DANGER
To avoid personal injury, release the hydraulic
pressure to the hose. Disconnect electric
hydraulic pump unit from power supply.

1. Depress the latch and open the crimping head
as shown in Figure 2.
2. While the head is open, pull back the nest wheel
lock and turn the thumb knob until the desired nest
appears. Wire size numbers appear at each nest.
3. Rotate the thumb knob left or right until the nest
wheel locks into place. If thee nest wheel is not
properly locked, the head cannot be closed.

Do not use wires with nicked or missing
conductor strands.
6. CRIMPING PROCEDURE
DANGER
To avoid personal injury, release the hydraulic
pressure to the hose. Disconnect electric
hydraulic pump unit from power supply.
1. Center the terminal or splice wire barrel in the
nest as shown in Figure 4. For best results,
position the brazed seam on the terminal or splice
toward the indenter.
NOTE
i
Wire size stamped on the terminal or splice must
correspond to the wire size stamped in the nest.
2. Activate the power unit to advance the indenter
and hold the terminal or splice in place. Do not
deform the wire barrel of the terminal or splice.
3. Insert the stripped wire into the wire barrel of
terminal or splice. When crimping terminals and
parallel splices, the end of the wire must be flush
with or extend slightly beyond the end of the wire
barrel. When crimping butt splices, wire must be
visible through the inspection hole.
4. Activate the power unit to complete the crimp.
5. To complete the other half of the butt splice,
remove and reposition uncrimped half of the splice
in the nest. Insert wire and then activate the power
unit to crimp the splice. The completed terminal or
splice should be as shown in Figure 5.
