Open the black caps - holding tanks

Hi everybody.

I've just past more than one our reading yours awesome messages but I can't find the answer for my question. How the black caps on the deck comes out? (to aspirate the contents of the holding tanks or fill them with bleach) I have to unscrew them? I've tried with the stem of an Allen wrench but I'm scared to be too hard and break something...


Thanks a lot.
