I have just posted in another thread on the subject but I will copy that post here as I have found the solution:

I removed the screw (top bit with two tiny holes) and took off the lever mechanism (remember the order in which the parts came off!) and sprayed on a very tiny amount of Servisol contact cleaner. This is sold as a switch cleaning lubricant so I assume I will not need to add any lubricant later (although if I do, it's not a problem).

The wind on lever is now as silky smooth as it was when I bought the camera.
I read about the idea of cleaning up under the wind mechanism on another forum - might have been Photo.Net
