Menus are sometimes hierarchically organized, allowing navigation through different levels of the menu structure. Selecting a menu entry with an arrow will expand it, showing a second menu (the sub-menu) with options related to the selected entry.
Torsion springs are normally mounted horizontally above the opening of your garage door. When you pull the door down, cables attached to the bottom corners actually force the springs to wind up, in turn energizing the system.
4.4 Take the spring on the left and place it at the left end of the door as pictured here. Notice that the end of the wire points to the right toward the center of the door. This is a right wind torsion spring. It will go above the garage door on the left side of the spring anchor bracket.therwise, after winding the torsion springs, you will need to stretch the springs and secure the winding cone. First, mark the shaft 1/4 beyond the winding cone with tape or with a file. We stretch the springs because the shaft floats horizontally between the flexible end bearing plates as the garage door operates.
