How To Aim Headlights?

Can't seem to find instructions on head light aiming in the service manual. Can anyone shed some light on this subject. (Sorry for the pun) I suppose if I proceeded as if to replace a bulb, I would find the adjustment. Both beams seem low on my SWing. I'd like to get a flasher or two on Hi beam, for my esteem's sake if nothing else. Thanks for any input anyone might offer.

Thanks a bunch. It even looks like they intended it to be adjusted. The procedure is on page 3-20 in my manual, though the maintenance schedule says it's on 3-19. I will have to give it a try, once I find the knobs and can remember which way CW and CCW are.
