6. When crimp is completed, remove the latch pin, open the yoke and remove the splice.
NOTE
If splice sticks in the die after crimping, apply a rocking action to the terminal to loosen it from the die. Wipe light oil on the
dies to prevent sticking, or spray dry lubricant.
7. To crimp the other half of splice, reposition un-crimped end of splice in the stationary die and follow
the same procedure used to crimp the first half of splice.
8. Inspect the crimp according to Section 5.
4.3. Crimping Splices with Step-Down Adapter
DANGER
Avoid personal injury. When operating tool or power unit, exercise caution while holding splice or wire near the crimping area.
1. Strip wires to the dimensions listed in Figure 3. DO NOT nick or cut the wire strands.
2. Select the proper splice, adapter, and crimping die for the wire size (see Figure 6).
*Note that the end of the splice containing the adapter has a different color code. Use the crimping die
for the larger wire size to crimp both ends of the splice. For example, use Crimping Die PN 1490598–
1 (for wire size 6 AWG) to crimp both ends of the splice with step-down adapter for stepping down
from wire size 6 to 8 AWG.

3. Insert stripped wire into the wire barrel of the end of the splice to be crimped until the wire bottoms
against the wire stop within the splice. Refer to Figure 3.
4. Remove crimping head latch pin and open yoke.
5. Place the splice in the stationary die. Grasp the end of the splice to be crimped and point the opposite
end toward the top of the head yoke at approximately a 30 degree angle. Rotate the end of the splice
to be crimped into the die. Position the edge of the window indent against the locator. Refer to Figure
5.
6. Holding the splice in place, close the yoke and insert the latch pin.
CAUTION
Be sure the latch pin is fully inserted, or damage to the dies and tool or head will occur when activated.
7. Holding the wire in place, activate tool or power unit to complete first wire barrel crimp.
8. When the crimp is completed, remove the latch pin, open the yoke and remove splice.
NOTE
If splice sticks in the die after crimping, apply a rocking action to the terminal to loosen it from the die. Wipe light oil on the
dies to prevent sticking, or spray dry lubricant.
9. To crimp the other half of splice, reposition un-crimped end of splice in the stationary die and follow
the same procedure used to crimp the first half of splice.
10. Inspect the crimp according to Section 5.
