Using a 4-Digit Combination Padlock for the First Time

A 4-digit combination padlock usually comes with a factory default code. In most cases, the default combination is: 0000

To open the lock:

• Align all four dials to 0000.
• Pull up the shackle or press the release button, depending on the lock design.

It is highly recommended that you change the default code immediately for better security.

How to Set Your Combination Code

Follow these general steps:

1. Open the lock using the default code (0000).
2. Pull the shackle up and turn it 90 degrees counterclockwise to the Code Setting Gap.
3. Press and hold the shackle down. Then turn it counterclockwise again and let go.
4. The shackle stays down, and now you can rotate the numbers to set your new code.
5. Turn the shackle clockwise to return it to its original position to complete the process.
6. Your new code is set. Test it by locking and unlocking the lock.
7. To lock, push the shackle down and turn the numbers to random codes. To unlock, turn the numbers to set your code, making sure the numbers align properly.

Choose a code that is easy for you to remember but difficult for others to guess.

Changing the Existing Combination Code

If you already have a code set and want to change it:

1. Open the lock using the current combination.
2. Pull the shackle up and turn it 90 degrees counterclockwise to the Code Setting Gap.
3. Press and hold the shackle down. Then turn it counterclockwise again and let go.
4. The shackle stays down, and now you can rotate the numbers to set your new code.
5. Turn the shackle clockwise to return it to its original position to complete the process.
6. Your new code is set.

Always make sure the new code is properly saved before closing the lock completely.

Safety Tips

• To avoid getting locked out of your padlock, follow these important safety tips:
• Always take a photo of your combination code or write it down in a safe place.
• Avoid using obvious combinations such as 1234, 0000, or your birth year.
• Do not share your code with too many people.
• Test the code multiple times after changing it.
• Keep the lock clean and dry to prevent rust or stiffness.
• Forgetting your combination code may render the lock inoperable, especially if there is no reset option available.

Conclusion

Using a 4-digit combination lock is simple once you understand how the locking and reset system works. Always test your new combination after setting it to avoid accidental lockouts.
