Overview
This aftermarket 8-inch replacement chain is designed to fit select DeWalt pole saw models. It serves as a drop-in replacement when the original chain becomes dull past the point of resharpening, develops a damaged cutter, or has stretched beyond the tensioner’s adjustment range. Having a spare on the shelf eliminates trips to the dealer mid-project.
Key specifications
- Bar length: 8”
- Drive links: 34DL
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select DeWalt pole saw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Always remove the battery or disconnect power before working on the chain. Loosen the bar cover, take out the old chain, and note which direction the cutters face. Thread the new chain around the bar nose and into the drive sprocket, keeping cutters pointed forward on top. Reattach the cover and tension the chain until it lifts slightly off the bar rail and snaps back. Test at low speed before cutting.
Common questions
Q: Will this Morocca 8” replacement chain fit my DeWalt DCPS620B pole saw, and does it match the 34 drive link .043 setup?
Yes, this chain is made to fit the DeWalt DCPS620, DCPS620B, DCPS620M1, DCCS623B, and DCCS623L1 models that use an 8-inch bar with 34 drive links and a .043 gauge. If your current chain is marked 34DL/.043 and your bar length is 8”, this is the correct replacement setup.
Q: How do I know if the chain is installed in the right direction on my DCCS623B?
When installed correctly, the cutting edges on the top of the bar should face forward toward the bar tip. After installing, set the chain tension so the chain sits snugly against the bar but can still be pulled around by hand with gloves; a loose chain can derail, while an overtightened one can wear the bar and motor faster.
Q: Do these 8” chains need sharpening often, and what maintenance helps them last longer on a DeWalt 20V MAX XR pole saw?
Sharpening frequency depends on what you’re cutting, but if the saw starts making fine dust instead of chips or you need to push harder through limbs, it’s time to touch up the cutters. Keep the chain properly tensioned, make sure the bar oil reservoir is filled, and clean the bar groove and drive area regularly to help both chains in the 2-pack last longer.
