ADJUSTING MOVEMENT OF
DIFFERENTIAL FEED DOG
The differential ratio has been set from 1:0.6 to
1:1.1 at shipment.
When aligned the differential feed lever (right)
① with the line② 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.(Fig. 28)
(1)Loosen the lock nut③.
(2)Turn the adjusting screw④ to adjust the
movement of the differential feed dog.
To increase the movement for gathering,
turn it clockwise.
To decrease the movement for stretching,
turn it counterclockwise.
