3. CRIMPING PROCEDURE
Each hand tool is coated with a preservative to
prevent rust or corrosion. Wipe this preservative
from the tool, particularly from the crimping jaws,
before using the tool.
Refer to the chart in Figure 2 and select wire of
desired size (within the range of the tool being used).
Strip the wire to the length indicated. Do NOT cut or
nick the wire strands.
Select the appropriate PLASTI–GRIP splice (refer to
Catalog 82042 for desired size and part number).
Refer to Figure 2 and Figure 3 and proceed as
follows:
1. Open the tool’s jaws by squeezing the handles
until the ratchet releases and then allow the
handles to open FULLY.
2. Insert stripped wires into both ends of the splice.
3. Center splice (with wires inserted) in crimper
jaws.
4. To complete crimp, close handles until ratchet
releases. Allow handles to open FULLY. Crimped
splice may be removed.

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 its arrival at your
facility to ensure that the tool has not been damaged
during shipment. Due to the precision design, it is
important that no parts of these tools be interchanged
except those replacement parts listed in Figure 7.
4.1. Daily Maintenance
1. Remove dust, moisture, and other contaminants
with a clean brush, or a soft, lint–free cloth. Do
NOT use 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 No. 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 dies. Store the tool in a clean, dry area.
4.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 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.
4.3. Periodic Inspection
1. Hand tool should be immersed (handles partially
closed) in a reliable commercial degreasing
compound to remove accumulated dirt, grease,
and foreign matter.
2. 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.
3. Inspect head assembly for worn, cracked, or
broken dies. If damage is evident, return the tool to
Tyco Electronics for evaluation and repair. See
Section 5, REPLACEMENT AND REPAIR.
4.4. Crimping DieClosureInspection
This inspection requires the use of plug gages
conforming to the dimensions shown in Figure 4. Tyco
Electronics does not manufacture or market these
gages.
