Compatibility
This replacement chain works with WORX WG309. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.
Installation notes
Turn off the chainsaw and remove its power source before servicing. Unscrew the bar cover, back off the tensioner, and pull the old chain free. Route the fresh chain around the clutch drum and into the bar groove, making sure the drive links seat properly. Tighten the tensioner until the chain snaps snugly against the underside of the bar but still slides freely, then run the saw briefly at idle to confirm smooth tracking.
Common questions
Q: Will this 3-pack of 10 inch chains fit my WORX WG309 chainsaw, or do I need to match anything besides the bar length?
Yes, these chains are made for the WORX WG309 and match the 10-inch bar with a 3/8 pitch. It’s still a good idea to confirm your current chain markings or owner’s manual so the pitch and overall chain size match your saw exactly before installation.
Q: I’m replacing the chain on my WORX WG309 for the first time—do these install the same way as the original chain?
Yes, installation is the same as the factory chain: unplug the saw, remove the side cover, loop the chain around the drive sprocket and bar, and make sure the cutter teeth on the top of the bar face forward. After reinstalling the cover, set the chain tension so it sits snug against the bar but can still be pulled around by hand with gloves on.
Q: How often should I sharpen or replace these 10 inch 3/8 chains on a WORX WG309?
Sharpen the chain whenever it starts producing fine sawdust instead of wood chips, pulls to one side, or requires extra pressure to cut. Replace the chain if the cutters are worn down, the chain stretches excessively, or you see damaged links that could affect safe operation.
