5.6.3 Adjusting the needle thread quantity

WARNING
Risk of injury from moving parts.
Switch the sewing machine off before adjusting
the thread regulator.
The needle thread quantity released for stitch formation is deter-
mined by the position of the thread regulator. The required thread
quantity depends on the thickness of the sewing material, thread
strength and seam type. For different threads and seam types,
the threading procedure also differs ( pg. 23).
