7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slicer does not turn on. | Not plugged in; power switch off; child lock engaged. | Check power connection; ensure switch is on; disengage child lock. |
| Blade gets stuck or slows down. | Slicing hard food (e.g., bread crusts); food item too large; motor overheating. | Reduce pressure; cut food into smaller pieces; allow motor to cool down for a few minutes. |
