Operating Instructions
Setting and Resetting the Password
The initial password for your lock is 0000. To set a new personal combination:
- Open the lock using the current password (initially 0000).
- Locate the small round button (often labeled 'B' or similar) on the side of the lock mechanism. Press and hold this button without releasing it.
- While holding the button, turn the number dials to your desired 4-digit combination.
- Release the button. Your new password is now set.
- To lock, insert the lock piece and scramble the numbers. To unlock, align the dials to your set password and press the unlock button (often labeled 'A').

Maintenance
To ensure the longevity and smooth operation of your West Biking lock, follow these maintenance guidelines:
- Cleaning: Wipe the lock periodically with a damp cloth to remove dirt and grime. Avoid harsh chemicals that may damage the ABS coating.
- Lubrication: If the combination dials or locking mechanism become stiff, apply a small amount of silicone-based lubricant.
- Storage: When not in use, store the lock in a dry environment to prevent potential rust or corrosion, although the ABS coating offers significant protection.

Troubleshooting
Forgotten Combination
If you forget your 4-digit combination, there is no master key or reset button that will reveal the code. It is highly recommended to:
- Choose a memorable combination, such as a birthday or an important date.
- Take a photo of your set combination with your mobile phone and store it securely.
- Record the combination in a secure digital note or physical document.
Without the correct combination, the lock cannot be opened non-destructively.
