Well let us know how it works.   

Hopefully they figure it out with the manuals sent.  So far no joy I guess.

Think I found something on it.

I don't read Chinese (or patent language), but the drawings (more after page 34 in second patent document listed) are helpful.  There are clearly some similar concepts, but these show a flat sharpening platten / surface, versus a round one, and a gear driven grinding head, versus a gravity fed one.

This patent may have been a precursor in the development?  But compare those drawings to the cut away photos and IPLs in the Temco thread.

Philbert I had deleted 2 of your post and one of mine to clean up the thread on the weird links. No clue where the one went with the link you were asking about after I fixed link for ya. But here it is again with working link.  http://chainsawrepair.createaforum.com/chain/automatic-chain-sharpener-under-$300/
