6" Worx JawSaw Replacement Chain for Worx WG320 / WG320.9 / WG321 / WG307 / WG308

A simple replacement chain for select 6-inch Worx JawSaw and chainsaw models

This 6” replacement chain is made for specific Worx saws that use a 6-inch bar. Based on the original listing, it fits Worx WG320, WG320.9, WG321, WG307, and WG308 models, and the package includes 2 pcs 6-inch chain.

If your saw is one of those listed models and it uses a 6” bar, this is the intended replacement style. It is described as a 6 inch chain replacement for JawSaw and as a 6” chainsaw chain replacement for the Worx models named above.

Will this chain fit your saw?

The fastest way to confirm fit is to check your saw’s model number first. This replacement chain is listed for these exact Worx models:

• WG307
• WG308
• WG320
• WG320.9
• WG321

It is also specifically described as a 6 Inch Chain Replacement for JawSaw.

To verify fit more carefully, compare the chain and bar details on your current saw:

• Bar length: this chain is for a 6” bar
• Pitch: match the pitch marked in your saw manual or on the original chain packaging
• Gauge: the replacement chain must match the bar groove width
• Drive-link count: count the drive links on your old chain or confirm the exact spec in your owner’s manual

Those last three measurements matter just as much as bar length. A 6-inch chain is not automatically universal across all compact saws, so if your model tag is missing or your saw has had parts changed, confirm pitch, gauge, and drive-link count before ordering. If your saw is one of the listed Worx models above and still uses the original 6” setup, this is the correct fitment category from the listing.

Replacing the chain

Before starting, remove the battery or disconnect power so the saw cannot start accidentally. Wear gloves when handling the chain, even if it is dull.

1. Remove power from the saw and let the chain come to a complete stop.
2. Open the side cover or chain access area according to your Worx saw’s manual.
3. Loosen chain tension and remove the old chain from the bar and drive sprocket.
4. Install the new 6” chain, making sure the cutter direction matches the normal forward cutting direction shown on the saw or old chain.
5. Refit the bar and cover, then adjust chain tension so the chain sits in the bar groove but still moves freely by hand.
6. Recheck tension after a brief test run, since a new chain can settle in quickly.

If you are replacing a badly worn chain, it is smart to inspect the bar groove and drive area for packed debris or unusual wear before installing the new one.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the motor, and is safer to use than a dull one. For these compact 6-inch saws, chain condition makes a noticeable difference.

Helpful habits:

• Keep the chain out of dirt and soil, since even brief contact dulls cutters quickly.
• Check chain tension often, especially during the first few cuts with a new chain.
• Clean away sawdust and oil buildup around the bar and chain path so the chain can move freely.

If cutting performance drops, the saw starts producing fine dust instead of chips, or you need to force the tool through the wood, it is time to sharpen or replace the chain.

FAQ

Will this fit every 6-inch Worx saw?

No. A matching 6” bar length is important, but it is not the only fitment detail. This chain is listed for WG307, WG308, WG320, WG320.9, and WG321, so those are the models you should match first.

Does this include more than one chain?

Yes. The original listing states: Package Includes: 2Pcs 6-Inch Chain.

Can I install it if my old chain specs are unreadable?

Yes, if your saw is clearly labeled as WG307, WG308, WG320, WG320.9, or WG321 and it still uses the original 6” bar setup. If the saw has been modified or you are unsure, compare the old chain’s pitch, gauge, and drive-link count to avoid ordering the wrong replacement.
