Lubricating the trem on a DGT

[H2-DGT]

Dumb question, but the Setup page suggest "If the guitar is returning sharp after using the tremolo arm, put a little lightweight machine oil under the head of each screw (do not loosen the screws). This will effectively oil the knife-edge of the tremolo."

Are they referring to the screws on the top of the trem (in-between the treble pickup and saddles)? Or inside the trem cavity?

Thanks!
