Invert electric motor rotation
Single phase, permanent-split-capacitor (capacitor run) motors, like your unit, are normally reversed by switching the roles of the start and run windings.  Unfortunately, with the way your unit is wired, it is not possible to make the necessary wiring changes without completely disassembling the motor -- you would have to disconnect the two red wires from each other, then connect the red wire from inside the motor to the terminal that now has the tan wire from the motor on it while connecting the red wire from the capacitor and the tan wire from the motor together, then taking them to where the red wire from the motor now leads.

So, you'll have to head down to a shop that sells motors (industrial-supply places will have them, guaranteed) and get a new motor to power your saw with; either that, or find a way to make your saw work with a motor that rotates the opposite direction from the original.
