5. Setup

5.1 Charging the Grinder

Before first use, fully charge the grinder. The device is equipped with two built-in 800mAh lithium batteries.

1. Locate the USB Type-C charging port, usually protected by a silicone cover.
2. Plug the provided USB Type-C cable into the port and connect the other end to a suitable power source (e.g., USB wall adapter, computer).
3. The LED indicators will show charging status. A full charge can provide 30-50 grinds for pour-over or 15 grinds for espresso.

5.2 Adjusting Grind Settings

The grind adjustment dial is located at the bottom of the OX grinder. It offers 20 precision settings.

1. Tightening the Dial: Gently twist the dial towards the "FINE" direction. Use moderate force; avoid excessive pressure to prevent damage.
2. 0 Setting: When the dial is turned to the tightest position (towards FINE), this is the 0 setting, suitable for the finest espresso grind.
3. Adjusting to Coarse: After the dial is fully tightened, adjust to your desired grind setting by turning it towards the "COARSE" side. Each 'click' represents one setting. For example, 1 click = setting 1, 2 clicks = setting 2, and so on.

6. Operation

6.1 Adding Coffee Beans

1. Remove the top lid of the grinder.
2. Pour whole coffee beans into the bean hopper. The maximum capacity is 60g, but 30g is recommended for light roasts or espresso for optimal performance.
3. Replace the top lid securely.

6.2 Grinding Process

1. Ensure the grinds cup is attached to the bottom of the grinder.
2. Press the 'O' button to start grinding. The grinder will operate for a 15-second cycle and then automatically shut off.
3. To stop grinding manually before the cycle ends, press the 'X' button.
4. After grinding, remove the grinds cup to access your fresh coffee grounds.

7. Usage Tips

• Continuous Grinding: For best results, limit continuous grinding to approximately 10 sessions for pour-over coffee or 3 sessions for espresso. This prevents activating the overheat protection system. If triggered, allow a 15-minute cooldown.
• Unground Beans: Occasionally, some beans may remain unground during operation. A gentle shake of the grinder will help resolve this and ensure even grinding.
• Static Grounds: After grinding, tap the bottom of the grinder with moderate force to help release coffee grounds stuck at the exit due to static.

8. Cleaning & Maintenance

• Always clean the grinder with the included brush after each use.
• For best results, grind 1-2g of coffee beans before use to clean the interior.
• Important: Never wash the grinder with water to avoid damaging the circuit board and internal components.
• The grinder features a detachable design for easier cleaning of the burrs and internal parts.

9. Troubleshooting

• Grinder not starting: Ensure the battery is charged. Check if the lid and grinds cup are securely attached.
• Inconsistent grind: Verify that the grind adjustment dial is set correctly for your desired brew method. Ensure burrs are clean and free of debris.
• Grinder stops unexpectedly: This may indicate the overheat protection has been activated. Allow the device to cool down for 15 minutes before resuming use.
• Beans not grinding: Check if the bean hopper is empty or if beans are jammed. Gently shake the grinder to dislodge any stuck beans.
