User Tips
- Check Package Contents: Upon receiving your screwdriver set, carefully check all items against the 'Package Contents' section to ensure you have received the screwdriver, charging cable, extension rod, and all specified bits, including the storage case if applicable to your purchased kit.
- Optimal Torque: Always start with a lower torque setting and gradually increase it if more power is needed. This prevents overtightening and stripping screws, especially with delicate materials.
- Manual Finish: For very tight screws or when precise control is required, use the manual operation feature to finish tightening or loosening after initial electric use.
