Important Note: This grinder is specifically designed for dry materials only. Do not attempt to grind wet, fresh, oily, or sticky substances, as this can damage the machine and void the warranty. Ensure all materials are completely dry before grinding.

2. Safety Instructions

Your safety is paramount. Please adhere to the following safety guidelines:

• Open-Cover-Stop Protection: The grinder is equipped with a safety device. If the lid is opened during operation, the machine will immediately stop to prevent injury. Ensure the lid is securely closed before starting.
• Overload Protection: In case of overload or overheating, the machine may stop functioning. This is a safety feature. Refer to the troubleshooting section for resolution.
• Dry Materials Only: Only grind dry materials. Wet or oily substances are not suitable and can cause damage.
• Recommended Capacity: Do not overfill. The material to be ground should cover the long blade in the middle and not exceed 2/3 of the tank capacity. This allows sufficient space for proper grinding circulation.
• Operating Time: Do not operate continuously for more than 3 minutes. Allow the machine to rest for 5 to 10 minutes after every 3 minutes of operation to prevent overheating and motor damage.
• Electrical Safety: Ensure the power supply matches the grinder's voltage (220V). Do not operate with wet hands or in wet environments.

4. Setup

Before first use, follow these steps:

1. Unpack: Carefully remove all components from the packaging.
2. Placement: Place the grinder on a stable, dry, and level surface. Ensure there is adequate ventilation around the unit.
3. Initial Cleaning: Wipe the interior of the grinding chamber with a dry cloth to remove any manufacturing residue.
4. Lid Check: Ensure the lid is properly aligned and securely closed. The safety mechanism requires the lid to be fully engaged for the grinder to operate.
5. Power Connection: Plug the power cord into a suitable 220V electrical outlet.

5. Operating Instructions

Follow these steps for grinding materials:

1. Prepare Materials: Ensure your materials are completely dry. Break larger pieces into smaller, manageable sizes if necessary.
2. Load Materials: Open the lid and carefully place the dry material into the grinding chamber. Ensure the material covers the long blade and does not exceed 2/3 of the tank capacity.
3. Secure Lid: Close the lid firmly. Make sure the safety buckles on both sides are fully engaged. If the lid is not properly closed, the grinder will not start.
4. Set Timer: Use the timer switch to set the desired grinding duration (0-5 minutes). For most materials, a short burst of 10-30 seconds is sufficient.
5. Start Grinding: Press the power switch to begin grinding.
6. Monitor: Observe the grinding process. For optimal results and to prevent overheating, do not grind continuously for more than 3 minutes.
7. Rest Period: After each grinding cycle (especially if it lasts close to 3 minutes), allow the machine to rest for 5 to 10 minutes before the next operation.
8. Check Fineness: Once the grinding cycle is complete, open the lid and check the fineness of the powder. If a finer powder is desired, you can use the included sieve to separate coarser particles and re-grind them.
9. Empty Grinder: Carefully tilt the non-detachable jar and use the cleaning brush to brush out the ground powder.

4. Replace: Carefully remove the old blades and install the new spare blades, ensuring they are securely fastened by tightening the lock nut clockwise.

Carbon Brush Replacement:

If the overload protector triggers frequently, it may be time to replace the carbon brushes.

1. Unplug: Disconnect the grinder from the power supply.
2. Locate Brushes: The carbon brushes are typically located on the sides of the motor housing.
3. Replace: Unscrew the caps covering the carbon brushes, remove the old brushes, and insert the new ones. Secure the caps.
