TO ADJUST PRESSURE ON PRESSER FOOT
For releasing pressure on the foot, press down the
ring (A), which will allow the pressure regulator to
spring up to its highest position and leave the
material free from any pressure from the presser foot.
For sewing thin or light fabrics, press the top of the A
pressure regulator (B) down lightly to get the
required slight pressure of the fabric.
For sewing thicker or heavier fabrics, push the top
of the pressure regulator down further, in order to
get a stronger pressure on the presser foot.
TO USE DROP FEED DEVICE
Darning and embroidering is facilitated by means of the drop feed
knob (1) on the right hand corner of the bed.
When this knob is set at "EMBR", the feed teeth (2) drop below
the surface of the needle plate so that it will not interfere with
the free movement of the cloth.
The feed teeth will return and resume their normal operation
when the knob is set at "NORM".
For sewing light materials like silk, it may be set at "SILK"
position in order to avoid puckering the material.
