4. CRIMPING PROCEDURE
1. Refer to the table in Figure 2, select a wire of
the specified size and strip the wire to the
dimension provided. Do NOT nick or cut the wire
strands.
2. Select an applicable contact. See Figure 2.
3. Hold the tool so that the front of the tool is
facing you.
4. Make sure that the ratchet is released.
Squeeze the tool handles together and allow
them to open fully.
5. Rotate the blue plastic locator stop index to the
appropriate position.
• When crimping a 110 series terminal, rotate the
index until the number “110” appears in the
uppermost position.
• When crimping a 187 or 250 series terminal,
rotate the index until the numbers “250-187” appear
in the uppermost position.
6. Insert the terminal into the proper crimp
section. In-line terminals may be crimped in either
in-line section. Flag terminals must be crimped in
the flag crimp section. See Figure 4.
• For in-line terminals, the flat side of the terminal
must seat on the locator.
• For flag terminals, the flat side of the wire end
must face outward and the mating end must seat on
the locator.
7. Squeeze the tool handles sufficiently to hold
the terminal firmly in place without deforming it.
8. Insert a properly stripped wire into the barrel of
the terminal.
9. Hold the wire in place and squeeze the tool
handles until the ratchet releases.
10. Allow the tool handles to open fully, and
remove the crimped terminal.
5. MAINTENANCE/INSPECTION
5.1. Daily Maintenance
Remove all foreign particles with a clean, soft brush or
a clean, soft, lint-free cloth. Do NOT use materials or
objects that can damage the dies. If foreign matter
cannot be removed easily, or if the proper replacement
parts are not available, return the dies to your
supervisor.
Make certain the dies are protected with a THIN coat
of any good SAE 20 motor oil. DO NOT OIL
EXCESSIVELY.
When the dies are not in use, mate and store them in
a clean, dry area.
