Standing Grizzly on Tail ?

I see a number of picture where owners are pulling up the front to access the bottom of the machine to service , like washing. I like the idea. The older i get, it get harder to get down on the floor and roll around. My question is there any issues with the fluids in the machine being at those angles ? Talked a mech at a dealer and he said he stands his on end all the time . I can see maybe not quite a 90 degree angle like Pohlhammer posted a pick. What do you all think? Any issues arise from doing this ? I know saftey first:gcrules::gcrules:
