6. MAINTENANCE AND INSPECTION PROCEDURE
TE Connectivity recommends that a maintenance and
inspection program be performed periodically to
ensure dependable and uniform terminations. Though
recommendations call for at least one inspection a
month, frequency of inspection 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 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.
6.1. 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.
6.2. 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 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 7, REPLACEMENT AND
REPAIR.
2. Inspect head assembly for worn, cracked, or
broken jaws. If damage is evident, return the tool
to TE for evaluation and repair. See Section 7,
REPLACEMENT AND REPAIR.
C. Crimping Die Closure Inspections
Each tool is inspected for proper die closure before
shipment. However , inspection of die closure for
excessive wear is required periodically.
This inspection requires the use of plug gages
conforming to the dimension shown in Figure 5. TE
does not manufacture or market these gages.
To gage die closure, refer to Figure 6 and proceed as
follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
2. Close the tool handles until the wire barrel dies
are bottomed. Do not apply additional pressure to
the tool handles.
3. With wire barrel dies bottomed, inspect the wire
barrel crimp die closure using the proper plug
gage. Press the spring--loaded locator down and
hold gage in alignment with the die closure.
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 6.
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 6.
6. Insert tool insulation crimping adjustment pin
into Position 1.
7. With crimping dies bottomed, check the
insulation barrel section of the crimping chamber
as described in Steps 4 and 5.
If the crimping chamber conforms to the gage
inspection, the tool is considered dimensionally
correct, and should be lubricated with a THIN coat of
any good SAE 20 motor oil. If not, the tool must be
returned to TE for further evaluation and repair . Refer
to Section 7, REPLACEMENT AND REPAIR.
For additional information regarding the use of plug
gages, refer to Instruction Sheet 408--7424.
