5. Operating Instructions

To effectively secure your bicycle, follow these guidelines:

1. Locking Your Bike:
   • Choose a secure, immovable object (e.g., a bike rack, lamppost) to lock your bike to.
   • Position the U-Lock to secure the bicycle frame and at least one wheel to the immovable object. Aim for a tight fit to minimize space for leverage attacks.
   • Insert the key into the disc-style cylinder and turn to lock the shackle. Remove the key.
   • Use the 4ft KryptoFlex cable to secure the front wheel or other accessories (like a helmet) by looping it through the U-lock and the desired component.
2. Unlocking Your Bike:
   • Insert the key into the cylinder. The rotating dustcover should be moved aside first.
   • Turn the key to unlock the shackle.
   • Remove the U-lock and KryptoFlex cable from your bike and the immovable object.
3. Key Safe Program: Register your key number with Kryptonite. In case of lost keys, Kryptonite can send you free replacement keys. Visit the Kryptonite website for registration details.

6. Maintenance

Regular maintenance will extend the life and functionality of your lock:

• Lubrication: Periodically apply a small amount of graphite powder or a silicone-based lubricant to the lock cylinder to ensure smooth operation, especially in dusty or wet conditions.
• Cleaning: Wipe down the U-lock and cable with a damp cloth to remove dirt and grime. The protective vinyl coating helps prevent scratches and corrosion.
• Dustcover: Always ensure the rotating dustcover is closed when the lock is not in use to protect the cylinder from moisture and debris.

7. Troubleshooting

If you encounter issues with your lock, consider the following:

• Stiff or Sticky Cylinder: Apply lubricant as described in the Maintenance section. Ensure the key is fully inserted and turned correctly.
• Shackle Not Engaging: Check for any obstructions in the locking mechanism or if the shackle is misaligned. Ensure the key is fully turned to the locked position.
• Lost Keys: Utilize the Key Safe Program by contacting Kryptonite with your registered key number for replacement keys.
