How to use
To install the Łucznik AP PREMIUM cylinder, first remove the existing cylinder by unscrewing the fixing screw located on the edge of the door leaf. Insert the new cylinder into the lock case, ensuring the cam is aligned correctly to allow for smooth operation. Once inserted, re-insert and tighten the fixing screw securely. Test the operation of the lock with the key from both sides of the door while the door is open to ensure the mechanism functions correctly before closing the door.
What to consider before purchase
Verify the required cylinder dimensions (30/40 mm) for your specific door thickness
Ensure compatibility with your existing mortise lock
Check if the door hardware allows for a satin finish match
Usage recommendations
Regularly maintain the cylinder by using a dedicated graphite-based lubricant to ensure smooth operation. Avoid using oil-based lubricants as they may attract dust and debris, which can impair the internal locking pins over time.
