Compatibility
Engineered to fit EGO Power+ CS1800 saws and other models sharing the same bar-mount pattern. Always double-check your saw’s model number against the full compatibility list before ordering, since mount studs and oiler holes can vary between production years.
Installation notes
Loosen the bar-mount nuts and slide the old assembly off. Before fitting the new bar, clear packed sawdust from the oil passage and around the drive sprocket. Place the new bar onto the studs, route the chain around the bar groove and sprocket, then adjust tension to the point where you can pull the chain around by hand with light resistance. Snug the nuts in a cross pattern.
Common questions
Q: Will this 18-inch bar and chain combo fit my EGO Power+ CS1800 without any modifications?
Yes, this combo is made for the EGO Power+ CS1800 and matches the 18-inch bar length and 3/8 pitch that saw uses. As long as your saw is the CS1800 model, it should install in place of the original bar and chain with no modification needed.
Q: Does the chain come already matched to the 18-inch guide bar, or do I need to size or adjust it before installing it on my CS1800?
The chain is matched to the included 18-inch guide bar, so you should not need to shorten or resize it for a CS1800. After installation, just set the chain tension correctly, then recheck it after the first few cuts since a new chain can stretch slightly as it breaks in.
Q: What maintenance should I do on this bar and chain combo to help it last longer on my EGO Power+ CS1800?
Keep the chain properly tensioned, maintain bar oil flow, and sharpen the cutters regularly so the saw cuts without forcing. It also helps to clean the bar groove and oil holes periodically and flip the guide bar during service intervals to promote more even wear.
