TU56 restoration

I am supposed to be getting a TU56 DECtape unit today. I believe it was functional when it was retired, but it supposedly now has a grimy film on it. My plan is to assess its condition, then clean it up. I need to study the manual and technical drawings, but my question is: Can I easily test the mechanics, on/off switches, lamps, motors, etc, without hooking up the TC11? I think there is a local mode switch and wondered what all could be tested easily without hooking up the TC11. I will be studying the documentation to get a better idea about things. I have a TC11 that also needs to be cleaned up. It has a layer of dust on it and needs a couple boards, which should be here soon. The goal is to get it hooked up to my 11/40 eventually. I have a number of DECtapes. Thanks for any advice that anyone might have, Ashley
