6. CRIMPING PROCEDURE

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.

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.
