4. Operating Instructions

4.1 Preparing for Grinding

  1. Ensure the grinding chamber is clean and dry.
  2. Add the desired amount of dry material into the grinding chamber. Do not overfill; the capacity is 300g (0.66lb).
  3. Close the lid tightly. Ensure both safety buckles are engaged and you hear a clear click, indicating the induction switch is triggered. The machine will not operate if the lid is not properly secured.

4.2 Grinding Process

  1. Once the lid is securely closed, connect the power.
  2. Rotate the timer switch to set the desired grinding time (0-5 minutes). The grinder will start automatically.
  3. For general grains, 30 seconds to 3 minutes is typically sufficient to achieve a fine powder. Adjust grinding time based on the material and desired fineness.
  4. To stop the operation immediately, turn the timer switch back to zero.

4.3 Grinding Results and Material Suitability

The grinder is effective for a wide range of dry materials, including grains, spices, coffee beans, and herbs. The fineness of the grind can be adjusted by varying the grinding time.

  • If the initial grinding result is not fine enough, you can sieve out coarse particles and grind them again.
  • Suitable Materials: Grains (wheat, corn, rice, soybeans), spices (pepper, cumin, dried chili), herbs, coffee beans, animal feed.
  • Unsuitable Materials: Wet, fresh, oily, or sticky materials (e.g., fresh fruits, meat, nuts with high oil content, sugar). These materials can damage the grinder or lead to poor performance.

  1. Ensure the grinder is unplugged.
  2. Locate the carbon brush covers on the sides of the motor housing.
  3. Use a flattened tip screwdriver to loosen the nut on the carbon brush cover.
  4. Carefully remove the old carbon brush.
  5. Install a new carbon brush from the provided set and tighten the nut securely.
  6. Replace both carbon brushes together for balanced performance.

6. Troubleshooting

Grinder Does Not Start

  • Lid Safety Device: If the machine does not start after being turned on, it may be because the induction switches inside the safety device are not triggered. Adjust the lid to ensure both rods are pushed completely into the buckle structures on both sides, leaving no space. Ensure you hear a clear click when closing the lid.
  • Power Connection: Check if the power cord is securely plugged into a working electrical outlet.
  • Timer Setting: Ensure the timer switch is set to a grinding duration and not at zero.
