How much tension on belts?

I’ve not used belts before in anything so I don’t know this… How much tension should be on the belts? Is there a way to determine when you’ve set the tension correctly? Is there a wide range that works or do you have to get it close to optimum? I worry about overtightening them because with the ziptie system, you can’t let out slack.

There are some notes about this in the instructions. Start loose, check you dimensions, stop tightening when you are happy. It should be a lot less than you think, 5-8lbs if I remember right.

Thanks… I looked all over the instructions before posting and didn’t see anything regarding tensioning the belts.
