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. 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 5, REPLACEMENT AND
REPAIR.
2. Inspect head assembly for worn, cracked, or
broken dies. If damage is evident, return the tool to
TE for evaluation and repair. See Section 5,
REPLACEMENT AND REPAIR.
C. Crimp Height Inspection
This inspection requires the use of a micrometer with
a modified anvil. TE does not manufacture or market
these gages, however TE recommends a modified
micrometer (Crimp Height Comparator
RS--1019--5LP).
Proceed as follows:
1. Select a contact and wire for the crimping
chamber.
2. Refer to Section 3, CRIMPING PROCEDURE,
and crimp the contact accordingly.
3. Using the crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to that height, the tool is
considered dimensionally correct. If not, the tool
must be returned for evaluation and repair. See
Section 5, REPLACEMENT AND REPAIR.
For additional information concerning the use of the
crimp height comparator, refer to instruction sheet
408--7424.

D. Ratchet Inspection
The ratchet feature on these hand tools should be
checked to ensure that the ratchet does not release
prematurely, allowing the crimping dies 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 dies. Proceed
as follows:
1. Select a contact and wire for the tool.
2. Position the contact and wire between the
crimping dies, as described in Section 3,
CRIMPING PROCEDURE.
3. Holding wire in place, squeeze the handles until
the ratchet releases. Hold the handles in this
position, maintaining just enough tension to keep
the dies closed.
4. Check the clearance between the bottoming
surfaces of the crimping dies. If the clearance is
0.025 [.001] or less, the ratchet is satisfactory. If
clearance exceeds 0.025 [.001], the ratchet is out
of adjustment and must be repaired. See Section
5, REPLACEMENT AND REPAIR.
