You'd be surprised how much static is built up on the system. If you're
moving it around the shop at all you'll want to ground it so you don't get
shocked every time you touch it... and continuously while your touching it.

As the other reply points out people worry about dust explosions and such, I
agree with him I don't think it's a real danger.

I bought a dust collector tonight. What is the idea behind grounding the
hose? I assume to reduce friction. So do I connect it to a pipe and hook
it to the tool itself or what?

Thanks...
