It is easy to adjust. Take the boot out of the binding; turn the screw, you will hear it click about once every quarter turn. Count the clicks so you will know how far to come back if you go too far. Put the boot back in securely, clamping the binding down. Check the forward pressure. Repeat as needed.
The only fly in the ointment, is that the clearance on some boots and barons could be very limited. For some reason there have been reports of folks not being able to get the screw flush AND get the boot in the binding. I would have to see one in my hands to figure out what's up with that . In the mean time, if it don't work, you can just back the screw back out again. No harm done.
