The dust on the doors and windows should be cleaned regularly to keep the doors, windows, glass and hardware clean and bright. 2.

The debris inside the frame should be cleaned in time to prevent the drainage channel from being blocked and causing poor drainage and water leakage. 4. When opening the doors and windows, the strength should be moderate, try to keep the speed even when opening and closing. 5, try to avoid hitting the door and window with a hard object or scratching the surface of the profile. 6. When it is found that the door and window are inflexible or other abnormal conditions during use, the reason should be found in time. If the customer cannot eliminate the fault, contact the door and window manufacturer and supplier so that the fault can be eliminated in time.
