3. Setup and Installation
Installation of window gear mechanisms requires precision. If you are unsure about any step, it is recommended to consult a qualified professional.
3.1 Safety Precautions
- Always wear appropriate personal protective equipment, such as safety glasses.
- Ensure the window sash is securely supported during removal and installation to prevent accidental falls.
- Disconnect any electrical components if working near automated window systems.
3.2 Tools Required
- Screwdriver set (Phillips and flathead)
- Measuring tape
- Pencil or marker
- Pliers (optional, for stubborn screws)
3.3 Installation Steps
- Remove Old Gear: Carefully remove the existing window gear mechanism. Note the position and orientation of all components.
- Measure and Verify: Compare the new Winkhaus GRM 1793831 gear with the old one to ensure it is the correct replacement part. Verify the sash rebate height (FFH) is within the 800-1300 mm range.
- Position New Gear: Place the new gear into the designated channel within the window sash. Ensure it sits flush and aligns correctly with all connection points.
- Secure Gear: Fasten the gear using appropriate screws. Do not overtighten.
- Connect Rods: Attach any connecting rods or extensions to the gear mechanism as per the original configuration.
- Test Operation: Before fully closing the window, test the gear's function by operating the window handle. Ensure smooth movement and proper engagement of all locking points. Adjust if necessary.
4. Operating Instructions
The Winkhaus GRM 1793831 window gear facilitates the opening, closing, and locking of your window via the window handle. The operation is standard for most modern window systems:
- Closed/Locked Position: When the handle is in the downward position, the window is closed and locked.
- Tilted Position (if applicable): Turning the handle to a horizontal position (90 degrees) typically allows the window to tilt inwards for ventilation.
- Open Position: Turning the handle upwards (180 degrees) allows the window to fully open inwards.
Always operate the handle smoothly and without excessive force. If the handle feels stiff, do not force it, as this may damage the gear or other window components.
5. Maintenance
Regular maintenance ensures the long-term functionality and security of your window gear. Refer to the included ToniTec Autopilot maintenance manual for detailed instructions specific to Winkhaus activPilot systems.
5.1 General Maintenance Tips
- Cleaning: Periodically clean the visible parts of the gear and the window frame channels to remove dust and debris. Use a soft cloth and mild cleaning agents.
- Lubrication: Lubricate all moving parts, such as hinges, locking points, and the gear mechanism, at least once a year. Use a non-resin-forming oil or a specialized window hardware lubricant. Avoid using grease or oils that can attract dirt.
- Inspection: Regularly inspect the gear and other window hardware for signs of wear, damage, or loose screws. Tighten any loose screws immediately.
6. Troubleshooting
If you encounter issues with your window gear, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Window difficult to open or close | Lack of lubrication, debris in mechanism, misalignment of sash | Clean and lubricate all moving parts. Check for obstructions. Adjust window sash alignment if necessary. |
| Window handle is stiff or hard to turn | Lack of lubrication, bent component, internal gear issue | Apply lubricant to the handle mechanism and gear. Inspect for bent or damaged parts. If the problem persists, professional inspection may be required. |
| Window does not seal properly when closed | Misalignment of locking points, worn gaskets, sash sag | Check alignment of locking points and adjust if possible. Inspect gaskets for wear and replace if needed. Address sash sag if present. |
| Window makes grinding noises | Debris in gear, lack of lubrication, damaged components | Clean the gear mechanism thoroughly. Lubricate all moving parts. If noise persists, inspect for damaged internal components. |
