There's no real way to tell how tight it is (unless you buy a belt tension gauge, do a search, I've asked about this before). Basically what I did was tighten it to what I think it should be, if it squeaks turn it off and tighten it some more, if it doesn't let it run for about 10 mins and check the tension, if the belt isnt any looser than when you put it on its probably too tight, if it is a little looser than tighten it up to the way it was when you started. If you push on the belt it should only move like 1/4-1/2 inch. Hope this helps.
