    Need Festool Vac Help!

    My CT33 has been actually really strangely. Randomly, I hear the vac powering up and down and up and down, like a sine wave. Anyone experience this before or know what's going on?

    brushes worn out , or close ? 33's are pretty old now.


    I'd also check the switch module as they tend to gunk up with dust.

    Isn't there a potentiometer on there to make it variable speed? That probably has dust in it, or the internal wiper has just gone bad.

    Have you checked the bag? I think they do that sometimes when the bag is nearly full. Or the filter could need to be cleaned. Check both of those first!
