. For the Stihl MS170, the most common setup is a 3/8″ low profile chain with a .043″ gauge, but I always double-check my saw’s markings to be sure. That way, I get the right fit and the best performance every time.
Final Thoughts
In my experience, choosing the right chain size for a Stihl MS170 comes down to matching the bar length, pitch, and gauge correctly. I always recommend checking the saw’s specifications before buying a replacement chain to make sure it fits and performs safely. When I use the proper chain size, my cuts are smoother, my saw runs better, and I avoid unnecessary wear.
