Setup: Setting Your Combination
Your ABUS Combiflex lock comes with a factory default combination, typically "0000". Follow these steps to set your personal 4-digit combination:
- Ensure the lock is set to the factory default code (0000) or your current known combination. The numbers should be aligned in the center viewing window.
- With the cable fully retracted, firmly push the steel nub of the cable (the end that inserts into the lock body) downwards into the device. Hold it in this depressed position.
- While holding the cable nub down, rotate the combination dials to your desired 4-digit code. Make sure the numbers are clearly aligned.
- Release the steel nub. Your new combination is now set.
- To test your new combination, press the larger button on the left side of the lock to release the cable. Pull the cable out. Then, insert the cable end back into the opening. With your new combination set, you should be able to press the smaller button on the right to release the cable. If it doesn't release, re-check your combination and repeat the steps.
Important: Always ensure the cable end is not accidentally pressed in when storing the lock, as this could inadvertently change the combination if the dials are moved.

Maintenance
To ensure the longevity and smooth operation of your ABUS Combiflex lock, follow these simple maintenance guidelines:
- Cleaning: Periodically wipe down the lock body and cable with a soft, damp cloth to remove dirt and grime. Avoid harsh chemicals or abrasive cleaners.
- Lubrication: If the cable retraction or dial movement becomes stiff, apply a small amount of silicone-based lubricant to the cable entry point and the combination dials. Work the cable in and out and rotate the dials to distribute the lubricant. Avoid oil-based lubricants as they can attract dirt.
- Storage: Store the lock in a clean, dry place when not in use to prevent corrosion and accumulation of debris.
Troubleshooting
If you encounter issues with your ABUS Combiflex lock, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Cannot set or reset combination. | Ensure the lock is set to the current correct combination (factory default 0000 or your last set code) before attempting to reset. Make sure the cable's steel nub is fully depressed and held down firmly while setting the new code. Verify that the new numbers are perfectly aligned in the viewing window before releasing the nub. |
| Cable does not retract smoothly or gets stuck. | Dirt or debris may be obstructing the mechanism. Clean the cable and the entry point. Apply a silicone-based lubricant to the cable and mechanism as described in the Maintenance section. |
| Lock does not open with the correct combination. | Ensure the dials are precisely aligned with your combination. Even a slight misalignment can prevent opening. Confirm you are using the correct combination. If you recently changed it, try both the old and new codes (if you are unsure). The combination might have been accidentally changed if the cable nub was pressed in while the dials were moved. Refer to the "Setting Your Combination" section for recovery steps if you suspect this. |
