4. Perform a test crimp as described in Section 3,
Step 6. Remove the crimped terminal or splice and
check the insulation support. Bend the wire back
and forth once. The insulation barrel sleeve should
retain grip on the wire insulation. If the wire pulls
out, move the insulation crimping adjustment pins to
the next tighter position (Position 2) and proceed to
Step 5. If the wire does not pull out, the pins are
properly adjusted and the tool is ready for crimping.
5. Perform another test crimp as described in
Step 4. Adjust pins, as necessary, until the desired
insulation grip is obtained. Do not use a tighter
setting than is required.
The insulation crimping adjustment pins must be
NOTE
located in the same adjustment position.

5. MAINTENANCE AND INSPECTION PROCEDURE
It is recommended that a maintenance and inspection
program be performed periodically to ensure
dependable and uniform terminations. Frequency of
inspection should be adjusted to suit your
requirements through experience and depends on:
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 and calibrated before being
shipped; however, it is recommended that the tool be
inspected immediately upon arrival to ensure that the
tool has not been damaged during shipment.
5.1. Daily Maintenance
1. The 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.
5.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Rev S
•
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.
5.3. Visual Inspection
1. Close tool handles until ratchet releases and then
allow them to open freely. If they do not open
quickly and fully, the spring is defective and must be
replaced. See Section 6, REPLACEMENT AND
REPAIR.
2. nspect head assembly for worn, cracked, or
broken jaws. If damage is evident, return the tool for
evaluation and repair. Refer to Section 6,
REPLACEMENT AND REPAIR.
5.4. Gaging the Crimping Chamber
This inspection requires the use of plug gages
conforming to the dimensions provided in Figure 7. TE
does not manufacture or market these gages.
To gage the crimping chamber, proceed as follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gages.
2. Remove locator assembly.
DO NOT lose spring in locator assembly.
CAUTION
!
3. Close the tool handles until the crimping jaws
have bottomed. Do NOT force jaws beyond initial
contact.
4. Align the GO element with the wire barrel section
of the crimping chamber. Push element straight into
the crimping chamber without using force. The GO
element must pass completely through the crimping
chamber. See Figure 8.
5. Align the NO-GO element and try to insert it
straight into the same section of the crimping
chamber. The NO-GO element may start entry, but
must not pass completely through the crimping
chamber. See Figure 8.
6. Re-install locator assembly.
7. Insert tool insulation crimping adjustment pins
into Position 1.
8. With crimping jaws bottomed, check the
insulation barrel section of the crimping chamber as
described in Steps 4 and 5.
