Lower And Upper Blade/Knife Janome Domestic Overlock Sewing Machine

Parts number:788013009+788127007

The Upper and Lower Knife set you are referring to is a replacement part that is compatible with several Janome serger/overlock machines including the 8002DX, 9102D, 9200D, 9300DX, DM234, and 204D. The set is designed to cut the fabric edge as it is fed through the machine, and over time, the knives can become dull or damaged, which can cause problems with the machine's performance.

If you need to replace the Upper and Lower Knife set on your Janome serger/overlock machine, you can purchase a compatible set and install it following the manufacturer's instructions. Before starting, make sure to turn off the machine and unplug it from the power source. Then remove the old knives and replace them with the new set. Be sure to use the correct type of knife set for your machine to ensure optimal performance.
