4. Setup: Setting Your Combination
Your Burg-Wächter 2620 1230 C 120 lock comes with a preset combination, typically 0000. Follow these steps to set your personal four-digit combination:
- Open the Lock: Align the preset combination (e.g., 0000) with the indicator marks on the lock body and pull the shackle open.
- Locate the Reset Mechanism: On the side of the lock mechanism, locate a small reset button or screw. This is often a small knob or a slot that can be turned with a screwdriver or a pen tip.
- Enter Reset Mode:
For a button: Press and hold the reset button.
For a screw/knob: Turn the screw/knob 90 degrees clockwise (or as indicated by an arrow) until it clicks into position. - Set New Combination: While in reset mode, rotate the number dials to your desired four-digit combination. Choose a memorable but secure combination.
- Exit Reset Mode:
For a button: Release the reset button.
For a screw/knob: Turn the screw/knob back 90 degrees counter-clockwise to its original position. - Test the New Combination: Scramble the dials, then enter your new combination and attempt to open the lock. Ensure it opens correctly before scrambling the dials again to lock it.
Important: Make a note of your new combination and store it in a secure location. There is no master key or override for combination locks if the code is forgotten.
5. Operating the Lock
5.1. Locking Your Bicycle
- Wrap the spiral cable around your bicycle frame and a secure, immovable object (e.g., a bike rack, lamppost).
- Insert the free end of the cable into the locking mechanism.
- Scramble the combination dials to secure the lock.
- Gently pull on the cable to ensure it is fully locked and cannot be removed.
5.2. Unlocking Your Bicycle
- Align your personal four-digit combination with the indicator marks on the lock body.
- Pull the shackle or the cable end out of the locking mechanism.
- The lock is now open.
6. Maintenance
- Cleaning: Wipe the lock periodically with a damp cloth to remove dirt and grime. Avoid harsh chemicals.
- Lubrication: If the combination dials become stiff, apply a small amount of silicone-based lubricant to the moving parts. Do not use oil-based lubricants as they can attract dirt.
- Storage: Store the lock in a dry place when not in use to prevent corrosion.
7. Troubleshooting
| Problem | Possible Cause | Solution |
