Mirka vibration Alan keys

Hello, I just bought a new mirka deros 5650cv sander and I tried to get the Alan keys out to change the vibration but they are super tight and one is starting to round off, I am doing it the right way. 🙂

Any tips to get these out?

Thanks. 

I’m not going to be any help to you, but that looks like a dang fine unit. Congrats! I’ve been drooling over them for a while, but unless Uncle Powerball comes through for me, I won’t pull the trigger…

Thanks, it is a very good sander been using it to smooth out some rough walls, working very nicely apart from them Alan keys.
