We had a Verson 90 ton at the bottom stroke press brake here and the service manual was about 10 pages, we sold the Verson and I gave the manual to the guy who bought it. That said ours had a Twin Disc clutch and if yours does you can go on line or contact Twin Disc for adjustment, it's dirt simple. Lubrication is pretty basic, we used standard gear oil in the reduction box and spray on gear lube on the bull gear.
Adjustment of the upper ram as more of an experiment, it took us a little bit but we got it dialed in over time.
Maybe someone out there has the same model and they could burn off a copy for you.
