How can a steel-steel pulley change it? Thank you!
The window is the top of the window frame with an anti-theft block first with a screwdriver to take down and then cover the edge of the window with a word screwdriver pry open down ... sash up the lift can be removed to replace the pulley simple Is two screws
First in the door on the cover to go down (in the material is the plane of the plane, with a flat screwdriver from the above or below the port pry open), and then lift the door up the whole, the following can be withdrawn from the track, After the pulley is changed, the door can be loaded in the reverse order. Hope you can understand.
