g)Check that the cable boot and both halves of the strain relief are on the cable. Slip the connector nut over the copper strands with the thread end out. Orient gun tube connector so machined flat is on the same side of the cable as the red and white control leads. Assemble gun tube connector to 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 gun tube

connector shoulder. Keeping the copper strands against the shoulder, pull the connector nut over the copper strands, engage the gun tube connector threads, and tighten in place. (See Figure E.3).

NOTE: For best results, insert a .219"/240" (5.6/6.1mm) diameter rod through the connector and into core of cable approximately 5.00" (127 mm) when pushing the connector tube into the cable core tube. To tighten, hold the connector in place while turning the nut, then remove the rod from the core. This pro- cedure assures the inner core does not kink while assembling or tightening.

h)For K574:

Pull the cut-off lead terminals off the trigger assem- bly and connect the replacement control lead ter- minals. (See Figure E.4).
