Bobbin Winding Issues
The bobbin is not filling evenly, either too
much thread on the top or bottom
The bobbin winder stops before the bobbin is
full or after the bobbin has too much thread
Locate the bobbin tensioner (D) and loosen the screw
(E) just under the tensioner on the front of the machine.
Move the tensioner down if the bobbin is filling with too
much thread on the top. Move the tensioner up if there is
too much thread on the bottom. Tighten the screw after
correct positioning.
There is a bobbin stop (F) right next to the bobbin winder.
Simply loosen the screw found on top of the black lobe and
turn the stop to change the thread fill level.
The closer the lobe is to the bobbin the less it will fill, the
farther away the more it will fill.
