Turn the flywheel (7) whilst pressing the "X" button and perform about 20/30 blade revolutions; stop rotation
and check against the light that a slight burr has formed on the blade edge; turn the flywheel (7) again whilst
pressing the "K" button and perform 1 or 2 blade revolutions; for safety reasons do not exceed 1 or 2 blade
revolutions in order to prevent the blade edge from springing back. Return the sharpener to its original
position.
