Loose Toilet seat on a Roca close coupled bowl?

Hi,


I have a Roca close coupled toilet and the seat is loose......


I've had a look at it and the bolts attaching the seat to the bowl are enclosed within the unit. I can't see how I'm supposed to tighten them without taking the whole unit off the wall.....





Any ideas / advice gratefully accepted!
