2. Make sure that the ratchet is released. Squeeze
the tool handles together and allow them to open
fully.
3. Looking straight into the back of the tool, insert
the terminal (insulation barrel first) into the front of
the crimp section. See Figure 3.
4. Position the terminal in th
e crimping area so that
the locator/insulation stop enters the locator slot in
the terminal.
5. Hold the terminal in this position and squeeze the
too
l handles together until the insulation anvil starts
entry into the insulation crimper. Do NOT deform the
insulation barrel or wire barrel.
6. Insert a properly-stripped wire through the wire
slot of
the locator and into the wire barrel of the
terminal until the wire insulation butts against the
locator/insulation stop.
7. While holding the wire in place, squeeze the tool
h
andles together until the ratchet releases.
8. Allow the tool handles to open fully and remove
the
crimped terminal.

4. MAINTENANCE/INSPECTION
4.1. Daily Maintenance
Remove all foreign particles with a clean, soft brush or
a clean, soft, lint-free cloth. Make sure the proper
retaining pins are in place and are 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.
Make sure 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 between the jaws, and store the tool
in a clean, dry area.
4.2. Periodic Inspection
Regular inspection should be performed by quality
control personnel. A record of scheduled inspections
should remain with the tool and/or be supplied to the
supervisory personnel responsible for the tool. Though
recommendations call for at least one inspection a
month, the inspection frequency should be based on
the amount of use, ambient working conditions,
operator training and skill, and established company
standards. These inspections should be performed in
the following sequence:
A. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the tool (handles partially closed) into a
suitable degreaser that will not affect paint or plastic
material.
2. Make certain all retaining pins are in place and
ar
e secured with the proper retaining rings. If
replacements are necessary, refer to Figure 5.
3. Close the tool handles until the ratchet releases,
an
d then allow the handles to open freely. If they do
not open quickly and fully, then the spring is
defective and must be replaced (see Section 5,
REPLACEMENT AND REPAIR).
4. Inspect the tool, with special emphasis on
chec
king for worn, cracked, or broken crimping
jaws. If damage to any part of the head is evident,
return the tool for evaluation and repair (see Section
5, REPLACEMENT AND REPAIR).
B. Crimp Height Inspection
Crimp height inspection is performed through the
use of a micrometer with a modified anvil,
commonly referred to as a crimp height comparator.
TE does not market crimp height comparators.
Refer to Instruction Sheet 408-7424 for detailed
information on obtaining and using a crimp height
comparator.
Refer to Figure 4.and proceed as follows:
1. Refer to the table in Figure 4 and select a
terminal and a wire (maximum size) for the hand
tool
.
2. Refer to Section 3, CRIMPING PROCEDURE,
a
nd crimp the terminal accordingly.
