Setup: Setting Your Combination Code
Your CINCINNO 4-Digit Combination Disc Padlock comes with a factory preset combination of 0-0-0-0. Follow these steps to set your personal combination:
- Open the Lock: Ensure the lock is set to the default combination (0-0-0-0) and open the shackle.
- Locate the Reset Screw: On the side or back of the lock, you will find a small screw or button. Use a small clip or screwdriver to turn this screw from position 'A' to position 'B' (usually a 90-degree counter-clockwise turn).
- Set New Combination: With the screw in position 'B', rotate the combination dials to your desired 4-digit code. Ensure the numbers are clearly aligned with the indicator marks.
- Secure New Combination: Turn the screw back from position 'B' to position 'A' (clockwise). Your new combination is now set.
- Test the Combination: Scramble the dials and then enter your new combination to ensure the lock opens correctly.
Important: Remember your new combination. There is no master key or override function if the combination is forgotten.

Maintenance
To ensure the longevity and smooth operation of your CINCINNO combination padlock, consider the following maintenance tips:
- Regular Cleaning: Wipe the lock body and dials with a soft, damp cloth to remove dirt and grime. Avoid abrasive cleaners.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the shackle mechanism and combination dials, especially if used in harsh outdoor conditions. This helps prevent sticking and corrosion.
- Inspect for Damage: Regularly check the lock for any signs of wear, damage, or corrosion. Address any issues promptly to maintain security.
- Environmental Protection: While designed to be weatherproof, extreme conditions can still affect performance. If possible, shield the lock from prolonged direct exposure to heavy rain, snow, or extreme temperatures.
