4. Operation
Operating your ritter E 16 Duo Plus slicer is straightforward:
- Select Blade: Choose the appropriate blade for your food item. Use the serrated blade for bread, hard cheeses, or vegetables. Use the smooth blade for ham, cold cuts, or softer cheeses.
- Adjust Slice Thickness: Turn the slice thickness adjustment knob to your desired thickness, from very thin to approximately 20 mm.
- Position Food: Place the food item firmly against the food carriage and the slice thickness guide. Use the food holder to secure smaller items and protect your fingers.
- Activate Slicer: Use the safety switch to turn on the slicer. You can choose between:
- Momentary Operation: Press and hold the switch for continuous slicing as long as it's held.
- Continuous Operation: Engage the switch for continuous operation without holding. Remember the 5-minute maximum continuous operation time.
- Slice Food: Gently push the food carriage towards the rotating blade. The inclined design helps guide the sliced food onto the collection tray.
- Deactivate Slicer: Once slicing is complete, release or disengage the safety switch and wait for the blade to stop completely before removing food or cleaning.
