The section on setting the slop (33-300) says "Place tester on front
wheel hub and set dial guage to approx. 2mm preload" but then it says
under Data "Wheel bearing end play 0.01-0.02" with no units

The "2mm preload" is there to make sure the dial indicator is not near
the end of its travel and will indicate the bearing free-play properly.
You put the dial indicator mounting hardware on such that the dial
indicator moves 2 mm from its rest position when it is in place.

Once the dial indicator has moved the 2 mm from its rest position, you
move the hub/disk in and out to see how much free play there is in the
wheel bearing. The free play should be 0.01 to 0.02 mm (0.0004 to 0.0008
inch).

Can also rap the wheel as you tighten.  The resonance will change when its
right.  Put a dial indicator on it and should be spot on.

Not mine.  I seldom need to touch wheel bearings.  when I do I just 
do it by feel  tighten until the bearing gets snug, then back out the 
nut 1/3 turn and clamp it down.  May be too loose, but it is ok for 
off track normal driving.  No dial indicator needed.  I've done it 
that way for 40 years.   My dad taught me to do merkin iron by feel. 
I just applied it to MB tolerances.
