No, don't speak Chinese, but did work in Taiwan, China and Japan over a 20 year period. How did I come up with it? I don't like things that don't work properly and I don't own anything that I haven't taken apart at least once.
Hope my solution works for others - another tip, put a drop of Loctite Thread Lock on the free spool release button - then you won't be searching in the snow for it.
