8. Troubleshooting
If you encounter issues with your Mueller Mandoline Slicer, consider the following common solutions:
- Food not cutting cleanly: Ensure the blades are clean and free of debris. Verify that the food item is fresh and firm enough for slicing/chopping. Avoid overfilling the chopper.
- Difficulty closing the chopping lid: Ensure the food item is cut to an appropriate size and centered on the blade grid. Do not force the lid down; this can damage the blades or the unit.
- Blades appear dull: While the stainless steel blades are designed for durability, continuous use on very hard vegetables may affect sharpness over time. Ensure proper cleaning and storage to maintain blade integrity.
- Unit not stable during use: Always place the unit on a dry, flat, and stable countertop.
