Regular care and maintenance are crucial for ensuring the long-term functionality, smooth operation, and security of your Winkhaus window transmission system. Follow these guidelines to prolong the life of your hardware.

Periodically clean the visible parts of the transmission mechanism and the window frame with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the galvanized finish or other components.
Lubrication (Annually):
At least once a year, apply a suitable lubricant (e.g., silicone-free spray, technical grease, or specialized window hardware lubricant) to all moving parts, locking points, hinges, and connection rods. This reduces friction, prevents wear, and ensures smooth operation. Refer to the included ToniTec manual for specific lubrication points.
Inspection (Annually):
Regularly inspect the entire transmission system for any signs of wear, damage, corrosion, or loose screws. Pay particular attention to the connection points and locking elements. Tighten any loose screws immediately. Replace any damaged components promptly to maintain security and functionality.
