I have a Thyssenkrupp Vertical Express hydraulic elevator, and I'm woefully short on technical knowledge. The helpful "users manual" provided with my equipment basically has one page that says, "if something is wrong with your elevator call a technician." That's great, but because of my agency's procurement guidelines, I need to hire two technicians, one to tell me what's wrong with the elevator so that I can write a bid specification and another to repair the elevator.

I would like to have a more advanced, maybe installation and alignment manual, or a full-blown service manual, but the companies in my area are reluctant to sell me one. How can I acquire one of these documents?

The elevator is a Thyssenkrupp Vertical Express EP08020 serving two floors which I understand is nearly identical in design to a Thyssenkrupp TAC22.
