Compatibility
Engineered to fit CRAFTSMAN CMCCS620M1 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
Remove the clutch cover and take off the spent bar and chain. Wipe down the bar pad and blow out the oiler port. Position the new bar, thread the chain onto the sprocket and around the bar groove making sure the cutters face forward on top. Use the tension screw to take up slack until the tie straps just lift off the bar rail, then secure the cover firmly.
Common questions
Q: Will this 12-inch saw chain and guide bar fit my CRAFTSMAN CMCCS620M1 cordless chainsaw without any modification?
Yes, this bar and chain combo is made to fit the CRAFTSMAN CMCCS620M1 with a 12-inch bar setup. If your saw is the CMCCS620M1 and you are replacing the original 12-inch bar and chain, it should install directly using the factory tensioning and mounting hardware.
Q: Do I need to replace both the bar and chain on my CMCCS620M1, or can I just use the chain from this combo?
You can replace both together if your current bar has rail wear, uneven groove wear, or nose sprocket issues, which is often the best way to restore cutting performance. If your existing 12-inch bar is still in good condition and matches the chain specs your saw requires, many users replace only the chain, but this combo is useful when both parts are worn.
Q: What should I check when installing this 12-inch guide bar and chain on a CRAFTSMAN CMCCS620M1?
Make sure the chain is routed in the correct cutting direction and seated fully in the bar groove and drive sprocket before tightening the side cover. After setting chain tension, add bar and chain oil, then recheck tension after the first few cuts since a new chain can stretch slightly during initial use.
