Feed system
3. Setting the main feed dog in the sewing direction with regard to the needle plate
Requirement:
When the stitch length is set to “4”, the main feed dog must be centered between the front and the back
of the needle plate in the sewing direction (figure 4).
The main feed dog must also be centered laterally.
Check:
● Loosen the screw 1 to the presser foot holder (figure 5).
● Remove the presser foot holder 2.
● Set the maximum stitch length and the standard differential stroke.
● Turn the handwheel in the normal direction until the feed dog is parallel with the upper surface
of the needle plate.
● Carry out a visual check.
Setting:
● Remove the housing cover as described in the adjustment and repair instructions.
● Set the maximum stitch length and the standard differential stroke.
● Slightly loosen both fastening screws 3 (figure 6).
● Move the feed dog carrier 4 until the feed dog is centered in the sewing direction as well
as the lateral direction.
Repeat this procedure until both settings are correct.
● Tighten the fastening screws 3.
Test:
● Check the lateral distance between the main feed dog and the needle plate.
● Check that the machine runs freely with the maximum stitch length set.
