Opuladuo 2PC 10 Inch Pole Saw Chain for RYOBI RY40506BTL / RY40560 / RYPRN33

This Opuladuo 2-piece 10-inch pole saw chain set is intended for a range of RYOBI pole saw and compact chainsaw models that use a 10-inch bar, including RY40506BTL, RY40560, and RYPRN33. If you want a spare chain on hand or need to replace a dull or damaged one, this listing is aimed at those RYOBI platforms called out below.

Will this chain fit your saw?

The first check is simple: your saw must use a 10-inch bar. This product is described as a 10-inch replacement chain, so bar length needs to match.

After that, the most reliable way to confirm fit is to compare the chain specifications printed on your current bar, chain, or owner’s manual:

• Bar length: 10”
• Pitch: match your original chain
• Gauge: match your original chain
• Drive-link count: match your original chain

Those last three specs matter just as much as bar length. A 10-inch chain is not automatically universal, even within the same brand. If the pitch, gauge, or drive-link count differs from your original setup, the chain may not tension correctly or run safely.

According to the original listing, this chain is for these RYOBI models and related part/model references:

For this product page specifically, that includes fitment references for:

If your saw’s exact model tag matches one of the models above and it uses a 10-inch bar, you’re on the right track. If your saw has had the bar replaced at some point, verify the chain specs on the bar rather than relying only on the powerhead model number.

Replacing the chain

Before starting, disconnect power. On battery models, remove the battery. On corded or gas units, make sure the saw cannot accidentally start.

1. Let the saw cool and wear gloves before handling the old chain.
2. Loosen and remove the side cover so the bar and chain can come free.
3. Lift off the old chain and inspect the bar groove and drive sprocket area for packed sawdust or damage.
4. Install the new chain around the sprocket and along the bar, making sure the cutter direction matches the rotation shown on the saw or old chain.
5. Refit the side cover, then adjust chain tension so the chain sits snugly in the bar groove but can still be pulled around by hand with a gloved hand.
6. Tighten the cover hardware securely, then recheck tension after the first few cuts.

A new chain will often stretch slightly during initial use, so it’s normal to make a small tension adjustment early on.

Keeping it sharp

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

• Keep the chain properly tensioned. A loose chain can derail; an overtight chain causes extra wear on the bar and drive components.
• Avoid cutting into dirt, fencing, or wood lying on the ground, since contamination dulls cutters very quickly.
• Check chain oil flow and keep the bar groove clean so the chain runs cooler and lasts longer.

If cutting performance drops, the saw starts producing fine dust instead of chips, or you have to force the cut, the chain likely needs sharpening or replacement.

FAQ

Does this package include one chain or two?

The original listing states: 2Pcs 10-Inch Chain. That means you’re getting two 10-inch replacement chains in the package.

Will this fit any 10-inch saw?

No. A 10-inch bar length alone is not enough to guarantee fit. Your saw also needs the same pitch, gauge, and drive-link count as the original chain, and the listing’s intended fitment is for the RYOBI models named above.
