TO ADJUST THE TIMING OF THE NEEDLE
AND THE FEED DOG
Correct Setting:
When the tip of right needle is at 2 to 4 mm above the needle plate in its downward motion, and
presser foot lowered, the top of the feed dog teeth should be level with the top surface of needle plate
at their rearmost position.
Before adjustment, check if the needle bar height and the feed dog height are correct.
To adjust:
1. Set the stitch length dial at “ 3 “ and differential feed dial at “ 1.0 “ .
2. Remove the back cover unit.
3. Raise the presser foot and move the tip of right needle at 3 mm above the needle plate in its down-
ward motion by turning the handwheel.
4. Lower the presser foot, and loose two setscrews A for main feed cam, two setscrews B for sub feed
cam, and adjust the position of the sub feed cam and tighten setscrews B.
# Turn the sub feed cam to the direction C if the feed dog is lower than the surface of the needle
plate.
# Turn the sub feed cam to the direction D if the feed dog is higher than the surface of the needle
plate.
5. Set the main feed cam to keep the clearance between the bushing and main feed cam to about 1
mm, and tighten two setscrews A.
6. Attach the back cover unit.
