Greenworks Gen2 Chainsaw 12" Replacement Chain Set

Greenworks Gen2 12” replacement chain fitment overview

This 2-piece 12-inch replacement chain set is made for specific Greenworks Gen2 chainsaws: ‎CS40B210 and ‎CS40B00. It is intended for Gen2 models that use a 0.043” gauge chain, so it is important to confirm your saw’s model and chain specs before ordering.

The package includes 2 pcs 12-inch chain, giving you a spare chain to keep on hand for routine maintenance, cleanup work, or fast swap-outs when your current chain becomes dull.

Will this chain fit your saw?

This chain set is a fit for:

• Greenworks ‎CS40B210
• Greenworks ‎CS40B00

Important fitment note:

• Specifically for Gen2 models
• Specifically for 0.043” gauge setups
• 12” bar length

Before purchase, verify all of the following on your chainsaw or current chain:

• Bar length: 12”
• Gauge: 0.043”
• Pitch: match your current chain/bar specification
• Drive-link count: match your current chain exactly

Bar length alone is not enough to guarantee fit. Two 12-inch chains can still differ in gauge, pitch, or drive-link count, and any mismatch can cause poor cutting performance or prevent proper installation. The safest way to confirm fitment is to check your owner’s manual, the markings on the guide bar, or the specifications printed on the chain you are replacing.

If you have a Greenworks ‎CS40B210 or ‎CS40B00 Gen2 saw and it uses a 0.043” gauge 12-inch chain, this set is the correct application according to the original listing. If your saw is a different Greenworks model, a non-Gen2 version, or uses a different gauge, do not assume this chain will fit.

Replacing the chain

Use basic chain-saw safety whenever changing a chain. Gloves are strongly recommended because cutter edges can be sharp even on a dull chain.

1. Power the saw off completely and remove the battery before doing any service.
2. Loosen and remove the side cover, then release chain tension so the old chain can come off the bar and drive sprocket.
3. Install the new chain around the sprocket and along the guide bar groove, making sure the cutting edges face the correct direction on the top of the bar.
4. Reinstall the side cover and adjust chain tension until the chain sits snugly in the bar groove but can still be pulled around by hand.
5. Tighten the cover securely, then recheck tension before use.
6. After a short test cut, stop the saw and check tension again, since a new chain can settle in quickly.

If you are unsure about the correct chain direction or tension setting, consult your Greenworks manual for your exact saw model.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the saw, and helps reduce heat buildup.

• Keep the chain properly tensioned. A loose chain can derail, while an overly tight chain can wear the bar and drivetrain more quickly.
• Avoid contact with dirt, rocks, nails, or concrete. Even brief contact can dull cutters very quickly.
• Check chain oiling and bar condition regularly. Good lubrication helps reduce friction and extends the life of both the chain and the guide bar.

Rotating between the 2 included chains can also make maintenance easier: use one while sharpening the other.
