6.2. Periodic Maintenance
Regular inspections should be performed by your
quality control personnel with a record of these control
inspections remaining with the personnel responsible
for the tool. TE recommends one inspection a month;
however, operator training and skill, amount of use,
ambient working conditions, and your company's
established standards are all factors in establishing
frequency of inspections.
These inspections should be performed in the
following sequence:
1. Remove any accumulated film with a suitable
cleaning agent that will NOT affect plastic material.
2. Make sure all components are in place and
properly secured. See Figure 7.
3. Make a few test terminations and inspect the
terminations in accordance with Section 5,
INSPECTION.
4. Check for chipped, cracked, worn, or broken
areas. If damage is evident, repair if necessary. See
Section 7, REPLACEMENT AND REPAIR.
6.3. Occasional Maintenance
Because this tool shears wires before insertion, wear
of the shearing surfaces can be expected as a normal
operating condition. Since wire size, insulation
diameter and hardness are all variables, a reasonable
life expectancy of the shearing edges cannot be
determined.
Shearing occurs along the edge where the inserter
rides against the shear. When the operator of the tool
starts to notice wire ends that are not cleanly cut, or if
excessive force becomes necessary to shear the
wires, it is time to change or replace the two
components that do the shearing. Refer to Figure 6
and proceed as follows:
1. To change the position of the shear, remove the
cover of the terminating head by loosening the two
4-40 socket head cap screws which hold the head
in place. Carefully, lift off the cover. See Figure 6.
NOTE ^{DO NOT lift the inserter off with the cover.}
i
2. Lift off the inserter. (Make note as to which side is
in contact with the shear.)
3. Lift off the shear. Rotate the shear 180° so that
the surface that was facing down is now facing up.
Place the shear back in place.
4. Replace the inserter, making sure that the
surface (that was in contact with the shear when
disassembling the tool) is now rotated 180° away
from the shear.

Make sure that the roll pin going through the
inserter is engaged in the slot of the link.
5. Replace the cover. Align the edges of the
terminating head, shear, and cover and tighten the
two 4-40 socket head cap screws.
NOTE
i
This procedure can only be done one time for each
set of inserter and shear. When the second
shearing edge becomes dull, replacement of the
inserter and shear will be necessary.
CAUTION
!
Attempts to sharpen the inserter or shear might
cause the inserter to be out of position during wire
insertion and cause damage to the connector or
tool.
