Leibinger numbering machine torque

[SpearChucker]

Does anyone know the correct torque setting for mounting numbering boxes to the rings on a numbering machine in a QM46-2? Heidelberg will sell us a new preset torque driver for $400 or we can buy an adjustable for $100 if we know the torque. Heidelberg won’t tell us the torque spec.
