Restoring the correct torque:
Setting steps
1. Loosen the coupling screw (7).
2. Using a screwdriver, turn the disc on the setting slot (5) such that 8 Nm
is reached for the torque:
• To increase the force: Turn in the + direction
• To reduce the force: Turn in the - direction
3. Tighten the coupling screw (3).
Risk of crushing
Switch off the sewing machine before checking and setting the
safety snap-on coupling.
WARNING
Machine damage due to incorrect torque
If you change the torque, it could be that the coupling will not disen-
gage although this would be required. This could cause machine
damage, e. g. in the event of the thread jamming.
Do not change the factory setting and make sure that the torque
remains at 8 Nm.
