408-4074
Shear - positions the connector at the proper depth
location and is a shearing surface for the wire.
NOTE
i
The wire inserter and the shear can be rotated
180° to extend the usable life of these parts.
3. SETUP ADJUSTMENTS AND TEST
The insertion rod adjuster is preset for wire sizes 22
through 26 AWG. If, after a termination, the wire is
inserted too deeply or not deeply enough inside the
contact, it may be necessary to adjust the depth of the
wire inserter.
3.1. For Pistol Grip Manual Handle Assembly
1. Select the appropriate cable size and prepare the
cable as shown in Figure 2.
2. Select a connector and place it in the tool. Make
a test termination using the procedures described in
Section 4, TERMINATING PROCEDURE.
NOTE
i
The connector may be loaded and indexed
(manually) from either side of the tool.
Figure 2
3. Remove terminated connector.
4. Inspect the connector for proper termination
using the inspection requirements in Figure 5.
If the wire insertion depth is incorrect, proceed to
Paragraph 3.2, Wire Insertion Depth Adjustment.
3.2. Wire Insertion Depth Adjustment.
• If the wire is too deep in the contact slot: Remove
the head and turn the adjuster CLOCKWISE. Refer
to Figure 3. A 1/6-revolution adjustment will reduce
the wire insertion depth by approximately 0.41 mm
[.016 in.]. Repeat steps 2, 3, and 4 of Paragraph 3.1
until the desired insertion depth is attained.
• If wire is not deep enough in contact slot: Remove
the head and turn the adjuster COUNTER-
CLOCKWISE. Refer to Figure 3. A 1/6-revolution
adjustment will increase the wire insertion depth by
approximately 0.41 mm [.016 in.]. Repeat Steps 2,
3, and 4 of Paragraph 3.1 until the desired insertion
depth is attained.

4. TERMINATION PROCEDURE
Multi-pair copper-conductor cables must be prepared
as follows:
1. Strip the cable jacket and untwist the individual
conductors to the dimension shown in Figure 2.
2. Insert connector into the terminating head (from
either side) and position the connector so that the
two terminals are aligned under the two wire slots.
NOTE
i
The terminating head will terminate two wires at
the same time. Since the connector must be
manually located and advanced, make sure that
the proper terminals are located under the wire
slots of the connector.
3. Select a pair of wires; then insert each wire into
the appropriate wire slot that corresponds with the
proper color code. Insert the wire until the twist of
the wire pair is against the cover. See Figure 4.
NOTE
i
The wire ends must be visible from the back of the
terminating head to ensure there is enough wire to
shear.
4. Squeeze the cam handle of the pistol grip handle
assembly until the ratchet releases. This will shear
the wires and insert the wires into the wire slots of
the connector.
