g. Only for the first circuit, if necessary set the gear lever on the machine gear box, depending on whether
you want to work with the normal scaling dynamometer (0 a 50 KN) or if you want to use a FINE scaling (0
to 17 KN).
ATTENTION: Never change the position of the shift lever without first discharging
the line pull, in order to avoid the loss of the rope / conductor.
h. Choose machine usage configuration: Fully independent circuits, electronically connected circuits or
coupled circuits. (see chapter 5.5.2.3).
