UPDATE!
Carefully lift it up (don't flip it), at the buttom there maybe is some screws (3 or 4) that has to be tightened!
The pickup you can flip down the little acrylic plate and give the tonearm support by some foamblock.
Furthermore you can liftoff the turntable platter (on this model the transport screws alternatively can be placed under the platter) so it won't damage anything if you accidently flip the player upside down :-)
