Hi Bill. So far I have not been able to find a manual, but I will keep looking.
In the mean time, if you want to give it a try, it appears to me that the circular piece that has the fingers that hold the light globe is probably put in place to hold the globe by a "turning" motion.
If you were to reach up and grab this ring and gently turn it counter clock wise I bet it would turn perhaps 1-3 inches and disengage the fan body.
Makes sense that the manufacturer would make it easy to change light bulbs and viewing the fan, this would be about the easiest way to do it.
I would assume the glass globe is NOT fastened to this ring in any manner, so if you do decide to try this, be ready to have the glass globe release from the holding ring.
I will let you know when/if I find a manual.
If you decide to try my solution and are satisfied with it, I would appreciate a Thumbs Up rating from you.
BTW, nice fan.
I found the Manual to the F603 in pdf format at: http://minkagroup.net/Admin/UploadFiles/F603-English.pdf It describes how to put bulbs in so it was simply a matter of reversing the instructions to get the old ones out. However, it is not that easy to get the bottom section off so one has to be careful or you will twist the whole unit instead of just the bottom part..... I think what you did was push up too hard and then turn the whole unit. Try pushing up firmly but at the same time hold some fingers (or have someone help in this) on top of the bowl above the fan blades and then twist counterclockwise an inch or two and the bottom part will release (don't let it fall). Then you have easy access to the bulbs. Good luck.
I had the exact same problem. To solve it, I had a friend hold the area
of the fan that the globe screws into. I wore rubber dish gloves to get
a good grip and pushed up slightly on the globe as I turned
counter-clockwise. My friend held the other part and turned clockwise a
little as well. It took a lot of pressure for it to finally come loose
and then we just turned it about another 90 degrees and the globe slips
right out of the groove.
I couldn't believe how hard this was to do.
At the top of the pull chain there is a metal piece; this is threaded on a bolt. Unscrew the metal piece and lower the globe to expose the bulbs then remove and replace the bulb(s). I recommend flourescents as they are more economical, run cooler and last linger than incandescents (regular bulbs).
