What is meant by caring for windows?

1) caring for balcony and window fittings — lubrication, as well as adjusting the mechanical part responsible for opening. This process needs to be carried out from one to two times a year. First you need to apply a lubricant to fittings, and then close the window and twist the handle, giving it different positions, so that the lubricant is evenly distributed around the entire perimeter of the mechanism. It is important to remember that turning the handle is carried out only when the leaps are closed.
