splices until end of wire is flush with or extended
slightly beyond end of wire barrel as shown in
Figure 4C.
13. To complete crimp, close the handles until the
CERTI-CRIMP hand crimping tool ratchet control
releases. Handles can now be opened and the
crimped splice may be removed.
14. To crimp the other half of the butt splice,
remove it and re-position uncrimped half in nest.
Follow the same procedure used to crimp the first
half of the splice.
15. Refer to Section 3 and Figure 5 for splice crimp
inspection procedures.
3. CRIMP INSPECTION
Inspect crimped terminals and splices by checking the
features described in Figure 5. Use only the terminals
and splices that meet the conditions shown in the
“ACCEPT” column. “REJECT” terminals and splices
can be avoided through careful use of instructions in
Section 2 and by performing regular tool maintenance
as instructed in Section 4.
4. MAINTENANCE/INSPECTION PROCEDURE
TE Connectivity recommends that a maintenance/
inspection program be performed periodically to
ensure dependable and uniform terminations. Tools
should be inspected at least once a month. Frequency
of inspection may be adjusted to suit your
requirements through experience. Frequency of
inspection is dependent upon:
• The care, amount of use, and handling of the
tool
• The type and size of the products crimped
• The degree of operator skill
• The presence of abnormal amounts of dust and
dirt
• Your own established standards
All tools are inspected and calibrated before
packaging. Since there is a possibility of tool damage
in shipment, new tools should be inspected in
accordance with Section 4 when received in your
plant. Due to the precision design, it is important that
no parts of these tools be interchanged except those
replacement parts listed in Figure 9.
4.1. Cleaning
The tool should be immersed (handles partially
closed) in degreasing compound to remove
accumulated dirt, grease, and foreign matter. Remove
remaining degreasing compound with a lint free cloth.
When degreasing compounds are not available, tool
may be wiped clean with a lint-free cloth. Relubricate
tool, as instructed in Paragraph 4.3, before placing it
back in service.
4.2. Visual Inspection
1. Inspect the tool for missing pins or retaining
rings. If parts are missing or defective, refer to
Figure 9 for customer replaceable parts.
2. Inspect the die closure surfaces for flattened,
broken, or chipped conditions. Although dies may
gage within permissible limits, worn or damaged die
closure surfaces are objectionable and can affect
the quality of the crimp. Examples of possible
damaged die closure surfaces are shown in
Figure 6.

4.3. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with a good grade S.A.E. No. 20 motor oil as follows:
• Tools used in daily production - Lubricate daily
• Tools used daily (occasional) - Lubricate weekly
• Tools 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.
4.4. Die Closure Inspection
Each tool is inspected for proper die closure before
packaging. An inspection should be performed
periodically to check the tool die closure for excessive
wear.
The die closure inspection is accomplished using a
GO/NO-GO plug gage. TE neither manufactures nor
sells plug gages. Suggested design and GO/NO-GO
dimensions for the plug gage members are listed in
Figure 7. The following procedure is recommended for
inspecting the die closure.
