8. To complete the crimp, close the handles until
the ratchet releases. Allow the tool handles to
open fully and remove the crimped terminal or
splice.
9. To crimp the other half of a butt splice,
reposition the uncrimped side in the tool and
repeat Steps 6 through 8.
4. MAINTENANCE AND INSPECTION PROCEDURE
Tyco Electronics recommends that a maintenance
and inspection program be performed periodically to
ensure dependable and uniform terminations.
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, Tyco Electronics 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. 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.
4.2. Periodic Inspection
A. Lubrication
1. 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
jaws.Visual Inspection
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 5,
REPLACEMENT AND REPAIR.
2. Inspect head assembly for worn, cracked, or
broken jaws. If damage is evident, return the tool
to Tyco Electronics for evaluation and repair.
See Section 5, REPLACEMENT AND REPAIR.
C. Gaging the Crimping Chamber
This inspection requires the use of three plug gages -
- one for each crimping chamber in the tool. The
gages should conform to the dimensions listed in
Figure 4.
Tyco Electronics does not manufacture or market
these gages. Refer to 408-7424 for information about
the plug gages.
To gage a crimping chamber, refer to Figure 5 and
proceed as follows:
1. Close the tool handles until the jaws bottom,
then hold the tool in this position. Do NOT force
the dies beyond initial contact.
2. Align the GO element of the proper gage with
the corresponding crimping chamber, as shown
in Figure 5. Push the element straight into the
crimping chamber without using force. The GO
element must pass completely through the
crimping chamber.
3. Now align the crimp gage 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.
4. Use the two other plug gages to inspect the
remaining crimping chambers, as described in
Steps 1 through 3 above.
If the crimping chambers conform to the gcorrect
and should be lubricated with a THIN coat of any
good SAE 20 motor oil. If not, the tool must be
returned to Tyco Electronics for further
evaluation and repair.
For additional information regarding the use of a
plug gage, refer to instruction sheet 408-7424.
D. Ratchet Inspection
The CERTI-CRIMP tool ratchet feature on this hand
tool should be checked to ensure that the ratchet
does not release prematurely, allowing the jaws to
open before they have fully bottomed. Obtain a 0.025
[.001] shim that is suitable for checking the clearance
between the bottoming surfaces of the crimping
jaws..
