Its functions

It is necessary to check the uniformity of the working course of the rollene during lifting and lowering. Follow the lifting limiter that should stop lowering the canvas as soon as it touches the restrictive plate, otherwise the structure can jam. In winter, before each lifting of the canvas, make sure that there is no icing. If the ice crust has formed, then try to free the canvas from it with light blows of your hand. Otherwise, the system will not be able to correctly perform its functions.
