Even if you find some way to remove the pad now, you'll still eventually need a spanner at some point. Just call Festool and order part number 411717, $10.08. You'll probably receive it in 4-5 days...at least that was the case pre-Louis DeJoy.
Which Portland are you asking about? West coast or east coast Portland. I’m located near the west coast Portland and have a RAS and the associated wrench you are looking for.
