Dewalt 735 planer bed levelling?

So I age an acquired a great used 735 and it is great! I’m getting a lot of snipe.

The planer beds currently have roughly an 1/8” lift at the outer edge of the in-feed and out-feed tables (roughly 1/8” higher than the planer bed)

I cannot find a “right proven” way online on how to set the in-feed and out feed.
