GETTING READY TO SEW –

Set by simply turning the differential feed control dial in the direction desired referring to the chart below.
The adjustment can be made between 0.7 (negative effect) and 2 (positive effect). These settings give the best ratio of feeding.
For normal sewing, the dial should be set at 1.
The dial can be reset even while sewing.
Presser foot pressure has been correctly set at the factory, so you do not
need to adjust it for most of ordinary sewing. If adjustment is necessary,
turn the presser foot pressure regulator to higher number to increase or to
lower number to decrease pressure.

mended to tighten screw as illustrated, when sewing with extra heavyweight
fabrics or multiple layers of fabric. Open working table for adjustment.
Loosen the screw when sewing with light to normal weight fabric or turning
overedge cutting width dial, or otherwise fabric may not be well cut.
The machine is set for normal weight fabrics from the factory.
