I like the hand primer. I get a better feel of when they are set right with the hand tool instead of the press. But some cases (Mainly Winchester 7.62X54R cases) need just a littler more force to get them primed. Then I break out the Lee Ram Primer and do use the press. (Why the Winchester cases have such tight primer pockets I have no clue!)
Anyways for a manual you can use the Auto Prime XR manual I would guess Like was previously mentioned I think the only difference is the little thingie that lifts the next primer up to feed and would probably stop a chain reaction detonation, which I have never had happen in 35+ years of hand priming.
Anyways the instruction sheet for the XR can be downloaded for free at :
