Probably good advice. The question about a pneumatic Saws-all is air
supply. A moderate size portable tank will probably give you less run time
than the batteries. You will need a gasoline powered air compressor. Or,
how about putting two 12v car batteries in series, and cobbling up a
connection to your electric saw?
