8" replacement chain for Sun Joe and Greenworks.

If you need an 8-inch replacement chain for a compact electric chainsaw or pole saw, this chain is built around a common small-saw setup: 8-inch bar length, 3/8-inch pitch, .050-inch gauge, and 33 drive links. It is listed to fit specific Sun Joe, Greenworks, WEN, and Earthwise models, making it a straightforward option when your original chain is worn, dull, or damaged.

Will this chain fit your saw?

The best way to confirm fit is to match all four chain specs, not just the brand name:

• Bar length: 8 inches
• Pitch: 3/8 inch
• Gauge: .050 inch
• Drive links: 33

All four need to match your current chain and guide bar setup. Bar length alone is not enough, because many 8-inch saws use different chain configurations. You can usually confirm the specs by checking the markings on the guide bar, the owner’s manual, or the existing chain packaging if you still have it.

This chain is listed as compatible with these models:

Sun Joe

• SWJ800E
• SWJ806E
• SWJ802E
• SWJ801E

Greenworks

• 20672
• 20302
• PSPH40B00
• PSPH40B210
• PS40B210
• PS40B00
• 6.5 Amp Pole Saw
• PS24B210
• PS24B00
• PSPH24B210
• CS-80-XR
• 20352

WEN

• 4019
• 4021

Earthwise

• LPS40208
• CVPS41008

If your saw is one of the models above, this is the listed replacement chain. If your saw is a different model, verify the 8-inch, 3/8-inch pitch, .050-inch gauge, and 33-drive-link combination before ordering.

Replacing the chain

Before replacing the chain, unplug the saw or remove the battery. Wear gloves when handling the old or new chain, since even a dull chain can cut skin.

1. Make sure the saw is powered off, unplugged, or has the battery removed.
2. Loosen and remove the side cover to access the bar and chain.
3. Take off the old chain and clean sawdust and oil buildup from the bar groove and sprocket area.
4. Install the new chain onto the drive sprocket and around the guide bar, making sure the cutting edges face in the correct forward-cutting direction along the top of the bar.
5. Reinstall the side cover and adjust chain tension so the chain sits snugly in the bar groove but can still be pulled around by hand with a gloved hand.
6. Recheck tension after a short test run, since a new chain can stretch slightly during initial use.

A chain that is too loose can derail. A chain that is too tight can wear the bar, sprocket, and motor faster.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the saw, and is safer to use than a dull one.

• Keep the chain properly lubricated if your saw uses bar and chain oil. Low lubrication increases heat and dulls cutters quickly.
• Avoid cutting into dirt, rocks, or fencing. Even brief contact with abrasive material can dull a small chain fast.
• Check chain tension regularly, especially during the first few uses after installation. A loose chain wears unevenly and can cut poorly.

If the saw starts producing fine dust instead of chips, pulls to one side, or requires extra pressure to cut, it is usually time to sharpen or replace the chain.

FAQ

Does this chain fit every 8-inch chainsaw?

No. It fits saws that use this exact chain setup: 8-inch bar, 3/8-inch pitch, .050-inch gauge, and 33 drive links. Many 8-inch saws use different specs.

Can I use this on an 8-inch pole saw and an 8-inch handheld saw?

Yes, if the saw is one of the listed compatible models or if it uses the same chain specifications. The important part is matching pitch, gauge, drive-link count, and bar length.
