Thread regulator
Caution: Danger of injury!
Turn off the main switch.
Only check and adjust the thread regulator when the machine is
switched off.
Standard checking
The position of the thread regulator 1 depends on the thickness of the
material, the thread thickness and the selected stitch length.
It must be set so that the thread is fed round the hook in a controlled
manner.
The greatest amount of thread is released at setting “1" as it is
required for particularly long stitch lengths and thick sewing threads.
–
Open the throat plate slide.
–
Thread the needle and hook thread.
–
Insert the material.
–
Start sewing for a short time.
–
Turn the hand wheel and observe how tightly the needle thread is
being fed around the hook.
Correction
–
Undo screw 2.
–
Move the thread regulator.
Thread regulator to the left = more thread
Thread regulator to the right = less thread.
–
Tighten screw 2.
