One way to verify this distance is described below.
28. Replace any needle with a drill blank (or straight wire) with a diameter of 1.6mm (0.0625in) and a
length of approximately 30mm (1 3/16”).
29. By rotating the upper z-shaft, move the corresponding needle bar down until the presser foot
reaches its lowest position.
30. The distance between the drill blank and the inner surface of the presser foot should be approxi-
mately between 1.5mm and 2mm. To check this distance, first place a 1.5mm (1/16”) hex wrench
between the drill blank and the presser foot.
•
If the hex wrench does not fit, the distance is too small (proceed to step 31).
•
If the hex wrench fits, you then need to verify that the distance is not too large. To do this,
place a 2mm (5/64”) wrench between the drill blank and the presser foot. If it fits snugly, the
distance is correct. If it fits loosely, then this distance is tool large (proceed to step 32).
31. If you determine that the distance needs to be adjusted, carefully bend the presser foot in the
appropriate direction, then repeat step 30 to check the distance. Repeat this process until the
distance is corrected.
32. Verify that the presser foot is not interfering with the grabber trap (see image below).
33. To adjust the presser foot height if needed, see the presser foot height adjustment section.
