Overview

Key specifications
- Bar length: 12”
- Includes: guide bar and chain (matched set)
- Material: hardened alloy bar with chrome-plated chain
Compatibility
Engineered to fit DEWALT DCCS620B 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 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 12-inch guide bar and chain combo fit my DEWALT DCCS620B cordless chainsaw without any modifications?
Yes, this combo is made for the DEWALT DCCS620B and matches the 12-inch bar size that saw uses. As long as your saw is the DCCS620B model, the bar and chain should install in the original mounting location with the standard tensioning setup.
Q: Does this 12-inch bar and chain come ready to install on a DCCS620B, and do I need to sharpen or adjust anything first?
You can install it right out of the package, but you should still check chain tension before running the saw. After the first few cuts, recheck the tension because a new chain can stretch slightly, and make sure the bar oil reservoir is full so the new bar and chain are properly lubricated.
Q: How do I know when this DEWALT DCCS620B 12-inch bar and chain combo needs maintenance or replacement?
If the chain starts pulling to one side, produces fine dust instead of chips, or needs frequent tightening, it likely needs sharpening or inspection. Also check the guide bar groove and tip for uneven wear, and keep the oil port clean so the bar and chain continue to oil correctly.
