SETTING DIFFERENTIAL FEED
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.
FOOT PRESSURE REGULATOR
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 foot pressure regulator to
higher number to increase or to lower number to decrease
pressure.
SEWING WITH EXTRA HEAVYWEIGHT
FABRIC 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.
