Opened up the body of the polisher and replaced the defective switch. Quick easy repair. Used the surgical clamp to grip the 3 wires and pull them from the switch.

Parts Used
Researched common failures on Google and found the speed control switch was a common fail.
Removed screws in the tools handle exposing the speed control switch
Removed the three wires by tugging them out with pliers while noting their order in the old switch
Reinserted the wires in the same order using pliers to ensure they were firmly inserted into the new switch
Reassembled the handle and screws
Plugged the polisher in and have it a try at all speed settings and it worked like new.
