Overview
Packaged as a set of 2, this chain is a direct replacement for Craftsman CMCCSL621 models. A sharp chain means less effort, cleaner cuts, and safer operation compared to pushing through wood with worn teeth.
Key specifications
- Bar length: 6”
- Quantity: 2 chains per pack
Compatibility
Engineered for direct compatibility with Craftsman CMCCSL621. Verify your specific model number and existing chain dimensions before purchasing.
Installation notes
Start by removing the battery or disconnecting the power cord. Pop off the sprocket cover, slide the old chain free, and thread the replacement onto the bar and drive sprocket. Keep the cutting teeth facing forward on the top of the bar. Set the tensioner until the chain has minimal sag, then do a quick hand rotation check before powering back up.
Common questions
Q: Will this 2PC 6 Inch Pruning Chainsaw Chain fit my Craftsman CMCCSL621 with the original 6-inch bar?
Yes, this chain is made for the Craftsman CMCCSL621 and matches the 6-inch bar size that comes on that pruning saw. As long as your saw still has the factory 6-inch bar, these replacement chains should fit properly.
Q: Do both chains in this 2-pack come ready to install on the CMCCSL621, and is there anything I should check when putting one on?
Yes, both chains are replacement chains for the 6-inch Craftsman CMCCSL621 setup and can be installed the same way as the original chain. When installing, make sure the cutting teeth face in the correct direction on the top of the bar and adjust the chain tension so it is snug but still moves freely by hand.
Q: How often should I sharpen or replace this 6-inch pruning chainsaw chain on my Craftsman CMCCSL621?
That depends on what you are cutting, but if the chain starts making fine dust instead of chips or you have to push the saw through branches, it likely needs sharpening. Keep the chain properly oiled and tensioned, and replace it if the cutters are badly worn, damaged, or no longer hold an edge well.
