Hi from Spain

I want to fix my headlight's SP500. I read manual instructions some stuff about 3 screws to manage it : up/down, right and left. I found two of them (right and left scres) but not the center one to try up/down axe. Do you know how to handle this kind of movement?
Thanks in advance

 

There is a large thumb wheel on the bottom of the headlight pod. When your sitting on the seat, feel around under the pod on the right side towards the back of the pod. You can turn this wheel to adjust the up and down. Don't push too hard or you'll pop it out on the inside.
