2.13 Bobbin winder
Caution: Danger of injury!
Turn off the main switch.
Only check and adjust the bobbin winder when the machine is
switched off.
Standard checking
The winding procedure must stop automatically when the bobbin is
filled up to about 0.5 mm below the edge of the bobbin.
The bobbin wheel should have no axial play but must also run
smoothly.
