- Once fully charged, the indicator will show a steady light.
5.2. Battery Level Display
The Battery Level Display (5) indicates the approximate charge level:
- 100%
- 60%
- 20%
- 5%
- 0%
5.3. Important Charging Notes
- Do not use the electric screwdriver while it is charging.
- Before first use, ensure the battery is fully charged. The initial charging time should not exceed 2.5 hours.
- To maintain optimal performance and battery life, recharge the electric screwdriver at least once a month, even if not in use.
- Only use the provided charging cable for charging.
6. Maintenance
- Cleaning: Wipe the screwdriver body and bits with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the screwdriver and its accessories in a dry, cool place, away from direct sunlight and moisture. Keep out of reach of children.
- Battery Care: As mentioned in the charging instructions, recharge the screwdriver at least once a month to maintain battery health, even if not in regular use.
- Bit Magnetism: If the magnetic force of the bits weakens, use the included magnetizer to restore it.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Screwdriver does not turn on. | Battery is depleted. | Charge the screwdriver fully using the provided Type-C cable. |
| Low power or insufficient torque. | Battery is low or incorrect gear selected. | Recharge the battery. Select a higher gear (2nd or 3rd) for more torque. For very tight screws, use manual torque (up to 3N.m). |
| Bits are not holding screws. | Bit magnetism has weakened. | Use the included magnetizer to re-magnetize the bit. |
| LED light does not turn on. | Light function not activated or battery low. | Press and hold the LED Light Switch & Gear Shift Button (4) for 1 second. Ensure the battery is charged. |
| Motor/gearbox makes unusual noise or stops. | Potential motor or gearbox play. | If you experience this, discontinue use and contact customer support. (Some users have reported fixing this by disassembling and adding a washer, but this is not officially recommended.) |
