Setup and First Use
- Inspect Contents: Verify that all package contents are present and undamaged.
- Register Your Key: It is highly recommended to register your XPlus Code Card with ABUS. This allows for secure key replacement should you lose your original keys. Keep the code card in a safe place, separate from your keys.
- Test the Lock: Before securing your valuable, insert a key into the lock cylinder and turn it to ensure smooth operation. The lock should open and close without excessive force.
- Mounting the Bracket (Optional): If your lock includes the USH 540 bracket, attach it to your bicycle frame according to the bracket's specific instructions. This provides a secure and rattle-free transport solution for your U-lock.
Operating the Lock
Locking Procedure:
- Position the U-lock around the object you wish to secure (e.g., bicycle frame and a fixed object).
- Align the shackle ends with the openings in the lock body.
- Push the shackle firmly into the lock body until it clicks into place. The lock is now engaged.
- Remove the key.
Unlocking Procedure:
- Insert the key fully into the lock cylinder.
- Turn the key clockwise (or counter-clockwise, depending on the lock's orientation) until the shackle releases from the lock body.
- Pull the shackle completely out of the lock body.
- Remove the key.
Important: Always ensure the lock is fully engaged and the key is removed before leaving your secured item unattended.
Maintenance
Regular maintenance ensures the smooth operation and extends the lifespan of your ABUS Granit XPlus 54 Mini U-Lock.
- Lubrication: Periodically (e.g., every 3-6 months, or more frequently in harsh environments), apply a small amount of non-greasy lock lubricant (e.g., ABUS lock spray or graphite-based lubricant) into the keyway and where the shackle enters the lock body. Avoid using oil-based lubricants as they can attract dirt.
- Cleaning: Keep the lock body and shackle clean from dirt and debris. Use a damp cloth to wipe down the exterior.
- Key Care: Do not force the key if it feels stiff. Ensure the key is fully inserted and the lock cylinder is free of obstructions. Avoid using damaged or bent keys.
Troubleshooting
