D-2 MAINTENANCE D-2
NOTE: The cable contains three control leads. Any
two control leads can be used, provided the two
colors used are the same at both ends. The extra
lead is a spare that can be used if one of the other
leads breaks.
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 connec-
tor threads, and tighten in place. Refer to Figure 3.
NOTE: For best results, insert a .175”/.197” (4.5/
5.0 mm) 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 procedure ensures the inner core does
not kink while assembling or tightening.
h. Pull the cut-off lead terminals off the trigger assem-
bly and connect the replacement control lead ter-
minals.
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.
