5. Maintenance
5.1 Cleaning
- Always ensure the screwdriver is turned off and disconnected from any charging source before cleaning.
- Wipe the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the ventilation openings clear of dust and debris.
5.2 Storage
- Store the screwdriver and its accessories in a dry, cool place, away from direct sunlight and moisture.
- Keep out of reach of children.
- For long-term storage, it is recommended to charge the battery periodically (e.g., every 3-6 months) to maintain battery health.
6. Troubleshooting
- Screwdriver not turning on: Ensure the battery is charged. Connect to a USB power source and allow sufficient charging time. Check that the forward/reverse switch is not in the middle (manual) position.
- Bits slipping or stripping screws: Ensure you are using the correct bit type and size for the screw. Apply adequate, but not excessive, pressure.
- Reduced power or short battery life: The battery may need a full charge. Over time, all rechargeable batteries experience reduced capacity. If the issue persists after a full charge, the battery may be nearing the end of its lifespan.
- LED light not working: Check if the trigger switch is fully pressed. If the issue persists, contact customer support.

8. User Tips
