Question about Euro-Pro 534DX Mechanical Sewing Machine
Usually is the lower knife that gets dull.
Resharpen or replace the lower knife.
when replacing the lower knife, the top of the knife must be flashed with the needle hole plate (teeth plate).
With the top knife at its lower dead center (lower position),
Undo the top knife holding screw, and adjust the knife to overlap the lower knife about 1mm.(inside)
Tight the top knife.
Undo the screw for the side movent for the lower knife, and the spring should push the lower knife against the top knife.
Tight the the screw for the side movement.
Put a piece of thread between the knives and turn the handwheel by hand, in the sewing direction until the top knife is at the lowest position.
If the thread is clearly cut, then the knives are cutting properly.
If the thread is pushed towards you, then one of the knives or both of them need resharpenig or replacement.
