Use:
1. Opener is removed from storage place and placed in position on top of can.
2. Button is held until opener begins to move.
3. Let go and wait for opener to finish.
- If the can is larger than a standard soup can multiple cycles must be used.
4. Lift the opener off of the can.

Functional Operation:
1. Opener is positioned on can, which presses a safety switch.
2. Button on top is pressed to close main circuit using manual switch.
3. Motor engages and turns several gears to drive movement wheel and move the cutting wheel into position.
- There are four gears used to gear down the movement wheel, with a fifth gear to further slow the cutting wheel.
4. As cutting wheel gets into position, the main circuit is closed using an automatic switch that is pressed by the top of the cutting wheel shaft.
5. The cutting wheel is even further geared down using a secondary portion to its gear. This allows it to rotate roughly ten degrees about six times through the cutting process.
6. When the cycle is nearly completed the cutting wheel is retracted again and the automatic switch is released, stopping the opener.
7. A magnet on the underside of the opener lifts the top of the can with it when the opener is lifted off.
