dies and the terminal wire barrel rests against the
locator. See Figure 3.
5. Insert the stripped wire into the terminal wire
barrel. The end of the wire must be flush with, or
extend beyond, the edge of the wire barrel.

6. Close the crimping head yoke and insert the
latch pin.
CAUTION
!
To avoid damage to the yoke, latch pin, or die
assembly, make sure that the latch pin is fully
inserted.
7. Hold terminal in position and activate power unit
to complete the crimp. Open the crimping head
yoke and remove the crimped terminal from the
dies.
NOTE
i
If the terminal sticks in the dies after crimping,
use a rocking motion on the terminal to release it
from the die.
2. Hold the stationary insulation crimping die
against the pin--key to prevent the pin--key from
popping back out. Tighten the socket head cap
screws. Similarly, adjust the moving insulation
crimping die.
NOTE
i
Always adjust both pin- keys in the same
position.
3. Crimp a terminal to the wire, as described in
Section 3, CRIMPING PROCEDURE.
4. Remove the terminal from the crimping dies and
bend the wire back and forth once. The terminal
should retain its grip or support on the wire. If the
insulation crimp does not grip or support the wire
insulation, position the pin--keys in the next tighter
position and repeat the crimping procedure.
NOTE
i
AMPLI- BOND terminals contain a wire insulation
“grip” and PLASTI- GRIP terminals contain a wire
insulation “support.”
5. Repeat Steps 1 through 4 until the desired
insulation grip, or support, is obtained. DO NOT
use a tighter setting than is required.
5. MAINTENANCE AND INSPECTION
Tyco Electronics recommends that a maintenance
and inspection program be performed periodically to
ensure dependable and uniform terminations. The die
assembly should be inspected once a month.
Frequency of inspection should be adjusted to suit
your requirements through experience.

8. Check the termination to ensure the terminal
retains a grip on the wire. If an adjustment to the
insulation crimp is necessary, refer to Section 4,
INSULATION CRIMP ADJUSTMENT. Refer to
Figure 4 for a properly crimped terminal.
4. INSULATION CRIMP ADJUSTMENT
The insulation barrel crimping dies have three
positions: 1—Tight; 2—Medium; and 3—Loose.
1. Loosen the socket head cap screws on the
stationary die, then push the pin--key all the way in
for the loose position.
