Opuladuo 10-Inch Replacement Chain Fitment Guide

Fitting the chain onto the bar and sprocket

This Opuladuo replacement chain is intended for select 10-inch and pole-saw applications that use a 3/8-inch pitch, .050-inch gauge, and 40 drive links. Based on the original listing, it is presented as compatible with several popular pole saw and compact chainsaw models from WORX, Sun Joe, WEN, Remington, Makita, BLACK+DECKER, and Greenworks.

Will this chain fit your saw?

Measuring chain pitch, gauge and drive links

The most important fitment details for any replacement chain are:

  • Bar length: 10-inch applications are referenced in the listing, though the known specs provided here also note an 8-inch bar length
  • Pitch: 3/8
  • Gauge: .050
  • Drive link count: 40

To confirm fit, check your current chain or your guide bar markings for these exact specs. A chain must match all key dimensions used by your saw setup: pitch, gauge, and drive-link count. Bar length alone is not enough to guarantee compatibility.

The original listing names the following saws and part-numbered models:

  • WORX WG309 10″ Electric Pole Saw
  • Sun Joe SWJ803E SWJ807E 10-inch Pole Chain Saw
  • WEN 40421 40421BT inch Pole Chain Saw
  • Remington RM8EPS Ranger II 2-in-1 Pole Saw
  • Makita XAU02ZB 10″ Pole Saw
  • BLACK+DECKER PP610 BECSP601 Pole Chainsaw
  • Greenworks 2000102 20362 CS24B210 CS24B00 24V 10-Inch Chainsaw

A quick note on the specs: the source material mixes a product title referring to a 10-inch replacement chain with a known-spec line stating 8-inch bar length. Because of that conflict, the safest way to verify fit is not by title alone, but by matching your existing chain’s 3/8 pitch, .050 gauge, and 40 drive links against your saw’s current setup.

If your existing chain does not match those dimensions exactly, this is not the right replacement.

Replacing the chain

Before starting, unplug the saw or remove the battery.

  1. Let the saw cool completely and wear gloves before handling the old chain.
  2. Loosen the side cover and release chain tension so the old chain can be removed from the bar and drive sprocket.
  3. Clean debris from the bar groove, sprocket area, and oiling port before installing the new chain.
  4. Fit the new chain around the drive sprocket and along the guide bar, making sure the cutter direction matches the saw’s normal cutting rotation.
  5. Reinstall the side cover and adjust chain tension until the chain sits snugly on the bar but can still be pulled around by hand with a gloved hand.
  6. Recheck tension after a short test run, since a new chain can stretch slightly during initial use.

If you are unsure about proper cutter direction or tension, refer to your saw’s owner’s manual before operating.

Keeping it sharp

Sharpening a chainsaw chain cutter

A replacement chain lasts longer and cuts better when the saw is set up correctly.

  • Keep the chain properly tensioned. A chain that is too loose can derail, while one that is too tight can wear the bar, sprocket, and motor more quickly.
  • Maintain chain lubrication. Pole saw and compact chainsaw chains depend on good bar oil flow to reduce heat and premature wear.
  • Avoid hitting soil, rocks, nails, or fencing. Even a brief contact with abrasive material can dull a sharp chain fast.

If cutting performance drops and you find yourself forcing the saw through wood, inspect the cutters and depth gauges before continuing.

FAQ

Does this chain fit every 10-inch chainsaw or pole saw?

No. Even among 10-inch saws, chain specs can vary. Confirm 3/8 pitch, .050 gauge, and 40 drive links before ordering.

Because bar length alone does not determine chain fit. The correct replacement chain must match the exact drive-link count as well as pitch and gauge.
