Opuladuo 8" Replacement Chain for Dewalt DCCS623B DCCS623L1 Chainsaw

This 8” replacement chain is intended for select DeWalt compact saw applications that use an 8-inch bar. Based on the original listing, it is specifically matched to the DeWalt DCPS620, DCPS620B, and DCPS620M1 pole saw, and this product page also identifies it for the DeWalt DCCS623B and DCCS623L1 chainsaw.

Will this chain fit your saw?

The quickest way to confirm fit is to match your current chain and bar details, not just the brand name. Start with the bar length: this chain is for an 8” bar. If your saw uses a different bar length, this chain is not the right choice.

Next, verify the chain specifications printed on the guide bar or in your saw’s manual:

• Pitch
• Gauge
• Drive-link count

All three must match your original chain for proper fit and safe operation. Bar length alone is not enough, because many 8-inch saws and pole saws can use different chain setups.

Compatible models and applications named in the listing:

• DeWalt DCCS623B
• DeWalt DCCS623L1
• DeWalt DCPS620
• DeWalt DCPS620B
• DeWalt DCPS620M1

If your saw is one of the models above, this chain is intended for that platform. If you are still unsure, remove the existing chain and compare its markings and link count to the replacement before installing it.

Replacing the chain

Always replace the chain with the battery removed and wear gloves while handling the cutters.

1. Remove the battery and let the saw cool completely.
2. Loosen the side cover and back off the chain tension so the old chain can be lifted off the bar and drive sprocket.
3. Clean sawdust and oil buildup from the bar groove, sprocket area, and side cover before installing the new chain.
4. Fit the new chain around the drive sprocket and along the bar, making sure the cutter direction matches the normal cutting rotation shown on the saw or old chain.
5. Reinstall the side cover, then adjust chain tension until the chain sits snugly on the bar but can still be pulled around by hand with a gloved hand.
6. Reinstall the battery and run the saw briefly, then recheck tension. A new chain will often stretch slightly during the first few cuts.

If the chain will not tension correctly, do not force it. Recheck bar length, drive-link count, and whether the chain is seated fully in the bar groove.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the motor, and is safer to use than a dull one.

• Keep chain oil topped up and make sure oil is reaching the bar and chain. Poor lubrication causes rapid wear and dulling.
• Avoid cutting into dirt, sand, or wood lying on the ground. Even brief contact with abrasive material can dull a chain quickly.
• Touch up the cutters early instead of waiting until the chain is badly dull. If the saw starts producing fine dust instead of chips, pulling to one side, or needing extra pressure, it is time for maintenance.

It is also a good idea to inspect chain tension often, especially during the first use of a new chain.

FAQ

Will this fit any 8-inch DeWalt saw?
Not automatically. Even if the bar is 8 inches, the pitch, gauge, and drive-link count still need to match. Use the bar markings or owner’s manual to confirm.

Can this chain be used on the DeWalt pole saw models from the listing?
Yes. The original listing names the DeWalt DCPS620, DCPS620B, and DCPS620M1 pole saw as compatible applications.

Why does a new chain loosen after a few cuts?
That is normal. New chains seat in and stretch slightly at first. Stop the saw, remove the battery, and retension the chain before continuing.

How tight should the chain be?
It should sit firmly in the bar groove without sagging underneath the bar, while still moving freely by hand with gloves on. Overtightening can cause premature wear to the bar, chain, and saw.
