Question about ice skate's blades?

I just got my new ice skates yesterday, but it came with these screws for the blade. They didn't provide any instructions fir how to do it, but on the bag it stated to insert the safety screws on the blade after final adjustment? The blades are already attached and adjusted but there are empty holes for the screws provided. Do we just screw it into the holes? Should I just take the skates into the shop and let them do it or should my dad just screw it in?
