No. The code does not require a neutral on 240 circuits. What was changes was electric ranges and cook tops and ovens. In the past, these items bonded the neutral to ground at the device and combined neut and gnd. That is what changed to require a neutral with a 240 v circuit. The saw only requires 240 and a ground, but no neutral. And if powered by 120 v, the saw is required to be GFCI protected, as are all other 120 v circuits in a garage or shop. So bottom line is, change to 240 operation.
