The differential ratio has been set from 1:0.7 to 1:1.4 at
shipment.
When aligned the differential feed lever(right) with the
line of the differential feed graduations, the movement
of the differential feed dog is the same as that of the main
feed dog (differential ratio 1:1), resulting in uniform sewing.

the differential feed dog.
To increase the movement for gathering, turn it clock-
wise.
