What this is
Two replacement chains for 10” saws that take 3/8” low-profile, .050” gauge chain with 40 drive links. That covers Craftsman’s V20 CMCCS610 and CMECSP610, BLACK+DECKER’s BECSP601, the Worx WG309, Sun Joe’s SWJ803E and SWJ807E, Makita’s XAU02ZB, the DeWalt DXGP210, several Remington pole saws and the Scotts PS45010S. The full list with each maker’s own chain part is in the table below.
The 10-inch mix-up: .050” or .043”
Most 10” chains of this pitch have 40 drive links, so the link count alone won’t tell you which one you need. The gauge will:
| Gauge | Saws |
|---|---|
| .050” | Craftsman CMCCS610 / CMECSP610, BLACK+DECKER BECSP601, Worx WG309, Sun Joe SWJ803E / SWJ807E, Makita XAU02ZB, Remington and Scotts pole saws — this chain |
| .043” | Worx WG322 / WG323, Makita XCU06, BLACK+DECKER LCS1020, Ryobi P546 / P547 (our chain for those) |
Even the part catalogs don’t always agree. Craftsman’s own chain for the CMCCS610 and CMECSP610, CMZCSC10, is .050”, but Oregon files those two saws under a .043” chain. BLACK+DECKER’s PP610 manual names RC1000, which Oregon cross-references to .043”, while Oregon’s entry for the PP610 says .050”. The gauge is stamped on the tail of most bars; check it if you’re unsure.
Fitting it
The WG309 has a tool-free tensioning knob with a built-in ratchet. On the Sun Joe saws, tension is set with an adjusting screw. Whatever the saw, use the bar and chain combinations its manual lists.
