Overview
Pair a fresh 18” bar with a factory-sharp chain in one package. This aftermarket combo replaces the original equipment on your saw and arrives ready to mount, so you can get back to cutting without delay. It is a practical choice when your current bar is worn or your chain has seen too many sharpenings.
Key specifications
- Bar length: 18”
- Chain pitch: 3/8”
- Drive links: 62DL
- Includes: guide bar and chain (matched set)
- Material: hardened alloy bar with chrome-plated chain
Compatibility
This combo is built to work with EGO Power+ CS1800 and equivalent models that share the same bar-mount geometry. Confirm your saw’s model and year against the compatibility chart to ensure a proper fit, particularly if your saw has been updated with a different oiler setup.
Installation notes
Remove the side cover, slide the old bar off the studs, and clean any sawdust from the bar-mount area and oil port. Seat the new bar on the studs, loop the chain around the sprocket and bar nose, then hand-tighten the cover nuts. Adjust chain tension until the chain pulls away from the bar bottom about 1/8 inch and snaps back, then torque the nuts securely.
Common questions
Q: Will this 18-inch bar and chain combo fit my EGO Power+ CS1800 without any modifications?
Yes, this combo is made to match the EGO Power+ CS1800 and uses the correct 18-inch bar length with a 3/8 pitch chain. As long as your saw is the CS1800 model, it should install in place of the original bar and chain using the factory tensioning and cover hardware.
Q: Do I need to do anything special when installing this 18-inch guide bar and chain on my CS1800?
When installing it, make sure the chain is routed in the correct cutting direction on the top of the bar and seated properly in the bar groove and drive sprocket. After tensioning, the chain should pull away slightly from the bar but still snap back into place, and it’s a good idea to recheck tension after the first few cuts.
Q: Is the 3/8 pitch chain on this combo the right choice for normal firewood cutting and storm cleanup with the EGO CS1800?
Yes, the 3/8 pitch setup is the correct spec for this bar and chain combo for the CS1800, and it works well for general cutting tasks like trimming limbs, bucking small logs, and firewood prep. Keep the chain sharp and the bar oil reservoir full, because performance on battery chainsaws depends heavily on chain condition and proper lubrication.
