haha, 8? you're a moron, this kid sounds like he's 10, don't take advantage of his young age to mess with him...
that being said, OP, you want to get the biggest screwdriver in your dad's tools and turn the big screw on the toe and heel of your bindings as far right as it will go. It will get hard to turn, but go all the way until it stops. then your dings are ready, sometimes they lose charge and it will drop, that's what the numbers are for, to show you when to recharge. I always recharge before 10 at the latest, try to keep your charge meter as high as possible at all times. That will ensure that your bindings work properly.
