  The R36XCHS10 Is a 12" Saw, Not a 10" Saw

  The model number is the biggest cause of wrong chain orders on this saw. R36XCHS10 has a 12" (304mm) bar and takes a 45 drive link chain. The "10" is a Ryobi series number, not the bar length.

  There is a separate Ryobi saw with a genuinely 10" bar — the R36CHS10, with no "X" in the model code. That one takes a different drive link count. Check the code on the saw body, not the box.

  Ryobi R36XCHS10 Chain Questions

  What size chain does a Ryobi R36XCHS10 take?

  3/8" LP pitch, .043" (1.1mm) gauge, 45 drive links, on its 12" bar.

  Is the R36XCHS10 a 10 inch or 12 inch chainsaw?

  12 inch (304mm). The "10" in the model number is a series code, not the bar length.

  How many drive links is an R36XCHS10 chain?

  45 drive links. If you're unsure, 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 R36XCHS10 chain?

  A 4.0mm round file suits this 3/8" LP chain.

  Will this chain fit other Ryobi saws?

  Possibly, but please use our Search by Chainsaw tool to find your specific saw chain with no doubt.

  Is this a genuine Ryobi chain?

  No — it's an Alpine Chain Co. chain manufactured to fit the R36XCHS10. Same pitch, gauge and drive link count, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Ryobi R36XCHS10, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
