4. Operating Instructions

Setting Your Combination

The initial password for the lock is 0-0-0-0. Follow these steps to set your personalized 4-digit combination:

1. Open the Lock: Ensure the lock is set to the current combination (initially 0-0-0-0) and the bolt is in the open position.
2. Access Reset Mechanism: Locate the small plug on the side of the lock body. Remove this plug.
3. Lift the Bolt Switch: Pull the bolt switch (the knob that slides the bolt) up to position 'B' (fully extended and lifted).
4. Set New Combination: While the bolt switch is in position 'B', rotate the number dials to your desired 4-digit combination. Ensure the numbers are clearly aligned with the indicator line.
5. Lock in New Combination: Push the bolt switch back down to position 'A' (flush with the lock body).
6. Replace Plug: Reinsert the small plug into its slot.
7. Test New Combination: Scramble the dials and then enter your new combination to ensure it opens correctly.

5. Maintenance

• The lock features a rust-resistant coating. To maintain its performance and appearance, clean the lock periodically with a soft, damp cloth.
• Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
• For optimal operation, especially in outdoor or dusty environments, apply a small amount of silicone-based lubricant to the sliding bolt and combination dials annually.
• Ensure the combination dials turn smoothly. If they become stiff, lubrication may be required.

6. Troubleshooting

Unable to Open or Lock by Default Password (0-0-0-0)

If the lock does not open or lock with the default password, please confirm that all four numbers (0-0-0-0) are completely and precisely aimed at the indicator line. Slight misalignment can prevent the lock from engaging or disengaging. If they are perfectly aligned and it still doesn't work, try combinations with numbers close to 0, such as 0-1-0-1, 1-1-0-0, 9-0-9-0, or 9-1-1-0, as the factory setting might have a slight variance.

Unable to Open After Setting a New Password

If you have set a new password and cannot open the lock, it is likely due to an error during the password setting process. The lock will not open if the new combination was not correctly registered. Review the steps in the "Setting Your Combination" section carefully. If you are certain of your new code, but it still doesn't work, try combinations that are very close to your intended code (e.g., if your code was 8-8-8-8, try 7-8-8-8, 8-9-8-8, 8-8-9-9, etc.) as a dial might have shifted slightly during the setting process. If the issue persists, you may need to contact customer support.
