Kubota Kx101-3 @2 adjusting AUX oil flow

Hi!
I was wondering if someone know how to do this. (I don't have the instructions to the control panel.) The maximum oil flow rate of the additional control circuit can be changed/adjusted by simply pushing a switch—there’s no need
for additional tools or manual adjusting
procedures. This simplifies the utilisation
of front attachments like tilt buckets,
brush cutters and hydraulic hammers—
you can reduce or increase the flow to
get just the right amount of control.

Thanks
Thomas
