Reply to loose jog wheel

i got my vci-100 about a week ago and noticed right off the bat that the left jog wheel is a bit loose. for instance, if i put pressure on the outside ring it jiggle up on one side and down on the side im putting pressure on.

but i was wondering will i have to take the whole thing apart to tighten this or will the top 3 screws do the trick? if not what will..?
