Safety Information
Your safety is paramount when using any kitchen cutting tool. The ONCE FOR ALL Mandoline Slicer is designed with a hidden blade mechanism to minimize direct contact with sharp edges. Always adhere to the following safety guidelines:
- Keep Fingers Clear: The design ensures your fingers do not touch the blades during operation. Always use the integrated food feeder and press handle to push food through.
- Stable Placement: Ensure the slicer is placed on a clean, dry, and stable surface. The six strong suction cups at the base must be engaged to prevent movement during use.
- Adult Supervision: Keep out of reach of children. Adult supervision is required if children are present in the kitchen area during use.
- Inspect Before Use: Before each use, inspect the slicer for any damage or loose parts. Do not use if any components are broken or compromised.
- Cleaning Safety: Exercise caution when cleaning. Use the provided cleaning brush to remove food residues and avoid direct hand contact with the blades.

Maintenance and Cleaning
Proper maintenance and cleaning will extend the life of your slicer and ensure hygienic use.
- Immediate Cleaning: Clean the slicer immediately after each use to prevent food residues from drying and hardening.

- Dishwasher Safe: The slicer is dishwasher safe. Place it on the top rack. However, for optimal cleanliness and to address potential food traps, manual cleaning with the brush is recommended for hard-to-reach areas.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slicer moves during operation. | Suction cups not properly engaged or surface is not clean/dry. | Ensure the countertop surface is clean and dry. Press down firmly on the slicer to activate the suction cups. Wiping the suction cups and counter with a damp cloth and drying them can improve suction. |
| Food gets stuck in crevices during cleaning. | Residues are drying or hard-to-reach areas are not being cleaned effectively. | Clean immediately after use. Utilize the provided small cleaning brush to reach all crevices and blade areas. For stubborn residues, soak the slicer in warm, soapy water before cleaning. |
| Difficulty slicing certain foods. | Food item is too large, too soft, or not positioned correctly. | Ensure food items fit comfortably in the feeder. For very soft foods, chilling them slightly may help. Ensure consistent and firm pressure on the press handle. |
