I just got to test mine for the first time today.

The problem is it doesn`t spin on Speed #1 and #1.5. It just produces a whirring sound.

I`m not sure if the issue is with my step-down transformer or if the tool is defective. It works though when I set it at #2 and #3 (I haven`t tried higher speeds).

Here`s a video of the polisher as I try to turn it on: https://youtu.be/DNQMD7qM81o

As an additional information, the step-down transformer I`m using is rated at 3000-VA.
