4. Setup and Installation
Installation of the Winkhaus GRM 1793858 window transmission should be performed by individuals with appropriate technical knowledge. The following steps are general guidelines:
- Preparation: Ensure the window sash is clean and free from debris. Remove any old or damaged transmission components carefully.
- Positioning: Place the new GRM 1793858 transmission into the designated channel on the window sash. Ensure it aligns correctly with all pre-drilled holes and connection points.
- Securing: Fasten the transmission to the window sash using appropriate screws. Do not overtighten, as this can deform the profile or damage the mechanism.
- Connecting: Connect any associated rods or corner drives to the transmission as required by the window system.
- Testing: Before closing the window, operate the transmission handle to ensure smooth movement of all locking points. Adjust if necessary.
- Final Check: Close the window and check for proper sealing and locking. The window should operate smoothly without excessive force.
5. Operating Instructions
The Winkhaus GRM 1793858 transmission facilitates the opening, closing, and tilting functions of your window. Operation is typically controlled via a window handle (not included with the transmission).
- Closing: Turn the window handle to the fully downward position. This engages all locking points, securing the window in the closed position.
- Opening (Side-Hung): From the closed position, turn the handle 90 degrees to the horizontal position. The window can now be pulled open from the side.
- Tilting (Bottom-Hung): From the closed position, turn the handle 180 degrees to the fully upward position. The window will tilt inwards from the top, allowing for ventilation.
- Important: Always ensure the handle is fully engaged in one of the positions (closed, open, or tilt) before attempting to move the window. Forcing the window when the handle is in an intermediate position can cause damage.
6. Maintenance
Regular maintenance ensures the longevity and smooth operation of your Winkhaus GRM 1793858 window transmission. The product includes ToniTec maintenance instructions for autopilot systems, which generally cover the following aspects:

- Cleaning: Periodically clean the visible parts of the transmission and the window rebate with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Lubrication: At least once a year, apply a small amount of acid-free grease or technical spray lubricant to all moving parts, especially the locking points and gears. This reduces friction and prevents wear.
- Inspection: Regularly check all screws and fasteners for tightness. Retighten if necessary, but do not overtighten. Inspect for any signs of wear, corrosion, or damage.
- Adjustment: If the window becomes difficult to operate or does not seal properly, minor adjustments to the locking points or hinges may be required. Refer to specific ToniTec instructions or consult a professional.
