With elastic sewing threads, e.g. synthetic fiber
threads, a certain needle thread quantity must be
pulled out for sure stitch formation.
This occurs in the low position of the take-up lever
in conjunction with the thread regulator 1.
For this the thread regulator is set as follows:
–
Bring the thread regulator into its lowest
position.
–
Adjust the thread regulator.
With elastic threads:
The thread hole must be visible below the thread
regulator.
Thread the needle to the left past the bar. Illus. a
With non-elastic threads, e.g. cotton:
Thread hole should be visible above the thread
regulator.
Thread the needle thread to the right past the bar.
