Raising the pick-ups up to give me a darker tone on my humbuckers?

I have a Dean Dime o' flage(my first guitar), and was wondering how i would go about raising the pick up's on it. They're the basic, Dean zebra pick-ups. Any thoughts or advice would be greatly appreciated.

Turn the middle screws to the sides of the pickups. Turning one way lowers, other way raises.

Cheers, i'll have a bit of a fiddle about, without breaking my guitar hopefully...
