1. Remove the gas nozzle and nozzle insulator, if
used, to locate the set screw in the gas diffuser
which is used to hold the old liner in place. Loosen
the set screw with a 5/64" (2.0 mm) Allen wrench.
2. Remove the gas diffuser from the gun tube.

3. Lay the gun and cable out straight on a flat surface. Loosen the set screw located in the brass connec- tor at the feeder end of the cable and pull the liner out of the cable.

4. Insert a new untrimmed liner into the connector end of the cable. Be sure the liner bushing is sten- cilled appropriately for the wire size bing used.

5. Fully seat the liner bushing into the connector. tighten the set screw on the brass cable connector. the gas diffuser, at this time, should not be installed onto the end of the gun tube.

6. With the gas diffuser still removed from the gun tube, be sure the cable is straight, and then trim the liner to the length shown in Figure D.1. Remove any burrs from the end of the liner.
