SETTING DIFFERENTIAL FEED
Set by simply turning the Differential feed control lever 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 lever should be set at 1. The lever can be reset even while sewing.
