4. Setup

Before first use, ensure all packaging materials are removed and the grinder is placed on a stable, flat, non-slip surface. Verify that all components are present and undamaged.

4.1 Initial Cleaning

Wipe the grinding chamber and exterior with a damp cloth. Do not immerse the main unit in water. Ensure all parts are dry before assembly and use.

4.2 Preparing for Grinding

• Ensure the power cord is accessible but not obstructing the grinder's operation.
• Confirm the lid is properly aligned and the safety lock mechanism is ready for engagement.

5. Operating Instructions

Follow these steps for safe and effective grinding:

1. Prepare Material: Ensure the material to be ground is completely dry. Break larger pieces into smaller, manageable sizes if necessary.
2. Load Material: Open the lid and carefully pour the material into the grinding chamber. Ensure the material covers the long blade and does not exceed 2/3 of the jar's capacity.
3. Secure Lid: Close the lid securely. Rotate the lid to slot the rod into the groove and lock it. Press down the locks on both sides of the lid until you hear a click, ensuring it is properly fastened.

5. Start Grinding: Turn the power switch to the "ON" position. The grinder will start operating for the set time.
6. Monitor Process: Observe the grinding process. If the desired fineness is not achieved, you may run another short cycle after allowing the motor to rest.
7. Finish Grinding: Once the grinding cycle is complete, turn the power switch to "OFF" and unplug the unit.
8. Remove Powder: Carefully open the lid. Pour out the ground powder. Use the provided cleaning brush to remove any remaining residue from the chamber.

7.2 Frequently Asked Questions (FAQ)

Figure 7.2: A visual representation of common questions and their answers regarding the grinder's operation and maintenance.

Q1: Why does the grinder not work?

A1: First, check if the indicator light is on. If not, ensure the power supply is plugged in securely and inspect the power cable for damage. If the light is on, verify whether the carbon brush is faulty. If both are normal, check if the timer starts properly.

Q2: Can it grind coffee beans?

A2: Yes, but only dry materials like rice, corn, nuts, or dried chilies. Not suitable for moist, oily, or sticky items.

Q3: What should I do after receiving the product?

A3: First check for damage and ensure all accessories are included. Then verify the timer is set correctly.

Q4: How do I clean the machine?

A4: Always unplug before cleaning. Wipe with a dry cloth only – do not rinse with water or use abrasive tools.

Q5: Is the strong smell during first use normal?

A5: Yes, this is normal for new machines. Simply wipe the container with a dry cloth and grind some rice or tea first to remove the odor. Any slight sparks or smell during initial use are caused by the brush motor's normal friction and will disappear after the first few uses.

Q6: How do I replace the carbon brushes?

A6: Unscrew the nut counterclockwise, remove the old brush, insert the new one, and tighten the nut securely. (Note: This answer from the image seems to be simplified. Refer to Section 6.3 for detailed steps.)

Q7: How do I remove the blade?

A7: Secure the screw under the shredding chamber first, then use a wrench to unscrew the nut counterclockwise. (Note: Refer to Section 6.2 for detailed steps.)

Q8: What if I see sparks and smoke?

A8: Check if the container is over 2/3 full or used beyond 3 minutes. If persists, inspect and tighten carbon brushes before restarting.
