Amada RG-80 with Hurco Autobend 7

Hi ppls, not sure if I'm posting in the right section
Using an Amada RG-80, I don't have that much time on it, but it seems like a good machine
One problem, it's an Up-acting lower beam machine... I can't seem to set the lower limit setting with the lever on the front of
machine....When the lower beam is at a height that is more suitable for parts being bent I'm assuming I push the lever to the down position
The problem is it doesn't seem to do anything, the lower beam goes all the way to bottom stroke
I can set the speed no problem with the other lever in behind it but I would like to get that low limit lever working
Any thoughts?

Thanks, Bill

Almost forgot about this post
It was an easy fix... pulled the front cover off and lubed some parts that lock the height in place
