7. Troubleshooting
If you encounter any issues with your mandoline slicer, please refer to the following common concerns:
- Difficulty Slicing/Requires Much Pressure: Ensure the ingredient is properly positioned in the chute and that the thickness setting is appropriate for the food item. Some denser vegetables may require more force.
- Flimsy Plastic Chute/Box: While designed for durability, avoid excessive force or dropping the unit, which could damage plastic components. Handle with care during use and cleaning.
- Uneven Cuts: Ensure the ingredient is held firmly by the food pusher and guided consistently through the blade. Irregularly shaped items may yield less uniform results.
- Food Sticking: Ensure the blade is clean and free of debris. For starchy vegetables like potatoes, rinsing the blade periodically during use can help.
If problems persist, please contact customer support.
