4) After installation, check whether the switch is smooth up and down. If it is not smooth, check whether the window overlap is standard, whether there is debris on the hinge surface that needs to be lubricated, and the tightness can also be adjusted to the machine wire on the black wind resistance block in the middle , In order to achieve the appropriate effect of tightness!
