Maintenance
The Puroma combination lock is designed for durability and minimal maintenance. To ensure its longevity and smooth operation:
- Cleaning: Wipe the lock periodically with a soft, damp cloth to remove dirt and grime. Avoid harsh chemicals that may damage the finish.
- Lubrication: For optimal performance, especially in outdoor or dusty environments, apply a small amount of graphite lubricant or silicone spray to the shackle mechanism and number wheels once a year.
- Storage: When not in use for extended periods, store the lock in a clean, dry place.

Troubleshooting
- Lock will not open with the correct combination:
- Ensure all four digits are perfectly aligned with the indicator line.
- Verify that you are using the correct combination. If you have recently reset it, try the new combination.
- If the lock feels stiff, apply a small amount of lubricant to the dials and shackle.
- Cannot reset the combination:
- Make sure the current combination is correctly set and the shackle is pulled up before attempting to rotate it.
- Ensure the shackle is pushed down completely into the code setting gap before rotating it to the new position.
- Refer to the "Setup: Setting Your Combination" section for detailed steps.
- Forgotten Combination:
Unfortunately, if the combination is forgotten and not written down, there is no master key or backdoor to open the lock. The lock is designed for security, and without the correct combination, it cannot be opened non-destructively.
