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
A wide range of fabric can be overlocked on this machine, but it is recommended to tighten screw

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.
