5. Operating Your Juicer

Follow these steps for safe and effective juicing:

1. Preparation: Wash fruits and vegetables thoroughly. Most fruits and vegetables do not need to be peeled, but citrus fruits should be peeled before juicing. Remove large seeds or pits from fruits like peaches, cherries, or plums. Cut larger items into pieces that fit easily into the feed chute.
2. Power On: Plug the juicer into a standard electrical outlet. Turn the single-speed control dial to the 'ON' position.
3. Juicing: With the motor running, place prepared fruit or vegetable pieces into the feed chute. Use the food pusher to gently guide the food down. Do not force food into the chute, as this can damage the motor or reduce juice yield.
4. Collection: The extracted juice will flow through the angled spout into the 20-ounce jar. Pulp will collect in the pulp collector container.
5. Completion: Once juicing is complete, turn the control dial to the 'OFF' position and unplug the appliance.

Tips for Best Results:

• For maximum juice extraction, feed ingredients slowly and steadily.
• Juice harder fruits and vegetables (like carrots or apples) before softer ones (like berries or leafy greens) to help clear the filter.
• Empty the pulp collector and juice jar as needed during extended juicing sessions.

6. Care and Cleaning

Regular cleaning ensures optimal performance and extends the life of your juicer. All removable parts are dishwasher safe.

1. Disassembly: Ensure the juicer is unplugged. Release the locking arm and remove the juicer cover, filter basket, pulp collector, and food pusher.
2. Rinsing: Rinse all removable parts under running water immediately after use to prevent pulp from drying and sticking.
3. Washing: Wash removable parts in warm, soapy water using a brush for the stainless steel filter basket to remove any trapped pulp. Alternatively, place them on the top rack of your dishwasher.
4. Motor Base: Wipe the motor base with a damp cloth. Never immerse the motor base in water or any other liquid.
5. Drying and Storage: Dry all parts thoroughly before reassembling or storing. Store the juicer in a clean, dry place.

7. Troubleshooting

If you encounter issues with your juicer, refer to the following common problems and solutions:

• Juicer does not turn on:
  • Ensure the power cord is securely plugged into a working outlet.
  • Verify that the locking arm is fully engaged and secured over the juicer cover. The juicer has a safety interlock system.
• Low juice yield or excessive wet pulp:
  • The stainless steel filter basket may be clogged. Turn off and unplug the juicer, then clean the filter.
  • Food may be fed too quickly. Feed ingredients slowly and steadily.
  • Some fruits and vegetables naturally yield less juice.
• Motor stops during operation:
  • The juicer may be overloaded. Turn off and unplug the appliance. Remove any lodged food and allow the motor to cool for 15-20 minutes before restarting.
  • Check if the pulp collector is full and empty it if necessary.
• Vibration or excessive noise:
  • Ensure all parts are correctly assembled and the locking arm is securely fastened.
  • The juicer should be on a flat, stable surface.
