The European models of the Polysix all had pre-installed 3-wire power cords.
The service manual also gives only schematics for two different 3-wire setups.
But in general: having voltage against ground on the chassis is a bad
thing, regardless if the problem goes away with a grounded plug. This
should be fixed at the root of the problem.
