Hey, I've done something else!
I was using a blower-vac outside to pick up leaves and stuff after mulching some garden refuse.
Under the compost bin (where the stuff went) was hiding a large black plastic bag.
The 2400W blower vac sucked the bag up with more gusto that I've seen it employ against anything else before.
Then I hear a nasty sound (stalled motor).
Even though my finger was a matter of cm from the power switch it really took me a couple of seconds to react and I pulled out the power cord.
The blower-vac smelt very much like the smell you don't want to smell from a motor or transformer.
As I was dissasembling it the area around the motor was getting warmer (clearly it took a while for that heat to escape the windings
About 30 screws later I cracked it open revealing a very hot motor (still about 60C I estimate) and a black plastic bag completely encasing the impeller.
Put it back together after removing the bag and it still works.
I don't want to find out how many seconds is required to toast the motor, so I'll keep well away from plastic bags in the future!
It was almost doubly disappointing because I was planning to spend about $90 on one of these when my wife found the "shop soiled demo" going for $30. After getting it for such a good price it would kill me to have to buy another at full price!
