Can't remember the one I use but the manual says 9/16" UNF on axle. Probably 22-24mm socket? It will not be tight, when you pull the pin and remove the castellated washer it should undo with fingers.
The tightening torque is listed as 5lbft then unscrew 1 flat and fit the split pin. I generally tighten a bit with the socket wrench, not too hard but enough to take out all the slack, the loosen and tighten again (without touching the hub) using the extension bar only (no wrench). Put the wheel back and it should spin with very slight play if rocked top and bottom.
