Just got my Acedeck Brack Friday Bunduru (yea i order it in November!) Like regular skateboards how tight should my bolts be? Also wheel bite?

Super pumped i finally got it, but a few things are not clear, the manual does not give me any indication of how tight should my bolts be, on my skateboards we all leave a bit of leeway to let the wheels spin a bit more, is that true here as well?

One wheel is spinning and burning rubber. Any ideas of why that could be? Lastly, how do yall get straps on your feet? i cant see how i would install it and also, having the battery in the middle means i will hardly ever put my feet down and up to push right?
