Phenom Setup - What do I do with the 4 screws?

Hi,
I couldn’t find in the user guide what the 4 SHCS with the hex keys are for. Any ideas?

Thanks.

the hex screw driver is for the 4 screws under the vat holder, it’s used in leveling with standard vat : https://wiki.peopoly.net/doku.php?id=moai:leveling&s[]=leveling
