6 Inch Milwaukee 2527-20 M12 Fuel Replacement Chain

A 6-inch replacement chain for select pruning saws and loppers

This replacement chain is made for a 6-inch guide bar and is a direct fit for the Milwaukee 2527-20 M12 Fuel Pruning Saw when the saw uses the listed chain specs. It also fits certain 6-inch Craftsman and Remington saws listed below, making it a useful match if your original chain uses the same pitch, gauge, and drive-link count.

Will this chain fit your saw?

To confirm fitment, match all four chain specifications on your current chain, bar, or owner’s manual:

• Bar length: 6” (15 cm)
• Pitch: 3/8”
• Gauge: .043”
• Drive links: 28

If any one of those measurements is different, the chain may not fit correctly even if your saw looks similar. Chains are not matched by bar length alone.

This chain is listed as fitting these models and part numbers:

• Milwaukee 2527-20 M12 Fuel Pruning Saw
• Craftsman Cordless Lopper CMCCSL621D1 Chainsaw
• Remington Branch Wizard 111409-01
• Remington Branch Wizard RM0612P
• Remington Branch Wizard 41AZ01PG983
• Remington 11409-01 Pole Saw

A good habit is to compare the replacement chain to the old one before installation. If your existing chain is a 6-inch chain with 3/8” pitch, .043” gauge, and 28 drive links, this is the correct fit. If your old chain is missing or unreadable, check the markings on the guide bar or the specifications in the saw manual.

Replacing the chain

Replacing a small pruning-saw chain is straightforward, but safety matters. Follow your saw manufacturer’s instructions first, and use these general steps:

1. Turn the saw off and remove the battery or disconnect power before touching the chain.
2. Loosen or remove the side cover to release chain tension and access the bar and sprocket area.
3. Remove the old chain and inspect the guide bar groove, drive sprocket, and chain path for packed sawdust or damage.
4. Install the new chain around the sprocket and bar, making sure the cutting teeth face the correct cutting direction along the top of the bar.
5. Reinstall the side cover and adjust chain tension so the chain sits snugly in the bar groove while still moving freely by hand.
6. After installation, recheck tension after the first few cuts, since a new chain can settle in quickly.

Do not overtighten the chain. A chain that is too tight can wear the bar and drive components faster, while one that is too loose can derail.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the motor, and gives you better control in branches and small-diameter wood.

• Keep it clean. Resin, sap, and fine debris can make a chain feel dull even when the cutters are still in decent shape.
• Avoid dirt contact. Cutting into soil, dirty bark, or fence-line debris dulls a small chain very quickly.
• Check chain tension often. Proper tension helps the chain cut evenly and reduces unnecessary wear on the cutters and bar.

If you notice fine dust instead of chips, increased vibration, or the need to force the saw through wood, the chain likely needs sharpening or replacement.
