There is a small screw at the base of each of your brake's arms. Tightening that screw should make the arm move outward.
Honestly, if it was my bike I'd buy a set of lower end Shimano brake arms and ditch the ProMax. You'll only have to do that once. Keep the ProMax and you'll be jacking with them constantly.
