2. Setup: Setting Your Combination
Your Kryptonite combination padlock is factory preset to open at 0-0-0. Follow these steps to set your personal combination:
- Ensure the padlock is open. If it is currently locked, rotate the dials to 0-0-0 and pull up the shackle.
- With the shackle in the open position, rotate it 90 degrees (a quarter turn) counter-clockwise.
- Press the shackle down firmly into the lock body. Hold it in this depressed position.
- While holding the shackle down, rotate the dials to set your desired three-digit combination. Ensure the numbers are aligned precisely with the indicator line.
- Release the shackle.
- Rotate the shackle back to its original open position (90 degrees clockwise).
- Push the shackle down to lock the padlock. Scramble the dials to secure your new combination.
Important: Remember your combination. There is no master key or override to open the lock if the combination is forgotten.
3. Operating the Padlock
Opening the Padlock:
- Rotate the dials to align your personal three-digit combination with the indicator line on the padlock body.
- Pull the shackle upwards to release it from the lock body.
Closing the Padlock:
- Align the shackle with the opening in the lock body.
- Push the shackle down firmly until it clicks into place.
- Scramble the dials to a random set of numbers to secure the padlock.
4. Maintenance
To ensure the longevity and smooth operation of your Kryptonite combination padlock, follow these maintenance guidelines:
- Cleaning: Wipe the padlock body and shackle with a soft, damp cloth to remove dirt and grime. Avoid harsh chemicals or abrasive cleaners.
- Lubrication: Periodically apply a small amount of graphite-based lubricant or a silicone spray to the shackle mechanism and the dial assembly. This helps prevent corrosion and ensures smooth movement of the dials and shackle. Do not use oil-based lubricants as they can attract dirt.
- Storage: Store the padlock in a dry environment when not in use to prevent rust and corrosion.
5. Troubleshooting Common Issues
- Issue: Padlock is difficult to open or dials are stiff.
Solution:
- Ensure your combination is precisely aligned with the indicator line. Even a slight misalignment can prevent opening.
- Apply a graphite-based lubricant or silicone spray to the dial mechanism and shackle. Work the dials and shackle to distribute the lubricant.
- Check for any debris or foreign objects obstructing the dials or shackle.
- Issue: Padlock will not lock.
Solution:
- Ensure the shackle is fully inserted into the lock body.
- Scramble the dials after closing the shackle to engage the locking mechanism.
- Issue: Combination is forgotten.
Solution: Unfortunately, if the combination is forgotten, there is no way to reset it without knowing the original combination. The padlock will need to be cut or replaced.
