Pay attention to put the gauze away before closing the window when it is windy and rainy. If the gauze floats out due to strong wind, it should be put back on the track before pulling the screen window. When the wind is strong, the window should be closed or the screen window should not be used to prevent the screen window from being damaged by strong wind. During the use of the gate, the net should be pulled parallel to the gate track. If you pull the mesh out of the track, you should first put the mesh into the track obliquely, and then gently pull it several times, and pay attention to whether the mesh rolls back horizontally during the pulling process. In order to protect the metal profile of the gate, it is not allowed to trample the metal profile forcibly during use. If the frame and grid of the gate are worn, you can beautify the gate by Bellevue or self-painting. When the gauze doors and windows outside the sluice are not used for a long time, the gauze can be put away to avoid the spring of the gauze doors and windows losing elasticity and polluting the gauze.
