need wiring diagram for hakko 851-2

[jparker708]

I have a hakko 851-2 that I can not figure out how to reconnect  or find any documentation  on how to wire the air pump and the heat gun back up. I have contacted hakko they  said the schematic  and wiring diagram are proprietary.  So if anyone has this unit can send me a picture or a guide on how to reconnect  so greatly appreciated!!

The board seems to have some markings: https://hakkousa.com/b1218.html

In the last seconds of this video it is somewhat visible. It is not much but maybe just enough to help.
