(13) Adjusting the feed dog
4. Longitudinal position of the feed dog
(1) Position of the main feed dog : it is the standard that the position where the clearance from the edge of the
slot of the throat plate to the front face of the main feed dog is 0.6±0.2 mm at the position where the main
feed dog travels to the extreme front position (operator's side) when feed momentum is set to 3.6 mm
(maximum).
(2) Position of the differential feed dog : it is the standard that the position where the clearance provided
between main feed dog and differential feed dog is 1.6±0.2 mm when the differential feed ratio is set to 1 :
1 after adjusting the position of the main feed dog.
