6.4 Adjusting the thread regulator
The thread regulator 1 regulates the amount of needle thread necessary for stitch
formation.
The setting depends on the following factors: - material thickness
- yarn characteristics
- stitch length
A properly-adjusted thread regulator ensures an ideal sewing result at a minimum
needle-thread tension.
At the correct setting the needle-thread loop must slide at low tension over the thickest
point of the shuttle.
Caution - danger of injury!
Turn off the main switch.
The thread regulator may only be adjusted with the sewing
machine switched off.
