When it is spread out like that - lift the top off.
It kind of "sticks", but it was the same here by me, a bit hard to get off.
Klaus, I don't believe it - it  worked.  Incredible!  I would never have figured this out for myself.  I immediately did an interior lube service on the model.  I also noted the method to open the model in Win-Digi-Pet for future reference.  WDP tells me the model has 60.5 total running hours on it, so not too bad really for a model with a specified lubrication interval of 40 hours.  You have saved my model.  I owe you a beer!  (Just one little aside: this model has always rocked (in German: rueckelt) a little when moving, and it still does.  Does yours also?)

And I think I owe David an apology for somewhat hijacking his thread, but I am oh so happy with the outcome.  Sorry David!

Cheers
Tom
