The paper shredder I bought so many years ago. Finally gave up, today. Didn't have the power to do much more than growl at me.
Took the screws out of the bottom, and took the cover apart. The lubricating grease on the gears had dried out. Took it outside, rinsed off the gears with ether starting spray. Relube with good brand of silicone.
The sticker said it was made in 2001.
Try it with some paper, and it's best it's been, in years.
