Replacing the knife
Since the lower knife blade and the chain-off thread cutter blade are made of special carbide material, it is not normally
necessary to replace them. However, they should be replaced when the blade edge is damaged.
For replacement of the lower knife blade, upper knife blade and the chain-off thread cutter blade, consult the distributor
where you have purchased your sewing machine.
