:rofl: Ash m8, if I meant which side of line I would have said that! Ok so I'm gonna assume then that whilst holding it in your RIGHT hand, the BLADE is on left of the grinder, yes?
Ok so this means all the dust and crap is forced toward u! Yes? And if it bites and snags in the tile it will be pulled from your hands and could end up in or on someone or something else!!
Now if u spin your guard (if u use one!) thro 180 so that it's kinda upside down. Not only will all the dust be pushed away from u, if it snags it'll come toward u! It might sound more dangerous but in my experience it's safer because you're already holding it tightly so as it comes toward u u'll find u naturally use your arms as a damper and u remain in control! I know some will disagree with this but this what I find safest and cleanest for me! Give it a go.
