This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

Good quality, all schematics of few of models. There is also short form of user manual and regulation manual.
;
Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

5-4-4. Adjusting the Tu guide
After replacement of Tu guide preset and adjust the height. (1) Tu guide height presetting (Figure 6) Adjust the height from the upper surface of mechanism chassis to the upper surface of lower flange with the aid of jig.

If the tape running position in case of V/S R is lower than the running position in case of V/S F, turn counterclockwise the Tu guide nat.

5-4-5. Checking the V/S F and R waveforms (Figure 8)
(1) Playback alignment tape (VR2ABOPS), and set the V/S R mode. At this time ascertain that the waveform crest pitch is kept constant for more than 5 seconds. (2) Set the V/S F mode. At this time ascertain that the waveform crest pitch is kept constant for more than 5 seconds. Unless the constant pitch is obtained, execute the checks of Section 4-2, 3, and 4.

5-4-6. Checking after adjustment
(1) Envelope check 1 Playback the alignment tape (VR2ABOPS). 2 Ascertain that the envelope maximum to minimum ratio is 65% or more. (Figure 9) 3 Ascertain that the waveform does not change remarkably. (Figure 10)

4 After V/S F, R and FF/REW execute playback, and ascertain that the RF waveform rises horizontally within 2 seconds. At this time ascertain that there is no tape slackness near the pinch roller. Tension pole (3) Checking the tape travel 1 When the tape is played back, ascertain that tape lift and tape curl of 0.3 mm or more do not occur at the lower flange of Si roller, upper flange of Sup GR, upper flange of Tu GR, and upper/lower flange of Tu guide. 2 In case of V/S F and R ascertain that no curl is found at each flange.
