4. Guide d'installation
The KOTARBAU door handle is designed for screw-on installation and is universally applicable for various door types and lock mechanisms (BB, PZ, WC/BAD). Follow these steps for proper installation:
- Préparez la porte : Ensure your door is pre-drilled with the necessary holes for the spindle and mounting screws. The handle is compatible with standard 72mm center-to-center distance for lock mechanisms.
- Insérer la broche : Slide the 8mm square spindle through the latch mechanism in the door.
- Position the Handle Plates: Place one handle plate on each side of the door, aligning the spindle hole and screw holes with those on the door. Ensure the lever handles are pointing in the desired direction (e.g., downwards).
- Fixez les poignées : Slide the lever handles onto the spindle from both sides. Secure each handle to its plate using the small grub screw located on the underside of the lever, tightening it with the provided Allen key.
- Secure the Plates: Using the provided mounting screws, firmly attach both handle plates to the door. Ensure the plates are flush against the door surface and do not wobble.
- Opération de test : After installation, test the door handle by pressing the lever down and ensuring the latch retracts smoothly. Also, check the locking mechanism (if applicable) for proper function.


5. Fonctionnement
Operating the KOTARBAU door handle is straightforward:
- To open the door, simply press the lever handle downwards. This action retracts the latch bolt, allowing the door to open.
- Release the lever handle, and it will return to its horizontal position, extending the latch bolt to secure the door.
- For doors with a locking mechanism (e.g., key or thumb-turn), use the appropriate method to lock or unlock the door before operating the handle.

6. Maintenance et entretien
To ensure the longevity and appearance of your KOTARBAU door handle, follow these maintenance guidelines:
- Nettoyage: Essuyez régulièrement la poignée avec un chiffon doux et sec.amp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the satin nickel finish.
- Lubrification: Periodically apply a small amount of silicone-based lubricant to the moving parts of the latch mechanism and the spindle to ensure smooth operation.
- Contraction: Check all mounting screws and the grub screw on the lever periodically. Tighten them if they have become loose to prevent wobbling and ensure security.
- Inspection: Inspect the handle for any signs of wear or damage. If any significant damage is observed, consider replacing the unit.
