Setting the needle thread regulator
The needle thread regulator regulates the amount of needle thread
required for forming the stitch. An optimum sewing result is pos-
sible only when the thread regulator is exactly adjusted.
Proper setting
With the correct setting the needle thread loop must slide over the
thickest part of the hook at low tension.
When the largest thread quantity is required then the thread
tension spring (3) must be pulled approx. 0.5 mm down from its
upper end position. This occurs when the needle thread loop
matches the maximum hook diameter.
