1. The care, amount of use, and handling of the
hand tool.
2. The presence of abnormal amounts of dust and
dirt.
3. The degree of operator skill.
4. Your own established standards.
The hand tool is inspected before being shipped;
however, TE recommends that the tool be inspected
immediately upon arrival to ensure that the tool has
not been damaged during shipment.
4.1. Daily Maintenance
1. Hand tool should be immersed (handles partially
closed) in a reliable commercial degreasing
compound to remove accumulated dirt, grease, and
foreign matter. When degreasing compound is not
available, tool may be wiped clean with a soft, lint-
free cloth. Do NOT use hard or abrasive objects that
could damage the tool.
2. Make certain that the retaining pins are in place
and that they are secured with retaining rings.
3. All pins, pivot points, and bearing surfaces should
be protected with a THIN coat of any good SAE 20
motor oil. Do not oil excessively.
4. When the tool is not in use, keep handles closed
to prevent objects from becoming lodged in the
crimping jaws. Store the tool in a clean, dry area.
4.2. Periodic Inspection
A. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tool used in daily production - lubricate daily
Tool used daily (occasional) - lubricate weekly
Tool used weekly - lubricate monthly
Wipe excess oil from tool, particularly from crimping
area. Oil transferred from the crimping area onto
certain terminations may affect the electrical
characteristics of an application.
B. Visual Inspection
1. Close tool handles until ratchet releases. Open
tool handles completely.
This tool does not have a return spring to open the
handles.
2. Inspect head assembly for worn, cracked, or
broken jaws. If damage is evident, return the tool for
evaluation and repair. See Section 6,
REPLACEMENT AND REPAIR.
C. Gaging the Crimping Chambers
This inspection requires the use of a plug gage
conforming to the dimensions provided in Figures 4
and 5. TE does not manufacture or market these
gages. To gage the crimping chamber, proceed as
follows:
Inspecting Center Contact Dies
Plug gaging of the center contact crimping dies
requires the use of two separate gages, which can be
used in all 220015-[ ] tools. One gage is used inside
the radius of the die closure; the other is used
between the indent forming sections. Refer to Figure 4
and proceed as follows:
1. Close the tool handles until crimping dies are
bottomed. Do NOT apply additional pressure, or
ratchet will release.
2. With dies bottomed, check the indent-forming
closure by using the box-type plug gage shown in
Figure 4, Detail A. Align the GO element with the
contact crimping chamber and insert the element
without using force. The GO element must pass
completely through the die closure.
3. Now align the NO-GO element and try to insert it
straight into the same crimping chamber. The NO-
GO element may start entry but must NOT pass
completely through as shown in Figure 4.
4. Continue to hold the dies bottomed and insert the
second (grooved) gage to inspect the radius of the
dies, as shown in Figure 4, Detail B. Use the same
method described in Steps 2 and 3.
5. If the die closure meets both plug gage
conditions, the dies may be considered
dimensionally correct.
Inspecting Braid and Braid Gap Crimping Dies
Figure 5 provides proper plug gage dimensions -
according to tool dash number - for both the braid and
the braid gap crimping areas. Figure 5 shows the
location of both crimping areas for inspection. Proceed
as follows:
1. Remove all traces of oil and dirt from tool
crimping areas and gages.
2. Close tool handles until dies are bottomed, but
not under pressure.
3. Using the proper plug gage, check the braid and
the braid gap closure with dies bottomed. Hold gage
in straight alignment with the dies and carefully try
to insert, without forcing, first the GO element, and
then the NO-GO element. The GO element must
pass completely through the crimp die closure. The
gage for the braid die will butt against the braid gap
crimp die.
