1. Balance Wheel: This should always turn towards you when
sewing.The function of the balance wheel is to raise and lower the
needle.

2. Step Motion Screw: Loosen it when filling the bobbin so that
the needle remains stationery. Tighten it when sewing. It
disengages the needle.

3. Stitch Length Regulator: Adjusting this alters, the length of the
stitches. The numbers alongside indicate the number of stitches
per unit length.

4. Bobbin Winder: Insert the bobbin into the winder when filling
the bobbin with thread. It holds the bobbin in place.

5. Feed Plate: This helps to push the material forward.

6. Presser Foot: Lower presser foot just before sewing and raise the
presser foot before removing the finished work. It holds the
material firmly in place during stitching.

7. Needle Clamp: To insert needle, place flat side to the right.
Tighten and the needle will be held firmly in place.

thread.
