Does anyone here know the location of reverse/forward switch on a Hampton Bay 60" industrial 3 blade fan?

I don't believe they are reversible. Why do you need to reverse it?

Generally in the winter I would want to circulate the warm air off the ceiling. The instruction manual says you can do this with the forward/reverse switch.

If there is one I presume it would be on the lower canopy, right on top of the motor. But I don't think this particular fan is reversible.

You can circulate the warm air off the ceiling by running the fan on low in either direction. See:

I found the switch by accident. It was under the "bell" shaped cover that is over the coupler area. I don't know why they can't explain things more clearly in the manuals.
Poor manuals are a big reason why people don't read them in the first place.

I'm interested to know that they do have a reverse feature in these fans. It's not listened on any of the specifications, and frankly those specially curved blades won't do much good in reverse.
