STITCH FORMATION
10-1 Position of the needle thread guides
The distance from the center of the eyelet of the
needle thread guide to that of the set screw should
be approximately 17.5mm (see the illustration).
Adjust the height of the thread guides by loosening
screws A and moving each thread guide up or down
(refer to the distances shown in the illustration).
If the stitch formation cannot be changed extremely
by adjusting the height of the thread guides because
of the thread to be used, unravel the thread after
test sewing and adjust the height of the thread
guides while checking the tension of the needle
thread.
