j)Position the cable boot and strain relief on the cable so it fits in cable handle cavity and lock the strain relief in place by pushing the two halves together.

k)Assemble cable in left side of gun handle. Assemble trigger into the proper handle cavity.(For K1723 also assemble the rocker switch in the groves provided in the handle.) Assemble right side of gun handle and tighten the screws that hold the handle together. (See Figures E.5 and E.6).

WIRE FEEDER END REPAIR (K575 AND

K1723) (See Figure E.7).

a)Remove the cable liner per previous instructions.

b)Loosen the boot nut. Slide the boot nut and boot toward the middle of the cable past the damaged section.

c)Rotate the collar nut until the screw anchoring the cable handle is visible. Remove the screw and save it.

d)Slide the cable handle and collar nut toward the middle of the cable past the damaged section. Remove the strain relief housing from the strain relief and slide both toward the middle of the cable past the damaged section. On older cables remove and save the cable clamp that was used in place of the strain relief.

NOTE: If sliding the cable handle becomes difficult, try rotating it 180°.

e)Remove incoming connector from cable by unscrewing connector nut from incoming connec- tor. If the cable inner tube is difficult to remove from the connector assembly, carefully slit it length- wise with a knife up to the brass connector.

f)Cut the cable control wires where they meet the cable jacket or else unsolder the connection where they connect to the terminal lead assembly. If you cut the wires, strip the cut end 1/4 inch (6.4 mm) from the end.

g)Cut off the damaged section of cable and strip off the outer jacket as shown in Figure E.3. Be careful not to cut the insulation on the control wires while stripping jacket. Strip all four control leads 1/4 inch (9.5 mm) from the end.

h)Check that the cable boot, boot nut, cable handle, collar nut, strain relief, and strain relief housing are on the cable. Slip the connector nut over the cop- per strands with the threaded end out. Orient the connector assembly so the red and white control leads will have the straightest possible routings to the sockets on the back side of the connector. Assemble the incoming connector to the cable by forcing the steel tube of the connector into the inside diameter of the cable inner tube until the copper strands are butted against the incoming connector shoulder. Keeping the copper strands against the shoulder, pull the connector nut over the copper strands, engage the incoming connec- tor threads, and tighten in place. Refer to Figure E.4.
