Elliot,
On the breather it is mentioned in the German instructions I received with the excavator...

I did receive an English tranlsation via e-mail which states in part:
5th Transport lock
Thus, the model may lose no oil during transport, was an M5 screw Phillips in the filler neck of the tank is screwed. Replace them before using with the supplied allen screw M5 with a central hole from. The central Hole serves as an operational model for the tank vent.
On the bottom right of the 2nd page there is a picture of the cap head bolt.
Did you see the Quick release that one of the German guys had modified? With two coils pulling the pins out of the road? That is what I was thinking of... Just have to find the link... again...
Cheers,
Andrew P.
