Overview
Available as a 2-pack, this chain is a direct replacement for Greenworks CS40B00 models. Keeping a spare chain on hand means less downtime during jobs, and swapping a dull chain takes just minutes.
Key specifications
- Bar length: 12”
- Quantity: 2 chains per pack
Compatibility
Fits Greenworks CS40B00 as a direct replacement for the factory chain. 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 2-pack 12-inch chain fit my Greenworks CS40B00, or do I need to match anything besides the bar length?
Yes, this chain is made for a 12-inch setup and is listed as compatible with the Greenworks CS40B00. Besides bar length, it’s always smart to confirm your saw’s chain specifications from the bar stamp or manual so the pitch, gauge, and drive link count match your original chain.
Q: How do I install one of these replacement chains on my Greenworks CS40B00 and know if the tension is correct?
After loosening the side cover, place the chain around the drive sprocket and along the 12-inch bar, making sure the cutter teeth on the top edge face forward. Tighten the tension so the chain sits snug in the bar groove but can still be pulled around by hand with gloves; after a few minutes of cutting, recheck it because a new chain can stretch slightly.
Q: Since this comes with 2 chains, how should I maintain them to get the best performance on my 12-inch Greenworks saw?
Rotate between the two chains so you can clean and sharpen one while using the other, which helps reduce wear on the bar and sprocket. Keep the chain properly oiled, touch up the cutters before they get very dull, and inspect the drive links regularly for damage if you’ve cut dirty or storm-fallen wood.
