My new bandsaw (an 18" Jet) has a blade tensionong indicator that you can
read on the inside and the outside of the upper wheel housing. It would be a
nice feature - if the two scales agreed with each other.

So I asked Jet which if any was correct. I first got pointed to a 800
number, but as I live in Australia - that wasn't a lot of use. So they sent
me the following:

"Regard the gauge for the tension on both inside and outside of the wheel is
for your ref. for different width of blade , it is only for ref. re-set the
different blade tension , normally you need to adjust the tension of blade
by yourself till the blade is not losing when you cut your wood .
It does a discrepancy on attaching the label gauge to the unit and cause
both ( inside & outside ) reading is difference but it should not affect the
function of this band saw .
So we don't suggest you to return this unit due to one of the label is not
in position , unless you have problem to operate this band saw .
It will be highly appreciated if you would advise which dealer do you buy
this unit from , and you could contact them at your convenient for your
inquiry . "

I don't know why they didn't say that in the manual!
