Chris is right. If the saw will run without one on 110, it will also
do it on 220. My saw came with the option of either also and was just
a minor wire change on the motor and that was 20 years ago. Specific
instructions included.

You get more power from any motor running it at 240 (220).

Faster starting, less likely to bog down. Same operating cost. Smaller wire
size. A few Delta saws have a different set of windings and you get 2 HP
instead of 1.5

Separate circuit is always a plus. When I first go my saw I wanted to try
it out before hte new line was installed. I hit the switch and the
fluorescent lights went out for maybe 5 seconds until the saw got up to
speed. Scary. Next day I ran the new line. .

Yeah, but only scary in the Adaams family kind of way.

How much of this you'll actually see varies greatly. If the wire length from
the panel is short (<50') and you're not close to the limit on
the circuit, the differences will not be noticable. You're seldom able
to take advantage of a smaller wire size.

Yup, separate is always a plus.
