Ingredient Preparation:
- Wash all fruits and vegetables thoroughly.
- Peel fruits with thick skins (e.g., oranges, lemons, pineapples).
- Remove hard pits or seeds from fruits (e.g., peaches, cherries, mangoes).
- Cut ingredients into pieces small enough to fit into the 3-inch feed chute.
- For leafy greens, roll them into a tight ball before feeding.

Using Soft/Hard Modes:

- Plug in the juicer.
- Turn the control dial to the appropriate setting:
- "Soft" Mode: Ideal for softer fruits and vegetables like celery, watermelon, oranges, spinach, and berries.
- "Hard" Mode: Suitable for harder ingredients such as apples, carrots, ginger, and kale.
- Slowly feed prepared ingredients into the feed chute. Use the food pusher only if necessary and with gentle pressure.
- Allow the juicer to process the ingredients completely. Do not overload the machine.
- Once juicing is complete, turn the control dial to "0" (OFF) and unplug the appliance.
Reverse Function (Rev):
If ingredients become jammed or stuck during juicing, use the Reverse function to clear the blockage.
- Turn the control dial to "0" (OFF).
- Turn the dial to "Rev" and hold for a few seconds. This will rotate the auger in reverse to dislodge food.
- Release the dial to return to "0".
- If the blockage persists, repeat the process or disassemble and clean the juicing chamber.
Cleaning and Maintenance
Regular cleaning ensures optimal performance and extends the life of your juicer. All detachable parts are dishwasher safe.
