6.5 Adjusting the thread regulator
Caution: Risk of injury!
Tur n off t he main switch.
The thread regulator may only be adjusted with the sewing unit
switched off.
The thread regulator 2 controls the quantity of needle thread required
for stitch formation.
The thread regulator must be precisely adjusted for an optimum
sewing result.
With correct setting the needle-thread loop must slide with low
tension over the thickest point of the hook.

Loosen screw 1.
–
Adjust the position of the thread regulator 2.
Thread regulator to the left = more thread
Thread regulator to the right = less thread
–
Tighten the screw 1.
Adjustment information:
If the maximum quantity of thread is required the t hread-tensioning
spring must be pulled upwards about 0.5 mm from its lower limit
position. This is the case when the needle-thread loop passes the
maximum hook diameter.
