Overview
A replacement chain engineered to match the original specifications of DEWALT DCCS677Y1 Chainsaw chainsaws. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.
Key specifications
- Bar length: 20”
Compatibility
Fits DEWALT DCCS677Y1 Chainsaw as a direct replacement for the factory chain. Check your owner’s manual or the existing chain’s markings to verify pitch, gauge, and drive link count before ordering.
Installation notes
Power down the saw and disconnect the battery or spark plug lead. Remove the side cover and release bar tension. Take the old chain off the bar and sprocket, then thread the new chain into the bar groove, confirming the cutting edges face forward on the top rail. Set the tension so the chain pulls freely without sagging away from the bar, and do a brief test run to verify everything tracks correctly.
Common questions
Q: Will this 20 inch chainsaw 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’s the correct replacement type for that saw. It’s still a good idea to confirm the chain specs stamped on your current bar or listed in your manual so the pitch, gauge, and drive link count match your setup exactly.
Q: I’m replacing the chain on my DEWALT DCCS677Y1 for the first time—do I need to do anything special after installing this 20 inch chain?
After installation, make sure the chain sits properly in the bar groove and around the drive sprocket, then adjust the tension so the chain snaps back into place when lightly pulled from the bar. Run the saw briefly, recheck tension after the chain warms up, and keep the bar oil reservoir filled since a new chain can loosen slightly during the first few cuts.
Q: How often should I sharpen and maintain this 20 inch chain on my DCCS677Y1 to keep it cutting well?
Sharpen it whenever you notice it pulling to one side, producing fine sawdust instead of chips, or requiring extra pressure to cut. Also keep the chain properly tensioned, clean debris from the bar groove and oil ports, and inspect the cutters regularly since a sharp, well-oiled chain will cut faster and reduce strain on the saw.
