Black dust?

[ssgtob1]

I bought a 21esin the autopia open box sale and just used it today. It is letting off a lot of black dust from where the backing plate touches the gasket(?). Is this normal?

Oh, so washer or no?

Oh, so washer or no?

since that thread has such a potpourri of information, some of it conflicting...

i'd do all of the following and in this order:

1. contact Rupes so they can confirm it's normal or not.

2. contact Autopia/Autogeek as backup.

3. run it for a while and see if it stops since that seems to be a common complaint.

Yes, it's normal. I have a 15 & 21, and they both did what yours is doing.

my duetto doesn't have that issue, I will test 21 coming on the way.
