PREPARiNG TO SEW To remove the Bobbin Case Turn the hand wheel toward you until the needle bar is at its highest point. Open the slide plate in the bed of the machine so that bobbin case can be reached. (Fig. 3) Inscrt the thumb and forefinger to open the latch and withdraw the bobbin case. While the latch is held open the bobbin is retained in the bobbin case and will not drop out. (rig.

To regulate the tensions For ordinary stitching, the tension on the upper and lower threads should ba equal so as to lock both threads in the center of the fabric. thus: If the tension on either thread is stronger than on the other, imperfect stitching will be the result. If the tension on the upper thread is greater than that on the lower thread. it will lie straight along the upper surface of the fabric, thus: If the tension on the lower thread is greater than that on the upper thread,
the lower thread will lie straight along the under-side of the fabric, thus :
Tension

The sewing machine will give perfect per formance when the upper thread tension is correctly adjusted.

B) Contrariwise,
the upper thread tension becomes weaker when the dial is
turned in the direction marked (—).
C) Once the tension has baen adjusted satisfactorily, the dial can be returned to the same dial-number to ootan the same results.
Tension on the lower thread The tension on the lower thread is regulated

Note : Do not crowd fabric into the scroll, nor leave the scroll only partly filled with fabric. Instead of a straight stitch. you can also use a zigzag stitch for this hemming operation.
Be sure, however, to adjust the width of the zigzag stitch so that it is
as wide as the hem itself. Using a very long stitch and tight tensions will produce a SHELL STITCH.

THREAD BREAKS If the needle thread breaks, it is probably due to one of the following causes:
The machine being improperly threaded. The tensions being too tight. The needle being bent or having a blunt point. The thread being too coarse for the size of the needle.
