   Note: Make sure that the wedge and the clamp are installed correctly. Refer to illustrations 4 and 5.

   Note: Make sure that length (T) of the dead end of the wire rope is a minimum of six rope diameters and make sure that length (T) is not less than 150 mm (6 inch).

4. Use a hammer to seat the wedge and the wire rope into the socket as deep as possible prior to applying the first load.

5. Apply the first load in order to seat the wedge and the wire rope in the socket. This load should be equal or greater than the loads that are expected during normal use.
