Overview
This aftermarket 20-inch replacement chain is designed to fit select Echo chainsaw models. When the factory chain wears out, loses its edge after multiple sharpenings, or stretches past the tensioner’s range, this chain gets you back to cutting without waiting for a dealer order. It’s built to OEM dimensions for a direct fit.
Key specifications
- Bar length: 20”
- Type: Semi-chisel (aftermarket replacement)
Compatibility
This chain is designed as a direct replacement for select Echo chainsaws. Double-check the pitch, gauge, and drive-link count on your existing bar stamp before purchasing. These three measurements must all match for safe operation.
Installation notes
On a longer 20-inch bar, proper tension is critical. Power down the saw and loosen the bar-retaining nuts. Push the bar toward the engine to create slack, then remove the old chain. Route the new chain around the bar nose and sprocket with cutters facing forward on top. Pull the bar back to take up slack, tighten the nuts, and fine-tune tension with the adjuster screw. The chain should lift slightly off the bar and snap back without drooping.
Common questions
Q: Will this 20” replacement saw chain fit my Echo CS-7310P-20G, or do I need to match anything besides the bar length?
Yes, this chain is intended for the Echo CS-7310P and CS-7310P-20G running a 20-inch bar. It’s still a good idea to confirm your current chain’s pitch, gauge, and drive link count match your bar and sprocket, since bar length alone doesn’t guarantee the correct fit.
Q: Can I install this replacement chain myself on my Echo CS-7310P, and how tight should I set it?
Yes, if you’re familiar with basic chainsaw maintenance, installation is straightforward: make sure the cutters face forward on the top of the bar, seat the chain fully in the bar groove, and then set tension so the chain snaps back into place when pulled slightly away from the bar. After a short test run, recheck the tension because a new chain can loosen slightly as it seats.
Q: What’s the best way to maintain this 20” saw chain so it cuts well on my CS-7310P?
Keep it properly tensioned, make sure the bar oil reservoir stays full, and clean the bar groove and oil holes regularly so the chain gets adequate lubrication. Touch up the cutters with the correct file size as soon as you notice slower cutting or fine sawdust, because a sharp chain runs cooler and reduces wear on the bar and clutch.
