The bobbin thread winder of this machine is built-in to the frame of the machine.
To wind the bobbin thread, fi rst insert the bobbin to the bobbin winding shaft ❶
as far as it will go. Next, pass the thread to bobbin thread guide base ❸ and
bobbin thread winder guide ❷ , as shown in the fi gure, and wind the thread to
the bobbin several times from the bottom. Then, push in the bobbin trip latch ❹
and rotate the machine. When the fi xed amount of thread is wound, the winding
❸
will stop automatically.

During the running of the machine, sometimes the thread gets caught by the
sewing hook, causing an unnecessary exertion to the machine. In such cases,
the safety device goes into action automatically to prevent damages to the ma-
chine. When the safety device is acting, the feed and the sewing hook do not
move even if the handwheel is rotated.
When the safety device is acting, remove the cause of the defect and set the
safety device to the original status by the following method:
1. While pushing the push button ❶ , push the auxiliary handwheel and rotate
strongly toward the left direction.
Be sure to verify that the safety device is set and then operate the machine.
2. When the safety device jumps into action quickly, remove the timing belt and
rotate the adjusting screw ❷ to right.
Conversely, when the safety device does not go into action and the machine is
damaged (needle, sewing hook, etc.), rotate the adjusting screw ❷ to left. With
a slight force, the safety device will spring to action.
