The lever is lifted, and the edge of a can is placed between the feed gear and cutter. A magnet grips the top of the can.

When pressed down, the lever activates a switch that turns the motor on. The motor passes power through gears to turn the small feed gear and rotate the can. As it is rotated, the cutter cuts through the edge of the lid. When the can is removed, the lid stays attached to the magnet.
