Overview
This aftermarket replacement chain is designed to fit select Echo chainsaw models. It replaces the factory chain when the original becomes dull beyond resharpening, damaged, or stretched past the tensioner’s range. Keeping a spare chain on hand means less downtime during cutting season — swap in a fresh chain and keep working while you sharpen the old one on the bench.
Key specifications
- Pitch: 3/8
- Gauge: .050”
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select Echo chainsaw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Disconnect power before any chain work. Remove the bar cover to access the sprocket and bar. Take note of the cutter direction, then remove the old chain. Place the new chain in the bar groove with cutters oriented forward on the top rail. Loop it onto the drive sprocket, replace the cover, and turn the tension adjuster until the chain sits snug with minimal sag. Spin the chain by hand to confirm it moves freely.
Common questions
Q: Will this 24” 3/8 pitch chain fit my Echo CS-590 Timber Wolf with the stock 24-inch bar?
Yes, this chain is intended for the Echo CS-590 when you’re running a 24-inch setup and need a 3/8 pitch chain. Before installing, also confirm your bar’s gauge and required drive link count, since pitch alone is not enough to guarantee a correct fit.
Q: Do I need to do anything special when installing this chain on my Echo CS-590?
Make sure the cutter teeth are facing forward on the top of the bar, then set the chain tension so it sits snugly but still pulls around by hand with gloves on. After the first few cuts, recheck the tension because a new chain can stretch slightly as it seats in.
Q: How should I maintain this 24-inch saw chain to keep it cutting well on my CS-590?
Keep the chain properly sharpened, maintain correct chain tension, and make sure the bar oil system is delivering enough lubrication along the full 24-inch bar. It’s also a good idea to inspect the cutters and drive links regularly for damage, especially if you’ve hit dirt, rocks, or metal while cutting.
