5. Operating Instructions
5.1 Ingredient Preparation
- Wash all fruits and vegetables thoroughly.
- Remove large seeds, pits, and hard skins (e.g., pineapple, melon, citrus).
- Cut ingredients into small pieces (approximately 1-inch cubes) to fit the feed chute and prevent blockages.
- For fibrous vegetables like celery, cut them into short segments.

5.2 Juicing Process
- Ensure the juicer is correctly assembled and the juice jug and pulp container are in place.
- Plug the power cord into a suitable electrical outlet.
- Turn on the juicer.
- Slowly feed the prepared ingredients into the feed chute. Use the food pusher to gently guide them down. Do not force ingredients.
- The juicer will automatically separate the juice and pulp into their respective containers.
- The juicer is designed for continuous operation for up to 20 minutes, after which it will automatically stop to prevent overheating. Allow it to cool down before resuming operation.
5.3 Reverse Function
If ingredients become jammed or the juicer stops during operation, use the reverse function:
- Turn off the juicer.
- Press and hold the "Reverse" button (if available, or switch to reverse mode). This will rotate the auger in the opposite direction to clear blockages.
- Release the button, then switch back to the "On" position to resume juicing.
- If the blockage persists, disassemble the juicer and clear the obstruction manually.
