What this is
Two replacement chains in an 18” size shared by several brands: 3/8” low-profile pitch, .050” gauge, 62 drive links. Oregon sells it as S62, and the saws in the table above all list a factory chain of this size.
Oregon CS1500 owners: remove the sharpening stone
The CS1500 comes with Oregon’s PowerSharp chain and a built-in sharpening stone. Oregon’s manual says the stone only works with PowerSharp chain and must be taken out when you fit any other chain, including this one. With the stone removed, sharpen this chain with a round file.
If you want to keep using the built-in sharpener, stay with Oregon’s own PowerSharp chain, 571037.
Check the bar length
Several of these saws are sold with more than one bar:
- Echo CS-370 / CS-400: Echo approves 14”, 16” and 18” bars. Only the 18” bar takes this chain.
- Harbor Freight Atlas: the 56937 is 18”; the 56938 is a 16” saw with a thinner .043” chain.
- Kobalt 80V KCS 180B-06: Oregon also lists a 16” bar option, which takes a 56-link chain.
- Craftsman S-series: the S185 is 18”; the S145 / S160 and S1450 / S1600 are 14” and 16” saws with shorter chains.
Count the drive links on your old chain: it should be 62.
Fitting it
The EGO CS1800 and Black+Decker CS1518 both have tool-free chain tensioning. EGO names AC1800 as the only replacement chain it recommends for the CS1800.
Same size, other saws
We list the same 18” size separately for Ryobi’s 18” saws (RY3818, RY40508 and others) and for the Husqvarna Power Axe 350i, which Husqvarna calls 3/8” mini.
