Compatibility
This replacement chain works with DEWALT DCCS677Y1 Chainsaw. Verify your specific model number and existing chain dimensions before purchasing.
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 20 inch replacement chain fit my DEWALT DCCS677Y1, or do I need to match anything besides the bar length?
Yes, this chain is intended for the DEWALT DCCS677Y1 with a 20 inch bar, so it matches the saw’s specified bar length. It’s still smart to confirm the chain specs listed on your current bar or old chain, since pitch, gauge, and drive link count also need to match for proper fit and safe operation.
Q: Do I need any special steps to install this chain on my DCCS677Y1 after replacing the old one?
When installing it, make sure the cutting teeth on the top of the bar point forward toward the bar tip, then set chain tension so it sits snugly against the bar but can still be pulled by hand. After the first few cuts, recheck tension because a new chainsaw chain will usually stretch slightly during initial use.
Q: How often should I sharpen and oil this 20 inch chain on a DEWALT DCCS677Y1 to keep it cutting well?
Keep the chain oiled anytime the saw is running, and check the bar-and-chain oil level before each use to reduce heat and premature wear. Sharpen it whenever you notice fine sawdust instead of chips, the saw starts pulling to one side, or you need to push harder than normal through the cut.
