The adjustment is accomplished by changing the position of the blades
in the arbor. There should (I haven't seen this particular machine) be
some leveling screws or equivalent means of controlling how much blade
exposure you have. These are used to make each blade (they needn't be
exactly the same size, particularly after being sharpened) take exactly
the same cut, parallel with the table.
You shouldn't expect a tool to be properly adjusted as it arrives from
the manufacturer. (Well perhaps you should, but don't expect it :-)
Power tools are often only casually adjusted, and hand tools such as
planes and chisels aren't really sharp. Part of a craftsman's skill is
in the care and tuning of his tools.
