Bernina L850, L860, L890 Upper Knife

Replace the moving Bernina L800 series Upper blade when it has become blunt!
Replace the movable upper or lower blade yourself ?
There are always two blades in u lock machine these two blades work like scissors.

*The new color of the lower blade has turned black

Always unplug it first
1. Loosen the bolt and take the knife out of the knife holder
2. Insert the new blade into the blade holder and secure it again with the bolt.
3. Check that the cutting edges of the lower and upper blade overlap by approximately 0.5mm

* We always recommend replacing the lower and upper blade at the same time,
This is to prevent new blade from being damaged by the other blade.
