Setup: Setting Your Combination
The ABUS 155/30 lock comes with a factory preset combination, typically 0-0-0. You can easily change this to a personal combination of your choice.
- Open the Lock: Set the dials to the current combination (factory preset is 0-0-0) and pull up the shackle to open the lock.
- Rotate the Shackle: With the shackle open, rotate it 90 degrees (or 180 degrees, depending on the model, usually there's a notch or indicator) until it aligns with a small notch or opening on the lock body.
- Press Down the Shackle: While holding the shackle pressed down firmly into the lock body in this rotated position, set your desired 3-digit combination by rotating the dials. Ensure the numbers are clearly aligned with the indicator line.
- Release and Return Shackle: Release the shackle and return it to its original closed position. Your new combination is now set.
- Test the New 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 reset function if the combination is forgotten without knowing the current code.
Operating the Lock
Opening the Lock
- Align the three numerical dials to your personal combination.
- Pull the shackle upwards to release it from the lock body.
Closing and Securing the Lock
- With the shackle open, insert it back into the lock body.
- Press the shackle down firmly until it clicks into place.
- Scramble the numerical dials to secure the lock and prevent unauthorized opening.
Maintenance
Proper maintenance ensures the longevity and smooth operation of your ABUS combination lock.
- Cleaning: Wipe the lock body and shackle with a soft, dry cloth periodically to remove dust and grime. Avoid harsh chemicals or abrasive cleaners.
- Lubrication: For optimal performance, especially if used in dusty or humid environments, apply a small amount of graphite powder or a silicone-based lubricant to the shackle mechanism and dials once or twice a year. Do not use oil-based lubricants as they can attract dirt.
- Storage: When not in use, store the lock in a dry environment to prevent corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock does not open with the correct combination. | Dials not perfectly aligned; internal mechanism stuck; incorrect combination remembered. | Ensure each number is precisely centered on the indicator line. Gently jiggle the shackle while pulling. Reconfirm your combination. If recently changed, try the old combination. |
| Shackle is stiff or difficult to close/open. | Dirt or debris in the mechanism; lack of lubrication; minor corrosion. | Clean the shackle and opening thoroughly. Apply a small amount of graphite powder or silicone lubricant to the shackle entry points and dials. |
| Cannot change the combination. | Shackle not rotated correctly; shackle not pressed down firmly enough. | Refer to the "Setup: Setting Your Combination" section. Ensure the shackle is rotated 90/180 degrees and pressed down completely before setting new numbers. |
| Forgotten combination. | Combination lost. | Unfortunately, for this type of combination lock, there is no factory reset or master key function if the combination is forgotten. The lock cannot be opened without the correct code. |
