Install the bobbin B to the winder shaft. Thread A should
pass through the center of the two tension discs E, then
wind the tip of the thread a few turns around the bobbin B.
Open the stop latch thumb lever D vertically so that the
spring plate C is pressing upon the bobbin B. Thus when
sewing, the machine is able to wind automatically. (The
presser foot must be lifted when winding without sewing.)
The bobbin should not be overfilled.The thread capacity is
an optimum 80% of the outside diameter. The thread
capacity can be adjusted by spring tension plate adjusting
screw H.
When the bobbin is full, the bobbin thread could be cut by
trimming blade as shown in the Fig. Wind the bobbin
thread F two turns around the blade G, then pull it with a
sudden force. Thus the trimming is finished.
When threading the needle thread, the needle bar should be
lifted to its highest position. Lift the presser foot, open the
roller foot, and then thread the tip from the spool stand in
the following numerical order.
1. Pass through the two holes of the upper thread guide 1;
2. To left pass through the tension adjusting set plate right
thread guide hole, then ip through between the small
tension plate 2;
3. Down through the separating pin, and pass through
between the tension plate 3;
4. To left pass through the thread control complete 4;
5. Up through the upper thread guide 5, then to left
through the thread take-up lever threading hole;
6. Down through the middle thread guide 6, lower thread
guide 7 and needle bar threading hole 8, then pass
through the needle hole 9 and draw out the thread
approx 100mm from the needle hole.
1. Open the right slide plate A;
2. Open the stop latch thumb lever B;
3. Draw out the bobbin thread 50mm from the bobbin case,
insert the tip of the bobbin thread into the slit of the
bobbin , and then pull the bobbin thread so that the
bobbin will rotate clockwise.
4. Put the bobbin case into the bobbin;
5. Close the stop latch thumb lever B;
6. Hold the needle thread by left hand, and turn the balance
wheel by right hand to put the bobbin thread aside;
7. Close the right slide plate A.
