This component is designed as a replacement part for GPM systems and is suitable for both wooden and plastic windows. Please read these instructions carefully before proceeding with installation or maintenance.
Setup and Installation
The Winkhaus GRM 1793920 is a replacement part for window gearing. Installation should be performed by a qualified professional to ensure proper function and safety. Incorrect installation can lead to damage to the window or the transmission mechanism.

- Removal of Old Transmission: Carefully remove the screws securing the old transmission. Detach the old transmission from the window sash.
- Inspection: Inspect the window sash for any damage or wear that might affect the new transmission's function.
- Positioning the New Transmission: Place the new Winkhaus GRM 1793920 transmission into the designated channel on the window sash. Ensure it aligns correctly with all fixing points.

Operation
The Winkhaus GRM 1793920 transmission operates in conjunction with your window handle to control the opening, tilting, and locking functions of the window. Ensure the handle moves freely and engages the transmission without excessive force.
- Closed Position: When the window is closed and the handle is in the downward position, the transmission engages the locking points, securing the window.
- Open Position: Turning the handle 90 degrees to the horizontal position disengages the locking points, allowing the window to be opened.
- Tilt Position (if applicable): For tilt-and-turn windows, turning the handle 180 degrees upwards from the closed position allows the window to tilt inwards for ventilation.
If you experience stiffness or difficulty operating the window, refer to the Maintenance or Troubleshooting sections.
Maintenance
Regular maintenance ensures the longevity and smooth operation of your Winkhaus GRM 1793920 window transmission. The product includes ToniTec maintenance instructions for autopilot systems, which should be followed for optimal performance.
Recommended Maintenance Schedule:
- Lubrication: Annually, apply a suitable, non-acidic lubricant to all moving parts of the transmission, including the gearing mechanism and locking points. This helps prevent wear and ensures smooth operation.
- Cleaning: Periodically clean any visible dirt or debris from the transmission mechanism. Use a soft cloth and avoid abrasive cleaners.
- Inspection: Regularly inspect the transmission for signs of wear, corrosion, or damage. Check that all screws are tight.
