Setup and Installation
Follow these steps for a successful installation:
- Preparation: Ensure your door is prepared with the correct boreholes for the spindle and mounting screws. The distance between the center of the spindle hole and the center of the keyhole should be 72mm.
- Insert Spindle: Insert the square spindle through the latch mechanism in the door.
- Position Handles: Place one handle plate on each side of the door, aligning the spindle with the handle's receiver and the screw holes with the pre-drilled holes in the door.
- Secure with Screws: Insert the mounting screws through the holes on one side of the handle plate and thread them into the sleeve nuts on the other side. Tighten securely but do not overtighten.
- Test Operation: After installation, test the door handle by pressing the lever down to ensure the latch retracts smoothly and returns to its original position when released.

Operating Instructions
The KOTARBAU Door Handle is designed for simple and intuitive operation:
- To open the door, simply press the handle lever downwards. This will retract the latch, allowing the door to open.
- Release the handle lever to allow the latch to extend back into the strike plate, securing the door when closed.
- For models with a keyhole (BB - for the lock), insert the appropriate key and turn to engage or disengage the lock mechanism.

Maintenance
To ensure the longevity and smooth operation of your KOTARBAU Door Handle, follow these maintenance tips:
- Cleaning: Wipe the handle regularly with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the aluminum finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the moving parts of the latch mechanism (not the handle itself) to ensure smooth operation.
- Tightening: Check the mounting screws periodically and tighten them if they have become loose. Do not overtighten.
