Hello,

I have inherited a Craftman Table saw from my Dad. I think I can
recollect that my Grandparents got it for him when I was a youngin'.

I just purchased a new belt for it, I don't think my Dad ever put a new
one on it. Anyway, in order to raise or lower the blade I have to loosen
a bolt on the motor pivot and then retighten when I have the blade
height set.

How is this suppose to work? I sure don't recall seeing any of the home
improvement shows or Norm adjusting this bolt when raising or lowering
the blade.

Thank you,
Fred

The purpose of the bolt is to reduce vibration of
the saw. There is suppose to be a special washer
on the bolt that allows you to tighten to the
point the bolt doesn't vibrate loose but still
allows the part to slip. If you tighten it too
much, and don't loosen it when you raise the saw,
it will shear the bolt. That was the condition of
my dad's saw until I got the broken piece out.
Just put any washer on it next to the head,
tighten until vibration decrease with a running
saw but not much more than finger tight. Lift the
motor up by hand (or try) to assure that it will
move with only slight binding. (or keep a small
wrench handy to loosen and tighten it every time
you raise and lower the saw blade.
