I'll see if I can do anything about the pictures in the manual. Otherwise I can always walk you through changing bulbs, etc... Or I can send a few digital snaps to show you.
Thanks for your help.

I managed to locate a button on the back of the head - it's red, and is not easily accessible. Is it used for extra filtration, ot is that a fuse?
What are the chrome knobs/screws on the underside of the head? Are those used for alignment? (There are two on the sides, and one in the center - at an angle of about 45 degrees...)

I can provide more photos, if necessary...
