its no big deal to get acces to the bottle in the Hannibalitos. But Im not the one whos going to put my hand 8cm deep in a robot when free and unrestricted acces in available from below.

And if were talking heavies, its not that easy to lift it, turn open the bottlevalve and put it down in a safe fashion.

And, more rules, more regulations, more laws please do.... Especialy concerning the already overregulated pneumatics section.
