If you're unsure which bar you have, the DL count is usually stamped on the bar itself, or count the drive links on your old chain. What file do I use on an MS 170 chain? A 4.0mm round file suits this 3/8" LP chain. Will this chain fit other Stihl saws? Possibly, but please use our Search by Chainsaw tool to find your specific saw chain with no doubt.
