13 Adjusting the thread tensioning plate
Preparing the adjustment using the Schmidt MST-2000
Use screw clamps to attach a plain sheet of metal (e.g. 6 mm aluminum)
to the tabletop on the left-hand side of the machine.
Set up the thread scale with its suction cup base on the metal plate in such
a way that the sewing thread - coming from the thread lever - lines up with
thread guides both horizontally and vertically.
Important
Use a Serafil 30 black thread to set the thread tensioning plate.
cw = turn clockwise
ccw = turn counterclockwise
