4. Feed Mechanism
a) Clearance between Throat Plate and Feed Dog
Ensure that the feed dog does not touch the throat plate
as it passes through. A clearance of 1.5mm should be seen
between the middle teeth of the front feed dog and the
throat plate as indicated (Fig.8).
b) Height of the Feed Dog
Adjust the height of the feed dog so that it protrudes
2.5mm from the upper surface of the throat plate when the
feed dog has risen to the highest position, as shown in
(Fig.9). If the feed dog is higher than this, stitch will not
chain satisfactorily, and if it is lower than this, the stitch
width will be too small. Slacken nut
