3. Operating Instructions
To Unlock the Padlock:

- With the key turned, the shackle will spring open.
- Remove the key.
To Lock the Padlock:
- Close the shackle by pushing it firmly into the padlock body until it clicks into place.
- Insert the key into the keyway.
- Turn the key counter-clockwise approximately 90 degrees until it stops.

4. Maintenance
Proper maintenance ensures the longevity and reliable operation of your Abloy Protec2 PL 321 Padlock.
- Cleaning: Periodically wipe the padlock body and shackle with a soft, dry cloth to remove dirt and grime. Avoid abrasive cleaners or solvents.
- Lubrication: For optimal performance, especially in dusty or harsh environments, apply a small amount of a non-greasy, non-silicone-based lubricant specifically designed for disc detainer locks into the keyway once or twice a year. Do not use oil-based lubricants as they can attract dirt and clog the mechanism.
- Key Care: Keep your keys clean and free from debris. Avoid using keys for purposes other than operating the lock, as this can bend or damage them.
