"Duratec" Casting
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.
