I recently bought a 2006 Grass Eco Press Hinge Borer and I can't for the life of me figure out how to adjust the depth of drilling. Would anyone know how this is done?

On my hettich and gannomat hinge borers there is a threaded rod next to the cylinder with a pair of nurled nuts that function as travel stops.

I got speaking to an engineer from Grass and I got it sorted. There's two stops in front of the drill bit that if you adjust them they'll raise the bit up and down, in case anyway buys one and was as baffled as I was.
