Start from nothing and advance, never the other way round
Setting the depth
Retract the blade until it does not cut at all. Advance in tiny increments, testing on the wood, until a shaving just appears.
Lateral adjustment
Sight down the sole from the front. The blade should show as an even hairline. Correct with the lever before touching the depth again.
What a good shaving looks like
Translucent, full width, and continuous. If it is thick or breaks up, back off rather than pushing harder.
