I have been cutting some slabs and found that by rotating the guard on my 230mm grinder, I could use it 2 ways:
- Blade spins towards you.
In this method, the the dust fires AWAY from you, BUT if/when the grinder kicks, it will come towards you.
- Blad spins away from you
Now you get the dust firing in to your leg, but grinder would now 'kick' away from you!.
I am guessing that the 2nd of these is the safest, but which is correct?
