18" Replacement Chain for Black+Decker CS1518 Chainsaw

Fitment overview

This 18-inch replacement chain is intended for the Black+Decker CS1518 chainsaw. If you have a CS1518 and your saw is set up with an 18-inch bar, this is the model match named in the original listing.

The package includes 2Pcs 18-Inch Chain, which is useful if you want a spare ready to swap in when the first chain gets dull.

Will this chain fit your saw?

The listed fitment is:

• 18 Inch Chainsaw Replacement Chain for Black+Decker CS1518 Chainsaw
• Black+Decker CS1518

The most important first check is bar length. This chain is sold as an 18-inch replacement chain, so it is meant for a saw using an 18-inch bar.

To fully confirm chain fit, you should also verify these three chain specs on your current bar or chain:

• Pitch
• Gauge
• Drive-link count

Those three measurements must match your saw’s setup, not just the bar length. On many chainsaws, the bar has these specs stamped or printed near the mounting end. You can also check the old chain packaging or owner’s manual if you still have it.

A quick way to confirm fit is:

• Make sure your saw model is Black+Decker CS1518
• Confirm the bar installed on the saw is 18 inches
• Compare the pitch, gauge, and drive-link count from your current chain/bar to the replacement you are ordering

If your saw is a different Black+Decker model, or if the bar has been changed from the original size, do not assume an 18-inch chain will fit just because the brand matches. Chains are not universal across all 18-inch saws.

Replacing the chain

Before replacing the chain, unplug the saw and wear gloves. Chains are sharp even when dull enough to need replacement.

1. Disconnect power and let the saw cool completely.
2. Loosen the side cover and back off the chain tension so the old chain can be removed from the bar and sprocket.
3. Clean sawdust and debris from the bar groove, side cover area, and drive sprocket area before installing the new chain.
4. Fit the new chain around the sprocket and along the bar, making sure the cutter direction matches the normal forward cutting direction on the top of the bar.
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. After tightening everything, recheck tension after the first few cuts, because a new chain can seat in and loosen slightly.

If you are unsure about correct cutter direction or proper tension, compare carefully to the chain you removed before disposal.

Keeping it sharp

A sharp chain cuts faster, throws larger wood chips, and puts less strain on the motor. If the saw starts making fine dust instead of chips, pulls to one side, or requires extra pressure to cut, it is time to sharpen or change the chain.

A few practical habits help chain life:

• Keep the chain properly tensioned; a loose chain wears faster and can derail
• Avoid touching dirt, rocks, fencing, or the ground while cutting
• Rotate between the 2 included 18-inch chains so you can sharpen one while using the other

It also helps to inspect the bar regularly for burrs, uneven wear, or a packed groove, since bar condition affects how well any new chain performs.

FAQ

Does this fit any Black+Decker 18-inch chainsaw?

No. The listing specifically identifies the Black+Decker CS1518 chainsaw. Even among 18-inch saws, pitch, gauge, and drive-link count can differ.

How many chains are included?

The package includes 2Pcs 18-Inch Chain.

Do I only need to match the 18-inch bar length?

No. Bar length is only the starting point. You should also confirm pitch, gauge, and drive-link count from your current bar or chain to ensure proper fit and safe operation.

When should I replace instead of sharpen?

Replace the chain when cutters are badly worn, damaged, or difficult to sharpen evenly, or when the chain no longer cuts well after proper sharpening and tensioning.
