4. CRIMPING PROCEDURE
1. Strip wires to dimensions specified on instruction sheet packaged with dies.
2. Insert terminal or splice in stationary die according to instruction sheet packaged with dies.
CAUTION
Ensure latch pin is fully inserted before operating hand tool.
3. Pump moveable lever until moving die grips terminal or splice.
CAUTION
Do not deform wire barrel of terminal or splice.
4. Insert stripped wire into wire barrel of terminal or splice.
5. Continue pumping moveable lever. A slight click may be heard, indicating the pump has shifted into
the high-pressure stage. Continue pumping moveable lever. When dies have bottomed, an audible
“pop” will be heard. This indicates that the crimp is complete.
6. Retract moveable die by opening the movable handle to the full open position, turn the movable
handle (to actuate striker). DO NOT TURN THE MOVABLE HANDLE WHILE IN THE CLOSED
POSITION AS YOU WILL DAMAGE THE PLUNGER (PRESSURE RELEASE), compress handles to
depress plunger (pressure release). Movable die will now retract. See Figure 1.
7. Remove latch pin, open yoke, and remove crimped terminal or splice.
NOTE
If terminal or splice sticks in die after crimping, apply a rocking motion action to remove it from the die.
8. Inspect crimped terminal or splice according to inspection procedure on instruction sheet packaged
with the dies.
5. MAINTENANCE/INSPECTION
These instructions have been approved by TE Connectivity Design, Production, and Quality Control Engineers
to provide documented maintenance and inspection procedures. Through test laboratories and the inspection
production assembly, the procedures described herein have been established to ensure quality and reliability of
TE crimping tools.
Each crimping tool is assembled and inspected before shipment. TE recommends that the tool be inspected
immediately upon its arrival at your facility, and at regularly scheduled intervals, to ensure the tool has not been
damaged during handling and use. Frequency of inspection depends upon the following: care, amount of use,
and handling of the tool; type and size of products crimped; degree of operator skill; and environmental
conditions.
DANGER
Make sure hydraulic pressure is released before following maintenance and inspection procedures, unless otherwise specified
in the procedure.
5.1. Cleaning
It is recommended that each operator of the tool be made aware of, and responsible for, the following steps:
1. Remove all foreign particles with a clean, soft brush or clean, soft lint-free cloth. DO NOT use hard or
abrasive objects that could damage the tool. Make sure the proper retaining pins are in place and
secured with the proper retaining rings. If foreign matter cannot be removed easily, or if the proper
replacement parts are not available, return the tool to your supervisor.
2. Make certain all pivot points and bearing surfaces are protected with a THIN coat of any good SAE 20
motor oil. Do not oil excessively. When the tool is not in use, keep the handles closed to prevent
objects from becoming lodged in the crimping chamber, and store the tool in a clean, dry area.
5.2. Hydraulic Fluid Level Inspection (Figure 2)
Remove tool from bench mount; then proceed as follows:
1. Turn tool upside down and clamp it in a vise so that tool handles are in an upright position.
