Operating Instructions
Operating your ABUS 20/70 Diskus Padlock is straightforward:
- Unlocking: Insert the key fully into the keyway. Turn the key clockwise until the shackle releases. Pull the shackle open.
- Locking: Position the padlock so the shackle aligns with the locking mechanism. Push the shackle closed. Insert the key fully into the keyway and turn it counter-clockwise until it stops. The key can then be removed, indicating the padlock is securely locked.
Important Note: The key is designed to be removable only when the padlock is in the locked position. This is a security feature to prevent accidental unlocking.

Maintenance
Regular maintenance ensures the smooth operation and extends the lifespan of your padlock.
- Cleaning: Periodically wipe the padlock body with a clean, dry cloth to remove dirt and debris. The cylinder cover helps protect the internal mechanism from environmental elements.
- Lubrication: For outdoor use or if the mechanism feels stiff, apply a small amount of lock lubricant (e.g., graphite-based or silicone-free spray) into the keyway. Avoid using oil-based lubricants as they can attract dirt.
- Cylinder Cover: Ensure the cylinder cover is properly closed when the padlock is not in use to prevent water and dirt ingress.

Troubleshooting
If you encounter issues with your ABUS 20/70 Diskus Padlock, consider the following:

- Apply lock lubricant as described in the Maintenance section.
- Check for any foreign objects in the keyway.
- Padlock Does Not Lock:
- Ensure the shackle is fully closed and seated correctly.
