My experience is that Festool = employee in a position corresponding to your question/problem/ will answer you, personally, if you e-mail them.
If you fear your e-mail might get lost in that big inbox/ doesn't make it to the right destination, I can offer to forward your findings, to someone at Festool who's E-Mail I have, on your behalf.
But from my experience, you will be gtg by e-mailing Festool (Germany) yourself: info (at) festool . com or customerservice-de (at) festool . com
Kind regards,
Oliver
