umm try loosening them or just messing with them in general until they work haha? I dunno really what you're asking. Annd you'd probably be better off sending an email to razor asking about it..
My little brother has one so I can answer. No, they are like training wheels, if you manual it stops you from looping out. He tried putting on skateboard wheels and it sort of worked, it just isn't good. I suggest take them off completely.
