Overview
Sold as a 2-pack, this chain is a direct replacement for WORX WG309 models. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.

- Quantity: 2 chains per pack
Compatibility
This chain is designed to fit WORX WG309. Cross-reference your saw’s model number with the product listing to confirm compatibility.
Installation notes
Power down the saw and disconnect the battery or spark plug lead. Remove the side cover and release bar tension. Take the old chain off the bar and sprocket, then thread the new chain into the bar groove, confirming the cutting edges face forward on the top rail. Set the tension so the chain pulls freely without sagging away from the bar, and do a brief test run to verify everything tracks correctly.
Common questions
Q: Will this 2-pack of 10-inch chains fit my WORX WG309 chainsaw, and does the 3/8 pitch match the original setup?
Yes, these chains are intended for the WORX WG309 with a 10-inch bar and 3/8 pitch setup. As long as your saw still has the original 10-inch bar size, this is the correct pitch to match the sprocket and bar.
Q: I have a WORX WG309 and want to swap the chain myself. Do I need any special steps when installing these 10-inch replacement chains?
Before installing, unplug the saw and make sure the chain direction is correct, with the cutting edges facing forward on the top of the bar. After mounting, set the chain tension so it sits snug in the bar groove but can still be pulled around by hand, then recheck tension again after the first few minutes of use.
Q: How do I keep these 10-inch 3/8 chains cutting well on my WG309 without wearing them out too fast?
Keep the chain properly tensioned and make sure the bar oil reservoir is filled so the chain stays lubricated during cutting. It also helps to avoid hitting dirt or rocks, and to touch up the cutters with the correct file size as soon as you notice the chain starting to pull fine dust instead of chips.
