Food is unevenly chopped:

Either you are chopping too much food at one time, or the pieces are not small enough. Try cutting the food into smaller pieces of even size, and processing smaller amounts per batch.

Food is chopped too fine or is too watery:

The food has been over-processed. Use brief pulses or process for shorter time. Let blades stop completely between pulses.

Can the blades be sharpened?

No, never try to sharpen blades!

Cannot achieve snow from ice.

Do not use ice that has been sitting out or has started to melt. For best results use ice straight from the freezer.
