7. Maintenance
- **Cleaning**: Clean the aluminum shell with a soft cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the finish.
- **Inspection**: Regularly inspect all mounting hardware, hinges, and locks for wear or damage. Tighten any loose screws.
- **Lubrication**: Periodically lubricate hinges and lock mechanisms with a suitable lubricant to ensure smooth operation.
- **Waterproofing**: While the box is waterproof, regularly check the seals around the lid for any signs of degradation to maintain its water-resistant properties.
- **Interior Lining**: The PU insulating cotton lining can be removed for cleaning. Hand wash with mild soap and air dry.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Top box feels loose on the rack | Mounting hardware is loose or not properly secured. | Check and tighten all screws and bolts on the base plate and quick-release mechanism. Ensure the box is fully locked onto the base plate. |
| Lid does not close or open smoothly | Hinges or lock mechanism are stiff or obstructed. | Clean any debris from hinges and lock. Apply a small amount of lubricant to moving parts. Ensure the self-lock hinge is properly disengaged when closing. |
| Water ingress into the box | Lid seal is damaged or not properly seated. | Inspect the rubber seal around the lid for cracks or misalignment. Ensure the lid is fully closed and latched. Replace seal if damaged. |
| Keys are stuck or difficult to turn | Lock mechanism is dirty or corroded. | Apply a small amount of graphite lubricant or a specialized lock lubricant into the keyhole. Avoid using oil-based lubricants as they can attract dirt. |
