Operating Instructions
To secure your bicycle using the Adaptor Chain 6KS:
- Ensure the Adaptor Chain 6KS is properly inserted into your compatible ABUS frame lock.
- Wrap the chain around a sturdy, fixed object such as a lamppost, bike rack, or railing.
- Pass the free end of the chain through a part of your bicycle's frame or wheel.
- Connect the free end of the chain back to the frame lock, if applicable, or ensure it is securely looped around the fixed object and the bicycle.

Here, the ABUS Adaptor Chain 6KS is shown in practical use, securing a bicycle to a sturdy pole. The chain wraps around both the bicycle frame and the fixed object, providing additional security beyond the frame lock alone. This demonstrates how the chain extends the locking capabilities of the bicycle.

Maintenance
To ensure the longevity and optimal performance of your ABUS Adaptor Chain 6KS, follow these simple maintenance guidelines:
- Cleaning: Wipe the chain and its plastic coating with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the coating.
- Lubrication: Periodically apply a small amount of bicycle chain lubricant to the metal parts of the insertion bolt to ensure smooth operation.
- Storage: Store the chain in a dry place when not in use to prevent rust, especially if it has been exposed to moisture.
- Inspection: Regularly inspect the chain for any signs of wear, damage, or corrosion. If significant damage is observed, consider replacing the chain for continued security.
Troubleshooting
If you encounter any issues with your ABUS Adaptor Chain 6KS, please consider the following:
- Difficulty Inserting/Removing: Ensure the insertion bolt is clean and free of debris. A small amount of lubricant on the bolt may help. Verify that you are using a compatible ABUS frame lock.
- Chain Not Securing: Double-check that the chain is fully inserted into the frame lock and that the frame lock itself is functioning correctly.
- Damage to Coating: While the plastic coating is durable, sharp objects can damage it. This does not affect the security of the hardened steel chain but may reduce aesthetic appeal.
