The solution is as follows:
1. After opening, remember that when the positioner (also called wind brace) reaches a fixed position, it is forbidden to pull or push hard. Improper use may easily cause the positioner to bend or break. The locator button push-button must be pressed.
2. When opening the window horizontally, remember not to turn the handle upward and open the overhang at the same time. Improper operation may easily damage the hardware parts.
3. Regularly break the bridge aluminum doors and windows to clear the debris between the draft vents to prevent the water outlet from blocking or accumulating water. The handle is locked downwards, 90 degrees is inwardly opened, and upwards is inwardly collapsed. Check to see if there is a problem with the hardware installation, especially the rack linkage needs to be in the same direction.
