I honestly can't remember. but if you jack up the wheel and turn it while turning the adjuster you will evenutally not be able to turn the wheel. Assuming your shoes aren't totally worn (and aren't isntalled backwards). If it doesn't stop turning, turn the adjuster the other direction.
One caveat, there is a stop, like a little shoulder, on the adjuster, that will stop you from turing it too far. Don't force it past that.
Alternatively, just pull the hub and look at the adjuster.
