THREADING THE BOBBIN CASE

Step 1 (illustrated in Fig. 5) Hold bobbin case between thumb and forefinger of left hand, so that the slot in the edge of the bobbin case is on top. Take the bobbin between thumb and forefinger of right hand so that the thread on top leads from left to right. Step 2. Insert bobbin into bobbin case, pull the thread into the slot of the bobbin case as shown in Fig. 6, and draw it under the Tension spring and into the fork-shaped opening of the spring as shown in Fig. 7.

ADJUSTING THE TENSIONS

A correct stitch can be obtained by varying the tension on the

needle thread. To adjust the tension of the needle thread, Lower

the pressure foot.

Adjust the tension regulator as the case demand, by reffernng

to iUustration. (Fig.ll) The quality of sewing depends on the tension of thread. Therefore, it is necessary for the user to

become fully familiar with the correct tensions through practice.

Before adjusting lower tension be sure that the machme is

threaded properly. When necessary to change the bobbm te^n,

turn small screw (Fig. 12) on side of the bobbin case clockwise to tighten, counter-clockwise to loosen.

When the upper and lower tensions are properly balanced,

perfect stitch will be formed with both threads interlocking in

fabric (Fig. 13). , , . n j
