6. Maintenance
To ensure smooth operation and extend the life of your Trelock U-lock:
- Lubrication: Periodically apply a small amount of lock lubricant (e.g., graphite-based or silicone-free spray) into the keyhole and the shackle insertion points. Operate the lock several times after lubrication to distribute it evenly.
- Cleaning: Wipe the lock body and shackle with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the protective coating.
- Storage: When not in use, store the lock in a dry environment to prevent rust and corrosion.
7. Troubleshooting
| Problem | Possible Cause | Solution |
