To operate the CO600, hold the can under the guide pin & press the lever lightly & the self-starting blade will pierce it & commence cutting. The can remains fixed in position with the magnet resting against the lid until the can is open, when the motor will automatically stop while retaining the can & lid safely in place. The Kenwood CO600 has non-slip feet & the blade can be removed for easy cleaning. It is a three-in-one tool that also features a bottle opener & knife sharpener, could be useful for time savers & those who have difficulty working a manual can opener.
