10. Position of needle in needle hole in sewing direction
Requirement:
There must be a clearance of 0.2 mm between the back edge of the needle shank and the back edge of
the needle hole in the needle plate (fig. 29).
Note:
Since system 130/705 H needles increases in size at the needle front side only, the point of an Nm 100
needle is positioned exactly in the middle of the needle hole (as seen in feeding direction), while the point
of an Nm 80 needle is positioned slightly closer to the back edge of the hole.
Check:
● Insert a new needle of system 130/705 H in size Nm 100.
● Select stitch pattern "01" for straight stitch.
● Attach zigzag foot.
● Lower zigzag foot.
● Turn the handwheel until the needle is in its lowest position.
The needle must now have the same distance to the front and rear edges of the needle hole in the foot
and the needle plate.
