4. Slowly close the tool head, making sure the
contact remains properly positioned in the nest. If
the contact is cocked or otherwise out of line,
re–align it before proceeding. The contact should
remain in the nest as shown in Figure 3. DO NOT
deform the wire barrel.
5. Crimp the contact by squeezing the tool
handles. Then tighten screws of the hold–down
device and contact locator. If the contact crimp is
straight and the wire barrel has not been damaged,
the tool is ready to use.
Ifthe tool has been preset for wire size 10 AWG
Ċthe smallest wire sizeĊno further adjustment is
necessary, even though wire size 8 or 6 AWG is
to be terminated; the setting for wire size 10 will
also accommodate wire size 8 or 6. However, if
the anvil die is not set for wire size 10 and wire
size 8 or 6 is desired, then the anvil die should be
set to the appropriate wire size ofeither 8 or 6.
6. If the wire size marking is positioned for a wire
size other than desired, depress the anvil die
spring–loaded indexing pin and rotate the anvil die
until the desired size appears. Then release the
indexing pin and allow locator pin to snap into the
hole which locks the anvil die in place for the
desired size.
7. Open the tool head, and position the contact in
the nest, locating the outer end of the wire barrel
(wire–entry end) so that it extends from the nest
area between 0.76 to1.02 [.030 to .040] as shown
in Figure 4.

8. Close tool head just enough to retain the
contact; then insert the wire into the wire barrel,
making sure the wire does not extend beyond the
wire barrel. See Figure 5.

9. Slowly squeeze the handles, making sure
contact remains aligned properly in the nest. It may
be necessary to open the handles slightly, allowing
the contact to be re–adjusted in the nest. Continue
to squeeze the handles to complete the crimp.
4. CRIMP INSPECTION
Inspected the crimped contact according to Figure 6.
Poorly crimped contacts can be avoided through
careful use of these instructions.
