I have been cutting some slabs and found that by rotating the guard on
my 230mm grinder, I could use it 2 ways:

1. 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.

2. 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?
