I would say in picture 2, you can see the hook holding the band is standing way off, so its that gear...maybe 1st? I have a feeling it cannot be top gear as all bands are engaged in that gear?
I may be totally wrong on both counts, and be banned from the forum for talking rubbish....goodnight!!
I have to admit, I always toggled the gears in mine, and made sure it was in neutral before starting...surely you would have smelt something (not you...whoever left it running)!!!
