EDF3. Winding the bobbin thread
3.1 The method of winding
Insert the bobbin B into winder shaft, threading the
thread A to upper and lower holes of pin E, then to
thread tension disc F, draw the thread tip and wind
thread several circles around bobbin B, put the
winding lever D into bobbin B, then it can automatic
winding when sewing. (If only winding, not sewing,
please lift the presser foot.)
Please don't overfill the bobbin thread, otherwise the
thread will loosen down from the bobbin. The
optimum capacity of bobbin thread is fill about 80%
of bobbin outside diameter, and this can be adjusted
by screw D. After finish, thread can be cut by thread
cutter shown in Fig. 12. Wind the thread A several
circles around cutter C, draw the thread and the
thread is cut.
