Gentle persons -

I bought a floor model Jet 14 inch bandsaw from Lowe's. I downloaded
the manual off the website and followed the directions for setting up
the saw. When I turn it on, the blade comes off within seconds, I
have tried more tension and less tension. I have tightened all the
bolts. I checked that the tires are aligned on the wheels.

What other things can I try, is there a good book on the subject.
Basically ---- HELP!!!!

I want to thank you all in advance, I enjoy my reading of this group
and the help you provide. I have archived dozens of threads on topics
that I refer to when I work in the shop.

In addition to the suggestions made by others that the top wheel is out of
adjustment, remember this rule:

If the blade comes off its wheels TOWARD the operator, the bottom of the
adjustable wheel (usually the top) has its bottom canted too far to the
rear. If the blade comes off AWAY FROM the operator, the adjustable wheel's
bottom is tilted too far forward.

Or it might be the reverse; I forget.
