Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.
It’s a blender… As long as it’s unplugged you’ll be fine.
I think the concern is that you would re-assemble it with the safety bypassed, not that you would harm yourself while disassembling the appliance.
PLUG IT IN UNDER WATER!
Well your blender problems would be over at least.
Seriously. I’m not sure why people think it’s so dangerous. Unplug it and remove the blades. Its just a motor for God’s sake
