Hello,
There is this mysterious label on my Dyson handheld vacuum cleaner (see below). What does it tell me? My guess is that I'm not supposed to press the button with my index finger, but with my thumb. That would make sense because the thumb is stronger for continuous pressing. According to the picture, I should slide four fingers under the handle. But I can only fit three fingers through. And then it's not possible to operate the button with the thumb without injury. The picture also shows that the thumb is now not on the button. So: how is it meant?
Best Regards,
Ralph
