With the introduction of "Duratec", selfthreading screws have been used to mount many of the parts and
assemblies to the structure. If is important that when replacing these screws, they be threaded into the
original screw threads. The proper procedure for doing this is to insert the screw into the hole and turn the
screw counterclockwise until the screw can be felt to "drop" in place. An audible "click" may also be heard.
Once the screw is properly in place, it may then be tightened.
