7. Maintenance
7.1 Blade Sharpening
The built-in sharpener ensures your blade remains optimally sharp. Sharpening should be done periodically, or when you notice a decrease in slicing performance.

- Sharpening: Turn on the slicer. Gently press the blade against the sharpening stone for 10-15 seconds.
- Trimming: After sharpening, gently press the blade against the trimming stone for 2-3 seconds to remove any burrs.
- Return Sharpener: Turn off the slicer and return the sharpener to its resting position.
7.2 Lubrication
Periodically lubricate the sliding rod of the food plate with food-grade lubricant to ensure smooth operation.

8. Troubleshooting
If you encounter issues with your Berkel Red Line 250, consider the following common solutions:
- Slicer Not Turning On: Check if the power cord is securely plugged into a working outlet. Ensure the ON/OFF switch is correctly pressed. Verify that the food plate is properly installed and the CE Block is engaged.
- Uneven Slices: Ensure the food item is firmly secured by the product press holder. The blade may need sharpening. Check that the thickness adjustment knob is set correctly and not loose.
- Difficulty Slicing: The blade might be dull and require sharpening. Ensure the food item is not too hard or frozen. Apply appropriate pressure with the product press holder.
- Unusual Noise: Turn off and unplug the slicer immediately. Inspect for any foreign objects or loose parts. If the noise persists, contact customer support.
- Food Sticking to Blade: Ensure the blade is clean and free of residue. For certain foods, a light application of food-grade spray on the blade may help.
