6 Inch Craftsman CMCCS320 CMCCSL621 Pruning Chainsaw Chain

Fitment Guide

This 6 inch replacement pruning chainsaw chain is made for select Craftsman compact pruning saws that use a 6-inch bar. Based on the original listing, it fits Craftsman CMCCS320D1, CMCCS320B, CMCCS320C1, CMCCS320, CMCCSL621, and CMCCSL621D1 pruning saw models.

The package includes 2 pcs 6-inch chain, which is handy if you want a spare ready when the first chain needs sharpening or replacement.

Will this chain fit your saw?

The quickest way to confirm fitment is to match your saw’s model number first, then verify the chain specs printed on the bar, in the owner’s manual, or on the original chain packaging.

This chain is listed for these Craftsman models:

• CMCCS320
• CMCCS320B
• CMCCS320C1
• CMCCS320D1
• CMCCSL621
• CMCCSL621D1

It is described in the source listing as a 6-inch chain for these pruning saws, so the first check is simple:

• Your saw should be one of the compatible Craftsman models above
• Your bar length should be 6 inches

After that, confirm the three chain-size details that always matter on any chainsaw chain:

• Pitch
• Gauge
• Drive-link count

Those specs must match your bar and sprocket setup exactly. Since the original listing only confirms the 6-inch bar fitment and the compatible model numbers, the safest approach is to compare your current chain or your saw manual before ordering if you want to double-check. Even on saws with the same bar length, chain specs must match exactly for proper fit and safe operation.

A good way to verify is to look for markings on:

• The guide bar
• The old chain
• The saw’s manual
• The product label on your original replacement chain

If your saw is a Craftsman CMCCS320 series or CMCCSL621 series pruning saw listed above and uses the original 6-inch setup, this is the chain the listing identifies for that application.

Replacing the chain

Before replacing the chain, remove the battery and wear gloves. Even a dull chain can cut skin.

1. Remove the battery and make sure the saw cannot start accidentally.
2. Loosen or remove the side cover to access the bar and chain.
3. Take off the old chain and clean sawdust and oil buildup from the bar groove and sprocket area.
4. Install the new 6-inch chain around the sprocket and along the bar, making sure the cutting edges face the correct direction of travel.
5. Reinstall the side cover and adjust chain tension so 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 seat in and loosen slightly.

If the chain will not tension correctly, stop and confirm that the bar length and chain specs match your saw.

Keeping it sharp

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

• Avoid letting the chain contact dirt, rocks, fencing, or the ground. That is one of the fastest ways to dull cutters.
• Keep chain oil flowing properly if your saw uses bar-and-chain lubrication, and clean the bar groove regularly to reduce heat and wear.
• Touch up the chain or replace it when it starts pulling to one side, making fine dust instead of chips, or requiring extra pressure to cut.

Because this package includes 2 chains, many users rotate them: one on the saw, one sharpened and ready.
