NEC DS8000U VCR where to find manuals? Belts? Codes?

Some decks both beta and VHS it's normal to keep the drum wrapped all the time the tape is in, others unwrap for Stop-fastwind/non-visual searching. It basically depends on the OEM who made it.
I don't like it when it stays wrapped in those cases either.

I you want a recommendation on a brand that doesn't do that look for a mid-90s Sharp with rapid rewind...I was given a lower tier one new for my 5th or 6th birthday and it STILL works great all these years later. A few years ago I was elated to find one of their S-VHS decks for cheap at a thrift....That thing may outlive me.
