Hi

The interesting thing is the URM-32 has a fitting that looks a lot like 
a tire stem mounted on the chassis. I assume it is either to pressurize 
the sealed chassis or to dry it out. Pressurized dry air seems to be an 
unusual thing to have around the shop. Definitely need to take a look 
at a manual.

I suspect that it's been thirty years since this box saw a real depot 
so it's not to surprising that the dry chassis has leaked a bit.

	Thanks!
