Common questions about manuals, registration, and support for this brand.
You can hand wash the slicer using the enclosed detail brush to ensure safety around the blades. Alternatively, the unit is dishwasher safe (top rack recommended). Ensure it is dried thoroughly before folding and storing.
The slicer is designed for most vegetables and fruits such as potatoes, onions, tomatoes, cucumbers, carrots, and zucchinis. Avoid cutting ingredients that are extremely hard, contain bones, or are too soft and juicy.
If you encounter resistance, try reducing the force used on the pusher. Forcing ingredients too hard can jam the blade; a steady, moderate motion usually works best. Also ensure larger vegetables are cut to a suitable size to fit the chute.
Pigments from vegetables like carrots or purple cabbage may stain the plastic. It is recommended to clean the unit immediately after use. If staining occurs, wiping the area with cooking oil can help remove the discoloration.
