Amada Rg 25 Manual
I have a similar press (mine is a rg-103) but the controller is different (hurco auto bend 5). If you have question feel free to ask.I have a Promecam IT2-50-20 (50t, 2m) with an Autobend 5 as well. Someone harvested the VFD (or was it LED?) display from it, but it still has the other boards. Fortunately, I have all the manuals / schematics. My plan is to add a microcontroller to translate the display output to drive an IBM cash register VFD module just to get it working again. Down the road it might be fun to create a custom touchscreen app with a rasberry pi or beaglebone black instead of the controller it has now. In any case, I just wanted to post to this thread so we Promecam / Autobend users can find each other.
I'm having some issues with the foot control on mine. The foot control appears to be hydraulic, and it seems to be working weakly / sporadically, almost like bad brakes on a car that you need to pump.
Sometimes you depress it and the ram comes up strongly, sometimes weakly (the ram rises partially and then you hear what sounds like hydraulic fluid bypassing), many times not at all. I'm thinking there is air in the control line or it is otherwise lossy in some way. I haven't done any really high tonnage bending yet, but it does seem that when it works it is able to generate reasonable force. I guess it is possible that the tonnage / max pressure control isn't working right instead. I have it maxed out right now though. I'm having some issues with the foot control on mine.

We got it for 1200 bucks because it wouldn't build any pressure-the seller just wanted it gone.

On our machine the pump is in the reservoir and is chain driven by an externally mounted motor. Pressurized fluid flows from the pump through a hard line that connects to a bulkhead fitting which in turn passes the fluid through the wall of the reservoir and on to the ram. When I pulled the cover off the reservoir I discovered that the large nut on the inside of the fitting was only finger tight and when I operated the machine all the oil was p.ssing back into the tank and never making to the ram.

Five minutes with a big crescent wrench got it tight and now the machine makes full pressure and works like a hot damn.
