Motor Switch.

3.
Thread Controller Spring.
The function of the thread controller spring is to hold back the slack of the needle threads until the eye
of each needle reaches the goods in its descent, as without this controlling action of the spring, the
slack thread will sometimes be penetrated by the point of the needle as the needle is descending. For
more controller action on the thread, loosen the stop screw at the right of the tension and set the stop
lower. For less action, set the stop higher.
