3. Operating the Lock

3.1 Locking Your Bicycle

1. Position your bicycle: Place your bicycle next to a fixed, immovable object such as a bike rack, lamppost, or sturdy fence.
2. Use the D-Lock: Pass the U-shaped shackle of the D-lock through the frame of your bicycle and around the fixed object. Ensure that the shackle also passes through at least one wheel if possible. Insert the shackle ends into the lock body and turn the key to secure. Remove the key.
3. Use the Looped Cable (Optional, for added security): For additional security, especially for securing both wheels or accessories, thread the looped cable through the remaining wheel(s) and any quick-release components. Loop one end of the cable through the other, then secure the free end of the cable to the D-lock shackle before locking.

3.2 Unlocking Your Bicycle

1. Insert the key fully into the key cylinder.
2. Turn the key to unlock the shackle.
3. Remove the shackle from the lock body and detach the cable if used.
4. Store the lock and cable securely, preferably using the mounting bracket on your bike.

4. Maintenance

To ensure the longevity and optimal performance of your Master Lock 8285EURDPRO D-Lock and Cable, follow these maintenance guidelines:

• Lubrication: Periodically apply a small amount of graphite-based lubricant or a specialized lock lubricant into the key cylinder. This helps maintain smooth operation and prevents corrosion. Avoid using oil-based lubricants as they can attract dirt.
• Cleaning: Wipe down the lock body and shackle with a damp cloth to remove dirt and grime. Ensure the lock is dry before storage.
• Rust Resistance: The lock is designed to be rust-resistant. However, prolonged exposure to harsh weather conditions can still affect its finish. Store the lock in a dry place when not in use.
• Key Care: Keep your keys clean and free from debris. Avoid forcing the key if it feels stiff.
