Overview
Available as a 2-pack, this chain is a direct replacement for EGO CS1800 / CS1803 / CS1804 18-Inch Chainsaw models. Keeping a spare chain on hand means less downtime during jobs, and swapping a dull chain takes just minutes.
Key specifications
- Bar length: 18”
- Quantity: 2 chains per pack
Compatibility
Fits EGO CS1800 / CS1803 / CS1804 18-Inch Chainsaw 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
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 2-pack 18-inch chain fit my EGO CS1803, or is it only for the CS1800?
Yes, this replacement chain is made for the EGO CS1800, CS1803, and CS1804 18-inch chainsaws. If your saw uses the stock 18-inch bar, these chains are the correct fit for those listed models.
Q: Do I need to replace the bar too when installing one of these chains on my EGO CS1804?
Not necessarily—if your 18-inch bar is still straight, the groove is not excessively worn, and the nose sprocket turns freely, you can usually install just the new chain. It’s also a good idea to clean the bar groove and oil holes before fitting the new chain so it runs smoothly and gets proper lubrication.
Q: What’s the correct way to tension this replacement chain on an EGO CS1800 after installation?
After installing the chain, tighten it so the drive links stay engaged in the bar groove while the chain can still be pulled around by hand with a gloved hand. Run the saw briefly, let it cool, and recheck the tension, since a new chain can stretch slightly during the first few cuts.
