The silence here in response to that is slightly unnerving...
This is what outlets and plugs look like in the United States.
Both run on 120 V at 60 Hz.
The internet informs me that power in Brazil sometimes comes through the same plug shapes (but also some others) and runs at 60Hz. However, the internet also informs me that it runs at 127 V and 220 V or sometimes at 115V. I am not entirely sure what the outcome will be if you plug your 220V saw into a 120V outlet but I'm pretty sure you won't like it.
You may want to investigate this further.
