3. SETUP ADJUSTMENTS AND TEST
The adjuster (insertion rod) of the wire inserter is pre-
set for 18–26 AWG wire. If the wire is being inserted
too deeply or not deeply enough inside the contact, it
may be necessary to adjust the air pressure or the
depth of the wire inserter.
3.1. For Electric Power Unit 931800–1
If the wire is inserted too deeply, refer to the proce-
dure in Paragraph 3.3, Wire Insertion Depth
Adjustment.

1. Determine the wire size, and select the
appropriate color–coded connector.
2. Using a small knife, cut off the wire retainers
(strain relief). This will provide a clear view for
inspecting the connector for a properly terminated
wire in the contact. See Figure 2.
3. Place connector in tool and make a test
termination using procedure described in Section
4, TERMINATING PROCEDURE, Steps 1 through
6. If the connector cannot be inserted into the
head, or if the connector is too loose in the head,
loosen the two screws on the insert housing (see
Figure 1) and adjust the insert housing until the
connector fits properly in the head.
4. Push the connector out of the right side of the
head.
5. Inspect termination in accordance with Section
5, INSPECTION, Steps 1 through 6.

If the wire is inserted too deeply, refer to the proce-
dure in Paragraph 3.3, Wire Insertion Depth
Adjustment.
3.3. Wire Insertion Depth Adjustment
A. Wire Too Deep
If the wire is inserted too deep in the wire contact slot,
remove the head from the tool, and turn the adjuster
clockwise one–sixth of a revolution. The wire insertion
depth will be reduced by approximately 0.20 [.008].
Repeat the test procedure as described in Paragraph
3.1.
1. Perform the procedure outlined in Paragraph
3.1, For Pistol Grip Manual Handle Assembly,
Steps 1 through 4.
2. Inspect termination to ensure that conductor is
terminated past the lead–in transition and is
positioned about halfway into the contact slot. See
Figure 2.
3. Inspect termination to ensure that insulation is
2.29 to 2.74 [.090 to .108] beyond the front contact
beam.
4. If, upon inspection, it is determined that the wire
is not inserted deeply enough, increase the air
pressure by 69 kPa [10 psi], and repeat the
termination and inspection procedure. Continue in
this manner until either the proper insertion depth
is obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is not reached
at 483 kPa [70 psi], return the air pressure to
276 kPa [40 psi] and follow the procedure in
Paragraph 3.3, Wire Insertion Depth Adjustment.
